The steering pseudo-locks (has a "tick") and its nearly impossible to hold the vehicle straight. One is continually fighting the steering tick/lock to keep the car going straight.

On hot days, the steering on my BMW "sticks." This is becoming more and more of a problem. I just drove the car home from the mechanic on a 60 mile trip. The problem causes me to have oversteer and over-correct when changing lanes. It's increasingly difficult to maintain control of the vehicle. Furthermore, I now drive with my forearms completely tense in an attempt to compensate for the problem which results in undue fatigue. My mechanic suggested tat the only remedy is an entirely new steering rack, in excess of $2,000. The car only has 52,000 miles though it is out of factory warranty. A quick search online, indicates that this is a common problem. The problem has been occurring for some time (at least 25,000 miles) but I'm beginning to feel at more and more of a risk. I mentioned it to the dealer when it first began happening, while the car was still under warranty, but they told me nothing was wrong.

Same issue as described in NHTSA investigation PE 10-020 "sticky steering" occurs during periods of high ambient temperatures. The car darts and wanders. It is extremely disconcerting and requires constant attention. An increased steering effort typically occurs when the steering wheel is at the center position and thedriver attempts to make small steering adjustments. This is not a one time incident so "approximate incident date" is inappropriate. It is constant. Also not sure why the investigation you conducted lists only '03-05 when it clearly states in the investigation that BMW did not fix the problem until July 2006. My car is a 2006 with a June 2006 build date, just prior to the fix of the acknowledged problem.

2006 BMW Z4 3.0si electric steering system requires repeated corrections to stay going straight down road. It's as is it will only steer 3 degrees or more in each direction, but never in 1 degree increments. This only happens on very hot days after being parked outside in sun.

- Houston, TX, USA

In hot weather (over 90 degrees F), after sitting in the sun, steering will bind or stick when turning. It requires more force than normal and does not return to center as easily. This makes it difficult to take corners smoothly. Situation gets better as car interior cools.

The steering in my car seems a little odd at speed. The car wants to sway back and forth when traveling in a straight line. I thought it my be the road conditions but I am not totally convinced that the steering should be bad enough that you many need to slow down in order to make the necessary steering corrections at speeds of 70 mph. I know for a fact that others are experiencing the same issues as me as O have read post after post to the problem while looking for solutions. I have tried buying new tires and that seems to cut it down some but it did not get rid of what some call tramlining. I am calling it swaying as I may not know the correct terminology. I hope that you investigate this issue so that we can truly find the issue so that a fix can be put into place so that these cars are more safe.

I have had a recurring serious problem with the steering input effort, especially when hot outside. The steering seems very heavy and sticks when close to the on-center position, and is very heavy and difficult to return back to the on-center position. It is a problem that has been a concern for my wife and I now for several months. The vehicle has been in and out of service very frequently since April of 2010. It is in service for the forth time now regarding the problem with the steering. The vehicle this time has been in now for almost a month and has not been repaired yet.

Today I experienced a steering problem with my 2006 BMW Z-4. the outside temp was approx 86 degrees. I noticed the steering (which is electronically controlled) became very heavy and it became difficult to maintain the vehicle in the lane. Twice the vehicle jutted to the right causing me to ride on the edge of the road (hitting the grinders) - it took both hands and a tight grip to maintain center. I first noticed this problem last summer - steering is normal at cooler temps but today it was hot outside and the problem recurred. I took my vehicle to the dealer last summer and they found no fault codes, but this is a definite problem and BMW is very aware of it.

BMW 2006 Z-4 3.0 si power steering unit failed to operate at vehicle start up. The car was taken to the local BMW dealer (BMW long beach ca) where the failure of the power steering unit was confirmed by the mechanic. After inspection of the unit by the dealer the unit began to operate with no further faults found, an additional three days of testing and troubleshooting by the dealer failed to identify or repeat the original fault with the unit-- no parts were replaced.

This concerns many BMW Z4 eps (electronic power steering) when the car set in hot weather and then I go to drive it, the steering becomes very tight and does not always return to center. Also there is a lag in steering turning or null spot of almost no response for up to one inch of steering wheel turn. This tight slug est response to is totally opposite in cool weather when there is no problem in steering response.
