2018 Acura MDX Driver Assist & ADAS Problems

Warning lights for Collision Mitigation System, Road Departure Mitigation, Adaptive Cruise Control. Lane Keeping Assistance, Auto High Beam. Features are now disabled causing safety issue. Dealer confirms issues and recommends repairs that have not not been solved by others online. Errors appeared before battery Failure in March 2026. Battery was replaced. Common complaint by many online. Need recall to fix.

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.

Front multipurpose camera is starting to fail intermittently. Multiple warnings pop up (LKAS, Auto High Beam, Forward Collision Warning)

Front camera stopped working at 65 000 miles. Seems to be a faulty part as many Hondas and Acuras have the same problem and the dealer wants over $2000 to replace a $700 part that sounds like less than 45 minutes to replace.

Got multiple warnings, systems don't work: Collision Mitigation System, Adaptive Cruise Control, Lane Keeping Asist, Road Departure Mitigation System. All those additional systems designed for safety are no longer working. The front camera failed, as confirmed by the dealer. Part is available for inspection.

Emission systems problem and parking brake problem lights came on simultaneously. Mechanic has not been able to figure out the problem Replaced vent valve

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.

5 waning lights on : Adaptive Cruise Control , Lane Departure Warning , Lane Keeping Assistance , front light, and the emergency braking . Service crew at Acura Dealer told me that the front multipurpose camera has internal error. It is very dangerous since all these functions must be fixed before I can drive it on road.

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

I can't drive the vehicle safe with the entire gauge cluster indicators are all on. Cluster making loud beeps and noises not being able to shut or clear the code indicators. The acura dealership is saying the camera is overheating and not safe to drive.

back-up camera is useless at night posing a hazard to anyone behind the vehicle. Honda knows how to fix the problem as witnessed by my 2018 Odyssey which is excellent. The problem has spanned over many years of the MDX before 2016 and after 2019. Having a working backup camera is paramount for any SUV because of the limited visability. Acura Service could not remove the problem

2018 purchased a little more than a month ago as a certified used Acura. Twice now we have been overridden by the automatic forward collision detecting something in front when NOTHING was there. Once on the freeway went from 70mph to 15 quickly and almost got rear ended. Just now on city street car stopped in the middle of intersection while turning left and overrides driver pressing gas pedal in both cases. Makes us scared to drive suv further and we have turned off that feature to see if it still happens.

My vehicle has similar behaviors to the most recent investigation that is happening with the investigation of the Honda Accord and CRV noted in this article: https://static.nhtsa.gov/odi/inv/2022/INOA-PE22003-5540.PDF. On a handful of times while driving on the freeway, my car has unexpectedly decelerated when passing another vehicle, or on a curve the adaptive cruise control slows the vehicle down. On one occasion, the car suddenly applied the brakes and slowed us down at least 10mph. In any of these instances, I have not had anyone following, but could have caused issues if there was.
