2022–2025 Acura MDX: four safety recalls, an open NHTSA AWD investigation, and phantom-braking complaints. Learn your California lemon-law rights.
You researched the 2022–2025 Acura MDX carefully. The fourth-generation YE1 promised a full redesign — a true luxury three-row SUV with a brand-new interior, a revised 3.5-liter V6, an optional Type S with a turbocharged 3.0-liter, and a 10-speed automatic that was supposed to elevate Acura into the upper tier of the segment. The badge said flagship. The technology said Premium. The price — often $60,000 to $80,000 out the door — said commitment. For many owners, the MDX has delivered exactly that. But for a meaningful subset, the YE1 generation has brought a pattern of problems that no luxury SUV buyer should have to navigate: an all-wheel-drive system that can suddenly revert to front-wheel drive on an icy highway after the transmission and transfer case splines shear without warning; a forward collision system that applies emergency braking with nothing ahead, throwing passengers forward at highway speed; a $15,000 drivetrain repair bill landing on an owner who is 10,000 miles past warranty. Consumer Reports rated the 2022 MDX as less reliable than other vehicles from the same model year, flagging in-car electronics, climate systems, and brakes as top problem areas. NHTSA received more than 25 powertrain complaints for the 2022 model alone — enough that a formal defect petition (DP26001) was filed in January 2026 and remains open as of mid-2026. Four separate safety recalls have been issued across the 2022–2025 model years, covering airbag sensors that can deploy unexpectedly, a rearview camera blackout that disables the federally required backup display, and a brake pedal pin that can shift the pedal out of position. If your MDX has been to the dealer repeatedly for any of these issues — and especially if you've seen multiple warning systems fail at once — this page is for you.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
backup camera blank; screen goes black in reverse; rearview camera distorted
brake pedal problem; reduced braking; unexpected braking; brake warning light
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
loud bang or clunk from underneath the vehicle while accelerating; all-wheel drive suddenly stops working, vehicle reverts to front-wheel drive only; loss of rear wheel traction with no warning lights; driveshaft spinning freely with no power transfer to rear wheels; transmission and transfer case grinding or slipping; AWD System Problem warning light illuminates; vehicle loses directional control on wet or icy roads
transmission jerks or lunges between gears at low speeds; harsh or abrupt downshift during deceleration; transmission hesitates or hunts between gears on the highway; vehicle surges forward as if shifting from 1st to 3rd instantly; delayed acceleration response when pressing the gas pedal; rough engagement pulling out of stop-and-go traffic; transmission whine or gear grinding sounds during shifts

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
Recall 24V064000 covers a cracking front-passenger weight sensor that can fail to suppress the airbag, directly affecting occupant protection in a crash. Honda issued a phased notification with three owner-notification tranches (March 2024, October 2024, August 2025), indicating completion challenges. Under Song-Beverly, a safety recall that cannot be completed — because parts are unavailable or the repair does not hold — counts toward the repair-attempt threshold. If your 2022 MDX has been to the dealer twice for this recall without a confirmed fix, that pattern may support a lemon-law claim.
Dealers will replace the seat weight sensors, free of charge. Owner notification letters were mailed March 28, 2024, October 18, 2024, and August 2025. This is a phased recall. Owners may contact Honda customer service at 1-888-234-2138. Honda's numbers for these recalls are XHP and VHQ.
backup camera blank; screen goes black in reverse; rearview camera distorted
Recall 25V032000 addresses a blank touchscreen that prevents the federally mandated rearview camera from displaying — a direct FMVSS 111 compliance issue. Because federal law requires functioning backup camera display, this is a per se safety defect. Any 2025 MDX that has experienced recurrent screen blackouts before or after the recall remedy may have grounds for a lemon-law claim if the repair does not permanently resolve the symptom.
Dealers will replace the center information display unit, free of charge. Owner notification letters were mailed March 3, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's number for this recall is RKZ.
brake pedal problem; reduced braking; unexpected braking; brake warning light
Recall 25V391000 involves an unsecured brake pedal pivot pin that can cause the pedal to shift out of position — in the extreme, this can result in a loss of braking ability. Brake failures are among the highest-severity defects under Song-Beverly. If a 2023–2025 MDX owner experienced a soft or displaced brake pedal before this recall was remedied, that event is directly relevant to a safety-defect lemon-law claim. Document every brake-related service visit and repair order.
