Brake System Defect — Recall 15V366 (EyeSight/ESC Software, 2015)
brake pedal problem; reduced braking; unexpected braking; brake warning light
2015-2019 Subaru Legacy: CVT failure, windshield cracking, oil consumption, EyeSight phantom braking, 11 NHTSA recalls. California lemon law help.
You bought a Subaru Legacy because the brand stands for something: all-weather safety, family-tested reliability, and a boxer engine owners have trusted for decades. EyeSight promises to watch the road when you can't, the CVT promises efficiency, and Starlink keeps you connected. Instead, thousands of 2015-2019 Legacy owners found themselves back at the dealer, for cracked windshields that appeared overnight, CVT transmissions that shuddered or failed before 80,000 miles, and an oil-burning FB25 with a defect Subaru had already acknowledged on the prior generation.
The sixth-generation Legacy accumulated eleven NHTSA recalls: brake-assist software, driveshaft separation, steering column defects, rearview camera failures, body spot-weld defects, and two low-pressure fuel pump campaigns. Many overlapped. A 2015 owner could receive 15V366 (EyeSight software), 15V502 (propeller shaft), and 16V251 (brake fluid moisture) in the same year.
Beyond recalls, NHTSA complaints tell a more personal story. Windshield cracking (sometimes within a month of purchase, sometimes three times in a year) is the dominant complaint category for 2015, 2017, and 2019 model years. Each cracked windshield on an EyeSight-equipped Legacy requires dealer camera recalibration, turning a glass job into a $300-$500 dealer visit. CVT shudder, metallic grinding, AT OIL TEMP warnings, and full CVT replacements before 50,000 miles appear throughout NHTSA records. The FB25 oil-consumption defect (acknowledged and remedied on the 2011-2014 generation with an 8-year warranty extension) carried into 2015-2019 without a redesigned ring package.
California law exists for exactly this. If your Legacy has spent time on a lift for these issues, your repair orders may be more valuable than you realize.

brake pedal problem; reduced braking; unexpected braking; brake warning light
This recall addresses an EyeSight / electronic stability-control software defect that could cause unexpected braking or loss of brake assist on 2015 Legacy models. Under California's Song-Beverly Act, a safety-system defect that recurs after a dealer's software reflash constitutes a covered warranty repair attempt. Owners who returned to the dealer two or more times for the same unexpected-braking symptom within the warranty period may be within eligibility range.
Subaru will notify owners, and dealers will reprogram the driver assist system, free of charge. The recall began on July 20, 2015. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WQS-54.
clunking from drivetrain; loss of drive power; vehicle may roll when parked
Recall 15V502 involves transmission-oil leakage from a deformed propeller-shaft seal cap that could cause complete loss of drive power and an unsecured park position on 2015-2016 Legacy AWD models. A drivetrain failure at highway speed — or a car that rolls when supposedly in Park — is a safety defect under Song-Beverly. Owners who experienced multiple drivetrain clunk or no-drive events within the warranty period, even after a propeller-shaft replacement under this recall, should document every dealer visit carefully.
Subaru will notify owners, and dealers will replace the propeller shaft, free of charge. The recall began on August 28, 2015. Owners may contact 1-800-782-2783. Subaru's number for this recall is WQU-56.
clunking from drivetrain; loss of drive power; vehicle may roll when parked
Recall 15V794 is a distinct driveshaft defect on certain 2016 Legacy vehicles: improperly tightened securing nuts that could allow the driveshaft to separate. Unlike 15V502, the defect here is a fastener torque error, not a seal failure. If a 2016 Legacy owner experienced drivetrain clunking, shimmy, or loss of propulsion after the recall inspection, and the dealer closed the repair order with 'unable to duplicate' or minimal action, those records support a Song-Beverly claim based on recurring safety-system failure.
Subaru has notified owners, and dealers will inspect the fastening nuts, and tighten or replace them, as necessary, free of charge. The recall began on December 10, 2015. Owners may contact Subaru customer service at 1-856-488-8500. Subaru's number for this recall is WQV-57.
brake pedal problem; reduced braking; unexpected braking; brake warning light
Recall 16V251 covers a separate brake-fluid moisture defect that degraded ESC performance on specific 2015 Legacy vehicles manufactured July 20, 2015. If a dealer performed a brake-fluid flush under this recall and the owner later experienced brake-feel complaints or ESC warnings, those subsequent visits create independent repair-attempt records. Song-Beverly counts each warranty repair visit — a documented return trip after a recall remedy is significant.
