Warnings problems of the 2019 Honda Odyssey - part 2

On January 18, 2024 I had the following recalls performed on 2019 Honda Odyssey elite: auto idle stop and the media oriented systems transport (most) communication coaxial cable. Immediately after the recall work was completed, I began receiving an error code "collision mitigation system problem". The error code would flash after this sequence of events: after my car's engine has come to temperature and is warm. I come to a complete stop, my car goes into idle stop and when I release the brake to accelerate and the engine re-engages, this error flashes. And, I can continue to drive. Prior to this recall work, I had never received this error. In addition to this error code, on January 24, 2024, I was at a complete stop on a freeway offramp. When I released the brake and tried to accelerate, my car would not engage and very loud clunk, followed by the orange "brake system" light flashed on. Eventually my car engaged and we were able to drive. The clunk was so loud my teenage children asked me if we were hit by another car. On, Friday January 25, 2024 after dropping the car off at the dealership we were told that "the diagnostics have revealed a 'defective multipurpose camera and aim'. And, the cost to replace is $1793. 77 plus tax.

The van suddenly started randomly throwing up a series of 5 different codes, all relating to the forward camera system. It will appear and disappear at random, showing lane keeping assist, forward collision system, adaptive cruise control, automatic dimming headlights and lane departure system failed. There are tons of issues with the car having bad cables/terminals for the rear camera, a/v systems, and sxm antenna, but Honda refuses to admit that the front camera issue is related.

There has been no incident. And I hope there is not. But the forward camera that assists in the road departure mitigation, forward collision mitigation and lane keeping assist has failed. Also inoperative is the cruise control, auto dimming headlamps and the brake system light is on. I find it hard to believe that after some of the less critical recalls that have been sent out for this vehicle that they don’t address this very important safety system. The camera alone costs $800 and that doesn’t include the cost of installation and calibration. I have a family of six and we use this van extensively. But we cannot afford this repair and are forced to drive with all of these lights on in the instruments. We take extremely good care of our vehicles. It is serviced well and has been in no major accidents. Please help us get action for ourselves and others who are in danger.

Over 20 times our van has breaked when it was not needed. This usually happens when going up a hill and turning, or when a car slows but not enough to need to break. In several instances we have almost been rear-ended due to the sudden breaking. We try to turn off the service, but it has to be turned off each time. With the amount of traffic we have in the area, this is very dangerous.

The multipurpose camera in the front windshield has failed, causing the adaptive cruise control, lane departure warning and correction, forward collision to fail. Even the non-acc cruise control is locked out due to the failed camera. Honda will charge ~ $1800 to replace, and I can’t afford that. Problem confirmed by ian’s of broken arrow. They confirmed it was the camera and not the radar unit. The failure of the camera causes a host of persistent dashboard warnings, but none preceded the failure.

There was no warning display on car today during the incidents. I pressed the breaks and with my foot on the breaks the car accelerates 3 times. I had a car in front of me which is why I stopped but no no one behind me to trigger the car to propel me forward 3 times despite my foot on the brakes. This is second time it does this. I took it in right away to the shop. The first time was a a couple of months before (may 2023) but I had a car behind me so I figured the car took over to avoid a bump in back…but again my foot was on the brakes. And I had a car in front and in back, which could have caused an accident in front. Weird acceleration all the time: when you are at a stop and try to accelerate, the car stalls and then accelerates abruptly. Very dangerous when you have drivers behind you and in front. Collision mitigation warnings keep popping up since 2022, but shop could not see the issue because the display disappears. It pops up randomly and disappears.

I have a cmbs issue. Nothing around that would trigger it just driving through an intersection and the cmbs came on and basically just stopped the car for no reason. I get these "brake" messages mostly when the car in front of me is turning right and the Odyssey doesn't think I slow down enough. I know the car is turning, the Odyssey doesn't. I've also had it come up a couple times while going around a curve, I think it detected the oncoming traffic as being in my lane and it told me to "brake". I have video files to prove from my dash cams but I could not upload these files here. Honda dealer misdiagnosed to replace power distribution module but it did not fixed and I found other Honda vehicles has the same cmbs issue. Hoping you got some resolution. Thanks.

In September 2021, I started occasionally receiving the error message "collision mitigation system problem" on my dashboard. It would appear and quickly disappear. At that time, my car shut itself off when I came to a full stop at traffic lights and stop signs 3 different times. The car would boot back up, but it happened to me in the middle of intersections. I took the vehicle into the dealership and they told me it was the battery. I had the battery replaced, but with time, the "collision mitigation system" error reappeared along with other messages, "engine management system problem" and "road departure mitigation problem. " during this time, my car would brake on its own occasionally, happening 6 times in total, when there was no threat of a head-on collision. Three of these incidents happened in the middle of intersections with cars all around me and in one instance, my car come to a screeching halt on its own making me terrified that the car behind me was going to crash into me. The last straw was as I was driving to my child's school and when I came to a curve in the road, my steering locked up completely, not allowing me to turn with the curve. I was able to slam on my brakes and keep myself from crashing, but it was very dangerous. At the same time, the same error messages were flooding my dashboard. That is when I drove my just 3 year old car back into the Honda dealership and told them they must fix this before I put my child back into that car, and my car still sits there. The dealership informed me that my collision assistance camera that is integral to the Honda sensing safety mechanisms is "faulty" and will cost me $1,500-$1,700 to repair. I see online that this is being investigated in 2017-2019 Honda crvs and 2018-2019 Honda accords sedans. I implore you to also investigate this same system error in 2019 Honda Odysseys. The Odyssey is a family car, but yet I am now scared to drive my family in this vehicle for fear of it causing a collision.

Over the years of owning this vehicle, we've encountered sporadic electrical problems that have led to the car either stalling or needing a jump start. Despite these issues, inspections of the battery have revealed no obvious problems. Additionally, we've had intermittent system warning messages for features such as adaptive cruise control, forward collision warning, and lane departure. These warnings have surfaced and vanished on multiple occasions. The vehicle has never been in an accident or experienced anything beyond normal operating conditions.

Going 25mph. Steering wheel shook then dash read in black "brake" with orange background. Van braked on its own. Nearest car was 75 feet away.

There are 2 issues, possibly related. First of all, warning for collision mitigation system problem appeared and then the digital display went blank. The steering wheel shook violently. In the second problem that occurred, a warning light flashed on and off (too quickly to determine what it said) and then the car went into neutral on it's own. The car was in motion in both occurrences.
