Honda sent me a recall notice for piston ring deterioration which causes engine misfiring on August 1, 2025. I had the same issue with my Honda Odyssey and had it repaired in July 8, 2024 so I submitted a claim form for reimbursement. Honda denied my reimbursement request stating my work order did not contain a fail code readout. However, my work order stated that the engine misfiring was due to cylinder #1 and oil was found. The work order also states that the piston rings were replaced to correct the issue. The cause and solution are exactly the same as Honda's recall. This engine misfiring causes my van to lose power as I was backing out of the driveway. Had this happened on the freeway it would have been disastrous. I felt Honda is being disingenuous in its recall effort in denying me of the exact problem as specified in the recall.

This vehicle began using oil and the mechanic I took it to told me that the piston rings were compromised. This was allowing mixing of oil and gas, overuse of oil, intermittent white plumes of exhaust and causing misfires, fouling of plugs and set off codes pertaining to the piston rings as well as the catalytic converter. He changed the spark plug and told me my options were a rebuilt engine or to replace it. It would continue and it would get worse. Honda issued a warranty extension realted to misfire dondition related to piston ring deterioration (DTCs P0301 - P0304.) The dealer I took it too states that since the above mentioned codes are not present, they cannot perform the warranty work. The dealer did ask and corroborate that changing the spark plugs will "buy time" and is a cheap fix that does not correct the issue but may extend the life of the engine. The mechanic agrees that the issue being warranted is the issue i was experiencing but does not have a copy of the codes to prove it. I am frustrated that this warranty clearly applies to my vehicle, but because I hired a mechanic previously who has prevented the codes from being present, I am out an engine. Please help

I’m reporting a repeat engine misfire on my 2013 Honda Odyssey (P0303 – cylinder 3). Honda repaired this issue in 2018 under Service Bulletin 13-081, which followed the Soto v. Honda settlement. Now in 2025, the exact same failure has returned—same code, same cylinder, same symptoms. Honda issued a new bulletin, 25-061 (June 17, 2025), covering 2013–2016 Odysseys with misfire codes P0301–P0304. It extends powertrain warranty coverage to 10 years or 150,000 miles, and includes a grace period through Jan 31, 2026 for any affected vehicle, regardless of mileage or age. My vehicle meets all criteria, yet Honda refuses full coverage, saying my VIN isn’t flagged and they can’t override that due to the federal safety agency restrictions. This seems inconsistent. The bulletin clearly applies to my make, model, year, and exact engine fault. The misfire affects drivability and long-term engine health. I’ve been a loyal Honda customer, servicing the vehicle at authorized dealerships and covering related repairs myself. In addition to the engine problem, I’ve experienced electrical instability due to a faulty battery cable, which required replacement. I’ve also had to address a damaged transmission drain bolt—caused during prior dealer maintenance—which complicated fluid service and added cost. I’m asking the federal safety agency to review whether more VINs should be included under this bulletin, and whether Honda is limiting support too narrowly despite formally acknowledging the defect. I’m providing invoices, diagnostics, estimates and service records to support this including the video inspection.

My 2013 Honda Odyssey is experiencing a serious engine malfunction related to excessive oil consumption and spark plug fouling. On [XXX], the Check Engine Light came on and the vehicle began shaking. A diagnostic inspection at a Honda dealership revealed DTC P0301 (Cylinder 1 Misfire). Three spark plugs in Bank 1 were heavily fouled with oil. The technician recommended piston ring replacement, noting that oil had leaked into the combustion chamber. This issue is consistent with well-known engine problems associated with Honda's VCM (Variable Cylinder Management) system. TSBs such as A13-081 and 11-033 have addressed similar issues in the past, but my vehicle is no longer covered under the extended warranty. I am a low-income international student currently living in the U.S. with my family. This defect creates financial hardship and safety concern. I respectfully request that the federal safety agency investigate this matter as a safety-related engine defect and urge the manufacturer to offer proper recall support. - Mileage at most recent diagnosis: 116,520 miles - Current mileage: 117,300 miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Need new cylinders and spark plugs, etc. Honda should do something about this as this is a common issue with these years of Odyssey vans.

Engine backfired and failed at 125000 going 60 mph on major highway.

Engine misfire causing vehicle loss of speed. This vehicle problem was recalled per Soto et al. v. American Honda Motor Co., Inc., Case No. 3:12-cv-1377-SI (N.D. Cal.). However, it was limited to 8 years after purchase. I feel this recall should be covered longer as my vehicle has only 125K miles and requires engine rebuild costing approximately $3000.
