Problems with 2005 BMW X3 STRUCTURE

When i turned on the driver's side seat heater, the seat heater burned through and burned a hole through my clothes

I'd unlocked my door and when i tried to close it, it wouldn't close like it should. it's like the actuator was stuck & wouldn't close. it does this for a few minutes of me cranking and turning off the ignition. finally, after i crank it up again, it just closes like nothing ever happened! i was stuck in a pharmacy parking lot for like 15 minutes thinking of how i was going to get home because my door didn't close! very, very inconvenient! i almost had to call a tow truck & would've been out of a couple hundred of dollars for this!!! why does this happen!!!?! this needs to be addressed and fixed! *tr

Our vehicle was stopped behind a single vehicle at a red light. without warning, the vehicle accelerated and struck the car immediately in front of our vehicle. after striking the vehicle, our car then accelerated again into the intersection and was struck by a vehicle moving legally with a green light through the intersection. our vehicle went to the curb where it accelerated once again which caused it to jump the curb and crash through a steel fence and into a light pole where it finally came to rest. there were three acceleration events with the driver's right foot off the gas pedal. the vehicle was deemed a total loss by the insurer, geico and was removed from service. *tr
