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 is able to provide me a date of when it will be reimbursed.

I bought this car from a dealer in November of 2025 just over 95k miles. Two weeks after I bought it a PO303 code for a cylinder 3 misfire appeared. I changed the spark plug and the code went away. Then on Friday, April 10th, the code came back. I replaced the spark plug for a 2nd time. The code disappeared again. 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 car to an auto mechanic in my area. After their diagnosis I am looking at either repairing the current engine at a cost of 4500 dollars or replacing the engine at a cost of 7-8k. I believe my engine issue is the very same issue that 2011-2013 3.5l v6 Honda engines suffer from that resulted in a lawsuit and settlement.

The contact owns a 2015 Honda Odyssey. The contact stated that while driving at various speeds, the vehicle would hesitate to accelerate as intended while the accelerator pedal was depressed. The check engine warning light illuminated. The vehicle was towed to a local dealer, where it was diagnosed with a piston ring failure and related the failure to Honda Service Bulletin:25-061. The vehicle was not repaired due to cost. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

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 Cylinder Management (VCM) system causing excessive oil consumption and spark plug fouling — an issue documented across 2013–2017 Odyssey vehicles and addressed under Honda Service Bulletin 25-061. I am requesting this complaint be on record and urge NHTSA to investigate this as a safety-related defect.”

I am submitting this urgent complaint regarding my 2015 Honda Odyssey, equipped with the 3.5L V6 engine referenced in (TSB) 20-023 which acknowledges that the front rocker arm oil control valve (spool valve) gasket may fail and leak engine oil directly onto the alternator located beneath it. This condition can cause alternator contamination, charging system failure, electrical malfunction, and potential fire risk due to oil exposure to electrical components. Despite knowledge of this issue, Honda did not notify vehicle owners and did not initiate a recall. Before the first breakdown occurred, I experienced a frightening and dangerous incident while in traffic. Without any human interference and without my pressing the accelerator, the vehicle suddenly accelerated and moved forward on its own, nearly striking the vehicle in front of me. I had to react immediately to prevent a collision. This unexpected surge was extremely disturbing and appeared to involve an electrical malfunction. Shortly thereafter, the vehicle broke down. After the first breakdown, I replaced the battery. Within approximately one hour of driving again, the vehicle failed again due to alternator failure. I was stranded at night, in darkness, alone, and exposed to active traffic. This created an immediate and foreseeable risk of collision, serious bodily injury, or death. Another car in that area around that time broke down on the highway I was expected to use and was hit by a semi on 95 and the driver of the stopped car was killed. That could have easily been me. A defect that can cause sudden electrical malfunction, unintended vehicle movement, loss of charging capability, vehicle disablement in traffic, and potential fire hazard constitutes a safety-related defect under federal motor vehicle safety standards. I respectfully request that you Initiate a formal investigation Evaluate whether a recall is warranted. Require reimbursement for repair costs Thank you very much.

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 minimum necessary repair to restore drivability, as the warranty extension had not yet been issued and the vehicle could not be operated safely without immediate service. Honda has acknowledged that this repair was temporary and consistent with the covered condition. Honda has denied reimbursement for this repair because the piston ring or short block replacement identified in the campaign was not completed. Honda has also stated that it will not perform the covered repair unless the misfire code is currently active or stored and the check engine light is illuminated. Honda representatives have acknowledged that this condition commonly recurs after a temporary spark plug repair, but have advised that no repair can be performed unless the issue resumes. This creates a situation in which the vehicle has a known covered defect, but access to repair is delayed until failure reoccurs, potentially outside the warranty extension mileage or time limits. I am submitting this complaint due to concerns that these requirements may prevent timely access to emissions-related repairs for a known defect and may discourage reasonable interim repairs necessary to maintain safe vehicle operation. Honda’s requirement that I continue operating the vehicle until the misfire reoccurs raises safety concerns. The prior failure resulted in loss of drivability, and I am uncomfortable transporting my family while knowingly operating a vehicle with a documented defect that Honda has acknowledged is likely to recur.

On December 31 at approximately 300 p.m., our 2015 Honda Odyssey experienced a sudden and complete loss of motive power while traveling eastbound on the Sam Houston Parkway South just after crossing the Buffalo Bayou Toll Bridge at highway speed. While driving normally, the Check ABS warning light illuminated. Immediately afterward, multiple dashboard warning lights began flashing and the engine abruptly shut down with no warning. The vehicle lost all ability to accelerate and became disabled in active traffic lanes. Steering and braking were severely affected due to the sudden loss of power. Hazard lights were activated while the driver attempted to move the vehicle from the middle lane to the shoulder. We narrowly avoided a collision and were able to stop near the Pine Avenue on-ramp. Once stopped, the vehicle completely shut off and would not restart. All vehicle systems appeared inoperative except for the hazard lights, indicating a possible electrical system failure. Emergency services were required due to the dangerous location. The vehicle was occupied by five people, including three children. The sudden loss of motive power at highway speed created an extreme safety hazard and could have resulted in serious injury or fatality.

