NHTSA lists 2 safety recalls and 345 owner complaints for the 2006 BMW X3. Most complaints involve air bags (177) and seats (54). The EPA rates it 17–18 mpg combined.
BMW of North America, LLC (BMW) is recalling certain 2006-2010 BMW X3 2.5i, X3 3.0i and X3 xDrive30i Sports Activity Vehicles. The front passenger seat occupant detection mat that determines if, and how, the passenger frontal air bag should deploy in a crash may fatigue and develop cracks which could lead to a system failure.
BMW IS RECALLING 200,000 MY 2006 3 SERIES SPORT SEAT, MY 2004-2006 5 SERIES STANDARD AND SPORT SEAT, AND MY 2004-2006 X3 PASSENGER VEHICLES. DEPENDING ON THE MANNER AND FREQUENCY OF THE FRONT PASSENGER'S ENTRY AND EXIT, SMALL CRACKS HAVE DEVELOPED IN THE MAT. IF THIS OCCURS, THE FRONT PASSENGER AIR BAGS, WITH THE EXCEPTION OF THE HEAD PROTECTION SYSTEM, WILL BE DEACTIVATED AND THE AIR BAG WARNING LAMP AS WELL AS THE PASSENGER AIR BAG "ON-OFF" LAMP WILL BE ILLUMINATED.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“1. The front passenger airbag light is continuously on. 2. Fasten seat belt audible alarm, and fasten seat belt dash light are continuously on when front passenger seat is NOT occupied.”
“I turned on my heated seat and within about a minute and a half I smelled a burning smell. Pulled over as I started to feel a burn on my leg because the seat heater has burnt through the leather in my car. This is a known problem at BMW and they have not issued a recall for this.”
“I can smell a burning smell at times coming out from my blower and the heat and air condition is not functioning properly. Also my rear hatch lights on the interior are always on and when I hit bumps they flash off and on.”
