Filed Aug 31, 2025 · Engine · IN

For several years now, we have misfire issue or code P0304. We continue to change spark plugs cylinders. Both usually last a year or so then they need replaced again. I research the problem, no recall or the like. I did see his report on-line, wondering if it applies to us, Warranty Extension: MIL Comes On with DTCs P0301 thru P0304. Any help would be greatly appreciated.

Advisor, Thank you for regarding my request for warranty coverage for the critical misfire and overheating defect with my 2012 Odyssey Honda Engine 3.5L Engine.

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.