Dealers will inspect and replace the brake pedal assembly as necessary, free of charge. Owner notification letters were mailed July 29, 2025. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are FLX and XLY.
airbag warning light; passenger airbag may not deploy; SRS warning; occupant detection fault
Recall 26V332000 expands the prior airbag sensor recall (24V064000) to cover 2022–2025 MDX vehicles and adds the risk of unintended airbag deployment — a consequence more severe than the original campaign. Owner notifications were not expected until July 2026, meaning many vehicles remain unrepaired. An owner whose MDX has already been in for the prior sensor recall and is now subject to this expanded campaign has documented evidence of a recurring safety defect, which strengthens a Song-Beverly claim based on multiple repair attempts for the same system.
Dealers will replace the seat weight sensors, free of charge. Owner notification letters are expected to be mailed July 6, 2026. Owners may contact Honda's customer service at 1-888-234-2138. Honda's numbers for this recall are BOL, WO9, OOA, WOM, XOH, NOC, POD, BOE, UOF, POB, EOG, AOI, QO8, TOJ, DO
loud bang or clunk from underneath the vehicle while accelerating; all-wheel drive suddenly stops working, vehicle reverts to front-wheel drive only; loss of rear wheel traction with no warning lights; driveshaft spinning freely with no power transfer to rear wheels; transmission and transfer case grinding or slipping; AWD System Problem warning light illuminates; vehicle loses directional control on wet or icy roads
An open NHTSA investigation (DP26001) covering 48+ complaints and active evaluation for a potential recall signals manufacturer awareness of a systemic defect. Under Song-Beverly (Cal. Civ. Code §1793.2), a safety-affecting powertrain defect that cannot be permanently repaired in a reasonable number of attempts — or requires a repair so extensive the vehicle is out of service for 30+ cumulative days — may trigger replacement or repurchase eligibility. Document every dealer visit, mileage, and any prior AWD warning light history.
Transmission and transfer case replacement (dealer quotes range from $10,000–$15,000 out of warranty). No recall or factory-authorized repair procedure confirmed as of Jun 29, 2026; NHTSA investigation DP26001 is open and evaluating whether a recall is warranted.
transmission jerks or lunges between gears at low speeds; harsh or abrupt downshift during deceleration; transmission hesitates or hunts between gears on the highway; vehicle surges forward as if shifting from 1st to 3rd instantly; delayed acceleration response when pressing the gas pedal; rough engagement pulling out of stop-and-go traffic; transmission whine or gear grinding sounds during shifts
A documented TSB (24-025) confirms Honda/Acura was aware of shift quality defects in the production calibration. Under Song-Beverly, if the dealer applies the software update and the harsh-shift symptom returns within a reasonable period, the repair is not 'conforming' and the attempt counts toward the repair-attempt threshold. Three or more unsuccessful repair attempts for the same defect — or 30+ cumulative days out of service — may qualify the vehicle for a repurchase or replacement.
TCM software recalibration per TSB 24-025. If harsh engagement persists after software update, valve body inspection and possible replacement. Some owners report improvement after software update; others report recurrence.
car slams on the brakes without any obstacle ahead; forward collision warning sounds and brakes apply hard at highway speed without obstruction; automatic emergency braking triggers in a parking lot with no vehicle present; adaptive cruise control disengages unexpectedly; passengers thrown forward by sudden hard braking; Low Speed Braking Control engages during slow turns with no object detected; CMBS (Collision Mitigation Braking System) warning light appears after false event
Phantom braking is a safety defect — sudden unintended deceleration at speed creates rear-end collision risk. If a dealer repeatedly recalibrates sensors without eliminating the false-activation symptom, each visit counts as a repair attempt. Under Song-Beverly, a safety defect that cannot be repaired in two attempts may qualify for expedited lemon-law relief. Owners should document every incident date, speed, road conditions, and any warning codes displayed.
