2012 Honda Odyssey: check engine light

Filed May 16, 2026 · Transmission · OH

piston rings wore out prematurely on our 2012 honda odyssey. this was caused by the vcm system. its a known issue on hondas. it only had 88,600 miles at the time. we were driving our 2012 honda odyssey in december 2023. the check engine light began to flash. it starting running rough. we had it towed to a honda dealer for inspection. they pulled codes p303 and p304. they said the rings were worn and spark plugs fouled. they said this is a common issue because of the vcm. they peformed a rering job and with all parts and labor the cost came to $4000. we are very disgusted that this issue was already known by honda and they failed to place the vehicle on recall or wave the repair cost. they had a previous recall for this issue, but they say it was for a limited time frame. my mother only drives less than 10k miles a year, so the issue wouldnt have happened before 2016, as the miles on her van were still very low. we are issueing a complaint against honda for this issue. we are asking for reimbursement for the repair for the piston ring job which was $4000 while we had the vehicle in for this repair, we were also informed of other issues with the van, and we went ahead with those repairs as well, which brought our repair bill total to over $6419, which is also shown on the same receipt.

The check engine light started to blink and the vsa came on as well. This happened after I pulled into our driveway thank goodness because the engine started to shake the car. We took the van in our local dealership and it had a p0302 code. Engine misfire. This was caused by oil getting into the spark plug. Piston and ring job was recommended. The 2012 honda had a tsb 11-033 for this issue. We are being denied our claim. I am including a picture of our spark plug that shows where there was a lot of oil when it was fired upon along with talks I have had with honda.

My wife was driving out 2012 honda odyssey on a highway and the check engine light started flashing. She pulled over, turned off the car and restarted it. After a short period, the light flashed again. She had a aaa tow the vehicle back to our mechanic, who indicated that some of the spark plugs had fouled, and he notified us of the "excessive oil consumption" issue related to these vehicles, a know issue to honda. The mechanic indicated that the excess oil consumption will be an ongoing problem. The oil gauge on the vehicle indicated falsely indicated that the oil level was fine, so there is no warning that the engines are about to fail. This is a dangerous condition, and puts families at risk for as long as they own vehicles with this problem.

There was a check engine light and upon inspection, honda notified me that the piston ring replacement was necessary and that honda extended the warranty to 100k miles. The problem was the timing belt and few other parts needed to be replaced because they would get damaged during this warranty repair. Honda refused to pay for the timing belt replacement and made me pay almost $800.00 in parts and labor. 2. My car stared to vibrate every time I braked from about 15k miles. I took it in and instead of making the proper repairs the service center had the front rotors re-surfaced 3 times. The problem kept on coming back because the front rotors are undersized for the vehicle. I had to buy my own front rotors from a generic maker along with pads to correct the problem. It cost me $350 for parts and $200 at honda service center to repair it properly. 3. There's a popping sound when I make turns. I've addressed it and no one will fix it. I don't think its normal that clicking and popping sound comes while steering.
