Adaptive Cruise Control problems of the 2018 Acura MDX

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.

Warning lights for collision mitigation system, road departure mitigation, adaptive cruise control. Lane keeping assistance, auto high beam. Features are now disabled causing safety issue. Dealer confirms issues and recommends repairs that have not not been solved by others online. Errors appeared before battery failure in March 2026. Battery was replaced. Common complaint by many online. Need recall to fix.

While driving the car, several warning lights turned on all at once, saying that the following components were disabled: lane keep assist, adaptive cruise control, automatic high beams, and collision mitigation braking system. Not being able to use these features is more dangerous, not to mention that the warning lights associated with their disabling are distracting (making it likely that, if a more serious warning was flashing, it would not be noticed by the driver) and cannot be turned off without an expensive replacement. Yes, the problem was confirmed by a trusted mechanic (the warning lights will not turn off so it's not hard to confirm), who indicated that the radar camera needed to be replaced. No, the component has not been inspected by others. There was no warning of the problem.

The front camera failure. Needs replacement. Camera apparently is used for the acc , lane departure assistance.

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.

While operating the vehicle, multiple driver-assist warning indicators illuminated on the dashboard, including lkas (lane keeping assist system), acc (adaptive cruise control), and cmbs (collision mitigation braking system). The systems either disengaged or functioned erratically during normal driving conditions. At times, the vehicle failed to maintain lane position, abruptly disengaged adaptive cruise control, or displayed collision alerts when no obstruction was present. Now it is constant. Safety impact: the failure of the lkas, acc, and related systems can cause unexpected loss of vehicle assist functions, leading to abrupt speed changes or compromised lane control, increasing the risk of collision if not promptly corrected.

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.

My vehicle has similar behaviors to the most recent investigation that is happening with the investigation of the Honda accord and crv noted in this article: https://static. Nhtsa. Gov/odi/inv/2022/inoa-pe22003-5540. Pdf. On a handful of times while driving on the freeway, my car has unexpectedly decelerated when passing another vehicle, or on a curve the adaptive cruise control slows the vehicle down. On one occasion, the car suddenly applied the brakes and slowed us down at least 10mph. In any of these instances, I have not had anyone following, but could have caused issues if there was.