Dealer camera/radar recalibration. Software update if available. Owners instructed to disable Low Speed Braking Control manually each ignition cycle as a workaround. No permanent fix confirmed; multiple owners report recurrence after dealer service.
infotainment screen goes black and then reboots while driving; touchpad controller is slow or unresponsive; navigation freezes and requires system restart; Apple CarPlay disconnects randomly and will not reconnect without restarting; wireless CarPlay drops connection repeatedly during a single trip; Bluetooth audio cuts out or fails to connect; screen remains grey or black when starting the vehicle; SiriusXM app cuts out without satellite loss
While infotainment defects alone are less likely to drive a lemon-law claim than safety defects, a screen that goes black disables the rearview camera backup display — a safety-adjacent failure. If infotainment failures occur alongside other covered defects, they strengthen the overall pattern of substantial impairment. Multiple repair visits for the same screen-freeze symptom count toward the Song-Beverly repair-attempt threshold.
Software/firmware update via dealer (OTA updates not widely available for this generation). Hard reset of infotainment system. In persistent cases, head unit replacement. Wireless CarPlay issues sometimes resolved by switching to wired CarPlay.
remote start via AcuraLink app does not work; app shows vehicle offline or cannot connect; remote lock/unlock fails through app; vehicle location does not update in AcuraLink; subscription-dependent features unavailable despite active subscription; charging pad overheats and loses wireless connection with phone
Connectivity failures that prevent marketed safety-adjacent features (e.g., remote start in extreme heat posing a comfort/health risk, or inability to locate a vehicle) can support a substantial-impairment argument when combined with other defects. Under Song-Beverly, any documented failure of a promised vehicle feature that persists through multiple repair attempts is relevant to the lemon-law calculus, even for non-safety systems.
Dealer TCU software update or module reset. In some cases, TCU replacement. Honda customer support escalation for subscription/server-side issues.
power tailgate opens and closes repeatedly on its own without input; tailgate stops mid-travel and reverses direction without obstruction; power liftgate will not open from key fob or interior button; tailgate responds erratically to kick sensor; liftgate motor makes grinding noise during operation
Intermittent power tailgate failure, while not a primary safety defect, represents a failure of an advertised feature. If the dealer repeatedly attempts repair without resolution, these visits accumulate toward the Song-Beverly repair-attempt count and can bolster a broader claim when combined with other documented defects in the same vehicle.
Dealer diagnosis of liftgate control module; software update or module replacement. Obstacle sensor inspection and cleaning.

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 (Cal. Civ. Code §1790 et seq.) may protect you if your 2022–2025 Acura MDX has a warranty-covered defect that Acura's authorized dealers have been unable to repair in a reasonable number of attempts.
YOU MAY QUALIFY if: (a) a safety defect — phantom braking, AWD loss at speed, airbag failures, or brake pedal defect — has required two or more repair attempts; (b) the same defect has required four or more attempts overall; or (c) the vehicle has been out of service for 30 or more cumulative days for warranty repairs.
FOR MDX OWNERS: The four active recalls — 24V064000, 26V332000 (airbag sensors), 25V032000 (rearview camera), and 25V391000 (brake pedal) — are warranty-covered defects. The phased notification schedule means some vehicles have returned for the same issue more than once; each visit counts. The open NHTSA investigation DP26001 into AWD spline failures involves a safety drivetrain defect; if your MDX failed during the warranty period, repair costs may be recoverable.
REMEDIES: A qualifying owner may be entitled to a replacement vehicle or a repurchase — refund of amounts paid minus a statutory mileage offset.

“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.
The MDX's worst defects — AWD spline failure and phantom braking — are intermittent, so dealers frequently write 'unable to duplicate.' Here is how to fight back:
1. DOCUMENT BEFORE YOU ARRIVE. Write down the exact date, mileage, speed, road conditions, and what you saw or felt. If a warning light appeared, note which ones and for how long. Submit this in writing to the service advisor so it is on the repair order.
2. DEMAND VERBATIM SYMPTOM ENTRY. Ask the service advisor to write your words on the repair order — not 'customer states vibration' but 'transmission jerks from 1st to 3rd gear at 25 mph during low-speed acceleration.' Vague entries are hard to track across visits.
