On 4/5/19, my wife's honda pilot ex experienced severe engine problems on the road in fairview tn resulting in an inability to accelerate, hesitation when the gas pedal was depressed, and a flashing 'check engine' light. These symptoms were identical to an issue she had with this vehicle in 2017 that necessitated a tow to darrell waltrip honda in franklin tn for repair, and similar to less severe episodes of hesitant acceleration both she and I have experienced with the vehicle since at least 2016. Grassland car care center in franklin tn diagnosed the spark plugs were oil fouled causing a misfire. Engine codes p0301, p0302, p0303, p0304, and p0300 resulted from the incident. We have since learned this is a known defect with this model of honda and that the vcm-2 class action lawsuit resulted in a warranty extension of eight years from purchase date. We have an open case with honda of america (case manager: zoe; case #09478660), but are being told that our vehicle is outside the extended eight year warranty by four months. We contend this vehicle was experiencing problems consistent with the warrantied issue well before the 4/5/19 failure, to include the same type of episode supposedly repaired by darrell waltrip honda on 5/1/17. The sudden inability to accelerate on a roadway is a considerable safety concern. We are questioning why this wasn't a safety recall item. We have additional documentation available if needed.

While driving at highway speed (55 MPH) and then slowing down for traffic, the variable timing control actuator apparently stuck. The engine warning light came on followed by white smoke from the tailpipes. There was an immediate lack of power trying to accelerate again. This continued until the car was at a service shop. The mechanic indicated the engine went from 6 cylinders to 3 cylinders (eco mode) but never recovered. The trouble code was: p3400 means that the powertrain control module (PCM) has detected an abnormality in the cylinder deactivation system for engine bank one. Bank 1 denotes the bank of the engine which contains the number one cylinder. This problems appears to be the same as previously reported by other consumers. Honda needs to investigate and recall the vtc actuators.

Wife was driving at highway speed when car began to violently shake as if engine was misfiring. Check engine light came on, then severely reduced power. She was barely able to exit and make it across the access road and into a turn lane with the accelerator to the floor. Car still shook violently as she placed it in park. Dealership cannot explain shaking. Car only has 4,700 miles and was purchased new from servicing dealer. They said oil was 1.5-2 quarts low so they topped it off. Tripped a code for a stuck solenoid in the camshaft timing system so they reprogrammed the PCM and gave the car back to us. This was an extremely dangerous situation as my wife did not have enough power to move the vehicle out of traffic. Had there been more traffic in her way or someone following closely, she would have been in an accident. Dealer was still puzzled as to the power loss and shaking and just shrugged their shoulders. They said to watch the oil level and if this happens again to bring it back. We hope this does not happen again as it was dangerous and stranded my wife on the side of an interstate for 3 hours waiting on a tow truck. Please let us know if this warrants investigation or you need any additional information.

New 2011 honda accord (starting when the car got to about 500 miles on odometer): doesn't decelerate smoothly (gives a bit of a rough "braking" & acceleration action (a bit of a rough ride) & about 100-200rpm increase) through 20mph, then, again through 15mph. Honda dealer says there's nothing wrong because otherwise, the check engine light would go on. This occurs constantly every day, usually after the car has warmed up for about 10 minutes & gone from "cold" to about 45mph speed limit driving. I wanted to make a record of it here for now in case others experience this.
