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 2003, the first year the car was on the market.

Sticky Steering
ODI has evaluated the sticky steering condition, which included reviews of complaints and warranty claims, interviews and surveys of owners of complaint vehicles, road tests of complaint vehicles, and a review of BMW's engineering and test data.ODI found the sticky steering condition does not result in a significant steering effort, thus the impact on the driver's ability to control the vehicle does not appear to be significant.A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.See the attached report for additional information.In addition, during this investigation, ODI became aware of allegations of failure or loss of electric power-assisted steering on the subject vehicles.As a result, ODI is separately reviewing this issue to determine whether additional agency action is needed.

What 2003 BMW Z4 owners say
Most recent owner complaints, unedited.
Steering is binding up, very hard to steer and control. Car starts out running fine after parked in hot weather and restarted it is almost uncontrollable. Looking for corrective action. Only 39,920 miles on car. Would like to use it or sell it, can do neither in current condition. Steering column needed or components
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 could not control. I used "more force" to pull the steering wheel to get tracking correctly and stay in my travel lane. Lucking I did not overcorrect and lose control or cause and accident. Once it happened it continued to happen the balance of the drive on the highway and back roads. I've owned and driven many different makes and models of vehicles from Dodge, Renault, Toyota, GMC, Chrysler, Volvo, Geo, etc. and never has "steering" been an issue. Once we got home I looked up "sticky steering" issue for the 2003 Z4 and this is a known issue. Driving this BMW was unsettling and unsafe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Upon starting the car, power steering does not work making car unmanueverable.
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 go off the road. On a warmer day after driving for a while I suddenly experienced a unexpected binding of the steering and almost ended up steering into oncoming traffic. This car is not safe to drive. The 2003 model has electric power steering. There are no codes or warning lights. I took the car to the local mechanic and he was easily able to reproduce the issue when he drove it less than 1 mile. This issue not only puts me at risk but others because of the constant correction of the steering to keep a straight. If you drive this car in warm or hot weather distances more than 20 miles then shut if off, then attempt to restart there is no steering at all. Please view the 2 websites listed below from BMW owners. https://automotivesblog.com/e85-e86-bmw-z4-steering-problems-how-to-fix/ https://www.carproblemzoo.com/bmw/z4/steering-problems.php One website had almost 700 complaints with the steering. I dare not let my kids behind the wheel of this car. It is not a question of "if" someone gets killed, but "when." BMW North America would only say there are no recalls. When I asked if there have been issues reported, they declined to give me that information. Please help. It would be interesting to know how many accidents were listed with the steering being the cause of the MVA. I would gladly allow someone with the federal safety agency drive this car in warm weather. Then you would see how dangerous the steering is in these vehicles.
Sticky steering steering wheel hard to turn and stops intermittently when outside temperature is hot
Sticky steering after car warms up. Steers like a boat. Dangerous at highway speeds or winding road.
The contact owns a 2003 BMW Z4. The contact stated while driving at various speeds in hot weather, the steering wheel became difficult to turn and would also jerk the vehicle into the next lane. The contact stated no warning light was illuminated. The contact was able to drive to the residence. The contact took the vehicle to the local dealer, where it was diagnosed with needing the battery to be replaced. The dealer replaced the battery however, the failure recurred. The manufacturer had been informed of the failure. The failure mileage was approximately 24,000.
During very warm days in the summer the steering wheel tends to stick during turns. It requires extra force to continue to turn the wheel which becomes problematic during a tight turn or on highway on-ramps.
