One problem related to software has been reported for the 2011 BMW X3. The most recently reported issues are listed below.
My vehicle suddenly lost power steering control and a yellow warning symbol appeared on the instrument panel. I experienced the problem the first time while I maneuvered a corner. I was coming out of the turn and accelerating when the steering locked up, and the loss of steering control almost caused me to crash. I took the car immediately to murray motors (in denver, CO) and was advised that there was simply a computer programming "glitch" that came from the factory; the service center advised they downloaded new software and the problem was solved. Some weeks later, I again lost power steering suddenly while driving straight. I took the car into murray motors again and stressed the enormity of my concern over this frightening problem. After some days, murray motors advised me that the electronic power steering assist unit had failed. They represented they replaced the power steering rack, the electric motor mounted on the rack, and the eps module. I researched BMW recalls thereafter and found that a recall had been issued for this problem on several BMW models already. I called BMW's customer relations number (1-800-525-7417) and was informed that my vehicle VIN number fell outside the scope of the current recall, and I was therefore never notified. I am writing the NHTSA to report that BMW's recall is not broad enough as defects in the eps module and related parts exist in vehicles beyond the immediate recall. I also want the NHTSA to know that murray motors allowed me to drive this vehicle out of their service center after the first (inadequate) repair, even though the steering complaints I reported to their service technicians were identical the description of the steering problem listed in BMW's recall letter for the X3 posted on their website. Murray motors claims to have no knowledge of this defect in any X3.
