255 reports, newest first.

  1. Engine and engine cooling, May 4, 2026

    The contact owns a 2017 Acura MDX. The contact stated that while driving at 40 MPH the engine seized. All the warning lights illuminated. The contact stated that the failure was due to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The vehicle was towed to an independent mechanic who determined there was an internal engine failure. The local dealer was contacted, where it was diagnosed that there was rod bearing and engine failure. The vehicle was not repaired. The manufacturer was contacted and opened a case. The claim was denied. The failure mileage was approximately 122,220.

  2. Forward collision avoidance, Lane departure, Apr 25, 2026

    The multipurpose front camera on my 2017 Acura MDX failed with DTC U3000‑49, disabling LKAS, ACC, CMBS, and FCW. Acura issued Service Bulletin 23‑008 acknowledging a software defect, but my VIN was denied eligibility despite matching the bulletin’s criteria. This is a safety‑critical failure affecting many owners, and Acura is forcing consumers to pay for camera replacement instead of providing the software fix. My 2017 Acura MDX (VIN [XXX] ) is experiencing a failure of the multipurpose front camera, which controls several collision‑avoidance systems including: Lane Keeping Assist System (LKAS) Adaptive Cruise Control (ACC) Collision Mitigation Braking System (CMBS) Forward Collision Warning (FCW) All of these systems became disabled, and the vehicle displays multiple warning lights. The diagnostic code stored is U3000‑49 (FCW/LDW Camera Unit Malfunction). Acura issued Service Bulletin 23‑008, which states that: “A problem exists with the detection logic in the multipurpose camera software.” The bulletin applies to all 2017–2018 Acura MDX trims, and the corrective action is a software update to the camera module. My vehicle matches the exact symptoms described in the bulletin. However, Acura and the dealership informed me that my VIN is “not eligible” for the update, even though the bulletin explicitly lists my model year and trim. Instead, I was told I must pay for a full camera replacement, costing over $1,200, despite Acura acknowledging the issue is software‑related. This leaves me with a disabled safety system and no manufacturer‑supported remedy. The failure is widespread among 2017 MDX owners, and many report identical symptoms and identical denials of coverage. Because this defect disables multiple federally relevant safety systems simultaneously, I believe this should be treated as a safety recall, not a customer‑paid repair. I am requesting that NHTSA investigate this issue and require Acura to provide the software update.Thank you.

  3. Electrical system, Engine, Apr 21, 2026

    The main issue is engine knocking and ticking also winding noise. There has been an issue with electrical with rear passengers getting burnt due to heat coming out of rear when rear system is off.

  4. Engine, Apr 17, 2026

    A rod bearing inside the engine failed and created metal shavings inside the engine. The vehicle has not been fixed yet, so it is available for inspection currently, but I will be having the engine replaced in the next 2 weeks. With the metal shavings inside the engine it could cause a catastrophic failure of the engine while driving at any point The dealer has inspected and diagnose it as a rod bearing failure I reached out to Acura customer service to make them aware and ask for assistance in reviewing for coverage in the ongoing recall, but since my vehicle was not manufactured in the plant covered under the recall, they are unable to help. I asked for a good will credit and after they conferred with the dealer they stated the failure was not due to a manufacturing defect, therefore they cannot help. There were no warning lamps or messages from the vehicle. The only symptom was a ticking sound, that got louder at higher RPMs, coming from the front of the engine on the passenger side. I’ll also add that based on CARFAX report and our service records since we bought the vehicle, all recommended maintenance has been performed as recommended by the manufacturer.

  5. Vehicle speed control, Other or unspecified, Forward collision avoidance, Apr 4, 2026

    My 2017 Acura MDX unexpectedly shifts into neutral while I am driving, specifically when slowing down approaching stop signs. When this happens, the vehicle loses power and will not accelerate, creating a dangerous situation in traffic. I have to manually press the Drive button to put the vehicle back into gear while still on the road. This has happened multiple times without warning and no recall exists for this issue. This is a serious safety hazard because the vehicle can lose power in traffic or intersections.

  6. Engine, Apr 2, 2026

    My vehicles motor is internally destroying itself. The rod bearing has gone and the motor is none functional. The car only has 98k miles. I have gotten the oil changed every 3k-4k miles and used 0W-20 oil as the manufacturer desired. It seems as though there has been 1.4million cars with this same issue as mine. I think a recall is in order. OEM new motor is $25.7k.

