In July my car was short of oil and the following parts were replaced cyclone seplerator with updated kit and replaced separator with updated parts including dipstick tube. Had oil changed on 9/16/11, on road at 2:00 a.M. in the morning and the oil level low light came on again. Had to pull off the road for fear of perm. Damage to engine. In town where there were no stores open to buy oil, I though the oil leakage situation was taken care of. Added 1.5 quarts of oil, returned home to take it back to dealer with the mileage 69731 and it was a quart short. They stated there were no leaks and I was informed per sib 110584 1 quart of oil is allowed to be consumed per 750 miles. I informed the dealer this car never consumed oil before. Had I known that it consumed oil I would not have paid $1308 to replace the parts. I would have traded the car. Very disappointed and this could be dangerous.

BMW X5 accelerator failed to respond after stop at traffic lights. It moved forward slowly for about 20 yds. Before deciding to engage...this happened three times, consecutively, at the end of drive home. Around noon on Tuesday October 14, 2008. The day before the internal door lock button failed to function. Called BMW dealership and had it towed. BMW continue to test but was informed last evening that there appeared to be nothing wrong with vehicle according to the computer! this is a major safety issue and BMW [central] have not been supportive so far. I have asked that the car be fixed and that I be supplied with a loaner until then.
