2004 BMW Z4

When driving the steering is loose or sticky. The problem gets worse when the weather is warm. Sometimes it’s hard to keep the car driving in a straight path. This is scary and dangerous. His occurs whenever the car is driven. Other z4 drivers are having the same problem.

The steering sticks, in warmer weather, at freeway speeds. Continuously trying to unstick the steering wheel, with the possibility of overcorrecting, at freeway speeds, could present a safety hazard. Yes, the alignment company recognized the problem during their post-alignment test drive. The vehicle has not been inspected by "manufacturer, police, or insurance representatives." No warning lamps/lights/messages on dash. However, if you google 2004 BMW with sticky steering, you will find NUMEROUS accounts of this happening to other owners of similar vehicles (specifically 2003-2005 Z4).

The electric steering gets sticky when hot. It feels locked in its position and requires extra force to unstick, once its past the sticking point it over corrects and causes the vehicle to swerve. This failure seems to be quite common and is well known. It seems to be a manufacturing defect inside the electric steering column. I believe it has already been investigated by NHTSA but a recall has not yet been called to protect the consumer. This failure only happens when it is hot or the heater is on in the car, there is no warning before it occurs. Thank you for your attention in this matter. Please help by re-investigating this common failure.

The steering is sticky, like the steering system is locking up. It isn't smooth but instead very jerky, and requires serious effort to manage. It is becoming dangerous and is very unsafe. I have seen a lot of complaints on the internet and can not believe this isn't a recall item!

Component or system failed: Steering Column. It is available for inspection. Safety or the safety of others put at risk: When driving the steering column will lock or stick into place until it is forced back into a normal driving position. This consistently occurs when driving on a corner or making slight steering adjustments on a straight road. Has the problem been reproduced by a dealer: UNKNOWN Has the vehicle or component been inspected: UNKNOWN Were there any warning lamps: None

Steering is "sticky" with a feel of detents in the steering instead of expected smooth engagement. At highway speeds this is concerning and feels unsafe. Difficult or impossible to steer smoothly.

The contact owns a 2004 BMW Z4. The contact stated while driving at various speeds in warm weather, the steering wheel was difficult to turn. The contact stated no warning light was illuminated. The contact was able to park on the side of the road. The contact continued driving with caution to his destination. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 125,000.

The the vehicle sits out in the sunlight or its warm outside (usually over 80F) the steering wheel will get very notchy and “stick” towards the center position at highway speeds. This makes minor steering corrections at highway speeds very difficult to make without unintentionally leaving your own lane possibly into another car. This is very much a safety issue! This has happened on multiple occasions since the week after I got it in May 2022. Tonight its only 65 degrees and it was acting up (this is 2 hours after sunset).

The steering wheel is "sticky" and has play in it when you are driving it. It appears to have steering drift. I feel this car is not safe to drive and is hard to control. No warning messages have come on. When I searched online, it appears that many others are having trouble with their 2004 z4 steering.

The Electric Top Malfunctions because of fault design Behind the driver seat is a hydraulic cylinder that sits in a cabin. Water leaks into the cabin causing the hydraulics to go out. The cabin fills up with water, and submerges the pump. This is a major design flaw. It is common with all Z4 models 2003 - 2008. I have a roadster rental business, comprised specifically of the Z4 model. I can give you 4 different vehicles I own as an example. Plus I can quote every seller, that says the top does not work. If people are not aware of this it can lead to accidents, the claw hooks disengaging, unable to get the top up in a lightning storm, rain storm etc., I haven't seen any recalls on the tops. There are no warning lamps on the vehicle that indicate the top motor or its hydraulic cylinder are malfunctioning. Most of these tops quit working in the same year or a couple year after the car was purchased, from manufacturing date. My car, I have reported here, only has 75,000 Original miles.

I own a 2004 BMW Z4 2.5i I bought it used in 2010 with 22,000 miles. It was on a cool December day when I test drove the car and I loved it. No sign of any steering problems. On a warmer day after driving for a while I suddenly experienced a unexpected binding of the steering and almost binding ended up steering into oncoming traffic. This really scared me and I started investigating. Yes, this is a known safety defect, but BMW doesn’t do anything about it. NHTSA, which supposed to protect us from unsafe vehicles, did not do their job either. I am a retired Automotive engineer with Fiat-Iveco and NHTSA made my company recall vehicles for much less. The defect gets worse in hot weather and I don’t let my son, friends or anybody else drive the vehicle, as I am afraid that they could get hurt, aside from a liability issue on my side. I can’t really sell the vehicle with a known safety defect from a moral standpoint and I definitely would be liable should the car get involved in an accident caused by a known defect. BMW and NHTSA do your job before somebody gets hurt or killed! Doing nothing, will cost you more in Settlements and Reputation in a long run…the problem will not go away by doing nothing!
