“Bought 2003 745LI new. Many problems from the start and often in for service. Driver side window motor quit working a year ago. Learned this is common with other blogs and Bmw owners. Current miles are only 70,000. Over the past year the engine has run extremely rough even having to stop the car because of it. Occasionally has been difficult to restart. After three weeks in their service center Bmw can't seem to figure out the cause but want to do $4500 of work in the engine while telling me they can't be sure that what they do will take care of the problem!?”

The vehicle lost power, and she was unable to restart the vehicle. It was towed; the failure mileage was 10,000 miles. In 2006 while attempting to start the vehicle the transmission disengaged, the radio was on, and the vehicle was out of control. The vehicle was at the dealer for 4 to 5 days in order to update the software. On another occasion, the shift control fell off the vehicle. The dealer stated that the vehicle was repaired, and the contact didn't feel safe driving. …”

The dealership told me it was a design feature. I moved out of the state and contacted a dealership in the corpus christi, tx area about the continuing problem. Over the past year I have had several occassions when the stalling was such that the car would fail and place me and/or my family in near accidents. …”
NHTSA complaint #10079062, filed 2004-06“The contact owns a 2003 Bmw 745LI . The contact stated that the alarm would activate on its own. In addition, the air bag and seat belt warning lights would illuminate on the instrument panel for no reason. The navigation system would flash on and off as if there were an electrical short whenever he would stop the vehicle or depress the brake pedal. The dealer would not make any repairs because the warranty was expired. The failure and current mileages were less than 80,000.”
