1 Warning problem

Failure Date: 04/02/2026

The multipurpose camera on my 2018 Acura Mdx intermittently fails and stores dtc u3000-49. When the failure occurs, multiple Acurawatch/Honda sensing safety systems become unavailable, including collision mitigation braking system (cmbs), adaptive cruise control (acc), lane keeping assist system (lkas), and road departure mitigation (rdm). The vehicle displays numerous safety-related warning messages on the dashboard. The issue is intermittent and appears to occur randomly. In many cases, the warnings disappear after the vehicle is shut off and immediately restarted. This behavior can be observed in the attached video, where the warnings clear following a restart at approximately 1:08 into the recording. The vehicle retains its original factory-installed windshield and related components. The windshield has never been replaced, modified, or damaged, eliminating a common cause of camera calibration or alignment issues. I contacted Acura client relations and opened case number 16409871 regarding this issue. Acura declined to acknowledge the problem as a manufacturing defect and did not offer coverage for diagnosis or repair. Because the multipurpose camera is a critical safety component responsible for advanced driver assistance and collision avoidance functions, its intermittent failure raises significant safety concerns. The fact that the issue temporarily clears after a restart suggests a potential defect in the camera hardware, software, or related vehicle systems rather than normal wear and tear. I understand that other Acura and Honda owners have reported similar multipurpose camera failures. Given the safety implications of losing collision mitigation, lane-keeping, and driver assistance features while operating the vehicle, I respectfully request that NHTSA investigate whether this condition constitutes a safety-related defect and whether a broader pattern exists among affected vehicles.

2 Warning problem

Failure Date: 10/01/2025

Front multipurpose camera is starting to fail intermittently. Multiple warnings pop up (lkas, auto high beam, forward collision warning).

3 Warning problem

Failure Date: 08/15/2025

Front camera stopped working at 65 000 miles. Seems to be a faulty part as many hondas and Acuras have the same problem and the dealer wants over $2000 to replace a $700 part that sounds like less than 45 minutes to replace.

4 Warning problem

Failure Date: 05/28/2025

5 waning lights on : adaptive cruise control , lane departure warning , lane keeping assistance , front light, and the emergency braking . Service crew at Acura dealer told me that the front multipurpose camera has internal error. It is very dangerous since all these functions must be fixed before I can drive it on road.

5 Warning problem

Failure Date: 03/03/2025

The front camera seems to be faulty and is throwing warning lights on the dash. Lane keep assist system, front collision and adaptive cruise control lights show up. These warnings disappear when the car cools down, but does appear again.

6 Warning problem

Failure Date: 10/12/2024

We experienced multiple/many warning lights all at the same time. Systems not working. Repeated every time. The Acura dealer diagnosed the problem to the dtc u3000-49 multipurpose camera internal electronic failure. Replaced the unit and they performed a couple of calibrations.
