2018 Acura MDX: multiple warning lights

Filed Jul 1, 2026 · Driver assistance · OR

The forward facing camera in the windshield went out causing all these systems to stop working and dash light up like a christmas tree. I cant even use normal cruise control. Dealer wants $1700 to replace it. From what I am reading online this is a very common problem and Acura even superseeded the part. Was that due to failures? I have yet to get this repaired as it is so expensive but i would really like these safety features. 36160-TZ6-A36

While driving the car, several warning lights turned on all at once, saying that the following components were disabled: Lane Keep Assist, Adaptive Cruise Control, Automatic High Beams, and Collision Mitigation Braking System. Not being able to use these features is more dangerous, not to mention that the warning lights associated with their disabling are distracting (making it likely that, if a more serious warning was flashing, it would not be noticed by the driver) and cannot be turned off without an expensive replacement. Yes, the problem was confirmed by a trusted mechanic (the warning lights will not turn off so it's not hard to confirm), who indicated that the radar camera needed to be replaced. No, the component has not been inspected by others. There was no warning of the problem.

While accelerating, the vehicle to decelerated rapidly, the gas pedal became unresponsive when pushed down. Numerous warning lights started Additionally, the vehicle shifted into neutral while the vehicle was being driven and would not shift out even after stopped. I was on a very busy 6 lane highway going 80 mph in thanksgiving traffic, my wife, 1 year old and 3 year old were in the vehicle.

We experienced multiple/many warning lights all at the same time. Systems not working. Repeated every time. The Acura dealer diagnosed the problem to the DTC U3000-49 Multipurpose Camera internal electronic failure. Replaced the unit and they performed a couple of calibrations.

This car has repeatedly had issues with delaying to take off when I touch the gas pedal. Once the pedal is depressed there is a long delay before the car actually moves. Two days ago as I was driving at around 35mph all warning lights came on and the car started jerking as it was trying to slow down or stall. I was able to get back to my home luckily I was only up the street and was able to drive under 30mph and had to pull off the road several times because it kept jerking almost as if someone was repeatedly slamming on the brakes. I had a mechanic hook a reader up and was able to determine it was the high pressure fuel pump. Acura claims my car has no open recalls but I believe although it may not be currently it obviously should be part of the recall involving the same exact issue. The warranty expired 3k miles ago ironically, but given this issue has happened to other cars of the same make and model and given the recall for this same part on other cars like mine just with a different vin I believe it should be covered as it is a major safety concern. The car jerked very hard and luckily I did not have my kids with me and luckily no one was too close to me when my car starting stopping in such an forceful way. If I was on a Highway I would have probably been involved in an accident as the car was attempting to go into limp mode due to the failure of the fuel pump and was aggressively shifting down when I was only going 35mph I can only imagine what could happened if i was traveling double that speed.

Keyless Access/TPMS Control Unit is failing. Vehicle randomly behaves where all dash lights blink on and off, head lights turn on, car alarm intermittently alarms, and motorized steering wheel moves. It is unknown if there is any malfunction to ADAS or other systems due to this random behavior. Vehicle cannot be parked with the battery connected as all of these events intermittently happen and drains the battery. The behavior is so startling and a concern to drive that it is unknown if it will completely fail and shutdown while driving. For example, the Keyless Control Unit could potentially fail to recognize the key while driving and then the vehicle would shutdown as if being stolen. Vehicle has been inspected by the dealer, confirmed malfunction and noted occurence with other customers vehicles of same make and model. Diagnostic report by dealer states the failing component.
