What owners report

  • Vehicles fail to start on the first attempt, sometimes with an abnormal engine-compartment sound, then return to normal for a while before the problem recurs.
  • The transmission hesitates or loses power when pulling away from a stop or switching lanes, described as the torque converter not engaging RPM properly.
  • The airbag warning light illuminates and flashes at highway speed; dealers found a loose wire but the failure returned days later.
  • After the transmission parking-pawl recall software update, owners report fuel economy dropping from 21 MPG to 18 MPG and a warning light cycling on and off.
  • A tire sidewall failed at 70 MPH on the highway, causing sudden deflation and a low-tire warning shortly after.
  • The engine seems to momentarily cut out while descending a slope in first gear with a low fuel level, with the tachometer still showing the engine running.
