- Owners describe shuddering or shaking between 30 and 40 mph along with hard shifting, which some tie directly to recall campaign 20V668000.
- Some report the transmission suddenly dropping into neutral or a low gear at speed, with dashboard warning lights and loss of acceleration.
- A grinding noise from the rear end at startup that owners worked around by staying in front-wheel drive instead of all-wheel drive.
- Torque converter replacement was needed on at least one vehicle after a transmission fluid check, reported just after the mileage warranty had lapsed.
- Auto start/stop malfunctions where the engine fails to restart after the brake is released, leaving the vehicle stalled at a stop for several minutes.