Subaru will notify owners, and dealers will perform an ABS activation, then flush and replace the brake fluid, free of charge. The recall began on May 20, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTC-64.
sticky steering; steering wheel feels stuck; increased steering effort; steering recall
Recall 16V292 addresses an improperly machined steering column on 2016-2017 Legacy models that caused the steering wheel to bind or require excessive effort — a loss-of-control risk. Sticky or heavy steering is a classic Song-Beverly defect: it is safety-critical, owner-detectable, and often intermittent (making 'cannot duplicate' responses common at the dealer). Two or more visits for hard steering within the warranty period, with the recall remedy applied but symptoms continuing, satisfies the reasonable-number-of-attempts threshold.
Subaru will notify owners, and dealers will inspect the lot number on the steering column, replacing the steering column, as necessary, free of charge. The recall began May 13, 2016. Owners may contact Subaru customer service at 1-800-782-2783 or by visiting http://www.wtd65.service-campaign.com. Su
sticky steering; steering wheel feels stuck; increased steering effort; steering recall
Recall 16V716 targets a specific 2017 Legacy production window where the knee-guard bracket weld to the steering beam assembly was defective. An improperly attached steering beam affects crash-safety structural integrity, not just steering feel. If a 2017 Legacy owner returned multiple times for steering-column noise, steering-column movement, or airbag warning lights related to the steering assembly, those visits may independently support a Song-Beverly claim even if the underlying recall inspection was completed.
Subaru will notify owners, and dealers will inspect the knee guard welding on each vehicle's steering beam, replacing the beam as necessary, free of charge. The recall began November 14, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTL-72.
warning light; recall notice; repeated dealer repair
Recall 18V773 covers a software error causing the 2018 Legacy's low-fuel warning to fail and the miles-to-empty readout to show a positive number when the tank is empty — a defect with real stranding risk. While classified Functional (not Safety), an owner who ran out of fuel due to an inaccurate gauge, or who returned to the dealer for the same inaccurate-display symptom after the software reflash, has documented warranty repair attempts that matter under Song-Beverly — especially combined with other open issues on the same vehicle.
Subaru will notify owners, and dealers will reprogram the combination meter software, free of charge. The recall began February 20, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WTW-82.
backup camera blank; screen goes black in reverse; rearview camera distorted
Recall 18V935 addresses a software fault causing the 2018 Legacy's rearview camera to show a blank screen on startup — a federally mandated rear-visibility safety system. A blank backup camera is a safety defect under both FMVSS 111 and Song-Beverly. If the dealer reflashed the audio software under this recall and the camera continued to intermittently black out, each additional dealer visit is a documented repair attempt. Two or more post-recall visits for the same blank-camera symptom within the warranty period is textbook eligibility.
Subaru has notified owners, and dealers will reprogram the audio system display software, free of charge. The recall began on February 5, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WTZ-85.
warning light; recall notice; repeated dealer repair
Recall 19V493 covers improperly applied spot welds on the cowl-panel duct of certain 2019 Legacy vehicles, reducing structural body strength. Notably, Subaru's own remedy included the option to repurchase affected vehicles — an acknowledgment of defect severity. If a 2019 Legacy owner was offered a repurchase under this recall but declined, or was told repair was insufficient, that record alone may establish a Song-Beverly foundation. An owner who experienced structural noise, water intrusion, or body-rigidity concerns should preserve all repair documentation.
Subaru will notify owners, and dealers will inspect the vehicles and repair or repurchase the vehicle, as necessary, free of charge. The recall began July 26, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUH-93.
engine stalls while driving; vehicle will not start; loss of power; fuel pump recall
Recall 20V218 covers a potentially inoperative low-pressure fuel pump on 2019 Legacy models that could cause engine stall or no-start — a loss of propulsion risk at highway speeds. Under Song-Beverly, an engine stall while driving is a safety defect. Owners who experienced multiple stall events or extended dealer downtime waiting for the replacement fuel pump (supply constraints were common with this recall) may count time-out-of-service days toward the 30-day threshold, independent of the repair-attempt count.
