FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The subject 2019 Acura MDX model includes the tech package which adds several safety features that function through a windshield mounted camara/radar. The system has malfunctioned and none of the safety features are working. The dash displays the following messages: Collision Mitigation System Problem Adaptive Cruise Control Problem Lane Keeping Asist Problem Road Departure Mitigation System Problem automatic headlight system problem At the bottom of the dash, I see Brake System, Crash Warning and Lane Departure lights on as well. Acura is charging $2,319 to replace this unit in addition to a $270 diagnostic fee. This issue is widely reported as a significant issue in several model years for the MDX and should be part of a safety recall. The Acura technician acknowledged this issue is common. I should add this is the second major electronic issue with this MDX within the last several months. The prior issue was multiple system failure warnings that Acura determined were caused by a faulty wiring harness at a $1,604 cost, plus a $255 diagnostic fee. Please note I am the original owner of the vehicle and it has never been in a collision. Additionally, the system has recently mistakenly activated the brakes at very low speed and warned against collisions with other vehicles traveling in the opposite direction while on a curve.

On 04/03/2026, 6:04 PM, Acura MDX 2019, Base, SH-AWD, at 105,254 miles on the odometer, posted U3000-49 control module internal electronic failure. The fault appears to be at the 36160-TYS-A02 camera assembly monocular results in a series of cascading errors on the dash with indicators on for LKAS (Lane Keeping Assist), ACC (Adaptive Cruise Control), CMBS (Collision Mitigation Brake System), brake and transmission warning lights that blink continuously. The sudden lost of safety system especially at highway speeds places extreme risk to occupants of vehicle and other drivers sharing the roadway. The current TSB 23-008 does not repair fault, origin of fault not software, but requires replacement of front camera assembly (36160-TYS-A02) and recalibration at owner expense. There appears to be a lot of 36160-TYS-A02 camera monocular that either have insufficient solder, cold solder, bad crimps or otherwise that over time results in failure.

When I was at 41,528 miles, May 18, the LKAS, ACC & RDMS errors all turned on at the same time. So those systems just stopped working randomly. When I restarted the car, all errors turned off but it turned on again after 10 days, May 28 with 91,966 miles. I brought it to the Acura dealership and they couldn't replicate it. I think this is an issue because one of the highlights of this car is safety but at random times, those safety systems suddenly stops working and the dealership couldn't do anything about it.

Front windshield camera went bad due to overheating. When malfunction it gives multiple warning lights, everything that has to deal with front windshield camera does not work. Ive hearing multiple and multiple stories online and in person that they too is affected by camera malfunctioning. There needs to be a recall on it as it is affecting way too many people. My car is a 2019 with ONLY 47000 miles pretty much still new. Parts plus labor and camera calibration is $2200

Camera is failing - reportedly due to a bad internal ground-wire. Acura is charging $900 for the part and $1600 for the installation and calibration of a new unit !! Also - the unit is a black color, and located right behind the windshield, so bakes itself to death. Acura should be using white colors inside the space, limit the un-used volume, and recalling the units (or at least providing a low-cost unit) to allow simple replacement and improve safety. Such an important AND EXPENSIVE part should not be failing so often. The MXers.org web site has hundreds of posts about this item. ALSO - the parts should be pre-calibrated! Acura wants several hundred $$ to calibrate it and 4 days to do it. NHTSA should NOT be requiring ADAS technology if it is so fragile and expensive to fix/replace, as in the long-run owners will not maintain it (e..g $2,400 repair bills for a small camera part nad 5 minute change).

San Jose, CA
LANE DEPARTURE: ASSIST
The front camera responsible for forward collision warning and lanekeep has failed. The camera has part number 36160-TYR-A02. It failed on it's own but it could have been alot worse if it failed before a collision occurred. The dealer and independent repair shop said it was the camera code U3000-49 and this was an out of pocket repair. The symptoms include having these error messages on the gauge cluster. Adaptive Cruise, Lane Keep Assist, Road Departure, Collision Mitigation, and Auto High Beam Problem. At first it would intermittently show up but then after a while those errors would not go away.

The windshield camera suddenly failed one day while driving and it ended up disabling all the driver assist systems including the emergency braking, lane keep assist, forward collision, auto high beam, cruise control etc. Over the next few weeks the system kept randomly working and failing during driving every few hours or minutes. The discussion forums are filled with people complaining about the same issue with ALL Honda and Acura vehicles starting 2013 where they camera suddenly fails and then start working intermittently until it eventually fails. It seems Honda is using the same defective camera across all it's Honda and Acura models which is a big safety hazard and they refuse to acknowledge the issue.
