  While preparing to enter the expressway my 2018 MDX stalled and various dashboard lights came on. My family and I drifted into the median while nearly being hit by passing car. It took about 10 minutes before the MDX became operational again. I took it to a local mechanic when we arrived at our destination. They couldn't locate any issues or "bad codes." Since that incident my fuel mileage and shifting has begun to deteriorate. Entering traffic and trying to pass cars has become difficult while driving. I have called Acura and a local dealership in Charlotte, NC. Both failed to provide next steps that didn't involve spending money to fix an issue that based on feedback on various sites and NTSB site is a common issue.

OBJECTS ALSO QUICKLY MAGNIFY AND THEN REVERT TO NORMAL SIZE CAUSING BLURRYINESS AS WELL AS AFFECTING THE ABILITY TO DETERMINE ACCURACY OF OBJECT PLACEMENT AROUND YOU WHEN DRIVING. THE WINDSHIELD IS A DANGEROUS SAFETY HAZARD PUTTING DRIVERS AT RISK FOR ACCIDENTS. AFTER JUST DRIVING IT JUST A FEW MILES, I BEGAN TO NOTICE DIZZINESS AND RESULTING NAUSEA FROM OBJECT DISTORTIONS.

BUT FOR SAFETY REASONS IT IS IMPOSSIBLE TO NEGLECT A LARGE PORTION OF THE VISUAL FIELD WHEN OPERATING MOTOR VEHICLE.

• 12/07/2025· VEHICLE SPEED CONTROL

  When trying to accelerate from a stop the car has a noticeable lag in throttle response. 2+ seconds. This does not always happen but is intermittent. Much more often when the engine is colder. This makes a left turn in front of traffic or any move where you need to merge with traffic go from safe to dangerous, this also confuses other drivers as they wonder why you are not moving. Someone who was unfamiliar with my car ended up in the middle of an intersection blocking because they didn’t accelerate. Looking into the problem it seems to be reported quite often and is “normal”. Honda does not see this as a problem and anyone who has “fixed” the problem has used aftermarket parts. The car does not have auto engine stop/start so the car is always running.

  Honda refuses to inspect my vehicle to determine if it is safe to drive. They say they will not inspect vehicles untill they have the repair parts available. That puts me at risk for driving a defective vehicle and having an accident that could cause property damage and/or death for me and other people. As I do not have the technical expertise to inspect the vehicle myself, I have no choice but to park it until Honda decides to act. I belive that this is unreasonable and constitutes a failure to act timely. They should at least be willing to do the inspection now to determine if the vehicle is safe or not and then do any necessary repairs once the parts are available. They will need to inspect the vehicle eventually anyway, so I am not asking them to do anything extra.

A minute later the car stopped and would not start and started to have smoke and flames come from under hood and through inside windshield and dash. My daughter was able to get out and take her 3 year old son out of his carseat and run for their lives as the car completely became engulfed in flames.Thank God they made it out alive. Police and Fire department showed up. Car was a total loss, everything was burnt. One day the Acura MDX fires will take someone's life. Called Hoehn Acura in Carlsbad Ca and sent service manager Skip about 12 pictures of the completely burnt vehicle. He never returned my calls after leaving several messages. Also left message with general manager and no return call. They don’t care. They only appear interested when you are buying the vehicle. I did file a claim with Acura corporate office and still no word from them either. I have read many cases about the MDX going up in flames for no reason, even in the driveway or drive in your neighborhood. Not sure why they have not recalled this or tried to solve the issue. I am asking for someone to look into this as this is not an isolated incident before lives are lost. Once I get police report I will also send you pictures as well. Thank you.

  When at a complete stop at a stop light or stop sign and ready to press the gas to accelerate, there’s a delay for the car to even start moving. It doesn’t want to go when pressed on. Which can cause the person behind me to hit the back of the car. It nearly came to that. There’s sudden fast movement when accelerating to get the car to move forward. It’s been happening numerous times where the gas pedal isn’t recognizing the acceleration part. I’ve read plenty forums about this issue with this vehicle and still not enough complaints for a recall? Can we look into this as this is a safety issue. The car won’t accelerate when you want it to.

• 11/11/2025· VEHICLE SPEED CONTROL

  When you press the accelerator pedal there is a significant delay in the pedal response particularly at low speed. As you press accelerator pedal nothing happens for a second or two. Then the vehicles accelerates not a gradual rate but at the rate of where the accelerator pedal is at when the vehicle begins to speed up. This causes sudden and hard acceleration. This delay and or sudden acceleration is dangerous when trying to pull into traffic. The Vehicle is available for inspection upon request. Was brought to dealer and after a very short inspection, was told nothing was wrong. They did do a transmission software update. This did not change anything. This is an issue reported in on-long blogs frequently. No warning lamps to error codes related to this issue according to the dealer. This has been an ongoing issue for as long I have owned the vehicle but gets worse as the vehicle gets older.

