Typical electrical symptoms owners report
- A false rear door or window 'ajar' warning triggers chimes and flashing dome lights, often when turning, hitting a dip, or in hot weather.
- Headlights and brake lights illuminate on their own while the vehicle is parked, and shutting them off does not always stop them from coming back on.
- Batteries die unexpectedly, with dealers in some cases telling owners the vehicle needed to be driven daily to keep the battery charged.
- The radio display occasionally shows garbled or illegible information that clears only after the vehicle is turned off and restarted.
- Vehicles fail to start after only a few days of ownership, traced in one case to a defective battery.