  7. Fuel/propulsion system, Apr 1, 2026

    When I have already started to go in motion, for example when turning left, and I let go of the gas pedal and then press the gas again once I decide its safe to turn, my car doesn't respond to the gas for about a couple of seconds. This has also happened when I am driving on the highway and I am already in motion and I want to go faster to pass another vehicle, my car hesitates for a couple of seconds before it responds to me pushing the gas pedal.

  8. Forward collision avoidance, Lane departure, Mar 29, 2026

    I am reporting a major safety failure on my 2017 Acura MDX regarding the forward-facing multipurpose camera. Out of nowhere, the camera failed and triggered a cascade of warning lights across my entire dashboard. Because of this hardware defect, all of the critical safety systems—including the Collision Mitigation Braking System (CMBS), Lane Keeping Assist (LKAS), and Adaptive Cruise Control—are now completely disabled. Having these emergency systems shut down while driving in traffic is a serious safety hazard. Furthermore, the constant flashing of 5 or 6 different warning lights on the dash is a massive distraction while trying to operate the vehicle. This is a well-documented hardware failure in these models, and it shouldn't be left to the owners to pay thousands of dollars to fix a primary safety component that failed prematurely. This needs to be investigated as a mandatory safety recall before these failures lead to an accident.

  9. Fuel/propulsion system, Mar 21, 2026

    I noticed a whirring sound while driving my MDX. The repair shop investigated and noted that the bearing in my transfer case assembly is failing and needs immediate replacement to prevent total power loss to the propulsion system of the car. Current milage of the vehicle is 99,500.

  10. Electrical system, Air bags, Other or unspecified, Mar 18, 2026, crash

    On 11.25.25, my MDX was involved in a multi-car hit and run on highway 101 SB at the Laurel Drive off ramp. The vehicle sustained two points of impact: (1) substantial front/driver side impact (2) rear-passenger side impact. Despite the severity, location of impact and speed of travel at the time of the collision, all airbags deployed except for the driver side curtain airbag. Importantly, at the time of the crash, the Lane Keeping Assist System (LKAS) and associated AcuraWatch driver assist systems were activated. The vehicle’s safety assistance technology was engaged and functioning immediately prior to impact. Considering the above mentioned facts, driver side airbag failing to deploy, raises serious concerns regarding Possible software or signal-processing malfunction or electronic communication between radar/camera systems and the SRS module. The nature and severity of the impact clearly met deployment criteria for the driver side airbag. This failure raises concern that there may be a defect in the SRS system, including but not limited to: Airbag inflator component or propellant issue. Supplemental Restraint System (SRS) crash sensor calibration. SRS control module deployment logic. Crash signal sensors. Event-trigger logic or interconnnect failure. Wiring harness or inflator defect. Whether the system registered steering correction or impact prediction, the failure to deploy increased my risk and resulting injury, as well as compromised the fundamental safety system designed to protect drivers in front-impact crashes.

  13. Engine, Feb 12, 2026

    One or more connecting rod bearings are failing. There is a knocking noise coming from the lower end of the engine which is more pronounced under load. There is a risk of the engine failing completely while driving and causing risk to myself, my passengers, and other drivers. This issue is know to happen in the same engine (J35Y5) and certain VINs are already under recall.

  14. Power train, Vehicle speed control, Feb 8, 2026

    There were several instances where my vehicle either accelerated or decelerated while I was driving. I first noticed the issue about a week after I purchased the car in May 2022. I took it back to Acura of Brookfield, and they said they couldn’t replicate the issue. I also took my car to Acura of Brookfield in September 2023 for the same jerking issue. They charged me for an update, but the issue did not change. I continued noticing the problem over the years, but it happened more frequently in 2025. In May 2025, I was driving down a hill in Brookfield, Wisconsin, when my car jerked aggressively and then accelerated on its own. Throughout the rest of the year, it would either accelerate or decelerate while I was on the highway. On January 20, while I was on my way to the gym, my car jerked and decelerated while I was on the highway. I was able to pick up speed again and continue driving to the gym. When I came back out, my car started, but it would not shift out of park. I had the car towed to Acura of Brookfield, and they said something about the hydraulics inside the transmission being bad, and that they had to replace the entire transmission.

    Hello, I am writing to report that my 2017 vehicle is experiencing the same issue that was subject to a recall on the 2016 models. Despite the recall being associated with the 2016 year, my 2017 vehicle is showing identical symptoms and concerns. This raises serious questions about safety, reliability, and whether this issue extends beyond the originally recalled model year. I would like this concern formally documented and request a review of my vehicle to determine whether it qualifies for repair, inspection, or coverage related to the prior recall. Please advise on the next steps and whether this issue has been reported or addressed for 2017 models. Vehicle details: Year: 2017 I appreciate your prompt attention to this matter and look forward to your response. Sincerely, [XXX] If I get killed me or my [XXX] son, you all will be responsible. You made these faulty vehicles. [XXX] I'm have to get a lawyer involved if issues are not addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    Since 2020 the transmission does not shift properly from second to third gear. The power drops and the car shutters and makes noise like gear teeth are missing. This does not happen every time though. Sometimes multiple days will pass before the problem arises again. There have been a couple of times where I barely avoided a wreck because of the drop in power and underperformance of the transmission.

