Three problems related to wiring have been reported for the 2008 BMW X5. The most recently reported issues are listed below.
Vehicle shut off while stopped. A smell of hot electrical was present immediately before the shut off. Inspection of the vehicle showed a blown fuse for the fuel pump circut, as well as melting of the plastic power connection to the fuel pump, and the insulation on the power wires themselves. The bare wires were exposed at the connection. The wiring harness was stiff from the connector of the fuel pump to the rubber seal on the body.
The 2008 X5 3. 0l started to sound like a jet engine with the super loud fan noise. I thought the car was going to blow up. Took the car in for repair, and luckily the engine hadn't overheated yet. They found that the water pump was faulty, which caused the wiring to burn out, and observed oil leakage near engine. If I had driven the car any more, it would have caused significant damage to the engine of the vehicle. BMW service center told me that I have to replace the water pump, thermostat, and other parts including gasket something. Thank you.
After the check engine light came on we took our vehicle to a local shop conway motors in everett, wa. Conway motors diagnosed the problem as a fuel pump and the wiring was burnt connecting the fuel pump. Mark at conway motors called BMW to see if there was a recall and was surprised when BMW parts in seattle stated there was not a recall but they were familiar with the problem and there had been other similar complaints with burnt wiring connected to the fuel pump. Mark advised we could not drive the vehicle and we were lucky the vehicle had not exploded. My wife drives this vehicle daily to work and BMW is aware of the issue but has not done a recall is totally unacceptable and put my wife's life in danger.
