2018 Honda Odyssey: engine overheating

Filed Aug 31, 2026 · Driver assistance, Electrical · UT

The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.

Our van recently started flashing multiple warning lights every time we started it up. These include "Collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the ADAS camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.

Back in the fall/winner of 2024 (could have been 2025) my Honda Odyssey had a recall for a low pressure fuel pump. However, Honda and many other dealers were dealing with hundreds of thousands of recalls, and we’re only recalling the vehicles with actual symptoms. My vehicle was hesitating and experiencing sudden loss of power during acceleration therefore Honda agreed to repair my vehicle. Everything seemed to work fine after that with no issues, but approximately three months later, I was having issues with my vehicle and brought it into my Mechanic, to find out that my high-pressure fuel pump was not working properly. Upon further investigation, I found out that a bad low-pressure fuel pump starves the high-pressure fuel pump (HPFP) of required volume. This causes the HPFP to work far beyond its design limits to build pressure, leading to cavitation (vapor bubbles damaging internal components), overheating, and premature mechanical wear from metal-on-metal friction. When I dug a little deeper, I found out that many Honda owners were dealing with failing high-pressure fuel pumps after having their low pressure fuel pump recall repairs completed. Many in which were in a similar timeframe to mine. Honda offered me no good merit assistance and stated that unfortunately, I would be liable for the entire cost of the repair. It is more than obvious that the failing of my low pressure fuel pump impacted the performance and workload of my high-pressure fuel pump, causing it to fail, which I believe Honda should be liable for replacing. Please look further into this matter to help others like me that had their low pressure fuel pump recall performed, and shortly after needed to replace their high-pressure fuel pump at their own costly expense.

Multiple dash lights warnings (LKAS, forward collision, lane departure, etc.) came up. Brought it to the dealership and was told that this is an electrical camera issue that is overheating, and there is no preventative or ways to keep it from happening. It would cost an upward of $2000 to fix it. This should be part of the recall since it seems like it’s happened quite frequently with the other Honda Odyssey.

Failure of the Front windshield mounted monocular camera from overheating causes all advanced driver assistance systems to shut down such as automatic emergency braking, adaptive cruise control, lane assist, etc. This is a very common occurrence in not just the Honda Odyssey, but other Honda models as well. A new part can be anywhere from one to two thousand requiring dealer calibration. The heat from the sun, the location of the monocular camera and possible contribution from replaced non-OEM windshields may contribute to the overheating. With all safety devices disabled, the vehicle becomes unsafe to operate requiring immediate attention and dealer only service since a new device requires calibration.
