Subaru Ascent 1st gen (WP) Problems, Recalls & Lemon Law

warning light; recall notice; repeated dealer repair

NHTSA recall 18V508000 covers 2019 Ascent vehicles with missing B-pillar spot welds that compromise crash-protection structure. If Subaru's remedy (vehicle replacement for missing welds) was not completed or was improperly performed and the vehicle remained unsafe, the owner may have a Song-Beverly claim. Any unresolved structural safety defect covered by a recall that the dealer fails to remedy within a reasonable time and number of attempts triggers the Act's buyback or replacement obligations.

Subaru will notify owners, and dealers will inspect the vehicle to check for missing spot welds. If the welds are missing, the vehicle will be replaced, free of charge. The recall began July 31, 2018. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WT

clunking from drivetrain; loss of drive power; vehicle may roll when parked

NHTSA recall 19V519000 addresses the 2019 Ascent's front driveshaft center-support bolt loosening, which can allow the driveshaft to disconnect at highway speed. This is a crash-risk safety defect. If the driveshaft assembly replacement remedy was not completed or if symptoms (vibration, clunking) recurred after repair, each return to the dealer counts toward Song-Beverly's repair-attempt threshold, and the safety severity strengthens the 'substantial impairment' showing.

Subaru will notify owners, and dealers will replace the driveshaft assembly, including the center support brace, 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 WUI-94.

transmission shifts unexpectedly; hesitation; harsh shift; transmission warning

NHTSA recall 19V855000 addresses a CVT hydraulic pressure sensor defect in 2019 Ascent vehicles that can cause the drive chain to lose tension, resulting in sudden loss of drive power at any speed. Superseded by recall 21V955000 (iss-08), which expanded coverage to 2019-2020 MY and required additional inspection. Owners who experienced loss-of-drive events before or after the remedy may have a lemon-law claim if the condition recurred or if the TCU reprogramming remedy proved insufficient.

Subaru will notify owners, and dealers will reprogram the transmission control unit. The hydraulic sensor harness will be replaced on vehicles with certain stored diagnostic trouble codes. In addition, any vehicle confirmed to have experienced low drive chain tension will have the transmission assem

engine knocking; engine stalls; sudden loss of power; check engine light; engine failure recall

NHTSA recall 19V856000 covers 2019 Ascent vehicles where the aluminum PCV valve can separate and allow debris to enter the FA24F engine, causing power loss while driving. If the PCV valve was found separated and a short-block engine replacement was required, that is a substantial repair event. Any recurrence of oil consumption or engine damage after the recall remedy — potentially linked to the FA24F piston ring issue (iss-13) — strengthens a Song-Beverly claim significantly.

Subaru will notify owners, and dealers will inspect and replace the PCV valve, free of charge. If the PCV valve has separated and the components cannot be found, the short block engine will be replaced, free of charge. The recall began January 31, 2020. Owners may contact Subaru customer service at

engine stalls while driving; vehicle will not start; loss of power; fuel pump recall

NHTSA recall 20V218000 addresses 2019 Ascent vehicles with a low-pressure fuel pump that may fail, causing engine stall and inability to restart. Engine stall without restart at speed creates a real crash risk. This recall was later supplemented by 21V587000 (iss-06), which expanded coverage. Owners who experienced stall events before the recall remedy was available, or who had the pump replaced but experienced subsequent fuel-delivery issues, should document each incident as a separate repair attempt under Song-Beverly.

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

NHTSA recall 21V587000 expands the low-pressure fuel pump defect coverage to 2019-2020 Ascent vehicles (broadening from recall 20V218000 which covered 2019 only). If an Ascent owner experienced a stall event, had the pump replaced under 20V218000, and then experienced a second stall requiring the 21V587000 remedy, that two-recall repair history is compelling evidence for a Song-Beverly repeat-repair claim on a safety defect.

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.

sticky steering; steering wheel feels stuck; increased steering effort; steering recall

NHTSA recall 21V954000 covers 2020 Ascent vehicles with improperly fitted front tie rod ends that may separate from the housing, causing sudden loss of steering control. This is among the most serious safety recalls in the Ascent's history — steering loss at highway speed is immediately life-threatening. Any owner whose 2020 Ascent had steering abnormalities (wandering, vibration, pulling) before this recall was remedied has strong grounds for a Song-Beverly claim if the dealer dismissed those complaints.

