I want to say that the engine or transmission is faulty. Sometimes while at a complete stop, the car will not advance and tries to stall or lose power. It takes about 2 or 3 seconds to finally go after I push the accelerator pedal almost 3/4 throttle. No it has not been reproduced at the dealer. I took it May of 2024 for the engine recall repair. They said that the repairs should fix the problem but it has maybe even worsened. No warning lamps appear when the problems happen.

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.

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.

This is a complaint about the defective TPMS components in this vehicle. I sent a copy to Acura and Honda Client Relations and to the Dealer (Montano Acura). [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

The front camera seems to be faulty and is throwing warning lights on the Dash. Lane keep assist system, front collision and adaptive cruise control lights show up. These warnings disappear when the car cools down, but does appear again

The front camera failure. Needs replacement. Camera apparently is used for the ACC , lane departure assistance.
