Adaptive cruise control problems by model year
What owners say
Over the course of 3 days, cruise control and lane assist systems would shut off and messages would display about adaptive cruise control, lane keep assist, lane departure warning, and collision avoidance system not working. Sometimes a transmission problem message would also become active. Sometimes the messages would be present at startup but other times the systems would show up green on the display and then the systems would shut off while driving causing the vehicle to suddenly slow down in highway traffic. The root issue seems to be a broken or malfunctioning multipurpose camera for the driver assist system. The camera has not been replaced yet to verify but related codes are active based on a code scanner and symptoms match what is expected for the camera failure. The vehicle is 6 years old with 99,400 miles at the first occurrence of the issue and does not have any windshield damage or signs of water leaking that would contribute to a failure. My primary concern is that the software completely disables cruise control when the camera for adaptive cruise and lane keep assist fails causing the vehicle to suddenly slow down rather than allow normal cruise control to continue operating and display the warning messages.
On the middle of July, we were driving and all of a sudden all these lights start coming up the Brake System Warning, Collision Mitigation ,Adaptive Cruise Control (ACC) , Lane Keeping Assist System (LKAS), Road Departure Mitigation System, Auto High-Beam we took it to holler Honda. They said that it was code u3000–49 for forward camera and that it will need to be replaced. They are charging us almost $3000 to get it fixed.
Front Camera failure which disables the entire Honda sensing Suite, Shuts down Cruise control, lane keeping assist, front collision warning and Auto emergency braking. This has caused the loss of many safety features intended to prevent accidents and injury. There are numerous warning lights on the dash that are constantly displayed and can be a distraction to other safety or maintenance concerns. Dealer has diagnosed the problem to be an issue with a faulty front camera system. The repair for this is extremely expensive
Upon starting my Honda Odyssey, the dash immediately started saying, Collision Mitigation System Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Lane Keeping Assist Problem, Auto High Beam Problem.
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.
Front windshield mounted sensor failure on 2020 Honda Odyssey. Disabled Honda Sensing safety suite which included lane keep assist, adaptative cruise control, auto high beams which all triggered warning messages on the dashboard which all occurred at the exact same time. This problem has been reproduced an inspected by Honda of Frontenac.
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.