Subaru will notify owners, and dealers will replace the low pressure fuel pump, free of charge. The recall began June 4, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRD-20.
engine stalls while driving; vehicle will not start; loss of power; fuel pump recall
Recall 21V587 is a broader low-pressure fuel-pump recall (Subaru campaign WRG-21) covering 2018-2019 Legacy along with other Subaru models. This recall and 20V218 (WRD-20) address related but distinct pump-failure modes. An owner of a 2018-2019 Legacy who received notice of both recalls, experienced a stall or no-start, and required repeated dealer visits for fuel-system diagnosis is accumulating independent repair attempts across two separate recall campaigns — a strong Song-Beverly posture even if each individual campaign had only one visit.
Dealers will replace the low-pressure fuel pump, free of charge. Owner notification letters were mailed September 24, 2021. Subaru and Toyota owners may call customer service at 1-844-373-6614. Subaru's number for this recall is WRG-21.
oil light comes on between oil changes; low oil warning at less than 3,000 miles; using more than one quart of oil per 1,000-3,000 miles; burning oil smell from engine; blue smoke on startup; dealer requests oil-consumption study; no external oil leak visible
Excessive oil consumption on the FB25 is a recurring powertrain defect acknowledged by Subaru on the predecessor generation. Under Song-Beverly, a defect that requires repeated dealer visits for oil-consumption studies without resolution — or that results in engine damage from oil starvation — constitutes an unrepaired warranty defect. California owners whose dealers conducted multiple consumption studies and refused to authorize ring or short-block replacement may have repair-attempt records sufficient to support a claim.
Dealer-initiated oil-consumption study (typically 1,000-mile intervals); if consumption exceeds Subaru's threshold, piston ring replacement or short-block replacement under powertrain warranty. If vehicle is out of warranty, owner may cite the precedent of the 2011-2014 extended-coverage program. Interim: more frequent oil-level checks and top-offs.
CVT shudders at low speed or when accelerating from a stop; transmission slipping or jerking between 15-35 mph; metallic grinding noise from transmission; AT OIL TEMP warning light illuminates; loss of power on grades; CVT replaced under warranty; received Subaru CVT warranty extension notice; rough idle at stops
CVT shudder or failure is a Drivability/Reliability defect that directly impairs safe vehicle operation. Under Song-Beverly, a transmission defect requiring multiple dealer visits — especially one where the dealer performs a fluid service and the shudder returns — counts as repeated unsuccessful warranty repair attempts. Owners who experienced CVT replacement followed by recurrence, or who were told the shudder was 'normal CVT feel,' have documented dealer acknowledgment of the defect with disputed resolution.
CVT fluid drain-and-fill (interim; may suppress shudder temporarily); TCM software update if available; CVT assembly replacement under powertrain warranty. Subaru dealer warranty coverage on CVT typically 5 years / 60,000 miles standard powertrain; some owners received extended coverage via warranty-extension program notification.
windshield cracks without impact; crack appears overnight while parked; loud pop followed by crack spreading across windshield; multiple windshield replacements within 12-18 months; crack starts at base near wiper area or lower driver corner; EyeSight system disabled after crack; EyeSight recalibration required after each windshield replacement
Multiple windshield replacements — particularly when each requires EyeSight recalibration at the dealer — constitute multiple documented warranty or out-of-warranty repair events. If the cracks occur within the 3-year / 36,000-mile bumper-to-bumper warranty and the dealer refuses coverage on grounds of road-hazard exclusion, California's implied warranty provisions may still apply when the defect is clearly systematic and not attributable to owner misuse. Owners with three or more windshield replacements in the first 24 months should document every repair order and EyeSight recalibration charge.
