2015 Honda Odyssey Problems

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.

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.”

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.

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.

There is paint peeling off the back on my van. I have seen this issue on other Honda Odyssey’s (same year) driving on the road.

The driverside back automatic door cable broke down. I see other year's cars have a recall for the same thing but not my car.

The driver side middle row seat slide while driving back and forth and never latch into place every time you brake or accelerate

The contact owns a 2015 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 17V725000 (SEATS); however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

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 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.

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.

A spool valve leak occurred leaking oil onto the alternator which caused it to fail when driving. When it failed, electrical systems started to shut down. At first, the ABS system indicator lit up. Multiple systems started to fail soon thereafter. Upon pulling over on the freeway, the vehicle was unable to go in reverse. The root cause was a spool valve leak that is well known and consequently puts drivers at risk when driving at high speeds. When driving down the interstate, all the electrical systems started to shut down. The ABS system was the first indicator, along with multiple electrical systems soon thereafter. Once pulled over, the vehicle could not go in reverse as well. I now understand this to be a well known issue as published in Honda Technical Service Bulletin TSB [XXX] However, no information was sent to owners even though Honda has known about the issue since at least March 2020. This puts unnecessary safety risks for those driving with oil leaking onto the alternator resulting in electrical system shutdowns and issues driving. I believe a recall and safety notice should be issued. Yes, the component was inspected by Honda and replaced. The first indicator was the ABS system warning light along with many other systems shutting down. This occurred at a high-rate of speed on the freeway. Upon pulling over, the vehicle also could not go in reverse. I am frustrated Honda has known abut this issue for many years, but has not informed owners nor offered to correct the issue leading to safety issues and costly repairs.

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.

I am deeply concerned about the sudden breakdown of my vehicle due to the spool valve leaking onto the alternator and caused the loss of power and stalling of the vehicle while driving out of town and on an Interstate. This was an extremely scary time for me and my family being stranded on an expressway for over an hour and trying to figure out how to get my kids and family to safety. I have heard of others having the same issue with the same make and model vehicle and their repairs was covered by Honda. I don't understand why my issue would be any different and why my repairs are not currently covered by the Honda service bulletin. I would extremely hope honda take a deeper look at including my Vin in the service bulletin. I now understand this to be a well known issue as published in Honda Technical Service Bulletin TSB [XXX] However, no information was sent to owners even though Honda has known about the issue since at least March 2020. This puts unnecessary safety risks for those driving with oil leaking onto the alternator resulting in electrical system shutdowns and issues driving.

Back hatchback glass spontaneously shattered. Nobody was in the vehicle and it was in the garage. So- nobody was hurt; however, this may not have been the case had we been riding down the highway. From my research this is not the first time this has happened with this model vehicle. I plan to contact Honda today, if that is possible. I have pictures that show it could not have been hit by an object. It obviously was under pressure and caved from the sides.

The contact owns a 2015 Honda Odyssey. The contact stated that while driving at 55 MPH, she heard a loud explosion. The contact pulled over and noticed that the sunroof glass had exploded. There was no impact on the sunroof that could have caused it to shatter. The dealer was made aware of the failure, but the vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 102,000.

Fuel pump failure that was not a part of the 2.5 million car recall. Honda would not help.

I have replaced the vehicle pump 4 times in the last 6 months I’m driving vehicle stutters when going uphill then it just stops mid drive and when we have it checked the pump connector are charred. We replace fuel pump and wires and.within 6 weeks to 2 months I have to replace fuel pump again. It’s a safety issue as my vehicle can get into an accident or it can explode due to it burning the wires and connectors to fuel pump. I’m tired of replacing this item

had purchased my 2015 Honda Odyssey in the year of 2015. When I first went in for a first service my car have a light saying Check engine, check VSA, check LDW, check FDW and once a while my shake when we are on the road. We told the service people at the dealership to have a look at it but they said nothing wrong with it.

