Most common Acura warranty defects
Recent Acura repeat-repair complaints concentrate in engine-management software on the turbocharged Type S V6 and the 2.0L turbo four, steering assist on the RDX and Integra, brake-pedal and stability-system hardware on the TLX and MDX, and the short-lived, GM-built ZDX electric SUV. Many of these fixes are software reprograms or recall campaigns, so your service history with Acura often shows exactly when the problem was first reported — which is the starting point for any lemon law claim.
MDX Type S and TLX Type S stalling and loss of power
Recall 25V-031 covers about 295,000 vehicles, including 2021–2025 TLX Type S and 2022–2025 MDX Type S models (along with Honda’s Pilot). According to the recall filing, a software error in the fuel injection control unit can cause the engine to stall or lose power, and the remedy is a reprogram of that unit. Because the fix is software, the key question afterward is whether the stall or power loss ever happens again; if it does, the Type S fuel-injection recall becomes the first of several documented repair attempts. A separate small recall (24V-950) replaced fuel tanks on certain 2021–2023 TLX sedans whose filler necks were improperly welded and could leak.

RDX and TLX 2.0L turbo misfires and rich-fuel codes
Acura service bulletin 23-010, revised in March 2024, applies to all 2019–2023 RDX models and 2021–2023 TLX models other than the Type S. It describes drivability complaints with random or single-cylinder misfire codes (P0300–P0304) or a “fuel system too rich” code (P0172), most common in cold weather. Acura attributes it to a calculation error in the engine computer during cold starts. The prescribed repair is an oil change, a fuel-injection software update and relearn procedures — not a hardware replacement. If your check-engine light, rough idle or hesitation returns each winter after that update, keep the codes and repair orders; a recurring misfire under warranty is the kind of pattern a claim is built on.

RDX, Integra and Integra Type S steering assist faults
Acura’s steering problems span hardware and software. Recall 25V-582 reprograms the electric power steering on about 17,000 2025 RDX models because miscalibrated software can put the system into a failsafe mode and cut steering assist. Recall 24V-114 replaced the steering rack on certain 2024 RDX models after an improperly tightened gearbox let water in, corroding and binding the gears. Certain 2023–2025 Integra and 2024–2025 Integra Type S models are included in the same gearbox recall as the Civic (24V-744), which addresses excessive internal friction that makes steering difficult. Either way, the driver feels the same thing: steering that suddenly takes much more effort. If the RDX power steering recall or the Integra gearbox repair does not hold, that is a recurring safety defect.

TLX and MDX brake pedal and stability-system recalls
Recall 25V-391 covers 2021–2025 TLX and 2023–2025 MDX models (plus the Honda Pilot) whose brake pedal pivot pin was not secured properly; the pedal can shift out of position and keep the driver from braking as intended. Dealers inspect and replace the pedal assembly as needed. On certain 2023 RDX and Integra models, recall 23V-430 replaced the vehicle stability assist modulator because a ball valve could leak brake fluid, which can cause unintended vehicle movement while Brake Hold is engaged or unexpectedly longer brake pedal travel. Brake complaints carry weight in lemon law because they directly affect safety, and many states require fewer repair attempts for defects that can cause serious injury.

MDX center display, camera and air bag sensor faults
The fourth-generation MDX has had electronics recalls of its own. Under recall 25V-032, the center touchscreen in certain 2025 MDX models can go blank, taking the rearview camera image with it; dealers replace the center information display. A broader 2026 recall (26V-332) replaces front passenger seat weight sensors that can crack and short circuit, affecting 2022–2026 MDX, 2019–2024 RDX and certain TLX models alongside many Hondas; see our seat sensor air bag recall overview. Blank screens, frozen cameras and air bag warning lights are intermittent by nature, so photos or short videos taken when they occur make it far harder for a service department to write “no problem found.”

ZDX electric SUV brake, suspension and display recalls
The 2024 ZDX was built by General Motors in Spring Hill, Tennessee, and Honda confirmed in September 2025 that ZDX production had ended. Its short run produced several recalls: an over-the-air or dealer update for AWD models whose anti-lock brakes could activate unexpectedly and release brake pressure (24V-614); front stabilizer bar bracket bolts that could loosen and damage high-voltage cables or battery coolant lines (25V-018 and 25V-234, the first covered in our ZDX electrical system recall article); a software fix for a failing instrument display and blank rearview camera (26V-112); and a camera replacement (26V-306) whose remedy was not expected until late 2026. Discontinued, low-volume EVs can mean longer waits for parts and technicians.

