Component Involved: Engine Lubrication / Cylinder Head / Variable Valve Timing (VVT) Spool Valve (Solenoid Assembly) and Electrical Charging System (Alternator). Vehicle Affected Example: Honda vehicles equipped with the 3.5L V6 (J35 Engine Series) with Variable Cylinder Management (VCM), including the Honda Pilot. Description of the Safety Defect & Failure Mechanism: The rear (bank 1) variable valve timing spool valve assembly is mounted directly above the vehicle's alternator. Due to thermal cycling and material degradation, the molded rubber gasket on the upper portion of this spool valve assembly experiences premature compression set and fails, resulting in a pressurized engine oil leak. Because of the physical packaging and architecture of the J35 engine, the oil dripping from this failed gasket falls directly into the open housing of the alternator located immediately below it. The engine oil contaminates the alternator's internal brushes, slip rings, and diodes, leading to a cat...

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.

Odometer Fraud. The contact owns a 2014 Honda Pilot. The contact discovered a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the mileage was 176,362. The vehicle became disabled two weeks after purchase, and was taken to an independent mechanic, where it was discovered that the mileage was 176,629. The mileage was verified by a Carfax Report.

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...
