2013 Honda Odyssey

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 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 NHTSA 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 NHTSA 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)

​July 2022 - 6 spark plugs, 3 rear ignition coils, gasket set ​new/fixed (lots of various smaller fixes between these times) August 2023 - Check Emissions Light came on - replaced and switched the VV timing oil press switch and that quick fix had the light go away (lots of various smaller fixes between these times​, including the alternator - battery already replaced) November 2024 - Check Emissions Light came on - cylinder 2 is dead and 1 & 3 are misfiring. 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. Mechanic found the problem to be with the pistons, rings, oil and the vehicle's continues system to reduce miles per gallon of gas system. He replaced rings and pistons. The problems were identical to the service bulletin 1301 put out by Honda in 2015 yet this vin was not included. From Bulletin 1301 "Warranty Extension: MIL Comes On With DTCs P0301 Through P0304 (Supersedes 13-081, dated December 20, 2013, to revise the information marked by the black bars) REVISION SUMMARY Under DIAGNOSIS, VIN information was added to indicate which vehicles need software updates. BACKGROUND American Honda is announcing a powertrain warranty extension as a result of a settlement of a class action captioned, [XXX] v. American Honda Motor Co., Inc., Case No. [XXX] (N.D. Cal.). The piston rings on certain cylinders may rotate and align which can lead to spark plug fouling. This can set DTCs P0301 through P0304 and cause the MIL to come on. American Honda is extending the powertrain warranty to cover repairs related to engine misfire (that triggers DTCs P0301 through P0304) to 8 years with unlimited mileage from the original date of purchase and has settled a class action based on this remedial measure. This warranty extension does not apply to any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or insurer, or has a branded or similar title under any state’s law. CUSTOMER NOTIFICATION Owners of affected vehicles were sent a class action settlement notice regarding this warranty extension starting in October 2013.Before doing work on a vehicle, verify its eligibility by doing an iN VIN status inquiry. Refer customers seeking information about settlement benefits to www.enginemisfiresettlement.com, or instruct them to call 888-888-3082. CORRECTIVE ACTION Inspect the vehicle and, if necessary, clean the pistons, and replace the piston rings ... INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

The vehicle stalled continuously after a slight noise and speed dropped to 20-30 mph while driving on a freeway in Arizona at around 9 pm in the night. We had to pull to the side of the road and once I parked and turned off the engine, the vehicle would not turn on again. All lights -check engine, were on. Once it was towed to the independent service center, it was diagnosed as engine failure with two pistons burnt out and had to get that replaced. After researching , I see a recall for certain 2013 honda odyssey for engine pistons issue , (Link - [XXX] .) where it may not have been properly hardened during a heat treatment process. This engine issue caused a great safety risk in the middle of freeway, thankfully the traffic was light since it was late-night. We were 6 members in the car including kids and we were stranded by the side of the road until 11 pm until tow truck or other ride arrangements could be made. We spent approx $5000 for repairs , $1000 for towing and $500 for rentals. I can provide the receipts on request.

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.
