2020 Honda Fit Driver assistance Problems

The Adaptive Cruise Control (ACC) system and multipurpose camera unit (part of Honda Sensing) on my 2020 Honda Fit malfunction intermittently. On some engine starts the camera and ACC function normally. On other starts the camera does not work at all and ACC is completely unavailable. The vehicle and the camera/related components remain available for inspection upon request. When the multipurpose camera fails at startup, Adaptive Cruise Control and associated Honda Sensing features are completely unavailable. This removes automatic distance control, forward collision warning, and related driver-assistance functions, creating an increased risk of collision, especially during highway driving or in traffic where those systems are relied upon for maintaining safe following distance and providing warnings. It is easy to reproduce. Sundevil auto sees it when servicing my car. I have spoken with many Honda dealers in the Phoenix AZ area and they all say that it happens a lot and that the only solution is to replace it. The failure is intermittent and occurs only on certain engine starts. On the starts when the system fails, the multipurpose camera does not function at all and Adaptive Cruise Control is unavailable. On other starts the camera and ACC work normally. No consistent prior warning lamps or messages beyond the complete non-function of the camera and ACC on the affected starts have been noted.

This 2020 Honda Fit has experienced a "multipurpose camera unit/millimeter wave radar internal electronic failure" that will cost $2,000 to repair. Neither Honda nor my auto dealership will help me and insist it isn't under any kind of warranty or covered by a recall.

-The multi-purpose camera sensor system on my 2020 Honda Fit EX Hatchback has malfunctioned, disabling critical safety features such as Adaptive Cruise Control (ACC), Lane Keep Assist System (LKAS), and Collision Braking Warning System (CBWS). -The failure of these systems creates significant safety risks. Without ACC, the vehicle cannot maintain a safe distance from other vehicles. The LKAS no longer provides steering assistance to help stay in the lane, and the CBWS cannot detect or warn of potential collisions. These malfunctions increase the likelihood of accidents, especially during highway driving or in heavy traffic. -The issue has been reproduced and confirmed by Tony Honda in HI during an inspection on [XXX]. -My 2020 Honda Fit EX Hatchback has been inspected by an authorized dealer/service center, which diagnosed a failure in the multipurpose camera. This failure has disabled critical safety features, creating a potential safety risk. The vehicle has less than 21,000 miles and has been well maintained. However, the manufacturer has not offered a resolution, and the vehicle has not been inspected by police, insurance representatives, or other parties. Despite the low mileage and the importance of this system, I was informed that I must pay the full repair cost of $3,000 and other companies I visited stated that it can only be fixed by Honda. I believe this issue could indicate a defect and request an investigation into whether other Honda Fit owners are experiencing the same problem. -Before the failure, warning messages appeared on the dashboard, including alerts for ACC, LKAS, and CBWS system malfunctions. These warnings initially appeared for a week or so and became more frequent over time. I believe this issue may be a design or manufacturing defect affecting other vehicles of the same make and model. I urge the NHTSA to investigate this matter to determine if it represents a broader safety concern. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Multiple warning light up on dash and loud beeping upon start up. No way to remove warnings which distract. Multiple safety features disabled 95% of time and the randomly work fine 5% of the time. Not related to any obvious damage or incident. Got in car one day to find several warnings and loud beeps. Acc, lkas, road diparture mitigation, collision mitigation, and auto high beams all out. Warning light for each, plus a brake system light.

Automatic emergency brake bleeps warning and brakes get locked while driving. This happens all the the without any objects nearby or vehicles close enough to initiate the emergency brake. Emergency brake engages and locks itself in normal driving conditions. This has happened multiple times, and put the driver in serious hazard in busy traffic.

The Collision Mitigation Braking System (CMBS) consistently provides a false positive when approaching a particular railroad crossing near my home. When about 20 yards away from the crossing (a single set of tracks) approaching at 30-35mph, the BRAKE warning flashes and beeps for a second or two, but it's not clear that any actual braking is applied. This does not happen if I slow to about 20mph or less before approaching the crossing. At this particular railroad crossing, the road is going downhill towards the tracks and the tracks cross the road at 90degrees. This happens day or night (there are street lights at this crossing). The forward collision warning distance is set to Normal. At other railroad crossings where the road is level or going uphill towards the tracks, I have not experienced this issue.

Forward emergency collision detect system went off randomly and slammed on brakes. No cars or objects were in front of the car. Was going 30mph. Car hit brakes so hard that abs engaged. Almost got rear ended. After car nearly came to stop, returned to normal driving.
