Typical transmission symptoms owners report

  • Vehicle unexpectedly loses power or stalls while driving, sometimes requiring towing after the engine cuts out with no warning.
  • Transmission fails to engage from a stop, with the engine revving while the gear does not respond, delaying acceleration when merging or turning.
  • Transmission or gear shifter shifts itself into park or neutral while the vehicle is still moving, in some cases causing a sudden stop in traffic.
  • Owners report internal transmission failure requiring full replacement, with some replacement units also developing hard shifts or fluid leaks.
  • A driveshaft fracture was reported after an abnormal popping noise from underneath the vehicle during a turn.
  • Vehicle enters a derated, low-power mode repeatedly during highway driving, with dealers unable to permanently resolve it despite software updates.
