| Seat Belt problems |
The driver's seat belt is locked and the retractor is not working without any reason. The front adaptive cruise control radar is also not working, along with the crucial blind spot sensor. Because of this, the vehicle cruise control (even without adaptive mode) is not working at all. This is a big safety issue and it is illegal to even drive this car without the seat belt working.
Seat belts will not extend. When trying to buckle seat belt, the belt retractor locks as you try to extend, preventing you from buckling your seat-belt. Affects both driver and passenger seat-belts. Intermittently happens and seems to be temperature related. More likely to happen when it is warm.
Seat belt on the driver side will not pull out to latch, I have taken it to the dealer five times over the coarse of 2. 5 years and they say "this is normal for this vehicle", my wife had to drive the car with no seat belt.
