Lane departure, Forward collision avoidance, Sep 27, 2026
One morning, with no prior issues, we started driving our van and it suddenly displayed several warning lights, including brake system, adaptive cruise control, auto emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. We took it to Darcars Honda in Bowie, MD who diagnosed it as a front facing camera failure. The dealer replaced the camera and kept the old one. This failure in a six year old van increased the danger of collision while operating the vehicle.

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.

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

Safety mitigation compoments failure that started as intermitent issues and now is consistent. Warning lights come on for Adaptive cruise control failure, Forward collision failure, Lane departure warning failure, high beam failure, lane keep assist failure and others all link back to the DTC U3000-49 internal multipurpose camera unit failure. This compenet failure puts all oppcpants and other vehicles at risk as driver have become reliant on all feature working properly to enhance safety for all. The problem has been diagnose and inspected by two different dealerships. No accident or vehicle comprimised, the camera component just fails and have talked to two other familes that have had same issue. The issues started as a inteitent flsh of all the warning lights and that moved to a constant issue. Currently you can drive the vehicle for a various amount of time and eventually the lights will go on or the dash will be lit up like a christmas tree as soon as you turn it on. Concerned as this is a vehicle that a majority of Moms and kids drive in, as is the case for our familiy.

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.

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.

I am the original owner of a 2020 Honda Odyssey Elite. On July 7, 2026, at approximately 76,127 miles, five safety-system warning messages suddenly appeared simultaneously upon startup: Adaptive Cruise Control Problem, Auto High Beam Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, and Lane Keeping Assist System Problem. Restarting the vehicle several times did not clear the warnings. After the vehicle sat for approximately 30 minutes, the warnings disappeared. On July 8, after driving approximately 400 miles home, I parked the vehicle outside in approximately 110-degree heat. About two hours later, upon startup, the same five warnings reappeared simultaneously, along with the Brake System warning light. An authorized Honda dealer confirmed the multiple warnings and performed a DTC scan. Code U3000-49 was stored, indicating an internal failure of the multipurpose camera located behind the rearview mirror. Further testing confirmed that camera replacement was required. The dealer replaced and recalibrated the multipurpose camera at 76,567 miles. The repair cost was $1,631.80 for parts and $717.50 for labor, totaling $2,349.30. I am concerned that failure of a single internal camera component simultaneously disabled multiple driver-assistance and collision-avoidance safety systems. I believe NHTSA should investigate whether multipurpose camera failures associated with DTC U3000-49 represent a recurring safety defect in 2020 Honda Odyssey vehicles.
Forward collision avoidance, Jul 8, 2026
The front-facing Honda Sensing camera in my 2020 Honda Odyssey overheated in a 90deg climate. This triggered multiple dashboard warning lights: Adaptive Cruise Control (ACC) Problem, Lane Keeping Assist System (LKAS) Problem, Road Departure Mitigation (RDM) System Problem, Collision Mitigation Braking System (CMBS) Problem, BRAKE System Problem, and Auto High-Beam Problem. The Honda dealership quoted me $1850 to fix it and they said it was a well-known error. There were NO issues with my car prior to this problem. I keep up with all routine maintenance, oil changes, timing belt and water pump replacements, etc. Not only are these safety features inoperable, but these warning lights are very distracting to the driver, but worse than that- I would be unaware of other system failures since I have so many warnings displayed.