Windshield replacement (OEM glass required for EyeSight vehicles to maintain camera alignment) followed by EyeSight camera recalibration at the dealer. Insurance typically covers glass; however, multiple replacements on the same vehicle may be contested. Subaru has not issued a formal recall or extended coverage for this defect.
car slams on brakes without driver input; sudden unintended deceleration on highway; EyeSight pre-collision braking activates with no obstacle present; cruise control disengages unexpectedly; vehicle lurches forward or brakes hard at low speed in parking lot; EyeSight warning light illuminates; EyeSight disabled by dealer but problem recurs
An ADAS system that applies emergency braking without driver input is a safety defect. Under Song-Beverly, unintended deceleration at highway speed — particularly when it has caused or nearly caused a rear-end collision — is the type of safety-critical defect that California courts treat seriously. If a dealer acknowledges the phantom-braking event on a repair order but cannot replicate it and closes with 'no fault found,' that visit still counts as a documented repair attempt. Two or more such visits, especially following a windshield replacement that required EyeSight recalibration, builds the pattern.
EyeSight camera recalibration; software update to collision-avoidance detection parameters if available; in severe cases, dealer may disable EyeSight pre-collision braking and advise owner to drive with the feature off. Windshield replacement and recalibration required if camera alignment has been disturbed.
touchscreen goes black while driving; infotainment system freezes and requires hard reset; backup camera fails when screen is frozen; navigation stops responding; Bluetooth phone connection drops mid-call; radio/audio system restarts spontaneously; screen unresponsive to touch for 30 seconds or more; system reboots on startup
While an infotainment freeze is classified Functional rather than Safety, the Starlink system on the Legacy integrates the backup camera (a federally mandated rear-visibility system) and EyeSight status display. A head unit that repeatedly freezes — taking the backup camera with it — touches safety territory. Under Song-Beverly, multiple dealer visits for the same screen-freeze symptom, even if each is resolved with a software update or reset, constitute repeated repair attempts. Owners whose 2015-2017 Legacy systems freeze regularly and who have no recall remedy available are in a stronger lemon-law posture than those with recall coverage.
Dealer software update to head unit firmware if a current update is available; in severe cases, head unit module replacement. Interim owner workaround: hard-reset by holding power button for 10+ seconds. Note: Recall 18V935 already addressed one software variant on 2018 models — owners of 2015-2017 units with persistent freezing may not have a comparable recall remedy.
battery dead after car sits for 2-5 days; car will not start after a long weekend; jump-start needed repeatedly; battery replaced but drain recurs; dealer says battery tests normal; no parasitic draw found at dealer visit; EyeSight or Starlink modem drawing power when car is off
Recurring battery failure that leaves an owner stranded is a Drivability/Reliability defect covered by the original powertrain and electrical warranty. Under Song-Beverly, the 'cannot duplicate' pattern — where the dealer checks the battery same-day and finds nothing — is precisely the dealer friction the lemon law anticipates. Owners who document every no-start event with a tow or jump-start record, and who present the vehicle for diagnosis three or more times, create a repair-attempt record even without a confirmed root cause on each visit.
Battery load test and replacement (typically first dealer response); follow-up parasitic draw test with all modules monitored over extended period; software updates to Starlink modem or EyeSight controller if available; module replacement in confirmed cases.
oil level drops between service intervals on 3.6R model; engine noise on cold start; ticking or rattling from engine on startup until oil pressure builds; burning oil smell from 3.6R engine; low oil warning light activates early; blue-tinted exhaust smoke under hard acceleration
EZ36 oil consumption follows the same lemon-law analysis as the FB25 (iss-12): if the dealer conducts multiple oil-consumption studies without authorizing ring replacement, and the owner experiences repeat low-oil events within the warranty period, those visits are documented repair attempts. The 3.6R trim is a top-of-line Legacy variant; owners paid a premium for a flagship powertrain and have strong expectations of reliability under Song-Beverly's implied warranty of merchantability.
Oil-consumption monitoring study at dealer; piston ring inspection and replacement if consumption exceeds manufacturer threshold; chain tensioner inspection and replacement if noise persists beyond 10-15 seconds of cold start. Use of 0W-20 full-synthetic oil as specified is required; non-spec oil accelerates ring deposits.

Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act applies to new and used vehicles (sold with a dealer warranty) when a covered defect cannot be repaired after a reasonable number of attempts.
SAFETY DEFECTS: Recalls 15V366 and 16V251 (brake/ESC), 16V292 and 16V716 (steering), 15V502 and 15V794 (driveshaft separation), 20V218 and 21V587 (fuel pump stall), and EyeSight phantom braking are safety defects. California law presumes a reasonable number of attempts exceeded when a vehicle has been in for the same safety defect two or more times.