Dealers will replace the left and right front tie rod ends and housings, free of charge. Owner notification letters were mailed February 7, 2022. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRL-21.

transmission shifts unexpectedly; hesitation; harsh shift; transmission warning

NHTSA recall 21V955000 expands the CVT chain-tension defect to 2019-2020 Ascent and covers a TCU programming error that can allow the clutch to engage before the drive chain is properly clamped, potentially causing the chain to slip and break. This recall supersedes 19V855000 and requires a new remedy even on previously repaired vehicles. Owners who presented CVT complaints between the two recalls — or who had transmission replacements — have a documented repeat-repair history that supports a Song-Beverly claim.

Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters were mailed August 19, 2022. This recall in

warning light; recall notice; repeated dealer repair

NHTSA recall 22V907000 is the Ascent's most severe safety defect: a loose PTC heater ground bolt on 2019-2022 models can cause the ground terminal to melt, creating a vehicle fire risk. Subaru's interim remedy instructed owners to park away from structures and not leave the vehicle unattended while running — a stark acknowledgment of the fire hazard. Any owner who experienced smoke, a burning smell from the dash, or an actual fire event before or after the recall remedy has an extremely strong Song-Beverly and potential tort claim. This defect is the type that supports punitive damages under California law.

Owners are advised to park their vehicle away from structures and to avoid leaving the vehicle unattended while the engine is running. An owner who notices or smells smoke coming from the dash or driver's footwell area should immediately stop operating the vehicle and turn the ignition switch to the

warning light; recall notice; repeated dealer repair

NHTSA recall 23V258000 covers 2023 Ascent vehicles with 20-inch wheels where the internal tire bead was damaged during factory mounting, risking sudden air pressure loss. This recall requires replacement of all four tires. Owners who experienced a blowout or unexpected pressure loss before receiving this recall remedy — or who were denied a tire-related warranty claim before the recall was announced — have a credible Song-Beverly claim for a safety defect the manufacturer was obligated to disclose.

Dealers will replace all four tires, free of charge. Owner notification letters are expected to be mailed June 6, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRH-23.

front suspension noise; stabilizer bar loose; vehicle pulls or clunks

NHTSA recall 23V392000 covers 2023 Ascent vehicles with improperly tightened ball joint castle nuts on the front lower control arm. Separation while moving causes immediate loss of vehicle control. Owners who noticed suspension clunking, play, or handling abnormalities before the recall remedy was applied — and whose dealers initially said the suspension 'checked out fine' — should document those repair visits. Each dismissed complaint that preceded the recall remedy is additional evidence for a Song-Beverly claim.

Dealers will inspect and, if necessary, replace the lower control arm, free of charge. Owner notification letters are expected to be mailed June 30, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRJ-23.

clunking from drivetrain; loss of drive power; vehicle may roll when parked

NHTSA recall 23V647000 covers 2023 Ascent (and Outback, Legacy, Impreza) vehicles with the same driveshaft center-support bolt loosening defect as recall 19V519000 (iss-02) — remarkable that Subaru produced vehicles with the same manufacturing defect four years later. This recurrence pattern is relevant to lemon-law cases: if a 2023 Ascent owner experienced driveshaft symptoms before the recall was issued, and Subaru's dealer dismissed the complaint, the manufacturer's prior knowledge of this specific failure mode (from the 2019 recall) supports a Song-Beverly claim.

Dealers will clean the bolt mounting surfaces of the center support brace and install new bolts, free of charge. Owner notification letters were mailed November 20, 2023. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRN-23.

Oil level drops 1 quart or more between oil changes; burning oil smell from engine bay; blue or gray smoke from exhaust under acceleration; low oil warning light illuminates; dealer says oil consumption is 'within spec'; engine knock after oil level drops

Excessive oil consumption requiring engine disassembly is a substantial impairment of use and value under Cal. Civ. Code §1793.2. If dealers initially deny the defect as 'normal consumption' and the owner returns multiple times before the TSB-directed repair is performed — or if the repair fails to resolve the consumption — each visit to the dealer for this issue counts toward the Song-Beverly repair-attempt threshold.

Dealer-supervised oil consumption test (minimum 1,200 miles); if confirmed, piston and piston ring replacement per TSB 16-119-20R. Check PCV valve as contributing factor.

