2020 ACURA MDX Forward Collision Avoidance Warnings Problems

I was driving on a normal sunny day when every light on my dashboard came on. I initially panicked thinking my car was going to shutoff while I was driving it. This is in conjunction with the car stalling out when the auto shutoff feature malfunctions. After researching the issue, I realized the safety camera was no longer working and a major concern. A malfunctioning front camera can prevent the vehicle from automatically braking or maintaining lanes, hence increasing the risk of collision. I am requesting that NHTSA investigate the front multi-purpose camera system on the 2020 Acura MDX for potential defect and safety hazard.

This is a safety-related defect involving the multipurpose front camera used for Advanced Driver-Assistance Systems (ADAS) on the 2020 Acura MDX. The multipurpose front camera failed without warning, resulting in the simultaneous loss of multiple ADAS safety features, including (but not limited to) Lane Keeping Assist, Adaptive Cruise Control, Collision Mitigation Braking, and Road Departure Mitigation. These features are integral to the vehicle’s active safety systems and driver awareness. The failure required full replacement of the front camera assembly. The total repair cost was approximately $2,300, which I was required to pay out of pocket because no recall or extended warranty coverage was available. This failure creates a significant safety concern because: * The loss of ADAS functions occurred suddenly and without driver fault. * The driver may rely on these systems for collision avoidance, lane control, and adaptive braking. * The vehicle remains drivable, but with materially degraded safety...

I drove my car in the morning and parked it in the lot for about an hour. After I came back and started my car, the following multiple safety systems displayed on my dashboard at the same time: - Lane Keeping Assist Problem - Collision Mitigation System Problem - Road Departure Mitigation System Problem - Auto High Beam Problem - Adaptive Cruise Control Problem When I took it to the dealership on the same day to diagnose this, they came back and said it was an internal failure with the camera and quoted me around $2200 to replace and recalibrate the camera. These lights just came on out of nowhere, I had no repairs or modifications with my windshield and there were no accidents of any sort. This appears to be a widespread problem among 2020 Acura MDX vehicles with similar camera modules. A malfunctioning front camera can prevent the...

All the sensors are blinking with no damage done to the vehicle no Cruz Control no abs no lane departure and more all sensor is not working

Monocular windshield camera failed for no apparent reason on five-year-old car with less than 50k miles. Dealer cost to fix $2k. My concern is there are an many individuals on the Acura MDX forums complaining of the same problem. It appears to be a relatively common but very costly failure on many Honda vehicles that use similar cameras. I believe this is worthy of an investigation, especially since the camera is necessary for many safety related features to function properly.

I am reporting a failure of the multipurpose front windshield camera in my vehicle, which resulted in the loss of multiple safety systems including Lane Keeping Assist System (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), Auto High-Beam, and Collision Mitigation Braking System (CMBS). These features are critical to safe driving, and their sudden deactivation poses a serious safety risk to both the driver and others on the road. This issue required costly repairs. I believe this represents a safety defect that should be investigated by NHTSA.

2020 acura mdx tech package with 31600 miles, I purchased this vehicle first owner in march of 2021 and about 3 days ago 5/22/25 I get a fault reading for collision mitigation system problem, lane keep assist problem, road departure mitigation system problem, adaptive cruse control problem and auto high-beam problem, all safety feature issues, I brought vehicle to Acura dealership and they scanned for error codes which produced error code#u3000-49 for faulty multipurpose camera unit millimeter wave radar internal electronic failure recommend to replace the wave radar, dealership states vehicle is no longer under warranty and would cost a total of $1500 to get repaired and replaced , this issue should be looked into further for faulty acura part if repair is done what are the chances of it happening again with normal usage of vehicle.

Faulty Windshield camera. which fails due to overheating. and sets off problem lights on the dashboard. lane keep assist , lane departure, brake problem. this seems to be a common problem with this faulty design. to replace this part is $2,000 which who knows if it will fail again. so know one is forced to drive around with the constant problem lights and the uneasy feeling of not having brake assistance when and if needed. this puts not only the driver and passengers lives at risk but the lives of the public.

### 1. **What component or system failed or malfunctioned, and is it available for inspection upon request?** The rearview camera system in my 2020 Acura MDX has malfunctioned. The camera, which is integral to several safety systems in the vehicle, has failed, causing significant safety concerns. The vehicle is available for inspection by an Acura dealership or independent service center upon request. ### 2. **How was your safety or the safety of others put at risk?** The malfunction of the rearview camera directly impacts the **Collision Mitigation Braking System (CMBS)**, **Adaptive Cruise Control (ACC)**, and **Lane Departure Warning (LDW)** systems. These systems rely on cameras and sensors to detect obstacles, maintain a safe following distance, and alert the driver when switching lanes. Without the proper function of the rearview camera, these safety systems become unreliable, increasing the risk of head-on collisions, rear-end accidents, or unintended lane changes, which could lead...

My vehicle will phantom brake and kick on the automatic emergency brake system without cause. It has done it as I was accelerating onto the freeway onramp and almost caused a collision with the vehicle behind me. There was nothing in front of me and no reason to brake. It has happened on several occAsions

I'm not sure if there is a problem with any of the components, but the radar sensor malfunction impacted the vehicle's braking system. Situation: On [XXX], I was driving with my wife and her nephew from my home (Ankeny, IA) to Indiana on [XXX] [XXX] and [XXX] [XXX] . It was snowing that day. As usual, there were other vehicles on the highway, semi-trucks, pickup trucks, cars. The snow was splashing on to my front bumper, lights, radar sensor and windshield. As it was snowing, I did not engage the cruise control feature. We were around 30 miles from Iowa City, I was passing a semi-truck, a message was displayed on the dash to clean the radar sensor. I thought of pulling over in a safe spot to clean it up. At the same time, "front collision off" and "brake system" icon lite up. The road also changed from downhill...
