If the car is left in the sun or is used on a hot day (seems to be above 85F degrees), the steering wheel is very heavy and "sticky" +/- 5 degrees off center. The car will not travel straight without constant correction and the steering wheel feels locked without extra effort to move its position. Driving the car in this state is unnerving and unsafe. It has led to multiple overcorrection on public roads when attempting to turn the wheel due to the extra effort. BMW na has not acknowledged a defect and will not attempt to correct it.
2003 Z4 3.0I has become unsafe with increases in steering sticking and notchiness. To make matters worse the symptoms vary with ambient temperature so the overall steering feel will vary from morning to noon to night.
The contact owns a 2003 BMW Z4. While driving 60mph his vehicle shut off in traffic. The road conditions were not a factor. The vehicle was accelerating at the time the engine shut off. He was able to maintain control of the vehicle but there was no power steering and the brakes failed. It became was very difficult to steer the vehicle. There were no warnings prior to the failure. He was able to operate the vehicle normally after 20 minutes. The following day when the vehicle started there was a bubbling noise in the engine area that lasted for approximately 2 minutes. No problem. The dealer and manufacturer confirmed that the vehicle was not a part of the recall. He was also advised that he would have to pay $152 for a diagnosic check. The failure mileage was 41,000.
The contact owns a 2003 BMW Z4. While driving 70 mph in hot weather, the steering binded and made it difficult to switch lanes on the highway.

The manufacturer advised him to take the vehicle to the dealer. The current mileage was approximately 48,000 and failure mileage was approximately 6,000. Updated 10/14/08 updated 10/23/08.
Vehicle has electric power steering. Intermittently, and without warning, power assist unit fails. Consequently, driver must use a firm grip and substantial force to control vehicle, especially at slower speeds. Unit fails either at engine start or while driving. Vehicle has only 45,000 miles. Steering torque fault was cleared during diagnostic check by independent BMW technician but fault has since recurred. Nearest authorized BMW service center also has checked vehicle. Owner was informed that fix would require replacement of upper steering column at cost to owner of $2,360 plus diagnostic fee. BMW North american contacted for assistance. They, in concert with the dealer, declined to offer any financial assistance to owner to replace defective components. Problem remains unresolved. Owner feels this vehicle has a defective part which creates a significant highway safety risk, especially to those unsuspecting of the potential fault. Date of incident below is first occurrence of problem, while owner was pulling into a parking spot.

My vehicle is a 2003 BMW Z4. The 'eps' electric power steering seems to bind on hot days. This could result in a collision and to date BMW is not fixing the problem.
Sticky, grabby, tight steering. No correction to center. Heavy feel and notchy. This problem occurs on hot days, especially after the car sits in the hot sun for a couple hours. Most noticeable driving at highway speeds. After sitting overnight, in the morning when it is cool, the steering is fine.
The steering is "sticky" when driving with interior heater on full/hot. If car interior temps cool down the problem goes away. I have to over steer to get the car to move in the direction I want and this causes a safety concern as the car will move too far in that direction. This issue is known to BMW and other owners.
Auto was exhibiting a knocking sound when approaching a full lock position. Dealer upon second complaint replaced the "lower steering column joint assembly part # 32-30-6-769-265". after the parts replacement the steering of the car has been noticeably impaired and exhibits steering that is very vague and exhibits a looseness on rough roads or during sharp turns such as parking or a U-turn. Dealership states that there are appropriate technical bulletins but chose not to release information in them. Car is parked awaiting BMW regional technical service inspection.
Growing steering difficulties with 2003 BMW Z4 purchased new. Dealership acknowledges there is a problem and says BMW is trying to determine a fix (this was months ago). BMW says sorry - refer to dealership, I believe this is a serious potential safety hazard which should be investigated for possible re-call.
I previously submitted a complaint with confirmation number 10135197. Since submitting that complaint, I have been on BMW related message boards and discovered the problem with high temperature "sticking" steering on 2003 BMW Z-4 roadsters is not only well known to BMW, but they have come up with a repair. Unfortunately, BMW is not recalling, not notifying and they are insisting that a car owner wait until a complete part failure that can be verified at the dealer to take any action under the car warranty. This problem comes and goes with outside heat. A dealership is not always around to verify the issue. I have talked with BMW usa headquarters in New Jersey and they throw me back to the dealer. If you took what BMW usa says at face value, they have no control over this issue. That is not turning out to be the case. Unfortunately, the dealer says they cannot act without BMW authorization and that requires the replacement of a verifiable failed part. The dealer is caught in the middle. There has been nothing but double talk from the people in New Jersey at BMW headquarters. The internet postings on this problem indicate how severe the issue is. The problem is world wide on 2003 Z-4's. it occurs in high outside temperatures and can, according to some postings, come on with no notice at high speeds. One driver described how he narrowly averted putting his car into the center divider of a highway. Feel free to check these boards, one of them is "roadfly.com" where a whole thread exists to discuss this problem. Another is "Z4um.com." Apparently the entire steering column must be replaced with one updated from original specs. The part number is 32-30-6-766-486. It is dangerous, unsafe and a risk of life for people to be driving these cars when the steering wheel handling hardens and control of the car is placed in jeopardy. BMW should be required to recall all of these cars and replace the defective part with the improved one.
Car sat in hot sun all day. Entered car to drive home and noticed steering was hard as speed increased upwards to 30 mph. As speed increased steering became very hard, requiring torque on steering wheel. At a stop the steering was normal, wheel could turn as always. At higher speeds up to 55 mph, when car wheels turned, the action was "choppy" or in increments rather than smooth and with the precision car normally had. It almost seemed like heavy weight on front of car. Checked run flat tires. No problem. Parked car at home. Two days later took vehicle to dealer and steering was normal. Dealer recognized a problem. Had same year and model with similar problem occurring daily. Could not duplicate the problem. Told me factory service bulletins said do not replace parts unless problem duplicated! dealer suggested I drive car until problem returned and then bring it in. They would do nothing until they could duplicate problem to perform diagnostic. Dealer not open 24 hours a day, other cars at same dealership with problem. Car was unsafe to drive when problem recurred. According to dealer, manufacturer is aware of problem, has technical bulletin out, but no parts replaced until failure occurs at dealership. Car being parked in sun by dealer to see if problem will duplicate. Car unsafe to drive!!! other cars there, same model and year with same problem.
Car was parked uncovered for about eight hours each day during a one week period and upon retrieval of the vehicle steering was noticeably malfunctioning. It was stiff and required excessive pressure to turn. A couple of days it had more of a notchy feel and would turn in increments with additional pressure.
1. hot ambient temperatures (roughly plus 85 degrees Fahrenheit) with the car outside in the sun all day preceding my drive home after work. This has happened on 5 occasions. The last occasion, prior to filing this report, is the date used below as the incident date. The previous occasions were each of the preceding 4 business days. 2. steering control is difficult and uneven causing problems keeping car on intended course of travel. 3. appointment scheduled with dealer for 7/11/05.
I have a 2003 BMW Z4 2.5I on Wednesday June 9, 2004 the ambient temp in ct was in the mid 90's while driving my car the steering felt like it was binding, was stiff to turn and did not automatically return to a center position. The steering lost the smooth gradual rotation as I turned the wheel the following day when the temperature was cooler the problem did not repeat itself.
The vehicle was turned off to fill with gas, when the vehicle was turned back on, the steering had gone out. The dealer had replaced the steering column gear and reprogrammed the eps and the lws with the cip V 7.0. mr scc
