At ambient temperatures above 75 deg the steering gets stiff and feels sticky. After making a turn the wheels do not return to the center position on their own but require driver to turn steering wheel back to center. Driving in a straight line requires constant correction because the steering binds and causes the driver to oversteering in order to overcome the stiffness.

Steering wheel sticks (still does as of March 30, 2013) and vehicle becomes hard to steer and control, especially when the weather is hot.

I have a 2003 BMW Z4 2.5I I recently purchased. I noticed the "sticky" steering for the first time the night I purchased it. After searching the internet I discovered that hundreds of Z4 owners have this serious steering issue. The steering is not so bad in cool weather, but warmer temperatures have an adverse effect on keeping the car on the road. I have had this issue numerous times in the 1 month that I have owned the car. Yesterday I almost lost control going down the highway on a curve driving at the posted speed limit. Z4 owners are afraid to drive the car due to this sticky steering issue. I didn't have to look hard on the internet to find that this issue wide-spread and has been grossly ignored. I was also surprised at the number of affected cars, with no action by BMW or our government. What are the powers at be waiting for" a death because of the steering issue. The car needs a recall for a replacement steering column or a bulletin to simply bring the car to a dealer for a replacement at no cost to the owner. BMW is aware of the faulty steering columns. Why has this not been fixed yet" please do something!

The steering feels 'sticky'. driving at roadspeed, esp on interstate where you're trying to maintain straight line, when you need to make slight steering adjustments, the steering sticks and when you give it enough effort to 'unstick' it, your car moves erratically. Basically, when it 'unsticks' it causes the driver to over-correct and oversteer. It does this when the car has been sitting in the sun on warm days, I.e outside ambient temps over 80 degrees F.

Power steering broke down. I read a lot of complaints online trying to research what kind of experiences other owners had and there are too many issues with steering with these cars to be ignored. Thank god that my power steering stopped working at a low speed, but what would happen if I was traveling at 70 mph? I had "sticky" steering in this car for years but this took it to another level. This issue should have been recalled.

Steering wheel goes back & forth on its own at highway speeds. Very scary ! not safe! feels like there is no control. I paid a lot of money for the ultimate driving machine that I am afraid to drive.

Steering wheel sticks then releases causing loss of control.

Driving South on santa barbara attempted to turn right onto davis blvd. As I was turning the steering stuck. That surprised me and almost lost control. It took a heavy effort to correct the direction of the car.this problem seems to occur at high ambient temperatures.

The power steering becomes dangerous when the car is exposed to heat 80+ degrees/sun. The steering wheel "sticks" in certain spots and is hard to move. It will randomly stop "sticking" giving an unexpected push in any given direction. Looks to be a frequent complaint. Car is unsafe to drive in the heat.

BMW Z4 steering - no power steering, causes difficulty in managing & steering car.

- Mansfield, TX, USA

There is a catch or binding feeling in the steering after the car has been driven a while and is at full operating temperature (gets worse when warm). I noticed this after having driven it a few miles; it feels like the car wants to track on its own as if it was following a rut in the road even though it is on smooth pavement and the wheel has to be forced back in the a straight line. It happened to me as I entered an intersection and the steering stuck, turning me into the on-coming lane. I worry that this may happen when my wife is driving and result in an accident if it were to tighten up unexpectedly.

On my drive home from work, after the car had been parked outside, I experienced "sticky steering." Just like the complaints from investigation PE10020 and countless internet posts over the past decade, the steering wheel movement was stuck in place and required extra force, then it would release unexpectedly causing me to over-correct. Worse than just heavy steering is the fact that it needs extra force to get the steering wheel "unstuck" but then the assist kicks in and you're over-compensating which causes zig-zagging. It was almost impossible to maintain my lane on the interstate and at one point I dropped two wheels on the shoulder. I have now contacted BMW corporate and they tell me they're being generous by replacing the known-faulty steering rack -- so long as I pay $1,000+ in labor. I think this is outrageous. It is wrong that this known defect costs the consumer any money to replace. BMW should cover parts and labor. They know this part is faulty, everyone I've talked to says "oh, the Z4, yeah I've seen this steering problem on lots of them" but they're quick to remind me that it was not an official recall so they aren't obligated to do anything. This is a safety issue and should be the basis for a mandatory recall (you know, like the one they are doing on current models with similar power steering failures!).

Sticky steering causes over steering.

- Chiefland, FL, USA

The contact owns a 2003 BMW Z4. While driving approximately 45 mph, the steering wheel exhibited excessive play which caused the vehicle to travel out of its lane. The failure recurred whenever the vehicle was in operation. The vehicle was taken to an independent mechanic who stated the vehicle operated normally. There was a front end wheel alignment performed and all four tires were balanced. The failure continued after the repair. The contact planned to have the vehicle inspected by a different mechanic. The manufacturer was notified of the problem. The approximate failure mileage was 54,000.

The contact owns a 2003 BMW Z4. The contact stated that while turning at 5 mph, the steering wheel seized. The steering wheel became stuck in the centered position and made it very difficult to change lanes on the highway. The failure occurred frequently at all speeds. The vehicle was taken to a private mechanic that specialized on BMW manufactured vehicles. The mechanic diagnosed the failure and stated that the repairs would be very expensive. The vehicle was not repaired. The dealer was not notified. The manufacturer was not notified. The failure mileage was 87,000 and the current mileage was 87,300.

Driving 35 mph straight. Lost power steering. Pulled over shut off engine. Restarted engine power steering returned. Lost power steering again within one mile. Returned home.

The steering seems to lock up making it hard to steer. Seems rather dangerous since you have to move the wheel hard either to the left or right. Wondering why there isn't a recall on this.

- Kettle Falls, WA, USA

The vehicle was parked in the sun with temperatures over 88 degrees. At 2 pm, I drove the vehicle on the highway at 60mph while rounding a slight bend to the left. The steering wheel would not turn under a slight effort so I made an additional effort. Suddenly, the resistance is completely absent resulting in a sharp veer to the left changing lanes. Fortunately, there was not another car in the left lane. I immediately corrected and returned to my original lane. Within 15 to 20 seconds, the situation repeats. I tried turning on the sport feature which is suppose to provide more resistance but the same event occurs. It only happens in hot weather when the vehicle is sitting in the sun for 4 or more hours and it is above 88 degrees. In order to compensate, I drive in one gear lower, say 4th, and constantly shimmy the wheel to avoid loss of control. It's similar to snow skiing with the vehicle catching an edge or groove it does not want to get out of. It continues to drive in the same previous direction as you apply additional effort. Suddenly, the wheel gives and it's as if the power steering assist is suddenly amplified, what you would normally need at 5mph, not 60mph. As you finish the bend, it continues to stay locked in the turning position. So, additional effort must be made to straighten out the vehicle and again the steering wheel fights your efforts only to suddenly give when you least expect it. You struggle to keep the car in your lane the entire time and from the rear, the vehicle appears erratic and swerving from side to side. That was my first summer with the car and it is currently at the dealer where hopefully my extended warranty will apply.
