Prior to purchasing this vehicle, On the test drive, the vehicle slammed on the brakes for no good reason. The dealer assured me the collision mitigation braking system (-??CMBS-??) can be turned off, so I bought the car. I then learned that the CMBS automatically turns on every time the engine is turned on. I must shut CMBS off each and every time I start the car, but since my other car is a Tesla (which doesn-??t have this problem), sometimes I do forget to shut off CMBS. Through out my almost 7 years of ownership, the car has slammed on the brakes COUNTLESS numbers of times for absolutely no reason at all. Sometimes no cars are behind me, but there have been several times when cars behind me have almost crashed into me due to my faulty CMBS. My elderly mother is in need of a car and I refuse to let her borrow mine because I am scared she will forget to disable the CMBS and get into a crash. I am deeply astonished that with everything that is known about Honda-??s CMBS, NHTSA has not taken any action against this dangerous feature. I wonder what NHTSA is getting paid to look the other way. A complete failure of an institution I used to hold in high regard.

Soft or Low Brake Pedal The brake pedal have a soft feeling and travel to the floor with low effort. This is causing low braking performance and increased pedal stroke. This condition is increasing the risk of a crash.

2018 Honda Odyssey front camera failures. We bought it brand new and found out today that front multipurpose camera was not working properly. There are bunches of warning lights popped up on dashboard: LCC, LKAS-?? problems. I went to Google and Facebook to see there were so many people have the same problem particularly with this 2018 models. Dealership wanted $1800 to replace camera and they know that was Honda technical issues, not in customers control.

See service Honda Service Bulletin 20-100 Dated 2-11-2021.The fuel Injectors part Number 16010 (6EA) has failed and my dashboard display, displays most of the sensors that means there is an actual problem, or a false reading. As a Honda owner, I cannot determine if it is an actual fault or a false reading. I had Rusty Wallace Honda dealer check the car using OBD device and the equipment indicates a code 219A, which indicates bad fuel injectors. Now after the check additional and different sensors are displayed with problems than were displayed prior to this check. The trouble shooting and after displaying the code 219A indicated a catastrophic failure. Rusty Wallace has verbalized the results and that I should continue driving the vehicle, that this would not damage the engine or the car. I am not a certified mechanic, but my younger days were devoted to back street work repairing and driving vehicles. Anytime that you starve or flood a cyclinder you had serious problems. I need this vehicle as a daily driver.

Warning messages for the following appeared: brake system lane keeping/assist system collision mitigation system problem road departure mitigation system problem auto-high beam problem adaptive cruise control problem None of these safety features now work. Our local dealership told us it was a failure of the multipurpose camera unit. The fix we are told is a $1400 part. The rear camera was just recalled by Honda and repaired within the last month. This failure should not have happened and greatly impacts the safety of the car and it is a common problem when searching Honda message boards.

Just bought the car used with 60240 mi at the end of March on a Friday. 30 minutes after leaving the dealership the Auto Idle Stop warning notice appeared on the dash stating this feature was unavailable. It would not engage when idle at a light and as a result, when the gas was pressed to accelerate the car would hesitate and jerk into gear. This happened the entire 1.5-hour ride home, whether for a short pause or longer pause. It was a bit scary because the car would hesitate to move and clearly there were cars behind me. At any point and time, someone could've rear-ended me thinking I was able to accelerate properly. About 1 hour into the ride the brake lights came on flashing red at the bottom of the dash the entire time and would not go out. I immediately called the dealership once I reached my destination to announce the problem. The following Monday I took it back for a look over. In their investigation, they found a tracker attached under the dash and assumed this was interfering with the transmission of messages for the Auto Idle stop to engage. The dealer claimed there were codes, but after removing this attachment the auto idle stop feature engaged and they cleared all the codes. To my surprise, after 4-5 hours of being there, I drove home to find as I neared by destination all error codes returned including the brake lights flashing. I immediately called the dealer again and complained. This time to not further inconvenience me with the back and forth, they came and picked up the car on a Thursday with the intent of troubleshooting it over the course of some days. They had the car from a Thursday to the next Friday for me to arrive after them saying it was good, to find it was still doing it. This time the codes were reviewed with me in the car and the issue was "it was unlearned". After the reset, it started working again. Four days later it's still happening. Engages when it feels like it which causes a rough drive and acceleration. Honda help!

From the day I bought my car the brakes have squealed when applying them at a low rate of speed. There have been multiple times I have tried to accelerate and the gas took an extended time to work. Once I was trying to switch lanes and when I accelerated the van didn't go any faster and I almost caused an accident. The van shifts extremely hard. Everything the van shifts around 20-30 mph the entire vehicle jolts back and forth. This is a huge safety issue and the dealers will not acknowledge it. I have reached out to Honda's corporate number but they refuse to help. They have replaced the brakes, fluids and fuel injectors but all the issues still remain. I have also had a few issues with the sound system not working properly but have not mentioned that to the dealership or Honda corporate.

Electrical issues: After driving vehicle for 2 ' 5 minutes, entertainment system, rear entertainment screen and parking sensors stop working. The speakers make loud popping sound that will not go away even when you try to power off radio/entertainment system. Turning the vehicle off was the only way to stop the sound. Once restarted, everything would work for 2 ' 5 minutes and the same thing would happen. The speakers popping were very loud and distracting, screen with backup camera and parking sensors stopped working making the vehicle not drivable.

The front rotors warped and cause the steering wheels and front end of the car to shake whiling breaking at high speed. Shaking isn't noticeable under 30mph but the fast you go, the worst the shaking becomes. We had this issue with our older 2012 Odyssey and there was a recall for the it. When I ask the dealer about this issue, I was told there is no recall list for it and I will have to pay for replace my breaks and rotors.
