   I first experienced an engine misfire in February 2025. The vehicle had a P0301 misfire code, and at the time I was unaware of Honda’s extended warranty related to this issue. We had a trusted mechanic friend inspect the vehicle and replace the spark plugs and ignition coils. He noted that there was significant carbon buildup. After those repairs, the vehicle appeared to run normally, and we believed the issue had been resolved. Later, I received Honda’s extended warranty…

   American Honda Motor Co., Inc. issued an official Warranty Extension in July 2025 covering engine misfires from piston ring deterioration (DTCs P0301-P0304) on 2013-15 Pilot and 2013-17 Odyssey vehicles. My 2015 Honda Odyssey (VIN: [XXX]) experienced this exact defect, resulting in severe engine misfires and secondary alternator failure caused directly by engine fluid saturation leaking onto it from the primary defect. I paid $5,275.80 for repairs prior to campaign awareness…

   I had an engine failure on my odyssey that was causing a single piston to misfire - that i then had a honda dealer repair for around $3500. A couple months later i received a letter indicating this specific type of error was now under a recall for my vehicle so i submitted all the documentation for the recall reimbursement. That was in August of 2025 and I have still not received reimbursement - each time I contact Honda i am told this is just the normal process but nobody…

Then, on April 25th the code returned and I replaced the cylinder 3 spark plug for the 3rd time. After replacing the cylinder 3 plug for the 3rd time I took the…

   Our 2015 Honda Odyssey van has bad piston rings 1-3. The check engine light and all of the lights are on in the vehicle is not driving and idling poorly.This is the second time it has happened. The first time was under warranty at 112,000 miles, and now the van has 179,000 miles. There seems to be several recalls and known problems and warranty was extended last year, but we just missed it. The code is P0301. I took it to the Honda service and the spark plugs are fouled.

   In November 2024, the engine of my 2015 Honda Odyssey misfired and I had all spark plugs replaced. The vehicle had 102, 171 miles on it. The issue was resolved at that time. On April 1, 2026 the engine misfire returned, check engine light came on and the repair shop advised that again the engine is having the same issue. The vehicle now has 117,000 miles on it. This does not appear to be an isolated case as I have read several other similar complaints.

   Approximately 7 months ago, my 2015 Honda Odyssey experienced an engine misfire with code P0302 (cylinder 2). All spark plugs were replaced at that time and the issue appeared resolved. However, the misfire has now returned with the check engine light on, again indicating cylinder misfire. The vehicle only has 71,000 miles on it, which makes this recurring issue particularly concerning. Based on my research, this appears to be a known defect related to Honda’s Variable…

   Honda issued a warranty extension covering piston ring deterioration that causes engine misfires (DTCs P0301–P0304) due to oil fouling. I experienced this exact condition on 3/11/25 prior to issuance of the warranty extension, resulting in an engine misfire and loss of drivability. To restore basic operation of the vehicle, an independent repair facility replaced a fouled spark plug, documenting the misfire and oil fouling condition (including the P0301 code). I elected the…

    American Honda Motor Co, Inc. recently sent a warranty extension due to piston ring deterioration causing misfires. They have improperly denied my claim for reasons that were clearly arbitrary and to get out of reimbursing me for the repair. This is a safety concern because the car is unable to accelerate safely to merge onto an interstate and puts other drivers at risk.
