I own a 2014 Honda Pilot that experienced an engine misfire related to piston ring deterioration. An authorized Honda dealership diagnosed and documented qualifying engine misfire codes (P030X). After the misfire occurred, we stopped driving the vehicle due to safety concerns, including risk of loss of power or stalling. While the vehicle was not being driven, the battery failed and cleared diagnostic memory. Honda has acknowledged the prior diagnosis but refuses to perform the repair unless the vehicle is driven until the misfire occurs again and diagnostic codes are active at the time of service. Honda is requiring operation of a vehicle with a known intermittent engine defect to re-verify the condition. We believe this creates a safety risk by encouraging operation of a vehicle that may experience sudden misfire, loss of power, or stalling. We do not feel it is safe to drive the vehicle to intentionally reproduce the defect.

2014 Honda pilot touring--ENGINE-is running through oil faster than it should. The spark plugs/coil packs have all been replaced now. Starting with 1 an 3.I was driving down the road and it started stalling out while I was in traffic about 8 mo.ago . The vehicle didn't want to go anywhere an when it would get some power to go it was slow an the engine was shaking so hard the whole time even at idle. So I pulled over, turned car off an then on trying to get it home since I wasn't far at all. Finally the check engine light came on as I pulled in the drive. Put a code reader on it to find out that plugs 1.and 3 were misfiring., Fixed that problem and 2 months later it did the same thing. Checked codes again and seen now we needed to replace the rest of the spark plugs and all coil packs. Which made it run normal again. Dates are unknown at this point. Best guess it started about between 6 months an a year ago. We have had problems every since though. The check engine light came on again an the car was shaking and idling up an down an the code was- low transmission fluid. Transmission fluid doesn't leak unless something's wrong. There was none leaking and when we checked the level it was perfect We just turned the car off for awhile an when we started it back it acted fine. Seems like it could be something with the computer possibly?? There is so many more problems with this 14 Pilot. This thing shakes really bad during take off an slowing down. Drivetrain-- there is something in the front end making noise like it's gonna break any moment. Could be CV joint, hub assembly or numerous things. Also sometimes I can smell gas fumes or a burning smell and it doesn't show that it's overheating. ELECTRICAL- the doors used to unlock all over when put in park. Now only the driver door unlocks. Also the daytime running lights warning comes up on the dash. It stays on there. The taillights stopped working, wasn't a fuse or anything. Its the wiring. Paint-gone above windshield.

My 2014 Honda Pilot has intermittent engine misfires (DTCs P0301–P0304) caused by piston ring failure. The defect leads to rough running, sudden loss of power, and unsafe driving conditions. On October 24, 2024, Crown Motors Honda in Holland, MI confirmed piston ring failure on cylinders 1–3, with oil wash and fouled spark plugs. The vehicle had to be towed when my wife was driving due to loss of power. This vehicle is driven daily by my two high-school sons, often with my youngest as a passenger. The misfire and power loss create dangerous situations when merging, accelerating, or driving in traffic. Honda has refused to perform warranty repair unless the check engine light (MIL) is currently illuminated, even though their own Technical Service Bulletin 25-060 explains that stored codes and spark plug inspection are sufficient for diagnosis. Waiting for the CEL to reappear puts my children at risk of sudden failure. The defect has been confirmed by a Honda dealer, and is consistent with known issues covered by Honda warranty extensions and the Soto v. American Honda settlement. The problem is reproducible, poses an ongoing safety hazard, and remains unresolved.

2014 Honda pilot Misfire repeatedly happening. Changed spark plugs and coils 3 times continues to happen. I have had the above problem 3 times (check engine light flashing, VTM-4, traction lights all on. Check engine light started flashing, engine was revving weird. This is an ongoing issue that I am having to spend money on over and over. I have found on [XXX] that others have been dealing with the same situation. A recall needs to happen to fix this problem. I have been stuck on the highway with no fix out of the situation. Tired of having to take my car in for the same ongoing issue. Spending time and money that I don't have, P0303, P0305 codes that appear. They get fixed temporarily, then the same issue occurs. When driving long distances it becomes worse. Please HELP!

Last week I turned on my 2014 Pilot and saw the check engine and VTM-4 dash lights on. When I checked the cause I received error code P0303 - Piston #3 Misfire. Upon researching this error I discovered this issue was addressed by Honda for model years through 2013 because of a class action lawsuit. However models 2014-2015 have the same components and should be addressed/fixed by Honda. I’m lucky to have been in my driveway when I had the misfire, it could have cause an accident had I been on the road. Honda needs to issue a recall for 2014-2015 Pilots.

I have a 2014 Honda Pilot, and while driving on the road, the car started to violently shake, and the engine turned off. The inspection from dealer indicated code P0303- Misfire cylinder due to fouled #3 spark plug caused by worn piston rings. The spark plug was found to be melted. Honda quoted $4000 to fix the issue, and the concern is that the 2014 model could have also been included in the 2013 and earlier models. It appears that Honda has requested dealers to send in reports if this particular issue has been identified. Even though the dealership was aware of the diagnosis, they have not offered to cover the repairs for this known issue on previous models of Pilots. Instead, they are offering to buy back our vehicle. After further research, there has been a lawsuit "Honda Engine Misfire" with this same issue with Honda Pilot for year 2013 and prior. I want to know if my 2014 used 2013 parts, and therefore resulted to the manufacturer defect on my vehicle. The dealer has offered to buy back the car immediately and has not addressed our concerns with the vehicle having a faulty mfg part. Honda has not responded back to the issue and the issue has not been resolved. My concern is if this issue is not fixed that the engine may further malfunction causing more damage to the car.

On May 14 2023 I was driving my 2014 Honda Pilot when the Check Engine, VMT-4, and Stability Control dashboard lights all came on. I took my car to the local Honda dealer who said the #2 spark plug was fouled causing engine misfiring. I was also told I was low on oil. I have not seen any stains underneath the car but I was told the oil was leaking out past the piston rings and out the exhaust. I was also told by the dealer that 3 of the piston rings need replacing. And the cost is $5,000. The Honda service representative said there was no recall on this issue. But I found out later that the 2009 to 2013 Honda Pilots had a similar issue that was corrected by Honda at their cost. So why is there no recall for 2014 Honda Pilots ?? I am not rough on my car when I drive. So why should I have to pay $5,000 to fix a problem that Honda had in the 2009 to 2013 Pilots and apparently have not corrected for the 2014 Pilots ???? A quick internet search reveals other 2014 Pilot owners with similar if not the identical problem that I have.

Check engine light turned on one day and the vehicle started running rough. Immediately noticed an impact on being able to drive safely and could not operate the vehicle any further. I took the vehicle to a repair shop and they stated the piston rings need to be replaced and I am getting a cylinder #3 misfire. They also stated that my dealership should be able to fix this for free as it should be covered under a recall. I have already brought this vehicle in for a cylinder #3 misfire and cost me a fortune to fix. After researching I found that only models 2009-2013 were covered under this recall. Looking at the other nhsta complaints with people having the same exact issue it is clear that this issue has not been resolved and is yet stll happening in models 2014. Please extend this coverage to the year 2014.

Check engine and VSA light on. Vehicle jerks and shakes/ rough when slowing down. Diagnosis Misfire in cylinder two- foul plug ( that was just replaced), burning up oil rapidly. Piston rings are defective on a car with 75000 k miles. The repair is $5k after I just spent $2k on plugs, coils, replaced again, alternator. Undsafe and feels like car will crash. This was recall on 2013 and class action suit. Not on 2014 after they knew about issue!! Wreckless
