What owners report
Complaints on this model year are dominated by a binding, notchy steering feel that many owners connect to warm weather and that appears across a wide spread of odometer readings, from a few thousand miles to well past 100,000. The remaining complaints are scattered across airbag warning lights, electrical warnings and other one-off items. No recalls are listed for this model year, so owners describe mostly diagnosis and out-of-pocket repair.
- Steering
Sticky or binding steering, worse in hot weather
- 169 complaints (88%)
- median 47,000 mi at 8.3 yrs old (155 state mileage)
- 2 mention a crash, fire or injury
- owner-quoted repair $3,500 (median of 11 quotes)
- filed 2008–2025
Owners describe the steering wheel sticking near the center position, needing extra force to break free, and then releasing abruptly so the car over-corrects or weaves within the lane. Many say it is fine when the car is cool and appears or worsens after the car sits in the sun or once the cabin is warm, sometimes stated as above 75 to 85 degrees. Some report the wheel going heavy to the point that power assistance seems to drop out. Complaints mention dealers sometimes replaced the steering column or steering box, and in other cases could not reproduce the condition or reported nothing wrong. Spread widely from very low mileage up to about 95,000 miles, most often described in warm weather or after the car is parked in the sun.
What to check: Drive the car for at least 20 to 30 minutes on a warm day at highway speed and feel for any notch or hitch as you pass through center. Ask whether the steering column or steering gear has ever been replaced and request any related repair paperwork.
2 excerpts from owner complaints in NHTSA records
“2005 Bmw Z4. After driving the vehicle for around 300+ miles the steering start to stick, making holding the car in your lane very difficult. We purchased the vehicle in oct. Or nov. Of 2010 and it had approx. 56000 miles on the odometer. I first noticed the problem in dec. When we went to fla. And last week when we traveled to s.c.”
NHTSA complaint #10384799, filed 2011-02, 59,800 miles“I experience sticking steering that progressively gets worse as I drive my vehicle. My steering tends to stick to the right and will not self align itself until I forceable center the wheel. The same problem occurs turning left but currently it is not as severe. The problem is present on city streets, highways and while turning.”
NHTSA complaint #10954604, filed 2017-02, 95,250 miles - Steering
Steering play and wandering at highway speed
- 14 complaints (7%)
- median 37,668 mi at 9.4 yrs old (12 state mileage)
- filed 2009–2021
Some owners describe a dead zone around center where wheel movement produces no change in direction, followed by an abrupt response once that play is taken up, so the car moves noticeably within its lane. Complaints link this to the same steering system and note that tire pressure, balance and alignment checks did not change it. One owner was told the steering column electric motor was at fault and that the entire column had to be replaced. Reported from as little as 500 to about 9,000 miles at the low end, up to roughly 60,000 miles, and again more noticeable in warm conditions.
What to check: On a straight, quiet road at moderate speed, check for free play at the top of the wheel before the car responds, and confirm alignment and tire pressures were recently checked.
2 excerpts from owner complaints in NHTSA records
“While driving on the straight highway at a normal speed I noticed the car began to pull to the right. In order to correct, you would have to pull the steering wheel to the left causing the car to sometimes over correct with a jerking sensation and pulling to far to the left. Car was taken in for repair. After diagnostics I was told that it was a problem with the steering column electric motor and you could not just replace the motor, but would have to have the entire steering column replaced. …”
NHTSA complaint #10585879, filed 2014-05, 57,328 miles“2005 Bmw e85 with only 9,000 miles. Driving in straight line, steering wheel has unusual amount of 'play' where no wheel direction change will occur. When exceeding the 'play' an amount of resistance is encountered followed by an abrupt wheel direction change. At 40 MPH car will suddenly move 1-2 feet in lane. Vehicle requires constant, jerking correction. This condition has existed since purchase of the vehicle 2 months ago but is much worse on hot days such as the current 85 degree weather. …”
NHTSA complaint #10410781, filed 2011-07, 9,000 miles
Buying note. The steering behavior is the main thing to evaluate on this model year, and because it depends on temperature a short drive in cool weather may not reveal it. Plan a longer warm-weather drive and ask for any steering-related service history before deciding.
Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample. The excerpts come from NHTSA's public complaint records and are unverified; capitalisation is normalised, NHTSA staff notes are removed, and shortened text ends with “…”. Something wrong?

Example complaints
Steering: “Stiff steering when the temperature rises. There is resistance turning left or right off center. Off ramps seem to be the most dangerous because once I turn right off center the vehicle wants to continue turning right. This has happened every time I've driven this vehicle when the temperature is above 85 degrees.”
NHTSA complaint #11120952, filed 2018-08, 140,000 milesAir bags: “On august 7, 2007 I took my car to sterling Bmw in newport beach, ca because I noticed the airbag malfunction lights were on along with other electrical issues. After they had inspected my vehicle for three days I was informed that the airbag/electrical problem would not be covered by the Bmw factory warranty, and the service department recommended that I file a claim with my insurance carrier. Obviously my insurance company denied the claim, because automobile insurance does not cover loss due to wear and tear, mechanical or electrical breakdown/failure. …”
NHTSA complaint #10240250, filed 2008-08, 24,994 milesElectrical system: “Bought the 2005 z-4 Bmw used from a dealer in high point nc. Drove it and enjoy driving until the warm weather. The steering sticks to a point of being dangerous. To compensate, I steer to the left and car pulls to the left then I bring the steering back towards the center and feel it sticking so I compensate by steering to the right. The whole time down the highway I fear for my life driving this car. I really had to concentrate to keep the car from steering off the road and I'm sure it appears I'm driving erratically to others on the road. …”
NHTSA complaint #10504547, filed 2013-03, 99,662 milesEngine: “The contact owns a 2005 Bmw Z4. The contact stated that when turning on the vehicle, there was an abnormal noise. The vehicle was taken to a dealer, who diagnosed that the belt tensioner needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure.