    Our 2017 Acura MDX has developed a crank rod bearing knock. Fox Acura in Grand Rapids, Michigan, has advised that our vehicle’s VIN is not included in service bulletin 23 036 concerning connecting rod bearing failure, despite evidence that similar failures have occurred in Acura 3.5 liter engines outside the bulletin’s listed VIN range. I intend to submit a safety complaint to the NTSB regarding this issue. Fox Acura has recommended a full engine replacement. I respectfully request that Acura expand the scope of the service bulletin to include our vehicle and provide coverage for the recommended repair.

  18. Engine, Jan 9, 2026

    On my way home from work one evening, the car started making a loud knocking noise, then the car started losing power, the rpms jumping up and down and the dashboard lit up with warnings of all kinds. The traffic was somewhat heavy and and cars were speeding pass me, brakes screeching, horns blowing and my car steadily losing power. I was afraid, I didn't know what to do. I was trying to find a safe place to pull off the road. It was a traumatic experience as a large truck swerved into the other lane of traffic to avoid hitting me, almost causing an accident. Luckily I made it home safely. I had a mechanic look at it the next day and he said the engine needed to be replaced. Not convinced of the diagnosis, I had the car towed to another mechanic who confirmed the engine would have to be replaced. I had no issues with the car or the mechanics of the car prior to this. I could not for the life of me understand how my 2017 Acura MDX with only 74,000 miles on it, could possibly need a new engine unless it was defective. So I then towed the car to the Acura dealership where they confirmed, the engine needed to be replaced. However, when I asked about the engine recall, I was told my VIN is not included in the recall although it is the same exact issue. Acura did offer a one time goodwill assistance for 25% of the repair costs if performed at Acura. Admission of guilt knowing my car has a defective engine is what that says to me about Acura's offer of 25%! Since the car was useless without a engine, I have since had it repaired by an independent mechanic. I'm very disappointed in Acura.

    Dear Acura, My MDX is showing many lights on the dashboard (LKAS, ACC, Break System, CMBS, RDM) associates with the code U3000-49 and all those features are deactivated due to the failure mentioned. I was searching on the website for this error and found many Acura MDX oweners experiencing the same issue which apparently the Windshield Lane Departure Camera. Honestly, Acura should take a look into this since this issue is getting worse and those are safety features on the vehicle. Regards,

    Engine completely seized due to connecting rod bearing failure. This happened while driving, and I was stuck in traffic for almost an hour due to the vehicle being inoperable. vehicle was unable to be put in neutral due to a special tool being needed. Technicians from a third-party shop and Acura dealership stated this part does not break very often. The Vin does not fall in the parameters for the recall. The issue started the day prior with the engine, sounding like it needed a tuneup. After conducting the tuneup, the engine seized 20 miles after. The engine had to be completely replaced at the owners expense. Accurate did cover 50% of the replacement engine.

  22. Engine, Dec 17, 2025

    My 2017 Acura MDX has an engine failure due to connecting rod bearing seizure in the 3.5L V6 engine. Recall 23V-751 covered model year 2016-2020 Acura MDX vehicles and mine is a 2017. But, my VIN is not in Honda's recall range. The ODI had apparently received 414 reports of connecting rod bearing failures in the 3.5L V6 engine that are outside of 23V-751. There is now an ODI Resume with number PE25008. See the two linked PDF documents below. [XXX] [XXX] The Acura dealer said that this is definitely the same problem they have seen on vehicles under the recall range. In their computer system where it says "Cause" they wrote "Cylinder 6 spun causing the knocking noise. excessive material in oil pan. if under the rod recall, it would need a long block." I have a screenshot of this if you would like it. My service representative at the dealership texted me the following "The engineer from Acura was here today and our District Manager - the engineer said they will not be expanding the recall on the Acura side. Just thought I'd let you know." I have this text message if you would like a screenshot of it. So, it sounds like Acura will not voluntarily expand the recall. This is going to cost me about $12K to fix. Is the NHTSA ODI investigation still ongoing? When will I know if the VIN range will be expanded as I would like to get reimbursed by Acura for these repairs.
