Typical engine symptoms owners report

  • Owners report sudden unintended acceleration to full throttle, sometimes reaching over 90 mph, with brakes, cruise control shutoff, and ignition off failing to stop the car.
  • Some drivers say the vehicle stalled or surged without warning at low speeds, in one case while parking and in another while driving around 25 mph, leading to collisions.
  • Several complaints describe engine fires, including one where smoke and oil appeared from under the hood with a low oil pressure warning, and others where a parked, powered-off car caught fire.
  • One owner reports a mechanic identifying a rocker arm control issue tied to oil loss and smoke at low speed.
  • A check engine light triggered by an EVAP canister vent valve solenoid issue led to a repair that GM later addressed through a customer letter.