  I submit this complaint because my 2018 Acura MDX, covered under NHTSA recall 23V-751 for connecting-rod bearing defects, has suffered progressive engine damage and final engine failure that I believe was caused by the manufacturer’s recalled defect and by the dealer/manufacturer’s failure to timely perform the recall repair. Timeline & key facts: 2024: Vehicle displayed code P0159 (O₂ sensor slow response). I contacted Acura corporate and opened a case. The O₂ sensor was replaced under warranty. I continued to report reduced acceleration and intermittent check-engine illumination to the dealer and to Acura corporate. I repeatedly requested that the recall inspection/repair be performed, but the repair was delayed or not scheduled despite the vehicle’s symptoms and my repeated follow-ups.2024–2025: Over the following months I repeatedly requested recall service and documented those requests with the dealer and Acura corporate. On many occasions I was not scheduled for the recall or was told to wait for parts/authorization. I was also treated rudely by dealership staff (identified service advisor: Tara at Acura on Chapman Road), and my case was not escalated appropriately despite my persistence. 2025: Vehicle later displayed P0430 (catalyst efficiency below threshold, Bank 2), and within [insert timeframe] the engine experienced complete failure requiring immobilization. Dealer notes show an oil-pump leak and catalytic converter symptoms consistent with oil/fuel contamination and bearing-related engine issues. I have service records documenting the sensor replacement, subsequent dx, and the dealer’s findings. Effect: I have been wi/o a vehicle since the engine failure, incurred hotel cancellation charges $116 and other consequential damages. I believe the engine damage was preventable and is directly tied to the acknowledged defect in the recall; the catalyst and O₂ sensor failures were downstream consequences of recall-related engine problems (oil consumption,

  I am filing this report regarding my 2018 Acura MDX that has experienced complete engine failure directly related to the Connecting-Rod Bearing Safety Recall (NHTSA Recall 23V-751) and Acura’s failure to perform the recall when I first reported issues. In 2024, my vehicle began showing engine trouble codes (P0159) and experienced reduced acceleration and check engine light warnings. I contacted Acura corporate and opened a case, explaining that the vehicle was exhibiting symptoms similar to those described in the recall, including engine hesitation and performance issues. I also took the vehicle to Acura of Chattanooga on Chapman Road, where I worked with Tara, a service advisor who acknowledged remembering my repeated attempts to get the recall addressed. Despite this, the recall repair was never performed, and I was treated rudely and dismissed each time. Over the past two years, I have made multiple documented attempts to have the recall completed. Each time, Acura failed to take action or stated that parts or authorization were unavailable. In 2025, my vehicle displayed Code P0430 (Catalyst Efficiency Below Threshold, Bank 2) and ultimately suffered complete engine failure. The issues with oil circulation, catalytic converter performance, and acceleration are consistent with the rod bearing defect Acura has acknowledged as part of this recall. Recently, Acura informed me that my recall was “completed,” even though the engine is now inoperable. This is unacceptable, as the recall was meant to prevent this exact type of engine damage, and Acura had two years of opportunity to address the issue before failure occurred. The current situation has left me with a non-functioning engine, significant repair costs, and a serious safety concern that could have been prevented if Acura had honored its recall responsibilities in a timely manner. I am requesting that NHTSA investigate Acura’s handling of this recall and their pattern of delaying or denying recall repairs

A new battery was bought and put in by myself on October 4, 2022, since I did not realize that the battery was still under warranty. Everything looked normal on October 5, 2022. But in the morning of October 6, 2022, the headlights were found to be on even though nobody was around the car parked in the garage. Sometimes the alarm would go off. This happens randomly but frequently ever since. An appointment was made with the dealer, and the car was checked out on October 10, 2022. The dealer determined that the Keyless Module Unit was faulty, but the part was on back order. The service advisor assured me that it should be safe to drive the car. Ever since, the car has been trying to start itself frequently and randomly. It would turn on the headlights, move the driver seat, go through the engine turnover cycle, etc. Sometimes it also moved the window shield wipers, or sounded the alarm even though the car was not locked. Being afraid of driving the car, I started to ask for a loaner or rental car from the the dealer on October 12, 2022, and have been talking to both Acura warranty department and the dealership since. Today (October 24, 2022) the car would not start, and had been towed to the dealership.

  While operating the vehicle, multiple driver-assist warning indicators illuminated on the dashboard, including LKAS (Lane Keeping Assist System), ACC (Adaptive Cruise Control), and CMBS (Collision Mitigation Braking System). The systems either disengaged or functioned erratically during normal driving conditions. At times, the vehicle failed to maintain lane position, abruptly disengaged adaptive cruise control, or displayed collision alerts when no obstruction was present. Now it is constant. Safety Impact: The failure of the LKAS, ACC, and related systems can cause unexpected loss of vehicle assist functions, leading to abrupt speed changes or compromised lane control, increasing the risk of collision if not promptly corrected.
