2015 Honda Odyssey

My rear passenger sliding door is stuck open and won't close.

2015 Honda Odyssey Touring Elite, VIN [XXX]. Vehicle was involved in a frontal collision on XXX. The driver's frontal airbag did not deploy. During the impact, I was thrown forward and struck the steering wheel. Additionally, a side/sliding door opened during the collision. The door was closed before the collision. I am concerned about possible failures of the supplemental restraint system and door-latching system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2015 Honda Odyssey. While the contact's fiancé was driving 30 MPH with the contact seated in the passenger's seat, the passenger's side air bag deployed without impact. The contact sustained injuries to the right arm and neck. Medical attention was provided. The air bag warning light was not illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 221,092.

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 notice and realized that the issue I experienced may have been related to the condition covered by the warranty. I contacted my local Honda dealership in August 2025 and explained the prior misfire, repairs performed, and the warranty notice I had received. However, because the check engine light was not currently illuminated, I was told there was nothing that could be done unless the vehicle was actively displaying the issue. I also contacted Honda Corporate regarding this matter. I was advised that reimbursement for some of the repairs I had already completed might be possible, but that it would need to be reviewed. I chose not to submit those receipts at the time because I was concerned that doing so might impact my ability to use the extended warranty coverage if the problem returned. Unfortunately, the issue appears to be progressing. On June 2, 2026, the vehicle set a P3400 code, which is related to the Variable Cylinder Management (VCM) system. At that time, the oil level was low. After adding oil and completing several driving cycles, the check engine light turned off. However, the vehicle continues to consume oil at an alarming rate. I have had to add additional oil again in July. The problem is progressing - it is the issue that should be covered by warranty but holds refuses to do anything because the light isn’t currently on,

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 (Invoices XXX and XXX). I submitted complete reimbursement documentation on January 31, 2026. Honda has withheld my funds for 178 days (which is 122 days past their promised 8 week deadline) while corporate customer care agents falsely claim payment is “approved but pending final management sign- off.” I have called 11 times and corporate managers who are never available HAVE NEVER returned my calls like the representative with Honda I've spoken with each time assures. This deliberate delay subverts federal safety campaign integrity and artificially manages liability exposure. Request immediate enforcement action for an ongoing corporate warranty evasion pattern.

I drove very slowly over a speed bump by my local public high school and my airbags deployed. My hand was burnt from the airbag, my insurer gave me 14K + to repair the car, but that was not enough and so I took the money and bought a different car. furthermore because of this , my insurer increased significantly my monthly premium. My young children were in the car and were terrified. My insurer also only paid for a certain amount of days with the rental car, and I had to pay out-of-pocket for the other days.

Odometer Fraud. The contact purchased a 2015 Honda Odyssey. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 150,000. After reviewing a Carfax report, it was discovered that the mileage was 154,000.

The contact owns a 2015 Honda Odyssey. The contact's stated while her husband was driving 25-30 MPH,  occupied with her their two children, he was attempting to make a right turn and he got distracted due to a medical emergency with one of the daughter 's having a seizure in the right rear driver side of the vehicle  and then the vehicle collided with the curb causing the vehicle to crash into a mailbox, two trees and a light pole. The contact stated that no air bags deployed in the vehicle. The contact stated no injuries. No medical attention was required. The contact stated that a police report was filed. The vehicle was towed to contact residence and the next day will be towed to a collision center. The contact stated that the failure was not diagnosed by a dealer or independent mechanic. The manufacturer was notified of the failure and informed her there were no recalls on her vehicle. The approximate failure mileage was 178,581.

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.

The automatic sliding doors are malfunctioning and will not open. We bought this vehicle used from Fred Anderson Kia of Greenville.

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.

Odometer Fraud. The contact purchased a 2015 Honda Odyssey. It was discovered that there was a discrepancy in mileage. The vehicle was a private sale. At the time of purchase, the mileage was 96,000; however, upon registration, it was discovered that the actual mileage was 222,000. While registering the vehicle, the contact was informed that the registration and the Carfax report presented to them at the time of sale had been modified, and there was evidence of Odometer Fraud. The contact was referred to file reports with the local Law Enforcement and with the NHTSA Hotline. The contact was unable to file a report with Law Enforcement and was redirected to the NHTSA Hotline.
