2003 BMW Z4 recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. ON CERTAIN PASSENGER VEHICLES, UNDER CERTAIN ENVIRONMENTAL CONDITIONS, A VAPOR LOCK IN THE FUEL PUMP COULD OCCUR CAUSING THE ENGINE TO STALL. IF THIS WERE TO HAPPEN, THE ENGINE WOULD NOT BE ABLE TO BE RESTARTED FOR APPROXIMATELY 15 TO 20 MINUTES.
What could happen: IF STALLING WERE TO OCCUR, THE DRIVER WOULD BE UNABLE TO MAINTAIN VEHICLE SPEED OR ACCELERATE, INCREASING THE RISK OF A CRASH.
The fix: DEALERS WILL INSTALL A RESISTOR IN THE ELECTRICAL LINE POWERING THE FUEL PUMP IN ORDER TO PREVENT AN OCCURRENCE OF VAPOR LOCK. THE RECALL BEGAN MAY 11, 2004. OWNERS SHOULD CONTACT BMW AT 1-800-831-1117.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2003 Z4.
- Book a repair at any authorized BMW dealer. Quote NHTSA campaign 04V182000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-831-1117.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

2. Wheels / tires
What's wrong, in plain English: A wheel or tire can fail while driving. ON CERTAIN VEHICLES EQUIPPED WITH 18" TIRES, IT IS POSSIBLE THAT THE TIRE HAS BEEN DAMAGED DURING THE MOUNTING PROCESS TO THE RIM.
What could happen: CONSEQUENTLY, A LOSS OF TIRE PRESSURE, OR A TIRE FAILURE, COULD OCCUR. DEPENDING ON TRAFFIC CONDITIONS AND THE DRIVER'S REACTIONS, THIS COULD LEAD TO A CRASH.
The fix: DEALERS WILL UNSEAT THE TIRE FROM ITS RIM, INSPECT FOR ANY DAMAGE, AND THEN RESEAT THE TIRE TO ITS RIM. IF INSPECTION REVEALS THAT A FRONT TIRE HAS INCURRED DAMAGE DURING THE MOUNTING PROCESS, IT WILL BE REPLACED. OWNER NOTIFICATION BEGAN JULY 14, 2003. OWNERS SHOULD CONTACT BMW AT 1-800-831-1117.

4. Seat belts
What's wrong, in plain English: Seat belts may not hold you in a crash. ON CERTAIN PASSENGER VEHICLES, THE CONNECTION OF THE SAFETY BELT BUCKLE TO THE STEEL ROPE OF THE TENSIONER DOES NOT MEET BMW SPECIFICATIONS. IN SEVERE FRONTAL CRASHES, THIS CONNECTION CAN DETACH.
What could happen: IF THE CONNECTION DETACHES, THE PROTECTION PROVIDED BY THE SAFETY BELT IS LIKELY TO BE IMPAIRED, AND SERIOUS INJURIES TO THE DRIVER AND/OR FRONT PASSENGER COULD OCCUR THAT MIGHT OTHERWISE BE MITIGATED.
The fix: DEALERS WILL INSPECT BOTH FRONT SAFETY BELT TENSIONER AND BUCKLE ASSEMBLIES, AND IF NECESSARY, REPLACE THESE PARTS. OWNER NOTIFICATION BEGAN MARCH 19, 2003.

This vehicle has a "sticky steering" issue in warm or hot weather, the steering sticks and requires a lot of effort to get the wheel to turn. If I am doing any speeds over 40 mph and keep adjusting the steering, I have almost wrecked the car on more than one occasion. The problem is the electric steering on the early year models of the BMW Z4. Mine is a 200…

When outside temp is 80degrees or higher it becomes difficult to maintain the vehicle in the correct driving lane due to a stickyness in the steering wheel. I will not allow anyone to drive the vehicle when the temp is over 80 degrees ... sucks to have a convertable that you can't drive in warm weather!

My girlfriend, [XXX] , purchased a used 2003 BMW z4 2.5i. It is pristine with 47K original miles. Always maintained, garaged and never driven in foul weather. I, [XXX] , drove it home for her and noticed the steering to be "sticky". This showed on the highway traveling at 65 MPH. It was very unsettling to feel the car want to track in a direction that i co…

The steering in this BMW Z4 gets "sticky" in warm or hot weather. It drives fine in cold weather. The steering has to be constantly corrected as it pulls to the left. It will not track in a straight line and needs constant corrections from side to side to compensate for the problem. If you do not pay close attention and correct the steering input, you will…
