The front multipurpose camera system failed, triggering multiple safety warning lights simultaneously, including ACC (Adaptive Cruise Control), LKAS (Lane Keeping Assist System), and related camera-dependent safety systems, along with a "Multipurpose Camera Unit" fault code U3000-49. The failure pattern has been intermittent and inconsistent: on some drives, warning lights are absent at startup and appear after several minutes of driving; on other occasions the warnings appear immediately at startup; duration before onset varies from trip to trip. This vehicle falls within the range covered by a prior Honda recall (Recall 19-020 / the federal safety agency Campaign for 2019-2020 Passport) addressing software programming errors in the front control module causing improper display of instrument panel and delayed or missing rearview camera images. The current failure presents similar camera-related safety system symptoms. A dealership inspection recommended replacement of the multipurpose camera unit at an estimated cost of approximately $2,000, without confirming the root cause of the failure. Safety concern: Loss of ACC, LKAS, and related driver-assist camera systems while driving, with warnings appearing unpredictably during operation, some minutes into a drive rather than at startup, suggesting a fault that may not always be evident during a pre-drive check.

The Nidec OEM part number 36160-TGS-A03-M1 has failed and causing all five of these alerts to appear as warnings: 1.Road departure mitigation problem 2.Collision Mitigation problem 3. Lane keeping assist problem. 4. Auto high beam problem. 5 Adaptive cruise control failure I don't know if the Nidec part is OEM from Honda and I believe the materials used by Nidec are creating the issue. I thought the Honda OEM part for this camera came from Bosch. The German part appears to made from aluminum, the Nidec part might be a plastic or other material. I am researching the failure rate on your part as I don’t believe there is a heat sink as part of the configuration and the part seems to be out of stock everywhere I look.

The first major issue I just started running into at about 90,000 miles is the engine auto start stop feature. I usually disable it when I drive due to the inability for the car to provide adequate start from a stop, but when I don’t, I’ve had the vehicle completely stall on me at a stoplight and won’t let me restart the vehicle for several minutes leaving me stranded and vulnerable sitting in a lane on a highway. I’ve had about a dozen instances of this issue now over the last several months. The second issue is with the adaptive, cruise control or the emergency, stopping on the vehicle where it will jam on the brakes, even though there are no cars in front of me it inaccurately picks up vehicles in the oncoming lane. There are more than 8 feet separated from my vehicle. I have had the system recalibrated and have complained about it at the dealer, but I’ve been told that there’s nothing wrong with it. Just thought I’d report that as well because it’s almost got me into several accidents by jamming on my brakes for no reason and almost being rear-ended.

Adaptive cruise control works well most of the time. Occasionally, it ignores stopped traffic and closes to a dangerous distance. It then slams on the brakes and all warning lights go on. The sensors are defective. On two lane roads, the sensors detect oncoming traffic and flash the brake warning light. When on cruise, the sensors detect cars making a left turn when passed on the right, and apply the brakes. The same thing happens when on a freeway in the middle lane passing a car on the right. The false warnings have happened since I purchased the vehicle. It's been to the dealership numerous times. They can't fix it. The cruise problems were discovered on a trip to florida from january to march 2021.

Clark st, ste 2, chicago, il 60610, (312) 766-1095) and a software update was performed for the instrument panel to show the correct speed.
