   The front driveshaft universal joint failed causing the drive shaft to bust a hole in the engine and crack the transmission. There was no knocking noise prior to failure. It suddenly failed, disengaged and caused damage. I was told by service manager the u-bolt must have been defective to have failed without warning.

   I am having issues with the starter motor / battery. I have read extensively about issues with BMW X5 models having recalls during the production period of my vehicle. BMW is trying to charge $3,000 for a new starter and battery. I feel that this is a known and significant issue with BMW X5 vehicles produced during the same period as my vehicle and would like for this to be covered under recall.

    In the middle of driving, multiple warning lights came on in the car and the steering became very stiff, which made it difficult to steer the car. We brought the car to the dealer service station and they identified that the crank pulley system had a failure and the vibration damper needed to be replaced. Apparently, this issue also resulted in the engine not properly charging the car battery, which also resulted in battery failure. This car only has about 38,000 miles on it…
