ELECTRICAL SYSTEM

Potential Consequences:

I own a 2020 Acura MDX. On two separate occasions, the Auto Engine Idle Stop system failed to operate while depressing the accelerator pedal while at a stop. Several unknown warning lights were illuminated on the instrument panel. The vehicle shuts off and the I had to manually restart the vehicle after the failure. I have not contacted the dealer yet but based on what I have found here I am not the only one that this is happening too. It is awful to be stopped in rush hour traffic and having people honking at me and potentially be the cause of an accident. The vehicle has not been repaired. The failure mileage was approximately 35,000 and 38,000 miles.

ENGINE

Potential Consequences:

When idle stop is on and I come to a stop, the car shuts off and switches to neutral. It has to be put in park to start it back up. This is a safety concern because the vehicle is essentially stalled until you're able to put it in parked and restart it, which could cause an accident. The dealer is aware of the problem as it's been discussed the last two times that I've taken my vehicle in for recalls. According to the dealer, there is a recall for this issue but it's not for 2020 MDX, it's for 2022-2025.

ENGINE

Potential Consequences:

I am writing to formally express my concern regarding a recurring issue with the Auto Start/Stop feature in my 2020 Acura MDX. This feature, which is intended to improve fuel efficiency, has instead caused unexpected and unsafe engine shutoffs while the vehicle is in operation. On multiple occasions, the vehicle has failed to restart promptly after the engine shuts off at a stoplight or in traffic, creating a serious safety hazard. The delay or failure to restart can leave the car temporarily disabled in active traffic, placing both myself and other drivers at risk.

Potential Consequences:

Auto Idle Stop issue where engine did not restart. Occurred multiple times in April/May of 2024 and Vehicle Stability Assist Code U3006-16 appeared on the Infotainment screen. Taken to dealer who was unable to replicate the problem. The U3006-16 code appeared again in February 2025 but the car did not experience the restart issue at that time. The U3006-16 code appeared again on April 6, 2025 while exiting a freeway after a 20 minute drive and the engine did not restart after Auto Idle Stop engaged at the second intersection. Taken to dealer and unable to replicate the problem and supposedly cleared the codes. On May 21, 2025 the U3006-16 code appeared again while exiting a freeway after a one hour drive but the car did not experience the restart issue at that time. Took car to dealer who checked a bunch of things and cleared the code,

ENGINE

Potential Consequences:

At 101,841 miles, noticed ticking coming from the engine as it was idling. Acura of Limerick dealership diagnosed the issue coming from the bottom of the engine as a rod knock. They feel the problem is internal to the engine and suggest replacing the engine at my, I the owner's cost. After reviewing blogs and information on recalls on the internet, this issue seems in line with other rod bearing issues with this 3.5L V6 engine. But my Vin is not identified as having the recall issue? This seems incorrect as my Vin should be covered as it seems to be the same problem.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Potential Consequences:

I am reporting a failure of the multipurpose front windshield camera in my vehicle, which resulted in the loss of multiple safety systems including Lane Keeping Assist System (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), Auto High-Beam, and Collision Mitigation Braking System (CMBS). These features are critical to safe driving, and their sudden deactivation poses a serious safety risk to both the driver and others on the road. This issue required costly repairs. I believe this represents a safety defect that should be investigated by NHTSA.
