2020 Honda Passport Driver assistance Problems

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 / NHTSA 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.

It's a sunny day in Florida and approximately at [XXX] while traveling straight on a public roadway, the vehicle directly in front of me moved into the left-turn lane, completely clearing my lane of travel. As I actively accelerated to pass the turning vehicle, my Honda’s Collision Mitigation Braking System (CMBS) inadvertently activated despite my lane being completely clear and unobstructed. The emergency automatic braking engaged forcefully just after I passed the vehicle in the left-turn lane. This unexpected, false-positive braking event caused a severe, rapid deceleration that nearly resulted in a rear-end collision by the vehicle traveling behind me. This exact situation has occurred on 3 other separate occasions. I'm in fear of being rear-ended, especially with my kids in the car, because my vehicle body language prior to the forceful braking has been acceleration. The drivers behind me are likely to see my acceleration and proceed with their own acceleration just to be blind-sided with my vehicles sudden and hard braking. It's a disaster waiting to happen, especially on busy roadways. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Numerous times over the past year, the Passports forward collision warning system and automatic braking system have incorrectly alerted and automatically braked the vehicle when it was not warranted in the situation. This occurs most frequently when on a two lane undivided road (with one lane traveling in each direction). While driving on these roads, the vehicle is frequently incorrectly judging a head on collision will occur with oncoming traffic, and start the audible and visual warning system and sometimes also automatic braking. In these instances both vehicles are well within their side of the roadway and no collision is remotely close to occurring. However the automatic hard braking could cause a rear end collision with the vehicle behind me. Seems to be most common on curvy sections of roadway.

TODAY, I WAS MERGING OFF [XXX] TO [XXX] WITH NO CARS OR OBSTACLES AROUND AND THE AUTOMATIC BRAKING SYSTEM DEPLOYED AND THE CAR BRIEFLY SLAMMED ON THE BRAKES AND WHEN I PRESSED DOWN ON THE GAS IT RELEASED ITSELF. LUCKY NO CARS WERE BEHIND ME AT THE TIME BUT IT DID SCARE MY WIFE AND I AT THE TIME. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Every time I am on a two lane road and am navigating a right hand curve at any speed and a white car or truck is in oncoming traffic, in their lane, the vehicle alerts me to brake. The system beeps and flashes BRAKE! on the instrument panel. This happens each time as if the cameras are not calibrated correctly. It's incredibly annoying and happens every time even with the system turned down as low as Honda will allow. This could be very distracting to many drivers. I have chosen to just ignore the system which is not a good situation.

On Nov 9, 2024 I was pulling into a parking spot in a public parking garage, after turning 2 tight corners to approach the parking spot. About half way into the parking spot, the car suddenly lurched and accelerated and I crashed into a 90 degree concrete corner wall! It happened SO fast, without any warning sounds or ABS brakes deploying. The entire front passenger corner of my car was badly damaged. Luckily I was not injured, nor were there any other vehicles or persons involved. It is just not possible that I could have personally pulled into a parking spot at such a high speed as to cause such extreme damage to the vehicle! I drove the vehicle to a body shop on 11/11/24, which was one recommended by my insurance company. The vehicle was inspected by the body shop, which was directly in contact with my insurance company. I did ask the shop to make sure the mechanic checked for any safety issues during repair, as I was concerned as to the cause of the accident. I have an impeccable driving record and I cannot explain how such an accident could happen! I had no issues with the car previously. Upon further inspection into the damage, on 1/3/25 it was finally evaluated as a total loss, as there was damage to the frame and other issues! I did receive a statement on 1/3/25 from the body shop that there was a "fault in the system, causing gas pedal lock, which might be cause of accident". I felt I had to report this possible issue that resulted in a total loss and obviously could have injured myself, others or other vehicles!

Lately the automatic braking system has been applying the brakes unnecessarily when there's nothing in front of me. That is an escalation from the at least 3-4 times a week the brake sign will light up and the steering wheel will shake to let me know to brake but there's no car in front of me but rather a car in the lane going the opposite direction. I love in West Virginia and there's a lot of two lane roads and it happens a lot of those two lane roads. Even ones that are clearly marked with lines. I have not taken it in to the dealer but have been in groups that have complained of the exact same issue. This happens from. Highway speeds to low town speeds as well.

Nothing has failed currently, more so the system overreacts to EVERYTHING. Trucks nearby, swerve. Guardrails, center lanes, etc. it’s insanely inconsistent and I’m not surprised it’s caused accidents, the ACC and brake assist need to be fixed on these cars

While driving my brake warning light on the dash will come on for no reason, it will flash, beep and the car will slightly shake (similar to when the car leaves the lane without using your turn signal). This happens every time I drive. It’s not occasional. I have mentioned it to the dealer a couple of times during normal service but they say the sensor is fine. It obviously isn’t. I’m afraid it will lead to an unfortunate accident by not activating when there is a real danger of a crash. I can’t fill in every date below but the most current incident is noted below

The vehicle constantly activates the collision warning system any time on a 2 lane road and a car approaches the opposite way. The steering wheel shakes and flashes the brake on dash. Not only is it annoying it is dangerous because it catches you off guard nearly cause accidents. I’ve had in for service one dealer said it was bugs on the camera and another told me they would only look at it if I paid $200.00 the vehicle is still under warranty.

The cmbs keeps flashing the brake warning light when I’m changing lanes to a center turn lane. This happens at least 2-3 times weekly. I’ve also had it brake going through a stop light when no one was in front of me and almost got me rear ended. I have not taken it to a dealer or shop to have them reproduce it because I know there’s nothing they will do to fix it so I’m not going to waste the money until I know it will be fixed by taking it in.
