2012 HONDA ODYSSEY Complaints

vehicle loses acceleration power intermittently. No response when pressing accelerator or when speeding up with cruise control. Pressing the gas harder does not help but the vehicle starts working normally a few seconds later. Dangerous on busy roads. I don't think it is a weak fuel pump because it accelerated quickly after an event

The front valve cover is exposed to extreme temperatures from the catalytic converter mounted next to it. There is nothing to protect the rubber components inside from the catalytic converter's excessive heat which is causing them to fail. The steel components inside the cylinder (e.g., the seal ring) are insulated by these rubber components. When these rubber insulators fail, the steel components are exposed and make contact with the aluminum valve cover resulting in the galvanic corrosion of the aluminum. The most common result I have seen is the deformation of the area where the seal ring is seated (along with holes and cracks). Some people have also suggested possible defects in the casting of the aluminum as a contributing factor (the aluminum is also very thin in that area). Some have suggested the possibility of the uninsulated spark plug arcing, but it seems unlikely to generate enough heat to compromise the aluminum's integrity. The way people have described how the aluminum crumbles seems more indicative of corrosion. There are countless testimonies online of similar defects in Odysseys, Pilots, Accords, and Crosstours with the same engine. I have included a photograph of my damaged valve cover and those of others I have found online.

While driving on Thursday, 18 April 2024, the CHECK CHARGE SYSTEM alert and warning light came on in my 2012 Odyssey. I was able to get to a garage that was a few miles away, but the electrical system gave out about 1/4 mile from the garage. I was able to shift into neutral and coast into the parking lot. The dash lights were all off and the electrical system had stopped working. When I tried to exit the vehicle, I could not open the driver door. The lock was frozen in place and wouldn’t budge. I was able to pull the handle, but it did not unlatch or open the door. The power lock buttons did not work either. I tried all the other doors and it was the same situation. I was literally trapped inside my minivan. Someone tried opening it from the outside and that did not work as the doors had auto locked due to driving. The hood release mechanism worked fine, so I was able to pop the hood and a the mechanic jump started my battery and I was then able to unlock and open my car door. This is a serious safety concern as it suggests that an electric system shutdown due to fire, immersion in water, or other emergency situation would render any occupants stuck inside the vehicle. The mechanic evaluated the situation and said my alternator was broken and needed to be replaced. He did that successfully and I was back on the road in about 2 hours. It’s been running fine since then. I think this is a serious issue that Honda needs to address.

A few weeks ago a cable for the sliding door on the passenger side snapped. We were able to use it manually until this weekend when the whole door fell right off when sliding it closed.

Cable on passenger side sliding door snapped and door shut without latching on the arm of the person getting in.

The contact owns a 2012 Honda Odyssey. The contact stated while driving at various speeds, the vehicle lost motive power inadvertently in the middle of the roadway. There was no warning light illuminated. The contact was unable to veer to the side of the roadway. The contact stated that he shifted into park (P) and was able to restart the vehicle. The contact stated that the failure had been occurring approximately twice per day while driving. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 100,000.

The contact owns a 2012 Honda Odyssey. The contact stated while driving 30 MPH, several unknown warning lights were illuminated on the instrument panel. The vehicle was taken to an independent mechanic, who diagnosed a failure with the alternator. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 132,000.

Prior to the problem, the radio cut off, various lights (battery, abs, etc) lit up and Check System warning light appeared. The car remained running for approximately 10 miles although stepping on the accelerator did not always result in increased speed. Touching the brake caused the RPM gauge & speedometer to immediately drop to zero and removing my foot from the brake immediately resulted in both gauges resuming correct reading. Eventually, the car ceased to function and I removed the key. Then I tried to exit the vehicle. None of the doors would open and I remained in the car until my wife arrived with a spare set of keys which opened the door. A mechanic later determined the alternator needed replacement. Had I not had a mobile phone to call someone, I might still be there. Had the weather been either extremely hot or cold the consequences could have been life threatening

Misfiring, I have had to change the spark plugs and coils multiple times. I have contact Honda in Green Bay wi and Appleton wi, they have told me the recall has expired. We just bought this car this year from a none Honda dealership used. Had this problems days after getting it.

The contact owns a 2012 Honda Odyssey. The contact stated that on several occasions while driving at various speeds, the vehicle was jerking. The check emissions and check VSA (Vehicle Stability Assist) warning lights illuminated intermittently. The vehicle was taken to a local dealer however, the failure could not be duplicated. The contact stated that the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed that the piston rings needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 85,000.
