I have experienced the steering does a notchy or “sticky steering” issue that is quite scary from time to time as I drive the car. I looked up and found this is a widespread problem with the BMW Z4 2003-2005 models. I see there was no recall for BMW to have to mandated recall these vehicles and fix this issue. I have had this car for a 17 months and experienced this on several occasions that catches me off guard as i am driving. I am dumbfounded that there was no recall for this issue. I writing you so that before someone gets killed that you issue an immediate recall on these cars. I should not have to outlay thousands of dollars for a fix that should been the manufacturers at BMW to fix.

Defect investigations
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 2005 BMW Z4 owners say
Most recent owner complaints, unedited.
My driver side seatbelt sensor suddenly would randomly detect no seatbelt despite being buckled and then the steering wheel airbag deployed into me while I was reversing the car under 2mph. I suffered burns and bruises, hearing loss, and disorientation from the deployed airbag. I could have broke my nose, or my wrist or fingers. BMW dealership refused covering towing and inspection. BMW airbags across multiple models and years have experienced recalls and issues. Seatbelt detection sensor blinked before airbag deployed into me.
While moving, especially in warm weather, the steering will stick. This requires excessive force to move the steering wheel which results in a "jump" when the steering moves (breaks loose). This sudden "jump" results in vehicle moving excessively, especially scary in traffic! I have not had the vehicle inspected by a mechanic but reading various forums this appears to be a common problem with BMW Z4s.
The contact owns a 2005 BMW Z4. The contact stated that after entering the vehicle, the heavy plastic interior liner panel fell on his head. The contact stated that the plastic cover was used to hide the windshield clasps that hold the convertible top in place when the convertible top was closed. The contact attempted to reattach the plastic liner however, the fasteners had fractured. The contact placed the plastic liner into the rear of the vehicle. The contact stated while driving, the rear view of the vehicle was blocked by the detached plastic liner. The contact stated that the convertible top was able to retract and return into place, but the convertible top attachment clasps and mechanism were exposed. The contact was unable to reattach the liner. The contact had not taken the vehicle to a dealer or to an independent. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was approximately 99,000.
The passenger air bag suddenly deployed while the car was parked in my driveway, braking the dashboard and the windshield.
Passenger airbag dash deploys while car is parked. It’s deploy from nothing.
Generally described as sticky steering. Steering wheel binds up and needs pressure to overcome, then released and the car overcorrects so steering is erratic. This is particularly dangerous when cornering. Issue seems temperature related and is worse in high temperatures. This is a well known problem in 2003-2005 BMW Z4. The car has been sittting in my garage for a year as it is unsafe to drive. When is the recall?
This 2005 BMW Z3 was bought from a dealer who sold the car to the original owner and maintained it. The car has 45,000 miles on it, and I am the second owner. I have only owned the car for one month. Yesterday was the first day of 80 degree weather, and the steering is now "sticking". 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. I have now read about others with the same problem, and that BMW is aware of its design flaw. There should be a recall issued for them to correct the problem. My understanding is that it is a costly repair, and it will most likely reoccur after the fix. Needless to say, I am very disappointed with the dealer as I feel they knowingly sold me this car with the steering problem. We are in the south, so warm weather for nine months out of the year is common.
While driving the vehicle will loose all power steering, and becomes very difficult to steer, warning lamp comes on with a steering wheel and a exclamation point. Has been diagnosed as needing a steering wheel column assembly.
The front headlight wiring harness is flaking off and could cause a short and lose your lights at night and cause a accident. there has been no recall and it's happening to all of the bmw cars that had this environmentally friendly insulation. It is a hazard because you can lose both headlights without notice and have a accident. It has been going on for years according to several mechanics I've spoken too. It also is a huge expense to replace.
