2010 Honda Odyssey

I am reporting a recurring and dangerous brake system failure in my 2010 Honda Odyssey. Intermittently, when the vehicle is first started, the brake pedal becomes completely stiff and cannot be depressed at all. During these events, the brakes are effectively non-functional until the condition resolves, creating a serious safety hazard. This issue occurs without warning and has happened on multiple occasions. This defect is especially dangerous because it prevents normal braking operation at startup, increasing the risk of a collision if the vehicle is moved or if immediate braking is required. I have attempted to repair this issue extensively. The vehicle has been inspected by three separate repair facilities, including a Honda dealership. The following components have been replaced in an effort to resolve the problem: •Master cylinder •Brake booster •Rotors •Brake lines •ABS system Despite these repairs, the issue persists unchanged. I have spent over $2,500 attempting to fix what appears to be a systemic defect. The Honda dealership suggested the issue may be caused by air entering the brake lines when the vehicle is parked on a slope. However, this explanation is not consistent with normal automotive function, and similar vehicles do not exhibit this behavior under the same conditions. Given the repeated failure of major brake system components to resolve the issue, I believe this represents a defect in the vehicle’s braking system that could affect other vehicles of the same model. I am submitting this complaint due to the serious safety risk posed by intermittent loss of braking function and request that this issue be investigated.

A few years ago the driver's side rear sliding door stopped working. This seemed like a safety because, if there were ever an incident such as a fire, people would not be able to expeditiously exit the back two rows of the van. There were no warnings, the door just stopped working. I spoke with our mechanic about it and he stated that he had seen that with several Honda Odyssey vans. I had the door repaired. I recently learned that this had been an issue with other Honda Odyssey vans and wanted to let you know it had also happened to me.

When having to slow down or stop quickly, the van starts to jerk back and forth and shake a lot and the car becomes very difficult to control. This is especially noticeable when going down hills such as I-70 in Colorado, I-15 in eastern California or mountain passes in the Sierra Nevadas, but also when coming around a corner on a freeway and the traffic is stopped. It would be very serious if driving and a child ran out into the street in front of the van. I recently learned that this has happened fairly frequently with Honda Odyssey vans. I have had to replace brake and strut parts and bearings multiple times. (gratefully the struts were still under warranty, so I only had to pay for labor the ensuing times.)

A few months ago, the battery went dead. I purchased a new battery and it went dead also. I had the mechanic check it and he said that some Honda Odyssey's had that problem (usually 2011). Even if everything is turned off, the battery will die in less than two days if the van is not driven. This has led to the van being inoperable in various locations requiring a locksmith to come open the car so the hood can be opened so the the battery can be recharged. The mechanic spent a few hours and was able to pinpoint the "faulty" fuse(Driver's side, #7, 7.5A, "backup"), but said that there were 13 different subsystems associated with that fuse and that it would take many hours to isolate and test each individual subsystem which would cost many thousands of dollars--more than the car is considered to be worth. So he recommended that I just either drive it every day or pull the fuse at night. In addition to the battery going dead, one of the problems, is that I don't feel safe to lock the car because I know I won't be able to unlock it if the battery dies.

The driver's side & passanger side rear sliding doors develop a parasitic battery drain which forces owners to remove the fuse associated with the doors. Those doors are very difficult to open when not powered. This essentially traps children in the back seats. Honda knows about this issue with all the odyssey models and they have not issued a recall.

The fuel pump as been failing and caused issues

See attached document for complaint.

For the second time in less than 4 months my rear window has exploded into thousands of pieces. The broken bits explode everywhere. First time was 1.15.25. Second time was 5.3.25.I was parked both times. I had other windows/doors either cracked or open. Both times was during 20mph winds.

The contact owns a 2010 Honda Odyssey. The contact stated while driving or parked, there was a strong fuel odor coming from the vehicle. The vehicle was driven to the dealer where it was diagnosed and determined that the fuel pump and the fuel tank needed to be replaced due to a leak in the fuel tank. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was 66,000.

