What 64 owners told NHTSA about the 2012 BMW 535i

The headlights on the BMW 535 collect excessive amounts of condensation. If the condensation builds up, then the light does not function properly. The main safety concern is the malfunction of the turn signal. It will function in the rear of the vehicle but does not light up on the front in the affected headlight housing. Review of this problem on-line shows that this has occurred in many BMW vehicles and BMW also has issued a service bulletin for this problem (SI B63 05 16). As widespread as this problem is, I would think there would be a required recall for this service.

The front lights - water gets in impact visibility. The only repair is to replace the entire unit which is $2k per light. There is not other options. The adaptive warning sign does not go away due to this water.

While driving car stalled, dropped speed and engine warning light came on. Fuel pump was needed. Had to have car towed obtained a rental for 11 days. Fuel pump out of stock. Immediately after fuel pump was replaced less than two weeks the thermostat had to be replaced. Another tow and another rental. I need to be compensated for stress aggravation and loss of use. Repairs and car rental and tow cost over $3500
