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.
Passenger external front and rear door handle assembly caught on fire and melted the rubber grommet. BMW said it was the comfort sensor fuse that should have blown but it did not. The rubber grommet holding the door handle melted. I had to buy two door handles that cost $250 each to replace the ones that burnt out.
Ever since the rain starter my aux water pump don't work and brake light too. And it seems like something has been draining my battery because battery discharge comes up. And I think the idle idle pulley issue affects almost most of that year bmw X5 because my serpentine belt only installed 10,000 miles ago and already see threads being worn out. Unless that's how long they last. I had to bring the car back in multiple times to get it adjusted because kept making squealing noise. They blamed it on water pump and didn't change the thermostat. Water even leak into front passenger side where all the fuses were. When I connected the battery charger I could hear the pump all of sudden working and the radiator tank sputter water out. …
I own a 2012 BMW X5 that is experiencing a Footwell Module (FRM) failure. BMW issued an Extended Limited Warranty for the FRM extending coverage to 15 years or 186,000 miles. My vehicle falls within those limits. The FRM failure has rendered the headlights, high beams, turn signals, brake lights, and power windows inoperative. As a result, the vehicle cannot be safely operated on public roads. Other motorists may not be able to see when the vehicle is braking or turning, creating a significant safety concern. BMW of Brooklyn and BMW of North America have informed me that I must pay a $360 diagnostic fee upfront before they will determine whether the repair is covered under BMW's FRM Extended Limited Warranty. BMW's warranty letter states that the FRM warranty is subject to the same eligibility requirements and limitations as the BMW New Vehicle Limited Warranty. …
Front passenger door would not unlock or open from inside or outside. Per dealer and report this appears to be failure of the passenger door actuator/solenoid. Door panel will require removal to confirm. There was no immediate safety issue, however with 3 small children, there is a reluctance to drive this car with the potential for doors locking and no way to extricate them should the problem occur on all doors. My understanding is there is no mechanical release associated with these doors. In addition, if an elderly/handicapped person had been in the front passenger seat during this occurrence, there could have been serious issues with extrication. I have been an engineer for 30 years and liken this problem to the old refrigerator doors latches trapping children inside and similarly, rear trunk latches with no interior releases. I have notified the manufacturer and reported this issue.
The contact owns a 2012 BMW X5. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated.

The failure was intermittent. The contact later received an extended warranty notification for the foot well. The vehicle was taken to the dealer where it was diagnosed with a misfire in cylinders #3 and #4. The contact was informed that the failure was not related to the extended warranty program. The contact was informed that ignition coils and plugs in cylinders #3 and #4 needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.
Vehical randomly shuts off, it all safety systems warning lamps come on l, like ABS, Airbag, and traction control. Found wiring harness laying in a pool of water in the rear right cargo compartment. Rain water leaking from sunroof collected in compartment. The harness contains wires for the the vehicles CAN buss systems the water causes corrosion in the harness, which causes all sorts of problems that could happen at any time like the vehicle shutting off or the airbag or abs warning light coming on.
I was using the seat heating on a very cold day recently and 10 minutes into the drive we noticed a weird smell, but couldn't locate the source. As the smell got worse and worse over time, we stopped the car, turned of the interior lights and saw that smoke had accumulated in the cabin, suddenly we found that the seat heater had burned a hole through the leather seat on the rear passenger side, where my girlfriends father sat .
Water entering into the vehicle, causing vehicle to reduce power in traffic, due to traction control issues.. Not able to drive vehicle when it's raining., along with other issues, pls see first report..