12/21/23: Wheelchair ramp and kneel function failed with no warning. This engaged safety feature that disables gear shift and keeps car in park. Unable to move car or deploy ramp using back-up override. Called Mobility Works (authorized VMI dealer). Troubleshooting failed to deploy ramp or kneel function. Told only option was to pop off tab next to gear shift and insert screwdriver to override “park” lock. Fortunately, quadriplegic spouse was not in the vehicle or he would have been trapped. 12/26/23 to 1/3/24: Vehicle inspected at Mobility Works, technician diagnosed controller board failure and recommended replacement. Told VMI lost supplier for controller board leaving no way to properly restore conversion equipment. On 1/3/24 spoke to VMI technician who confirmed controller board is unavailable. He stated VMI engineering department is trying to develop a workaround for a new controller board. VMI technician also reported two calls a day for this problem, and that it affects their Chrysler conversion equipment as well. 2/7/24: Telephoned VMI technical support. Told workaround for controller board will not be available for months. Told that if quadriplegic becomes trapped in car to call fire department. Told this is an acceptable solution in the mobility industry if back-up fails. Very cavalier, comparing to Ford no longer making fuel pump or fuel hose for his old truck. 4/18/24; 4/25/24: Emailed VMI requesting status of controller board replacement. No response. Conclusion: The controller board failed without warning, causing all conversion equipment to fail, including back-up override, and potentially trapping power wheelchair dependent individuals in their vehicles. VMI has failed to provide parts for repair of its conversion equipment. VMI authorized dealer estimates $1,000 to bypass controller board. This will cause certain accessibility functions to no longer work. The vehicle has been unusable for quadriplegic spouse since December 2023.

Passenger rear shock absorber separated at the top of the outer tube. Complete loss of damping and most of the shock oil. The shock absorber was in two pieces. Photos attached.

All cars slow down on the on the highway at construction area due to some debris flow. I slow down immediately. after that my seatbelt belt not retracting (stop working) and Air Bag sign was displayed. I took the car to the dealer and also contact HONDA (Corporate) by Live chat. Honda Corporate mentioned the following warranty is part of the Seat Belt, SRS system, and Airbag. As per the Honda warranty, all repairs must be complete without any charges. But I got the attached invoice(Cost of repair) to Fix the issue with the SRS system, Seat Belt, and Air Bag issue. According to the Honda warranty App parts and Labour must include I opened a claim with Honda (Case [XXX]) but so far I didn't hear from them. As per my understanding Safety issue related to my car must be fixed without any Charge. Also, Dealer must communicate with HONDA. So far I open a claim with insurance but not required because Honda must take care of or look at the Seat belt/Air Bag/SRS system. As per my understanding Issue with SRS system and AirBag are related with seat belt (Part of on function) See attached diagnosis Report from Honda Dealer. continues for 15 years or 150,000 miles, whichever comes first. Warranty Coverage Honda will, at its option, repair or replace any Honda seat belt component that fails to function properly during normal use. This includes all parts and labor charges.

7 year old in 2nd row passanger side seatbelt would not release and would only get tighter and tighter. Seatbelt got tighter and tighter around his belly causing pain and crushing his stomach. I had to cut the seatbelt to get him out. Tried pressing every button and opening and closing car door, locking and unlocking and restarting car, but nothing worked. The more we tried to pull on the seatbelt, the tighter it got. The seatbelt would not release or give any slack to get him out. I am taking car into the dealership for a dianostic this coming Friday.

THE ODOMETER DIAL IS VERY DIFFICULT TO SEE IN BRIGHT CONDITIONS. THIS YEAR THEY WENT TO WHITE LETTERS ON GRAY BACKGROUND. AT 70 MILES AN HOUR, STARING AT THE ODOMETER TO CHECK ONE'S SPEED IS SIMILAR TO READING TEXT ON A PHONE. I HAD CONTACTED HONDA A NUMBER OF TIMES TO ASK WHY WE CANNOT ADJUST THE LIGHTING SO THE NUMBERS WHEN LIT CAN BE VIEWED MORE EASILY. THERE IS A LIGHT DETECTOR BUILT IN THAT DOES NOT ALLOW THE DASH LIGHTS TO FUNCTION DURING DAYLIGHT. I HAVE HAD SEVERAL DANGEROUS EVENTS OCCUR DUE TO DRIFTING OF THE VEHICLE WHILE TAKING MY EYES OFF THE ROAD TO TRY AND READ THE DIAL. WHY CAN'T THEY FIX IT TO ALLOW USE OF DASH LIGHTING DURING DAYLIGHT? IT COULD BE AS SIMPLE AS ALLOWING THE DISABLING OF THE DAY/NIGHT DETECTOR.

