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.

Water is leaking through back tailgate every time it rains. Water pools on the back floor and gets into the tailgate control unit. As a result, mold has grown on the floors and water has gotten into the power tailgate control unit causing my tailgate to stop opening and propping up (I have to manually hold the heavy door while lifting items out). This has caused electrical problems with cruise control and several lights blinking on and off my dashboard throughout the duration while driving. I have had the engine and transmission all tested and everything is working properly in that regard. The conclusion is that these electrical malfunctions are due to water damage. I have already had the control unit replaced once a year ago.

When I turned on the ignition to drive the vehicle, multiple warning lights came on to include failure of lane keeping assistance, forward collision avoidance, adaptive cruise control, lane departure warning, and automatic emergency braking. Additionally, after acknowledging these lights, the "brake system" light remained on in the amber color. If these safety features are not working properly, it can put the occupants of my vehicle as well as others at risk.

In May 2025, the front-facing windshield-mounted monocular multi-purpose camera unit abruptly failed in our 2018 Honda Odyssey Elite. The vehicle had ~53,000 miles on the odometer at the time. This resulted in essentially all of the warning lights showing/cycling on the dashboard display and total failure of the safety features dependent on this camera system (adaptive cruise control, forward collision warning, automatic emergency, lane departure warning, lane keeping assistance, etc). The unit had to be completely replaced and calibrated by my local Honda dealer.

One week ago, I was driving on a highway, accelerating to the 65 MPH speed limit on that road, my van's accelerator completely stopped responding. Despite pumping the pedal repeatedly, I was unable to control my speed at all, and the car continued to lose speed. I had my three children in the car at the time, and given that people regularly go in excess of 70 MPH on that road, I was in danger of not being able to exit the road and/or being hit. I was able to coast off of onto an exit, and the car started responding at speeds of 30 MPH, but it was lurching and jerking while driving. We immediately had the vehicle inspected by an independent mechanic and have been advised that the transmission needs to be replaced. There were no warning lights for this failure. The car also had an incident about a year ago where all lights came on and it stopped responding. At that time, we had Honda dealership examine it, and they said they could not find any issues. Additionally, the car has been jerking slightly while shifting, but the issue improved when we had the transmission fluid flushed at the Honda dealership again about a month ago, and no issues were noted by them at that time. We have performed regular maintenance and safety inspections on this vehicle.
