Started the car Check engine lights and all the other lights came on: tire pressure, ABS,ACC, break, emergency break, collision mitigation system problem, road departure mitigation,VSA. Turned off the car, the lights and check engine lights went away and a few days later while driving car did that again and then it engine decline in speed and died on highway.

False forward collision warnings by model year
What owners say
Lane keeping assist problem light on, collision mitigation system problem light on, road departure mitigation system problem light on, adaptive cruise control problem light on. brake sy stem light on. The vehicle’s multiple camera has failed and it is a common occurrence with this vehicle. Honda has not recalled this and is charging customers upwards of $2500 to replace the camera behind the windshield and recalibrate it. This isn’t an issue based on miles there have been incidents with it happening as early as 30,000 miles. I bought my vehicle used and about 113,000 this started happening
Since purchasing this vehicle new, the Auto Idle Stop (AIS) system on my 2017 Honda Pilot has intermittently failed during the engine restart sequence after the vehicle comes to a complete stop. When the AIS system shuts the engine off and I release the brake to resume driving, the vehicle intermittently fails to restart properly or does not restart at all, preventing the vehicle from moving as expected. In some instances, warning messages, including a collision mitigation message, has appeared on the dashboard before the car restarts. This condition has occurred repeatedly over several years and has happened at intersections, while stopped in traffic, and while stopped on highways. The inability of the vehicle to restart and move creates a safety risk because the vehicle may remain disabled in active traffic when acceleration is needed. The issue was reported to the selling and servicing Honda dealership (Cambridge, Honda in Cambridge MA) multiple times over several years. In August 2025, the vehicle received Honda's prescribed repair under Service Bulletins 23-008 and 23-009, including replacement of the starter assembly, starter relay, and battery. Despite these repairs, the same condition returned less than one year later and has occurred at least seven additional times. The vehicle stalls and sometimes displays the collision mitigation/crash warning message before restarting. In June 2026, the vehicle was inspected again by the dealership. Technicians were unable to reproduce the condition during testing and declined to perform additional repairs. The defect remains unresolved. The vehicle has already received Honda's recommended AIS repair, yet the same stalling and crash mitigation message continues to occur. The intermittent nature of the defect makes it difficult to reproduce during short dealership evaluations, but it continues to occur during normal operation and presents an ongoing safety concern.
Collision Mitigation Braking System camera failure indictions appeared in the dashboard control center. I took the vehicle to the Honda dealership who stated there is not an active recall and that this was not a covered expense. Out of caution because I have read of the system failues causing brake lock-up related to over 40 vehicular crashes and almost twice that number of injuries, I decided to immediately obtain this $2,000 repair. I contact Honda of America to start a claim for a goodwill reimbursement and they told me only (and repeatedly) that the vehicle was too old, out of warranty and that they WOULD NOT consider reimbursement of the repair to this integrated and vital safety system. the federal safety agency has documented 2,976 complaints involving unintended automatic braking in Honda vehicles, with 47 crashes and 93 injuries reported. These issues involve Honda vehicles equipped with camera-based collision mitigation braking systems similar to the one used in the 2017 Pilot. Because this failure involves a core safety system component, and because there is: -documented evidence of system-wide safety investigations -thousands of consumer complaints -shared safety technology across the Honda lineup I requested reimbursement from Honda America. They made ZERO effort to acknowledge this safety system fault and clearly stated they would not reimburse me NOR would the customer service representative provide me with any guidance on how to further pursue the matter. the federal safety agency complaints involving the 2017 Honda Pilot reference failures involving the Collision Mitigation Braking System, Lane Keeping Assist System, and Adaptive Cruise Control warnings, all systems dependent on the same forward-facing camera architecture. Front multipurpose camera replacement was the final repair needed and NOT reimbursed.
2017 Honda Pilot Errors: lane keeping assist problem LKAS adaptive cruise control problem ACC road departure mitigation system problem RDM collision mitigation system problem CMBS or Collision Mitigation Braking System
Multiple lights, for ACC, Lane Departure, Forward Collision Warning, and Lane Keeping Assistance system. None of the systems works. Safety of myself and others put at risk due to systems not working and preventing collision. The problem was confirmed by the dealer. Multipurpose camera not operating, required replacement of camera for systems to operate.
so i have a Honda pilot and have been seeing a light saying that my collision mitigation system is broke so i took it in for a diagnostic which i was charged for which is fine and normal i guess but they told me that the system was broken possibly from just driving through construction zones and this causes phantom braking so i have to get it fixed but they want to charge me for the repairs which from my perspective the customer i shouldn't have to pay for a defect like that that can cause injurie or much worse
ACC, LKAS, collision avoidance, and other safety features lights all came on at once.
The contact owns a 2017 Honda Pilot. The contact stated that after coming to a complete stop, the Auto START/STOP feature was activated, but the engine failed to restart after releasing the brake pedal. Additionally, the transmission intermittently shifted to neutral(N) or park(P) while at a complete stop. The Collision Mitigation Braking System warning light was illuminated. The contact depressed the brake pedal and shifted the transmission to drive(D), allowing the vehicle to respond. The vehicle was taken to an independent mechanic and the dealer; however, the cause of the failure could not be determined. The vehicle was not repaired. The contact related the failure to the federal safety agency Action Number: PE22005 (Engine and Engine Cooling). The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.
When Engine goes idle during the brief traffic stop, Collision mitigation warning shows on and goes off quickly, sometimes causes the engine to not turn on during the times. Problem is so intermittent and hard to track as it is random behaviour and comes on for milli seconds in terms of warning on the dash board.
During the last week, alerts would appear on my dash from the Collision Mitigation Braking System and Road Departure Mitigation System. These alerts will appear while driving at 30mph on a city street. When the alerts appear, the brakes are activated and the steering wheel locks up. The alerts immediately clear but it is very alarming to the driver and passengers. Yesterday while parallel parking, in the mist of reversing into the parking space, the systems triggered alerts along with a transmission alert. The system immediately put the vehicle into park and would not permit the change of gears. While halfway in the parking spot with the front of the vehicle sticking out into on coming traffic, I was forced to completely turn the vehicle off, wait about 3 minutes before turning it back on. This allowed me to complete parking the vehicle in the spot.
Over the past couple months, while driving the collision mitigation braking system would activate for no reason. As of 2 weeks ago, now my collision mitigation braking system does not work and on the dashboard display it shows collision mitigation system problem. I have read on multiple Honda boards and general internet search on this issue, many people are having the same issue. This issue has been affecting people for maybe 5 years. I’m wondering why this is not a safety recall for the Honda vehicles.