HONDA IS USING SOY PRODUCT ON WIRING AND IT ATTRACTS SQUIREELS TO EAT MY WIRES. THE RODENTS ATE THE WIRES THREE TIMES SO FAR. WHILE DRIVING WITH CHILDREN IN CAR, MY BREAKS DID NOT WORK PROPERLY. I ALSO HAD NO WINDSHIELD WIPERS OR LIGHTS. IT WAS RAINING. IT WAS SO SCARY. I HAVE VIDEO OF THE SQUIRRELS UNDERNEATH THE HOOD

TL* THE CONTACT OWNS A 2015 HONDA ODYSSEY EQUIPPED WITH CONTINENTAL TIRES, TIRE LINE: PROCONTACT, TIRE SIZE: 235/65/R17 N/A, DOT NUMBER: A3873VM. THE CONTACT STATED THAT WHILE DRIVING AT 70 MPH, THERE WAS AN ABNORMAL BOUNCING OF THE DRIVER'S SIDE FRONT TIRE. THE CONTACT NOTICED THE TREAD HAD SEPARATED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSIS OR REPAIRS. A CONTINENTAL TIRE DISTRIBUTOR WAS CONTACTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 55,000 BOTH ON THE TIRE AND VEHICLE.

ABOUT 1:30 PM, MAY 23, 2015, I WAS DRIVING MY NEW 2015 HONDA ODYSSEY EX ON EAST BOUND OF RT 529 (PLAINFILD AVE) TO RT 1 IN EDISON, NJ, THE LEFT REAR BACK MICHELIN TIRE BLEW OUT ABOUT 100 YARDS AWAY FROM THE INTERSECTION. THERE WAS NOTHING ON THE ROAD. NOTHING WAS FOUND ON THE TIRE. I CALLED INSURANCE COMPANY, TOWING COMPANY, AND FINALLY I FOUND THAT A NISSAN DEALER IN RT 1 WAS JUST 200 YARDS AWAY. I SLOWLY DROVE THE VEHICLE TO THE DEALER, REPLACED THE SPARE TIRE. ON WEDNESDAY, I REPLACED A NEW MICHELIN SAME TIRE IN SWEENEY'S GULF AT EAST BRUNSWICK, NJ. THURSDAY, I WENT TO AUTOSPORT HONDA DEALER AT BRIDGEWATER, NJ WHERE I PURCHASED THE VEHICLE LAST OCTOBER. BUT THE DEALER AT FIRST DENIED THE TIRE HAD DEFECT, THEN THEY TOLD ME THAT THEY DIDN'T HANDLE THE TIRE WARRANTY, I HAD TO GO MICHELIN DEALER. ON FRIDAY, MAY 26, I WENT TO A MICHELIN DEALER IN OLD BRIDGE, NJ. THE STAFF TOLD ME THAT I HAD TO CALL MICHELIN TO SEE WHAT I SHOULD DO. I CALLED AND EMAILED MICHELIN. FOLLOWED THE INSTRUCTION, I WENT TO STS ON RT 18 TO CHECK. TODD CHECKED THE TIRE AND THE RIM, TOLD ME THAT THE TIRE HIT SOMETHING, WHICH CUT THE TIRE, NOT THE DEFECT BECAUSE HE SAW A SESAME BIG MARK ON THE EDGE OF THE RIM, WHICH CAUSED THE BLOW OUT. BUT HE COULDN'T ANSWER MY QUESTIONS: WHY THE FRONT TIRE WAS FINE? WHY THE TIRE NEAR THE RIM WAS NO ANY DAMAGE, THE BLOWOUT WAS IN THE MIDDLE OF THE SIDE OF THE TIRE, 3 INCHES AWAY FROM THE MARK ON THE RIM? WHY THE SHAP OF THE BLOWOUT WAS A IRREGULAR CURVE CRACK, NO STRAIGHT CUTTING EDGE AS HE SAID THAT SOMETHING CUT THE TIRE? I DIDN'T FEEL I HIT ANYTHING. I DIDN'T SEE ANYTHING ON THE ROAD. I STAYED THERE FOR ABOUT 1 HOUR BEFORE I TOOK MY CAR TO NISSAN DEALER. 529 IS A BUSY ROAD, AT LEAST HUNDREDS CARS PASSED IN ONE HOUR, NO ONE BLEW OUT. IT OBVIOUS THAT EITHER NOTHING ON THE ROAD, OR SOME TINY THING WHICH SHOULD NOT CAUSE A TIRE BLOWOUT. SO IT IS A DEFECT WHICH CAUSED THE BLOWOUT.

See attached document for complaint.