POWERTRAIN DEFECTS: CVT shudder (iss-13) and FB25 oil consumption (iss-12) fall under Subaru's 5-year / 60,000-mile powertrain warranty. Multiple visits for the same CVT symptom — or repeated consumption studies without authorized repair — are documented repair attempts.
DAYS OUT OF SERVICE: Thirty or more cumulative dealer days across all covered repairs qualifies independently of repair-attempt count. Preserve loaner records, 'vehicle ready' dates, and tow receipts.
BUYBACK: A successful claim typically produces a manufacturer repurchase — purchase price plus taxes and fees, minus a mileage usage offset from the first qualifying repair attempt.
General information only, not legal advice. As of 2026-06-30.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
If the Subaru dealer says it cannot duplicate your Legacy's problem, here is what to do:
1. DOCUMENT BEFORE YOU GO IN. Video the CVT shudder, cracked windshield, frozen Starlink screen, or EyeSight warning. Note the date, mileage, temperature, and road conditions.
2. WRITE THE SYMPTOM IN YOUR OWN WORDS ON THE REPAIR ORDER. Insist the service writer records your complaint precisely. 'CVT shuddering 15-30 mph on acceleration, 3-4 times per week' is more defensible than 'transmission feels rough.' Specific language prevents easy dismissal.
3. CONFIRM THE ROAD-TEST MILEAGE. Zero test-drive miles on the repair order means the dealer did not attempt to replicate a dynamic symptom — that is significant.
4. REQUEST TECHNICIAN NOTES. Raw notes sometimes show the symptom was observed but unresolvable. 'Observed occasional shudder — cannot replicate on demand' is a de facto confirmation.
5. WINDSHIELD CRACKS: Ask whether EyeSight required recalibration. That RO establishes the crack affected the safety camera system — useful if warranty coverage is later disputed.
6. BATTERY DRAIN: Do not bring the car in same-day after a jump-start. Wait 48-72 hours, document the no-start with a tow receipt, then request a multi-hour parasitic draw test — not just a standard battery load test, which will show normal.
7. KEEP EVERY REPAIR ORDER. Song-Beverly allows ROs as evidence years after the events. Scan or photograph every repair order immediately after pickup.
The 2015-2019 Subaru Legacy has one of the more layered defect records in the mid-size sedan segment. Eleven NHTSA recalls — including three separate driveline or brake campaigns in the first model year alone — is a notable volume. The non-recall defects add another dimension: windshield cracking is the dominant owner complaint across nearly every year of the generation, yet Subaru has issued no recall or extended-coverage program for it. The FB25 oil consumption issue is particularly hard to excuse: Subaru acknowledged and remedied the same defect on the 2011-2014 generation. Carrying the same ring design into 2015+ without a fix is difficult to explain to an owner whose dealer just ran a third consumption study without authorizing repair. If you have documented repair visits, the record is worth a professional review.
— The Margarian Law team
If your 2015-2019 Subaru Legacy has been back to the dealer for CVT shudder, windshield cracking, oil consumption, phantom braking, or any recalled defect, you may have options under California law. Margarian Law offers a free case review — no out-of-pocket cost.
Spontaneous windshield cracking is the most-reported defect for the 2015-2019 Legacy in the NHTSA complaint database — the visibility/wiper category logged 30-46 complaints per model year, more than any other system. Owners consistently describe cracks appearing overnight while the car is parked, starting from the base of the windshield near the wiper-heater strip or the lower driver corner, and spreading across the full width within hours. The likely mechanism is thermal stress concentrated at the wiper-heater element, combined with glass that propagates small chips into full cracks more readily than expected. On EyeSight-equipped models, every windshield replacement requires an EyeSight camera recalibration at the dealer — adding $100-$300 per incident. Subaru has not issued a recall or extended-coverage program for this defect. If you have had two or more windshields replaced within the warranty period and the dealer denied warranty coverage on the glass, document each event carefully.