Vibration or shudder felt through the cabin at highway cruise speeds (55–75 mph); harsh lurch or jerk when accelerating from a stop; hesitation when merging onto freeway; transmission slipping sensation; CVT whine or grinding noise; transmission enters limp mode; check engine light with CVT-related codes

CVT shudder that persists through multiple software updates or recurs after repair is a textbook repeat-repair defect under Song-Beverly. If the dealer has reprogrammed the TCU more than once without a lasting fix, or if a CVT assembly replacement was required, the owner likely has a credible lemon-law claim. The class-action context provides additional evidence that Subaru was on notice of the defect.

TCU software recalibration per TSB 16-109-21; road test required to verify elimination. Persistent cases may require torque converter or full CVT assembly replacement.

Center touchscreen goes black while driving; system reboots mid-trip taking 3–5 minutes to recover; backup camera fails to display when reversing; Apple CarPlay or Android Auto disconnects unexpectedly; climate controls unresponsive during reboot; audio cuts out; navigation loses route during screen freeze

Loss of backup camera display while reversing is a safety impairment, not merely an inconvenience, and strengthens the Song-Beverly 'substantial impairment' standard. If the infotainment freeze recurs after a software update and head unit replacement is performed twice or more within the warranty period, the pattern supports a lemon-law claim on this defect alone.

Apply Starlink software update per TSB 15-273-21. If freeze recurs post-update, head unit replacement authorized. Owners should note: the backup camera failure during reboot is a safety-adjacent issue that strengthens the repair record.

Car slams on brakes with no obstacle in the road; vehicle decelerates suddenly on the highway without warning; EyeSight warning light illuminates after hard stop; system automatically disables itself after false activation; braking event occurs under bridges, in tunnels, or in dappled-light tree cover; false pre-collision alert triggers with no car ahead

Unintended braking at highway speed is a safety defect that substantially impairs the vehicle's safe operation — a critical element under Cal. Civ. Code §1793.2. Because EyeSight is standard equipment on all Ascent trims, phantom braking that resists firmware repair directly supports a Song-Beverly claim. Each dealer visit where the technician cannot replicate the event (a common outcome) still counts as a repair attempt if the complaint is documented on the repair order.

EyeSight camera firmware update per TSB 15-286-22. Inspect windshield for distortion at camera mounting location. If phantom braking persists, EyeSight camera module replacement may be required.

Dead battery after vehicle sits overnight or for a day; jump start required to start car; interior dome light stays on after doors are closed; battery warning light after restart; repeated battery replacements under warranty; dealer finds no parasitic draw during inspection

Repeat battery failure or parasitic draw that cannot be resolved after multiple dealer visits may support a Song-Beverly claim if the condition recurs within the warranty period. Owners should obtain written repair orders each visit, including visits where the dealer 'cannot duplicate' the drain — those still count as repair attempts.

Inspect dome light and door-ajar switch function; apply BCM software update if available. Check Starlink module sleep current. Replace battery if damaged by deep-cycle discharge.

Air conditioning blows warm or hot air; A/C system stops cooling; refrigerant charge depletes repeatedly; dealer finds condenser punctured or corroded; A/C failure recurs after condenser replacement; rattling or hissing from front of vehicle under hood

Recurrent A/C condenser failure — particularly two or more replacements within the warranty period — is a 'repeat repair' pattern that can support a Song-Beverly claim when A/C failure substantially impairs the vehicle's use during warm-weather months. Owners in California's hot inland regions especially may meet the 'substantial impairment' standard.

Condenser replacement and refrigerant recharge. If condenser fails repeatedly, inspect for debris-impact pattern and consider condenser guard installation. Covered under bumper-to-bumper warranty within 3 years/36,000 miles.

Water dripping from headliner; wet front floor carpets after rain; musty or mold smell inside cabin; water pooling in driver or passenger footwell; electrical malfunctions following interior soaking; sunroof drains overflow visible on door sills

Water intrusion that reaches electrical components — wiring, BCM, fuse box — can substantially impair the vehicle and supports the Song-Beverly 'safety or reliability' standard. If water damage causes secondary electrical faults and those faults require multiple repair visits, the combined repair history may qualify under Song-Beverly.

Flush and clear sunroof drain tubes; inspect drain routing for kinks. If water has contacted electrical components, inspect BCM, fuse box, and wiring harness. Dealers may apply anti-debris sealant to drain tube openings.
