2017 Toyota Tacoma engine problems

“Truck has 116k miles, started losing power and acceleration diminished. CEL and Trac Off light came on. Pulled over twice after experiencing same issue. Took to mechanic and diagnostic code P0301 (cylinder 1 misfire). Replaced 6 spark plugs to be safe, and replaced broken coil in cylinder 1. Drove less than a mile and CEL came back on. Brought to dealership this time and they found a leak in the head gasket and noticed warping in cylinder 1, along with code P0301 still present. They reported back to me stating it needed a machinist to resurface the the cylinder head, that the repair is mechanical. Even outside of warranty this fix should not be costing $13,000. The truck has been properly maintained for the past 9 years, all oil services and replacing any wear and tear items. Mechanical (warping) is manufacturing issues.”

“The contact owns a 2017 Toyota Tacoma. The contact stated that while driving, the engine revved lightly. Over time the vehicle began to lunge forward, and the revving had become more intense. The RPM increased and revved. While reversing, the vehicle lunged. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the failure was due to the map sensor and throttle body. The vehicle was repaired, but the failure recurred. The manufacturer was not notified. The failure mileage was approximately 75,000.”

“I was driving on the highway when my vehicle suddenly lost power. The engine light and traction control light came on, and I lost power, and the engine started sputtering. I had to pull off to the side and put on hazards. My Tacoma would only drive about 25 MPH after this happened. Based on a quick search, this is a very common problem in 3rd-generation Tacomas!”
