2017 Acura MDX driver assistance problems

Filed Oct 15, 2026 · Body, Driver assistance · NY · crash

As I was driving in a stop and go traffic jam, the vehicle would not go forward although I was pressing on the gas pedal, the engine stall and when it finally reacted after pressing it for the second time it went too fast that I couldn’t stop in time to avoid rear ending the other vehicle, the emergency braking system did not function properly either. This has happened multiple times even when I driven on highways and there’s incoming traffic and the engine goes on stall. But this time it led to an unavoidable accident. I have been concerned for a long time about this issue but I have never received a recall to remedy this problem.

Brake system, Cruise control, lane keeping system get malfunction erratically (ever since 2022, and has been like this), and one of the two sets of brakes never wears off (More than 100 K mileage now (Oct. 2026) , one set of brake pads still is still have sufficient life and does not seem to require replacement. Additiionally, recently (August 2026) the electronic system has gone very bad, the dashboard automatically restarts, headlight turns on, and trying to engaging something, then turned off automatically, then a new cycle starts, and even I turned off again, the cycle will restart until battery is drained and dead, if I do not lock the car (and I had to replace a new battery that was used for less than 1.5 year. If I lock the car, the car will start the same cycle and will honk, and honk, until the surrounding people had to remove the car.

The contact owns a 2017 Acura MDX. The contact stated that while driving, the Adaptive Cruise Control (ACC), brake, and Lane Keeping Assist System (LKAS) warning lights were intermittently illuminated. The contact associated the failure with the brake pads, which had not been replaced since the vehicle was purchased brand new; however, the dealer confirmed that the brake pads were in good condition. Additionally, the contact stated that there were electrical failures after the vehicle was parked. The steering wheel was raised, and the warning light was illuminated while making a continuous clicking sound, and the horn was honking continuously while the vehicle was parked and locked. The electrical failures caused the battery drain and the battery was replaced. The contact stated that several attempts were needed to jumpstart the vehicle. The contact stated that there was an abnormal sound coming from under the hood. The vehicle was taken to the dealer on several occasions; however, the cause of the failures could not be determined. The manufacturer was notified of the failure by phone. The failure mileage was approximately 60,000.

The forward facing camera or monocular attached to the windshield has malfunctioned and is a wide spread issue across multiple models and years. When this item fails due to high heat which causes the camera (CMOS Image sensor) to degrade, the owner is given a slew of warnings and loses a lot of functionality. The dealership quotes an enormous amount of money to replace/calibrate the camera typically between $1500-2500 depending on location. Functionality that is lost includes cruise control, adaptive cruise control, lane departure warning, lane keeping assistance and most importantly adaptive braking. There are also numerous dash lights and repetitive warnings that pop up for each bit of functionality that is broken. So while driving the user will see changing text and hear beeps to inform the driver of these deactivated features which is a major distraction and takes away from the drivers concentration on safe driving. Looking online this issue has been reported by drivers of multiple models and years of both Honda and Acura which means it is wide spread and should be classified as a recall. Just some of the models mentioned are Acura MDX, RDX, TLX, Honda Civic, Accord, CR-V, Ridgeline, Odyssey and potentially others. There is no reason that a camera should fail across all these models spanning over a decade at such high numbers outside of an engineering failure that Honda does not want fork out money for to keep their drivers safe. A couple example part numbers would be 36160-TYS-A02-M1 and 36160-TJB-A040-M1.

I am reporting repeated failures of the front safety camera / Collision Mitigation Braking System (CMBS) on my 2017 Acura MDX Tech (FWD). The vehicle has experienced intermittent and sudden loss of all ADAS safety functions, including CMBS, Lane Keeping Assist, Adaptive Cruise Control, and Road Departure Mitigation. The failures occur without warning, while driving at normal speeds. The dash displays “Safety Support System Problem,” “Collision Mitigation System Problem,” “Lane Keeping Assist Problem,” and related alerts. When this happens, all forward‑facing safety systems shut down, increasing the risk of collision. The issue is persistent and unpredictable. It has occurred in clear weather, dry roads, and normal driving conditions. The vehicle does not have the Advance package or surround‑view system; this is the standard Tech‑package front camera. Multiple Acura service departments have confirmed the problem is caused by a faulty front monocular camera module (part number 36160‑TZ5‑A36). Acura has superseded this part several times (A63, A64, A65, A66), indicating an ongoing design or reliability issue. Replacement cost is extremely high, and the failure disables federally‑relevant safety systems. This is a safety‑critical component. When the camera fails, the vehicle loses collision‑avoidance capability, lane‑keeping assistance, and adaptive cruise control. The failure happens while the vehicle is in motion, creating a risk of rear‑end collisions or lane‑departure accidents. I am requesting the federal safety agency review this issue for potential defects in the Acura MDX front safety camera system.

Problem Description: I am reporting a safety-related issue affecting multiple driver assistance systems on my 2017 Acura MDX. While driving, the vehicle displays several warning messages at the same time, including: Adaptive Cruise Control (ACC) Problem Lane Keeping Assist System (LKAS) Problem Road Departure Mitigation (RDM) System Problem Collision Mitigation Braking System (CMBS) Problem When these warnings appear, all of these safety systems become unavailable. The warning indicators remain on, and the systems do not function even after restarting the vehicle. The 12-volt battery was replaced approximately one month before this issue began, and the engine starts and runs normally. Despite the new battery, the warnings continue to appear, making the vehicle's advanced safety features unusable. This appears to be a widespread issue reported by many owners of the 2017 Acura MDX. Since multiple critical safety systems fail simultaneously, I believe this may be related to a defect in the vehicle's electrical system, charging system, control modules, wiring, or communication network. Because these features are designed to help prevent accidents, their sudden loss creates a significant safety concern. I respectfully request that Acura investigate this issue and consider issuing a recall or extending warranty coverage if a common manufacturing defect is identified.

I am reporting a severe safety defect regarding the sudden, unprovoked failure of the AcuraWatch driver-assist camera system (affecting LKAS, ADAS, and the Collision Mitigation Braking System), which directly and unexpectedly alters the vehicle’s powertrain and driving dynamics without driver input. While driving, the front windshield monocular camera module experienced an internal electronic failure, immediately lighting up multiple critical safety warning indicators on the dashboard and permanently disabling all forward collision prevention and lane-keep capabilities. I urge the federal safety agency to open a safety defect investigation into 2016–2019 Acura MDX models regarding camera system degradation and its hazardous, cascading impact on transmission shift timing and vehicle deceleration behavior.

Various warning lights appear randomly for collision system, lane departure system and brake system and the radio power glitches on/off while driving on highway. I tested the battery and it's good. At one point I was just about to enter a car wash and the radio power glitched off and then a transmission warning appeared and the car shifted to N and I couldn't shift to Drive. I pushed the P button and the dash just showed a blinking P with the transmission warning. With a whole line of cars behind me for the car wash I was in a panic of course. I turned the car off for about a minute and restarted and was able to get it back to normal but had this issue happened while driving then It would've been dangerous.
