While driving on a residential street under normal daylight conditions, the forward collision warning and automatic emergency braking system failed without warning. A dashboard message appeared instructing me to clean the windshield and stating that collision avoidance services were unavailable. The windshield was clean and unobstructed. There was no precipitation, glare, or debris. The failure occurred while the vehicle was in motion. I had no indication of whether the vehicle was safe to continue driving or whether I should stop immediately, and no way to know whether the fault was limited to the camera or whether other systems were affected. There was no prior warning, no gradual degradation, and no fault indication before this event. I purchased this vehicle in part for its advanced driver assistance systems and rely on forward collision prevention in daily driving. That protection is now unavailable, and I am driving without a crash avoidance system I was sold and expected to have. I took the vehicle to an authorized dealer for diagnosis. The dealer determined that the forward facing camera module must be replaced and recalibrated, and quoted $2,700. No recall or technical service bulletin was identified. I believe this constitutes a safety defect. A primary crash avoidance system failed spontaneously under normal operating conditions on a vehicle marketed on its safety technology. The repair cost is also high enough that many owners will defer or decline it, leaving vehicles on public roads with disabled collision avoidance. I request that NHTSA investigate the failure rate of this camera module and consider a safety recall.
Add auto high beam problem to the above adaptive cruise control, lane keeping assist, and collision mitigation. Suddenly got several warning popups and persistent warning lights on related to the identified issues. We just replaced the battery a few months ago, and didn't have any of these problems until this week. Now, it happens every time we start the vehicle. We did the recall software upgrade. I suspect these problems are related to that software upgrade. Many people online report identical problems without solutions. Please advise re next steps for how to resolve.
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 capabilities compared to its certified design. * there is a risk that drivers may not immediately recognize the loss of functionality or may assume partial systems are still operational. After experiencing this issue, I discovered numerous reports from other Acura Mdx owners describing identical multipurpose front camera failures, often at similar mileage, with similarly high repair costs. This suggests a potential systemic defect rather than isolated wear or misuse. I respectfully request that NHTSA review this issue to determine whether this represents a safety-related defect requiring investigation and possible recall. Given the role this component plays in multiple safety systems, I believe this issue warrants formal evaluation.
