Owners have filed 143 complaints with NHTSA about the 2006 X3. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2006 X3 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
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.
Risk: Should the system fail, in the event of a crash, the front passenger air bag would be deactivated, increasing the risk of personal injury.
Remedy: BMW will notify owners, and dealers will replace the front passenger seat occupant detection mat, free of charge. Interim owner notification letters were mailed on November 27, 2017. A second notification letter will be sent when parts are available. Owners may contact BMW customer service at 1-800-525-7417.
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.
Risk: IN THIS SITUATION THE FRONT PASSENGER AIR BAGS WILL NOT DEPLOY EVEN IF A SUFFICIENTLY SEVERE ACCIDENT WOULD OCCUR AND OCCUPANT PROTECTION PROVIDED BY THE SYSTEM WOULD NOT BE POSSIBLE.
Remedy: DEALERS WILL REWORK THE FRONT PASSENGER SEAT SENSOR MAT SO THAT EXTERNAL FORCE APPLICATION TO THE SEAT DOES NOT CAUSE A CRACK TO THE MAT. THE RECALL BEGAN ON NOVEMBER 6, 2008. BMW WILL ALSO EXTEND THE WARRANTY ON THESE VEHICLES TO 10 YEARS FROM FIRST REGISTRATION WITHOUT ANY MILEAGE LIMIT. OWNERS MAY CONTACT BMW AT 1-800-525-7417.
Carmakers sent NHTSA 70 service bulletins and notices that cover the 2006 X3, the latest on Apr 4, 2024. They tell dealers how to fix known issues.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
