2014 Honda Pilot engine problems

“The contact owns a 2014 Honda Pilot. The contact stated that while driving approximately 70 MPH, there was a loud pop coming from the engine department. The contact became aware of a severe drop in the oil level while driving the vehicle. The vehicle was taken to a dealer to be diagnosed, and the contact was informed that there was a misfire in cylinder #4, and that the engine needed to be rebuilt. The engine was rebuilt. The contact stated that while driving 30 MPH, the engine sputtered with the check engine and several other warning lights illuminated. The failures persisted. The vehicle was towed to another dealer, Friendly Honda of Fayetteville (534 E Genesee St, Fayetteville, NY 13066); and was diagnosed with piston rings failure. The vehicle was not repaired. The contact stated that the spark plugs, and alternator were also replaced. The manufacturer was made aware of the failure. The manufacturer opened a case regarding the failures. The approximate failure mileage was 142,000.”

“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…”

“10/27/2023 replaced all spark plugs 12/16/2/24 Engine light and VTM-light and traction control light on, misfire in 1st cylinder, replaced spark plugs and ignition coil 1/9/25 Engine light and VTM-light and traction control light on, misfire in 3rd cylinder. These issues are consistent with many complaints on this year, make and model of Honda Pilot”

“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.”