The car sporadically does not shift from 1st 2 second and then abruptly shuts cause a loud jerk of engine and car. It is startling and scary when it happens. I’m afraid the car will break down while in the road. Every time we take the car to dealership they “cannot replicate” issue therefore there is nothing to fix on an issue that is all over the internet with Honda vans and suvs.

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.

What happened? When I took my 2015 Honda Odyssey (VIN: [XXX] ) to a Honda dealer for service, I was told Honda’s internal database incorrectly shows the vehicle as having a salvage/junk title. Minnesota DMV records confirm my title is clean. Component/system affected: This error prevented the dealer from performing warranty-covered inspections and potential repairs on safety systems including brakes, electronic stability control, and adaptive cruise control. These systems are still in use and available for inspection upon request. Safety risk: By denying service due to an incorrect salvage status, the vehicle could continue operating with undetected or unrepaired safety defects, putting myself, my passengers, and other drivers at risk. Confirmation: The problem was confirmed by the Honda dealer’s service department, which refused service solely due to Honda’s salvage designation. Inspection history: The vehicle has been inspected by the dealer but no repairs were performed because of the incorrect salvage status. The Minnesota DMV verified that my title is clean and unbranded. Warning signs/messages: There were no warning lamps prior to the incident; the issue arose only when the VIN was entered into Honda’s system for service.

I am reporting an engine defect covered under Honda’s recent warranty extension for 2013–2017 Odyssey / 2013–2015 Pilot vehicles when the MIL comes on with DTCs P0301–P0304. On November 1, 2022, I was stranded on the road when the check-engine light came on. At Honda Muller of Gurnee, the dealer diagnosed misfires consistent with P0301–P0304, explaining the underlying cause as piston ring function deterioration with sludge causing oil to foul the spark plugs. I was told my original warranty had expired only about six weeks earlier (on August 29, 2022). Coverage was denied and I was quoted over $6,000. Because I couldn’t afford the repair, the dealer recommended replacing the spark plugs as a temporary measure only, stating this would not fix the underlying defect. I proceeded with that temporary measure. On November 11, 2022, American Honda formally acknowledged my concern in writing, confirming that Case #13455791 had been opened and escalated to a case manager in direct response to my diagnosis from November 1, 2022. Despite this acknowledgment, my repair request was denied. In 2025 I received Honda’s warranty extension letter acknowledging coverage for this exact defect (including coverage through January 31, 2026). I returned to the dealer seeking repair based on my documented diagnosis, but repair was refused again because the codes were not present that day (the condition is intermittent). This defect affects drivability and safety (loss of power/hesitation and reduced ability to merge or cross traffic). I am asking NHTSA to record this complaint and consider action so that owners with documented prior diagnoses — especially those recognized by Honda corporate — are not refused repairs simply because an intermittent defect isn’t active at the exact moment of inspection. I am reporting an engine defect covered under Honda’s recent warranty extension for 2013–2017 Odyssey / 2013–2015 Pilot vehicles when the MIL comes on with DTCs P0301–P0304.

On March 27th, I was driving my car. My children were with me and we were on the way home from swim practice. With no warning, my engine went crazy. We were sitting at a stop light and the idel became very rough shaking the entire car. The engine was slow to respond to the accelerator and ultimately I decided that it was not safe to drive. I had my van towed to my mechanic who ran diagnostics and confirmed that the spark plugs were misfiring because of oil build up related to a faulty piston ring valve. He explained that it was a common problem with Odysseys. He gave us the options of doing the major repair of the rings that would cost about $5000 or we could replace the failing spark plugs and get 6-8 months out of the car before the same issue would reoccur. Not having a spare $5k on hand we opted for the temporary fix. I recently received a warranty extension from Honda about this exact issue but Honda is refusing to repair my car. They have told me that unless the engine light is on and the appropriate codes are indicated, I can not have the repair covered by the warranty. I took in documents from my mechanic with pictures of the codes, but they will not honor this. They also said that even if they did an inspection that confirmed the piston ring failure, Honda USA would not pay them back for the repairs because the service light and appropriate service codes are not showing. I believe the terms of this warranty extension are in bad faith and put me and my family at risk. Either I spend my own money to repair the car, or I wait until the engine fails and me and my family are stranded on the side of the road. Despite numerous conversations with the service member and customer service, Honda refuses to put in writing their refusal to repair my car under the warranty.
