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...

The contact's sister owns a 2013 Honda Odyssey. The contact stated that while driving 65 MPH, the contact noticed an unattended trailer hitch on the road and the vehicle drove over the trailer hitch, which rolled under the vehicle and bumped into the exhaust of the vehicle. The contact stated that the driver's side and passenger's side curtain air bags and seats airbags deployed. There was no warning light illuminated. All the passengers of the vehicle, which include the contact, the contact's husband and niece sustained injuries. The contact's husband sustained a bruised and swollen left elbow due to burns from the front driver's side seat air bag.

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 NHTSA 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 my...

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 NHTSA investigate this matter as a safety-related engine defect and urge the manufacturer to offer proper re...

Dear NHTSA Representative, I am writing to formally express my concern regarding the failure of Honda to notify me of a safety recall related to my vehicle, as required by 49 U.S.C. § 30119. As a current owner of the vehicle in question, I was never informed of the recall despite actively driving the car with my children, unknowingly putting our safety at risk. According to the law, manufacturers are obligated to obtain up-to-date owner information from state DMVs and notify all registered owners of safety defects or noncompliance issues. This lack of notification not only violates the legal requirements but also leaves me deeply concerned about how such an oversight occurred. As a consumer, I expect manufacturers to prioritize safety and follow mandated processes to ensure proper communication. I kindly request that you: Investigate why I was not notified of the recall in accordance with federal law. Take appropriate action to ensure no other current owners face similar risks. Pr...
