2020 Honda Odyssey driver assist problems

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc.I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

​I am writing to issue a formal complaint regarding gross negligence, logistics failures, and deceptive service practices surrounding mandatory recall work on my 2020 Honda Odyssey. ​1. Failure to Complete Recall Software Work After Overnight Retention On Tuesday, September 1, your service department texted stating: "the software update did not finish. We do need it overnight." We agreed to leave the vehicle. However, upon pickup, the infotainment display confirmed that the update was never completed and remains stuck at Step 5/6 (System Update 24084.7 / Front Control Box B.1.4.6). Retaining a customer's vehicle overnight under the guise of completing software work and returning it unfinished is a direct misrepresentation of labor performed. ​2. Extreme Logistics Failure and Disregard for Customer Time At 12:55 PM on Wednesday, September 2, your department texted: "Ready to go now!" My wife arrived promptly, yet your staff forced her to wait until 2:40 PM—nearly two hours later—before physically releasing the car. This gross delay caused her to miss our children’s school pickup, forcing me to leave my workplace unexpectedly to handle child transportation due to your operational incompetence. ​3. Cascading Network Faults and Critical Safety Systems Disabled Prior to service, the dashboard displayed minor Sensing suite warnings, for which your department quoted an exorbitant $250 diagnostic fee. Upon picking up the vehicle, the dashboard warning count escalated from 5 to approximately 9 active system failures. Due to the interrupted ECU software installation corrupting the CAN-BUS network, the following primary vehicle controls are now completely inoperable: ​Supplemental Restraint System (SRS / Airbag) (Newly triggered post-service) ​Vehicle Stability Assist (VSA) System ​Automatic Brake Hold System ​Electric Parking Brake (EPB) System ​Electric Power Steering (EPS) ​Hill Start Assist ​Honda Sensing Suite (Lane Departure, Collision Mitigation, Road Departure) ​Releas

FORWARD COLLISION AVOIDANCE

The contact owns a 2020 Honda Odyssey. The contact stated that the Traction Control, Adaptive Cruise Control, Lane Keeping Assist System, and Road Departure Mitigation warning lights illuminated. The vehicle was taken to a dealer, where the cause of the failure could not be determined. The contact continued to drive the vehicle as it passed state inspection. While driving approximately 65-70 MPH, the cruise control suddenly failed, requiring the contact to manually steer the vehicle. Additionally, the Collision Mitigation Braking System, battery, and ABS warning lights illuminated. The contact stated that the ABS light illuminated after the brake pads were recently replaced, and the ADAS calibration was not performed. The vehicle was taken back to a dealer, who informed the contact that the monocular camera burned out due to windshield brackets; however, the contact stated the failures occurred prior to the windshield replacement. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

2020 Odyssey Elite multipurpose camera unit internal electronic failure DTC U3000-49. Component is still installed and available for inspection upon request. Failure disabled Honda Sensing safety systems: Adaptive Cruise Control, Lane Keeping Assist, Lane Departure Warning, Forward Collision Warning, Collision Mitigation Braking, Road Departure Mitigation, Automatic Emergency Braking, and Auto High-Beam. Dash showed Honda Sensing system failure warnings. No crash, no injury. Vehicle remains drivable but without active safety features, increasing risk of crash, especially on highway. Dealer confirmed failure and reproduced it, recommended camera replacement plus ADAS static/dynamic calibration, quoted $2,243. No prior symptoms, no accident, no damage, well-maintained. First warnings appeared Aug 2026 and stayed on continuously. Manufacturer was notified and denied goodwill coverage, stated out of warranty. This is a known widespread defect — same U3000-49 failure documented in NHTSA complaints 11615376, 11584269, 11603801 for 2018-2020 Odyssey, Art's Automotive public statement on pattern, YouTube coverage 2016-2021, and eBay repair market with one seller showing 485 repairs for this exact camera and 111 watchers.

I went to the dealership today for my recall on the backup camera where my screen goes black in reverse. I also told me my dash lights had come on and could like lane keeping assistance, adaptive cruise control and blind spot warning. Dealership then tells me it is a faulty internal camera in the windshield and wants to charge me $2K. Is this not a recall since it happens to a significant amount of honda odysseys and pilots? Please make this a recall as it is not safe to drive my van anymore and should be apart of the recall I took it in for.

The electrical component is failing. I have brought in this vehicle 2 times for failed electrical issues over several years (around 2 years), and it only has 52,000 miles currently. The back up sensors no longer work, as well as warning lights for the following began to appear a year ago: collision mitigation, adaptive cruise control, lane keeping assist, road departure mitigation. Sometimes, our electrical side door will not close and will keep opening when trying to shut. This electrical issues has been draining our battery, and while driving, my car shut off in the middle of the street while I was waiting for a light. After a few attempts, I got my car started again. We replaced the battery, and a few days later the car would randomly turn on and I could not use an electrical key to open the car door. Only way to open it is with the physical key. The battery had to be unplugged in order to stop the car for randomly turning on. All electrical systems would turn on in the car, including the alarm and radio, even if the radio had been off when the car was last turned off. The car has been inspected by Honda mechanics, who told me the electrical component is dying, but they don't know why, the car isn't that old, and it has very few miles on it.
