Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Electronic steering lock seizes The electronic steering column lock can seize and prevent the car from starting. BMW charged around 1,800 € for repair. One of the most expensive electrical problems of this generation. Symptoms: Car won't start, ignition binds or locks, steering wheel immovable, fault message on instrument cluster. from 100,000 km | High | |

Even minor repairs easily cost over 1,000 €. Symptoms: Various warning lights simultaneously, comfort access no longer works, windows and seats don't respond. from 80,000 km | High | |
| Boot water ingress — control units wet Blocked panoramic roof drains let water through the C-pillar into the boot. Up to 7 control units are located there. Symptoms: Simultaneous failure of gearbox, DSC, Dynamic Drive; damp carpet in boot. from 100,000 km | High | |
| Electronic cascade failure from low voltage A weak battery causes apparent multiple faults: Dynamic Drive, DSC, gearbox, and steering show simultaneous errors. Symptoms: Multiple warning lights simultaneously, gearbox in limp mode, 'Steering fault'. from 80,000 km | Low | |
| Comfort access failed The E65 comfort access fails frequently — from flat key batteries to faulty door handles and the CAS control unit. Diagnosis is complex and repairs accordingly expensive. Symptoms: Doors cannot be opened or closed via comfort access, key not recognised, immobiliser activates. from 100,000 km | Medium |