3. CITE NHTSA PETITION DP26001 FOR AWD LOSS. If your MDX is losing all-wheel drive, ask the service manager whether NHTSA investigation DP26001 (January 2026, transmission-to-PTO spline failures in 2022–2023 MDX) has been reviewed. A dealer aware of an open NHTSA investigation cannot credibly claim the issue is unknown to the manufacturer.
4. REQUEST TSB 24-025 FOR HARSH SHIFTS. Ask service to apply Honda/Acura Service Bulletin 24-025 (10-speed TCM calibration). If they decline, document the refusal in writing.
5. KEEP EVERY REPAIR ORDER. A 'cannot duplicate' return still counts as a repair attempt under Song-Beverly if your complaint was documented. Get a copy before you leave.
6. COUNT YOUR DAYS OUT OF SERVICE. Thirty or more cumulative days with the dealer for warranty repairs is an independent lemon-law trigger — regardless of repair-attempt count.
The 2022–2025 Acura MDX YE1 is a capable luxury SUV burdened by defects Honda/Acura has been slow to address. The AWD spline failure is the most alarming: a structural drivetrain defect costing owners $10,000–$15,000 out of pocket, still awaiting an NHTSA recall determination as of mid-2026. Phantom-braking complaints span all four model years with multiple dealer visits resolving nothing — a pattern that independently supports a lemon-law claim in California. Four safety recalls confirm Honda was aware of safety-critical defects across the entire production run. Owners who have been to the dealer three, four, or five times deserve a clear answer about their rights. The recalls are documented, the NHTSA investigation is open, and California law was written for exactly this situation.
— The Margarian Law team
If your 2022–2025 Acura MDX has been to the dealer multiple times for AWD failure, phantom braking, airbag recalls, brake pedal problems, or infotainment defects, you may have options under California's lemon law. Margarian Law has handled thousands of lemon-law cases and offers a free, no-obligation case review. Call or submit your information online — there is no cost unless you recover.
The 2022–2023 MDX has a documented pattern of transmission-to-transfer-case spline failures that instantly cut power to the rear wheels, reverting the vehicle to front-wheel drive. NHTSA defect petition DP26001 (filed January 2026) is evaluating 48+ complaints for a potential recall. No recall has been issued as of June 2026.
Yes. NHTSA issued recall 24V064000 in 2024 for the front-passenger airbag weight sensor, which can crack and fail to suppress the airbag in a crash. A second, expanded recall (26V332000) was issued in May 2026, adding the risk of unintended airbag deployment. Owner notifications were expected by July 2026. Contact your dealer or search your VIN at NHTSA.gov to confirm if your MDX is affected.
Multiple 2022–2024 MDX owners have filed NHTSA complaints describing the AcuraWatch forward collision avoidance system applying emergency braking with no vehicle or obstacle ahead — sometimes at highway speed, sometimes in parking lots. This phantom-braking pattern has recurred after camera recalibration at the dealer, with no fault codes stored. No recall has been issued as of June 2026.
Consumer Reports rated the 2022 MDX as less reliable than other vehicles from the same model year, citing in-car electronics, climate system, and brakes as top problem areas. NHTSA records show over 100 complaints for the 2022 model year alone, spanning AWD failure, ADAS false activations, electrical issues, and four active safety recalls. Long-term reliability improves in later model years but issues persist across the 2022–2025 generation.
Ask the service advisor to document your exact symptom description on the repair order, not a vague summary. Request that TSB 24-025 (10-speed TCM calibration) be applied if you have harsh-shift complaints. If the AWD drops out, mention NHTSA petition DP26001. Keep every repair order — California lemon law counts a 'cannot duplicate' visit as a repair attempt if your complaint was recorded.
You may qualify for a replacement vehicle or refund under California's Song-Beverly Act if your MDX has a warranty-covered defect that Acura has failed to repair after a reasonable number of attempts, or if your vehicle has been out of service for 30 or more cumulative days. Safety defects — such as the airbag recalls, brake pedal recall, AWD failure, or phantom braking — typically require fewer repair attempts to trigger eligibility. A free case review can assess whether your specific repair history qualifies.