Yes — CVT shudder is a well-documented pattern across the 2015-2019 Legacy. NHTSA complaint records for the POWER TRAIN component describe shuddering between 15-35 mph on acceleration from a stop, metallic grinding sounds, AT OIL TEMP warning lights, and full CVT assembly failures before 50,000 miles. The Legacy uses the Lineartronic TR580 CVT in 2.5i trims and the TR690 in the 3.6R — both have been cited in complaints. One owner specifically reports receiving a Subaru CVT warranty-extension notice before the transmission failed outright, confirming Subaru's awareness of the issue. The standard Subaru powertrain warranty covers the CVT for 5 years or 60,000 miles. If your CVT was repaired under warranty and the shudder returned, or if you experienced the AT OIL TEMP warning on more than one occasion, those are documented repair attempts that may support a Song-Beverly claim.
Many owners of 2015-2019 Legacy models with the FB25 2.5L four-cylinder engine report excessive oil consumption — using more than one quart per 2,000-3,000 miles without any visible external leak. The symptom typically surfaces as the oil-level warning light activating between scheduled oil changes. The root cause is oil-control piston rings that can become fouled with carbon deposits, reducing their ability to scrape oil off the cylinder walls. This is not a new problem for Subaru's flat-four design: Subaru previously extended the powertrain warranty on 2011-2014 Outback and Legacy models with the same FB25 engine to cover this defect up to 8 years / 100,000 miles, including piston ring and short-block replacement. The 2015-2019 BN-generation Legacy carries the same engine without a redesigned ring package. If your dealer has conducted one or more oil-consumption studies but has not authorized ring or short-block replacement, and the vehicle is still within warranty, push for escalation and document every visit.
The 2015-2019 Subaru Legacy has eleven NHTSA recall campaigns: (1) 15V366 — EyeSight/ESC software causing unexpected braking (2015); (2) 15V502 — propeller-shaft seal oil leak, loss of drive (2015-2016); (3) 15V794 — improperly tightened driveshaft nuts (2016); (4) 16V251 — brake-fluid moisture degrading ESC (2015); (5) 16V292 — improperly machined steering column, heavy steering (2016-2017); (6) 16V716 — knee-guard bracket weld defect on steering beam (2017); (7) 18V773 — fuel-gauge software error, inaccurate low-fuel warning (2018); (8) 18V935 — rearview camera blank-screen software defect (2018); (9) 19V493 — cowl-panel spot-weld defect, reduced body strength (2019); (10) 20V218 — low-pressure fuel pump failure, stall risk (2019); (11) 21V587 — low-pressure fuel pump failure, stall risk (2018-2019). Check NHTSA.gov with your VIN to confirm which campaigns apply to your specific vehicle and whether the remedy has been completed.
EyeSight phantom braking — where the system applies emergency braking without a real obstacle present — is reported in NHTSA complaints across the 2015-2019 Legacy. EyeSight uses stereo cameras mounted at the top-center of the windshield to detect vehicles and obstacles. It can activate false positives near overpasses, road markings, opposing headlights, or after any event that disturbs camera alignment (such as a windshield replacement). NHTSA complaints include a Sudden Unintended Deceleration event on a major highway that stopped the vehicle in the left lane and resulted in a rear-end collision. If your EyeSight has activated emergency braking without cause, bring the vehicle to the dealer and ask them to document the event on the repair order. An ADAS system that falsely applies emergency braking at highway speed is a safety defect under California law — and the 'we cannot duplicate it' response to a documented phantom-braking event is one of the most common dealer friction points in Legacy-related lemon-law claims.
Yes — a 2015-2019 Subaru Legacy can qualify for protection under California's Song-Beverly Consumer Warranty Act if a defect covered by the manufacturer's warranty has not been repaired after a reasonable number of attempts. Based on the documented defect record for this generation, the most common qualifying patterns include: (1) CVT shudder returned after transmission service or replacement — two or more visits for the same transmission symptom within the warranty period; (2) multiple EyeSight phantom-braking events documented on repair orders, even with 'cannot duplicate' outcomes; (3) oil-consumption studies conducted two or more times without authorized engine repair while still under powertrain warranty; (4) a fuel pump stall event under Recalls 20V218 or 21V587 followed by a recurrence; or (5) cumulative dealer time of 30 or more days for any combination of covered repairs. Eligibility depends on your specific repair history, warranty timing, and documentation. A free case review can help assess whether your Legacy's records are sufficient.
