Passenger interior Door handle assembly caught on fire and melted the rubber grommet. BMW said it was the comfort sensor fuse should have blown but did not. I saw blue smoke while driving from the passenger door mirror blowing out of the door handle like a volcano for 2 ft sideways. The rubber grommet holding the door handle melting completely down the outside door exterior. BMW fixed the sensor but my entire electrical system has been a disaster since. the passenger seat air bag warning, the parking brake, sensors working intermittent in the vehicle. There is a problem there should be a recall on the entire electrical system.
