2019 Acura MDX Driver assistance Problems

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).

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.

Vehicle Make/Model/Year: 2019 Acura MDX Component Affected: Forward Collision Avoidance / Lane Departure / ADAS (Front Camera System) Summary of Issue: I am filing this complaint regarding a recurring and dangerous issue involving the front windshield-mounted camera on our 2019 Acura MDX. After purchasing this vehicle and driving approximately 5500 miles in Las Vegas, multiple critical safety warnings began appearing on the dashboard, including: •“Collision Mitigation System Problem” •“Road Departure Mitigation System Problem” •“Lane Keeping Assist Problem” •“Adaptive Cruise Control Problem” These warnings occur continuosly. The warning lights won’t turn off, resulting in the complete shutdown of essential Advanced Driver Assistance Systems (ADAS). Safety Concerns: This camera-related failure disables major safety features designed to prevent accidents. The driver is left without automatic emergency braking, lane keeping, or adaptive cruise control. This is especially dangerous at highway speeds. Acura has not issued a recall, despite the widespread nature of this problem and documented cases in other hot-weather regions. Service Experience: We purchased the vehicle used from a Cadillac dealership. The issue began approximately 3 months after purchase. A mechanic confirmed that the front camera system is likely malfunctioning due to heat exposure—a known problem with this model. Why I’m Reporting: I believe this is a safety defect that should prompt investigation. Acura appears to have issued Technical Service Bulletins (TSBs) but has not taken action to proactively notify owners or issue a recall. This defect compromises driver and passenger safety and puts others at risk.

Forward Collision Mitigation braking randomly activates and slams on the brakes despite no cars/obstacles/items in front of it. I have luckily not been rear-ended, but I've had several close calls when driving in traffic (car noses dipping behind me). The dealership has so far been unable to replicate this issue and stated that unless they can replicate there is nothing they can/will do to fix the issue.

I was yielding to make a left hand turn , in the middle of the intersection, and my car turned off and wouldn’t turn back on. In addition the car occasionally jerks as I’m driving almost like if it changes gear. Sometimes I can’t get the car in park position I have to press the button multiple times. The recall going on right now can cause a fire crash or injury and they cannot replace the parts until April 2024 and I don’t feel safe driving my car.

My car was purchased with 12,000 miles and supposedly worn tires. Because of that, I went to the dealership to get new tires and an alignment since the car was always pulling to the right. My car has been at the dealership four times for the same problem, and they still haven't fixed it. My car continues to constantly pull to the right, and when I use the cruise control, it stays above the other cars to the right, causing it to suddenly pull to the left, deactivating the speed control and losing control. The dealership's recommendation is to stop using the speed control."

I was getting ready to pass a semi and when I went to accelerate I had no power. I pushed the pedal several times with no power. Then it finally kicked in and the car accelerated. I was almost rear ended due to me losing power. This has happened multiple times. No lights ever come on. I am also experiencing the car completely shutting off while stopped. When it does this, a message pops up that I need to shift to park. It takes a few tries and then I can restart the car. I have taken it to the dealership and they can’t replicate either issue. They told me there are no TSB’s on these issues. Dates this occurred in 2021: 8/27, 9/9, 10/5, 11/5. Dates this occurred in 2022: 3/4, 3/28, and 4/10.
