2015 Honda Odyssey

On March 27th, I was driving my car. My children were with me and we were on the way home from swim practice. With no warning, my engine went crazy. We were sitting at a stop light and the idel became very rough shaking the entire car. The engine was slow to respond to the accelerator and ultimately I decided that it was not safe to drive. I had my van towed to my mechanic who ran diagnostics and confirmed that the spark plugs were misfiring because of oil build up related to a faulty piston ring valve. He explained that it was a common problem with Odysseys. He gave us the options of doing the major repair of the rings that would cost about $5000 or we could replace the failing spark plugs and get 6-8 months out of the car before the same issue would reoccur. Not having a spare $5k on hand we opted for the temporary fix. I recently received a warranty extension from Honda about this exact issue but Honda is refusing to repair my car. They have told me that unless the engine light is on and the appropriate codes are indicated, I can not have the repair covered by the warranty. I took in documents from my mechanic with pictures of the codes, but they will not honor this. They also said that even if they did an inspection that confirmed the piston ring failure, Honda USA would not pay them back for the repairs because the service light and appropriate service codes are not showing. I believe the terms of this warranty extension are in bad faith and put me and my family at risk. Either I spend my own money to repair the car, or I wait until the engine fails and me and my family are stranded on the side of the road. Despite numerous conversations with the service member and customer service, Honda refuses to put in writing their refusal to repair my car under the warranty.

My vehicle has a know issue with Honda Corporate with the variable cylinder management that has lead to 7 miss fires in 4 years. The frequent and excessive miss fires are caused by carbon and oil leaking through the piston rings. Honda has attempted to repair the piston rings but that repair was a fail. I’ve experienced a miss fire after the repair and now require another change to my spark plugs recommended by Honda. I filed a reimbursement case with Honda and was notified they will not resolve the issue or reimburse me for the excessive miss fires, spark plug and coils replaced due to their faulty know engine defect. They announced in July 2025 that they were extending the warranty to cover repairs related to engine misfires (DTCs P0301 through P0304) and will last for 10 years from the original purchase date or 150,000 miles. However they have denied my reimbursement after sending proof of miss fire work and payment.

The contact owns a 2015 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 17V725000 (SEATS); however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Back hatchback glass spontaneously shattered. Nobody was in the vehicle and it was in the garage. So- nobody was hurt; however, this may not have been the case had we been riding down the highway. From my research this is not the first time this has happened with this model vehicle. I plan to contact Honda today, if that is possible. I have pictures that show it could not have been hit by an object. It obviously was under pressure and caved from the sides.

The engine has experienced a cylinder 1 misfire condition twice in the last month. In each instance, the spark plug has been fouled with oil and caused the ignition coil pack to malfunction. When the failure occurred, the vehicle was in operation at roadway speeds and placed the vehicle into limp mode with a flashing check engine light and deactivating the forward collision monitor and lane departure warning. In each instance, the vehicle has been towed to an independent mechanic shop where the P0301 codes have been found. I have contacted American Honda Motors and was advised that there are no recalls at this point. Looking online, the 3.5L engine appears to have several issues regarding the VCM system that leads to ring failure and oil leaking into the cylinders. There was a class action suit, Soto et al. v. American Honda, that led to Honda extending engine warranties to 8 years, unlimited mileage, but does not correct the issue with the VCM causing damage. Thankfully for me each time the misfire condition has occurred, I have been close to home so that I have not been left stranded.

The contact owns a 2015 Honda Odyssey. The contact stated while driving at various speeds, several unknown warning lights flashed on the instrument panel. The contact stated that the vehicle jerked and lunged forward while depressing the accelerator pedal, as the vehicle would shut off. The vehicle was taken to a dealer where it was discovered that oil had leaked onto the alternator. The contact was provided an estimate for the repair. The manufacturer was notified of the failure and the contact was informed that the vehicle was not covered under warranty or recall. The vehicle was not repaired. The failure mileage was 135,000.

My two side doors do not close at times I have entered place of work and when I go to vehicle at lunch my side door is open. This has happened several times with coworkers closing my van sliding door I have stood there engaged sliding door and it just slides back through open. This is a safety as someone can climb into my vehicle while I’m away or my children can be hurt while closing doors. My doors red light on dashboard remains on for doors. My children have been in vehicle I close sliding door and the doors reopens my children constant statement doors opened again I get off slide them close and they reopen several times
