Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Infotainment MIB3: Software bugs and system crashes The MIB3 infotainment system shows software bugs such as screen crashes and camera failures. Software updates fix most of the problems. Symptoms: Black screen, reversing camera non-functional, error messages for airbag or start-stop from 30,000 km | Low | |
| Reversing camera remains black The reversing camera no longer shows an image, usually caused by a defective control unit or cable break at the connector. Software version 1896 partially resolves the issue. Symptoms: Black image when reverse gear is engaged, intermittent camera failure from 40,000 km | Low | |
| Front low-beam flagged at roadworthiness inspection Front lighting is rated as somewhat critical in TÜV reports. LED control units can fail, and headlight lenses show premature fogging. Symptoms: Low-beam flickers or fails on one side, moisture inside the headlight housing from 60,000 km | Medium |