The incidents of sudden acceleration while braking on this model are vast. My van has experienced several sudden un-commanded acceleration incidents while braking starting in 2022. Honda lawyers are in control and thus no technical explanation. My last event was on [XXX] post hurricane Helene in Asheville N.C. The response of the NHTSA is needed due to people of modest means need to keep their car as long as possible. This requires honest service information from Honda. Honda has reaped a well deserved dividend cultivating the belief that their product with careful use can last 20 years or more. Honda does not deserve to reap this benefit while failing to execute an honest service which creates an unsafe vehicle. In 2023 the Throttle Position Sensor and its complete assembly was replaced in hope of a resolution. I will now replace the Engine Control CPU after the [XXX] incident. These repairs and expense are un-diagnosed non-OBD supported “shots in the dark” because Honda will not recognize the failure.

It started with the alarm turning on randomly. DRL not turning off and battery got drained.

Honda service bulletin [XXX] I recently discovered after doing some research on why my 2010 Odyssey is showing cylinder1 misfire code. I replaced the injectors, swapped coil packs, etc. Still cylinder1 misfire issue. Now I find out that Honda is aware of this issue and related to VCM and some rings on piston(s) aligning. Fortunately for Honda, the 8 years unlimited miles is most likely out of a window where statistically the issue will be seen. That is my case. Sept 25, 2021 is when this first started, and has continued to be an issue. I never received notice from Honda since this is a used van. Anyway, I would like some assistance in rectifying this issue for our family van. My local Honda dealer is not even remotely interested in repairing the issue based on [XXX] because of the 8 year extended warranty is no longer applicable. I need help from Honda NA. If you know there is an issue with ring alignment, extending this for 8 years doesn't seem like you are capturing the majority of the problems; most likely a calculated risk... My Odyssey didn't show the issue until 11 years after the 2010 manufacturing date... fortunate for Honda. I need help from Honda on this, even to meet me 1/2 way to cover repair costs. This seems unacceptable to me that an issue as serious as this, known by Honda, and won't be addressed. Please help. Thank you, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Passenger side sliding door jammed halfway open and would not close or open. Had to have the car towed to the mechanic and have all components of sliding door replaced (twice!). Driver's side strut spring broke under normal use - with 62000 miles on the vehicle. Now rear backup camera/GPS/radio unit has ceased working at all. Passenger side door also randomly begins to close part way through opening, nearly injuring my child's friend who was exiting the vehicle.

Yesterday(7/9/23) when trying to open and close our back sliding door on the drivers side it was making a louder grinding sound and was difficult to open/shut. No warning lights. Today when pushing the button to open the door it started to open and then fell off the frame on the top and mid rail. Only connected by the bottom rail. It appears that the mid rail/ slider is the part that failed causing the door to come off its hinges. It also caused large deep scratches to the body of the car. This is a serious safety concern. The door is heavy and could have hurt someone. We are very lucky that my kids were still strapped safely in their car seats. We strapped the door to the car in an open position and have not gotten it inspected yet. Upon researching I have now seen hundreds of reports of this same thing happening to others.

The contact owned a 2010 Honda Odyssey. The contact stated while driving approximately 55 MPH the vehicle began to vibrate and there was an odor of burning coming from the rear. The contact stated that she saw a "red glow" coming from the rear seat. The contact pulled the vehicle over and stopped, as the contact exited the vehicle it burst into flames. The contact stated that she did not notice any warning lights. The contact stated that the police and fire department arrived on the scene. The contact stated that water and chemicals were used by the fire department to extinguish the fire. The police wrote a report and the vehicle was towed to an impound lot. The contact stated that her insurance provider had declared the vehicle a total loss. The contact related the fire to recent recall work that had been performed for NHTSA Campaign Number: 14V112000 (Fuel System, Gasoline). The manufacturer had not been informed of the failure. The failure mileage was 145,623.

Power sliding doors stopped working. No access to middle row seats due to having no manual opening features. In an emergency, I would be unable to remove my children from their seats. This should be recalled immediately before someone becomes trapped in this car.

Van sliding door fell off when trying to close the door.

The driver side passenger sliding automatic door stopped working. When opening it manually I started hearing a little grinding noise and it was hard to open. I opened the door to put my daughter in and the door fell off to the ground.

DEATH TRAP Front windows open and close by themselves while driving - dangerous for kids and pets in car Sliding doors on both sides do not work properly - do not latch - passenger door doesn't slide open or closed Door locks unresponsive - last week only driver's door and tail gate would unlock and open

I opened the sliding door for my 5 yr old grandson, and while he was getting in the sliding door Opened and shut while he was getting in an almost closed him in by squeezed him alil I had to push the button instantly to open back up.an it happened when we was at the zoo also it Opened half way an was closing on its own
