- Backup camera and rear indicator lights stay on continuously even after the vehicle is parked and turned off, requiring a restart that doesn't fix it.
- Infotainment system periodically freezes or fails, cutting off climate, communication, navigation, and settings controls while driving.
- Vehicle stalled and shut off completely at low speed, requiring towing, with owners reporting additional unrelated mechanical repairs afterward.
- Fuel gauge fluctuates or drops to empty inaccurately after refueling with no warning light, tied to a separate fuel system campaign referenced by an owner.