Signs your Acura may be a lemon
- Repeated Type S power loss. Your MDX Type S or TLX Type S stalled or went into reduced power again after the fuel-injection software recall.
- Misfire codes every cold season. Your RDX or TLX keeps returning with P0300-series or P0172 codes despite the bulletin’s software update.
- Steering assist that cuts out. Your RDX or Integra steering suddenly turns heavy, and the problem has outlasted a reprogram or gearbox repair.
- A blank center screen. Your MDX’s touchscreen or rearview camera keeps going dark, and the dealer cannot make it fail on demand.
- A ZDX stuck at the dealer. Your ZDX has spent weeks waiting for parts, software or an available EV technician.

What Acura’s warranty means for a claim
Acura’s coverage is longer than Honda’s. The 2026 Acura warranty booklet lists a New Vehicle Limited Warranty of 4 years or 50,000 miles (including the 12-volt battery), Powertrain coverage of 6 years or 70,000 miles, Rust Perforation coverage of 5 years with no mileage limit, and seat belt coverage of 15 years or 150,000 miles. That extra year and those extra miles matter: a defect that first appears in year four on an RDX or MDX may still fall within the basic warranty, and engine, transmission and drivetrain defects remain covered into year six.
Acura dealers typically address engine-management, steering and display complaints with software updates, and intermittent faults are often closed as “could not duplicate.” Ask that every repair order list your complaint as you described it, any stored codes, and the dates in and out. Acura’s 2025 and 2026 booklets also contain an agreement to arbitrate disputes, with a 30-day opt-out window after delivery, and describe an optional program run by the National Center for Dispute Settlement. Keep your booklet and any opt-out letter.
Acura recalls and problem reports
No Acura articles match that exact combination — but that does not mean you do not have a claim. Repeat repair attempts, days out of service, and warranty status matter more than whether a recall exists.
A recall is not a claim
An open recall on your Acura is not, by itself, a lemon law case — and a recall that has already been repaired does not mean you don’t have one. Recalls are safety campaigns run by the manufacturer; lemon law claims turn on how your specific vehicle has performed under warranty. What matters is the record: how many times you brought the vehicle in for the same problem, how many days it has spent out of service, and whether the defect substantially impairs its use, value, or safety while covered by the manufacturer’s warranty.
An Acura that has been back to the dealer repeatedly for one persistent issue can qualify with no recall on file, while a vehicle with three open recalls may not qualify at all if each was repaired on the first visit. Repair-attempt and days-out-of-service thresholds vary from state to state, so the same facts can play out differently depending on where you bought or registered the vehicle. Keep every repair order — the paper trail is the case.

Jason S. HegedusManaging Partner & FounderFrequently asked questions about Acura lemon law claims
My MDX Type S stalled after the recall update. Does the recall visit count?
It can. The 25V-031 reprogram is a warranty repair for a defect that can stall the engine or cut power, and it is logged under your VIN. If the stall or loss of power returns, every later visit for the same symptom builds on that first attempt. Note where and how it happened, any messages on the dash, and whether the car restarted, and make sure the service advisor records those details rather than a generic “check engine light” entry.
My RDX throws misfire codes every winter. Could that be a lemon?
Possibly. Acura’s own bulletin 23-010 recognizes cold-start misfire and rich-fuel codes on 2019–2023 RDX models and prescribes a software update. If the update was performed and the codes, rough running or flashing check-engine light keep coming back, those repeat visits for the same engine defect can support a claim while the vehicle remains within warranty. Ask the dealer to print the stored codes on each repair order.
Does Acura’s longer warranty help my claim?
It can widen the window. Acura’s basic coverage runs 4 years or 50,000 miles and powertrain coverage runs 6 years or 70,000 miles, compared with 3 years/36,000 and 5 years/60,000 on a Honda. State lemon laws set their own time and mileage limits, which are often shorter than the warranty, but warranty coverage still matters for repairs and for other warranty claims. Check both dates against your first repair visit.
The ZDX has been discontinued. Does that affect my rights?
Acura’s warranty obligations on your ZDX continue after production ends. What changes in practice is how quickly parts, software fixes and trained technicians are available, and several ZDX recalls have depended on updates or parts that arrived later. Many state lemon laws count total days out of service, so ask for dated repair orders showing when your ZDX arrived, what was on order and when it was returned.
Is the Integra affected by the same steering recall as the Civic?
Yes. Recall 24V-744 covers certain 2023–2025 Integra and 2024–2025 Integra Type S models along with Civics and other Hondas. The remedy is a replacement worm-gear spring and grease. If your Integra’s steering still feels stiff or catches after that repair, report it again promptly and in writing so the repeat attempt is documented.
Do I have to use Acura’s dispute program or arbitration before filing a claim?
Not necessarily, but the paperwork matters. Acura’s booklet says it does not require you to use the National Center for Dispute Settlement before litigation, though some states may require a dispute program first. The same booklet contains an arbitration agreement unless you opted out within 30 days of delivery. How those provisions apply depends on your state and your vehicle, so have them reviewed before filing.
Think your Acura might be a lemon?
