Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My cruise control, automatic lane changing indicator light indicator, brake indicator light, high beam light indicator lights all keep coming off and on. Researching it on YouTube states that it’s the camera on my windshield getting too hot and it’s a known issue. It’s $1800 To fix but others have stated they get fixed and it doesn’t resolve the problem. Asking for your help.”

NHTSA complaint #11741032, filed 2026-05

“Multiple errors Lane departure and advanced driver support, ACC LKAS, auto high beam, and braking system. Looking into this more i see lots of people with the same issue failing front facing camera and not a cheap fix. Is there any current investigations into this problem or a software upgrade? I clear the errors and they come back once car is turned off and back on. If no fix to the current system there should be a way to disable LKAS and ACC without spending $2000 to replace the system.”

NHTSA complaint #11759085, filed 2026-08

“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.”

NHTSA complaint #11688550, filed 2025-09

“My 2020 Acura MDX is throwing up multiple dashboard warnings related to the camera sensor—involving systems like Adaptive Cruise Control, Lane Keeping Assist, Collision Mitigation, and Road Departure Mitigation. These systems rely heavily on the Multipurpose Camera Unit mounted near the rearview mirror. I took it to my Acura Dealership Service and they concluded it's the Multipurpose Camera Unit that's causing all these dashboard warnings. They are charging me $1800+ for a new one to be installed. …”

“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.”
