New Car Assessment Program

The 2003BMWZ4 carries 459 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 7 crashes, 0 fires, 2 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2003 Z4 is steering with 325 filings, followed by air bags (27) and electrical system (13). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 4 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 34 investigation files overlapping the 2003 Z4. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Steering is binding up, very hard to steer and control. Car starts out running fine after parked in hot weather and restarted it is almost uncontrollable. Looking for corrective action.

When outside temp is 80degrees or higher it becomes difficult to maintain the vehicle in the correct driving lane due to a stickyness in the steering wheel. I will not allow anyone to drive the vehicle when the temp is over 80 degrees ... sucks to have a convertable that you can't drive in warm weather!

My girlfriend, [XXX] , purchased a used 2003 BMW z4 2.5i. It is pristine with 47K original miles. Always maintained, garaged and never driven in foul weather. I, [XXX] , drove it home for her and noticed the steering to be "sticky". This showed on the highway traveling at 65 MPH. It was very unsettling to feel the car want to track in a direction that i could not control. I used "more force" to pull the steering wheel to get tracking correctly and stay in my travel lane. Lucking I did not overcorrect and lose control or cause and accident. Once it happened it continued to happen the balance of the drive on the highway and back roads. I've owned and driven many different makes and models of vehicles from Dodge, Renault, Toyota, GMC, Chrysler, Volvo, Geo, etc. and never has "steering" been an issue. Once we got home I looked up "sticky steering" issue for the 2003 Z4 and this is a known issue. Driving this BMW was unsettling and unsafe. INFORMATION REDACTED PURSUANT TO THE FREEDOM

Upon starting the car, power steering does not work making car unmanueverable.

20230418STEERING

The steering in this BMW Z4 gets "sticky" in warm or hot weather. It drives fine in cold weather. The steering has to be constantly corrected as it pulls to the left. It will not track in a straight line and needs constant corrections from side to side to compensate for the problem. If you do not pay close attention and correct the steering input, you will go off the road. On a warmer day after driving for a while I suddenly experienced a unexpected binding of the steering and almost ended up steering into oncoming traffic. This car is not safe to drive. The 2003 model has electric power steering. There are no codes or warning lights. I took the car to the local mechanic and he was easily able to reproduce the issue when he drove it less than 1 mile. This issue not only puts me at risk but others because of the constant correction of the steering to keep a straight. If you drive this car in warm or hot weather distances more than 20 miles then shut if off, then attempt to restart ther

STICKY STEERING AFTER CAR WARMS UP. STEERS LIKE A BOAT. DANGEROUS AT HIGHWAY SPEEDS OR WINDING ROAD.

The contact owns a 2003 BMW Z4. The contact stated while driving at various speeds in hot weather, the steering wheel became difficult to turn and would also jerk the vehicle into the next lane. The contact stated no warning light was illuminated. The contact was able to drive to the residence. The contact took the vehicle to the local dealer, where it was diagnosed with needing the battery to be replaced. The dealer replaced the battery however, the failure recurred. The manufacturer had been informed of the failure. The failure mileage was approximately 24,000.

During very warm days in the summer the steering wheel tends to stick during turns. It requires extra force to continue to turn the wheel which becomes problematic during a tight turn or on highway on-ramps.

Car has 15,000 miles and always stored in climate controlled garage. Drove it today and within 1/2 mile the electronic power steering failed making it very, very hard to steer. Shut vehicle off and restart and the problem goes away but only for a minute or two and then returns.

I purchased this BMW Z4 from a private seller on Thursday (3/10/22) located in Myrtle Beach, SC. On the way home (187 mile trip), about ¾ of the trip, I was driving about 55 mph on 701 North and the steering felt as if it was sticking to the point where moving the wheel took a effort to unstick it which put me into oncoming traffic in the other lane. I almost was involved in a head-on collision! The vehicle has only 39K miles on it. The previous owner had this issue in April of 2008 and took it to a BMW dealer who advised them that the repair would cost $2,950.00. The previous owner declined the repair because they couldn’t afford it and the dealer told them that BMW will probably issue a recall AS HUNDRES OF Z4 OWNERS HAVE HAD THIS SAME ISSUE. The vehicle also drifts to the left and attempts by the previous owner to have the vehicle aligned to correct this have failed. The vehicle had only 13K on the odometer at the time BMW advised of the faulty steering column.

On hot days the steering becomes sticky like there is a catch. It will also pull to one side or the other making it very dangerous to drive especially on the interstate.

I JUST PURCHASED Z4. DID NOT NOTICE ANY PROBLEM DURING TEST RIDE. ON MY WAY HOME DURING PURCHASE STEERING BECAME AN ISSUE. THE CAR WOULD BE DRIVING FINE THEN WHAT I WOULD A DEAD SPOT WOULD APPEAR. THE STEERING WHEEL WILL SUDDENLY SHIFT LEFT OR RIGHT WHAT SEEMS A FEW INCHES. THIS CAUSES DRIVER (ME) TO COMPENSATE TO AVOID GOING IN DITCH OR CROSSING A LANE OR GETTING INTO AN ACCIDENT. THIS HAPPENED MANY TIMES ON MY 70-MILE TRIP HOME.

THE FIRST ISSUE IS THAT THE POWER STEERING WILL GO OUT DURING NORMAL OPERATION OF THE VEHICLE MAKING THE WHEEL HARD TO TURN. ADDITIONALLY, AT RIGHT ABOUT THE STRAIGHT POSITION OF THE STEERING WHEEL THE STEERING WILL STICK (CONSISTENTLY FIGHTING THE WHEEL TO STAY CENTERED). STAYING STRAIGHT IS NEARLY IMPOSSIBLE AS YOU CONSTANTLY BATTLE THE RESISTANCE BACK AND FORTH TO KEEP THE VEHICLE MOVING IN A STRAIGHT LINE. IT IS QUITE DISCONCERTING AND HAS ALMOST RESULTED IN ME SIDE SWIPING ONCOMING VEHICLES ON SEVERAL OCCASIONS. I HAVE LEARNED THAT THIS IS A COMMON PROBLEM THAT BMW NEVER ADDRESSED. RESEARCHING THE MATTER I'VE LEARNED THAT A STEERING COLUMN REPLACEMENT AND LABOR WOULD BE IN THE $3000-4500 RANGE AND THE PROBLEM WOULD LIKELY REOCCUR IN THE FUTURE DUE TO FAULTY DESIGN. WORSE, AS MOST PEOPLE IN MY POSITION ARE UNABLE TO PERFORM A REPAIR AT THAT COST, I'VE FOUND NUMEROUS PEOPLE MANIPULATING THEIR STEERING COLUMNS WITH MIXED SUCCESS ULTIMATELY CREATING AN EVEN MORE DANGEROUS POTENTIA
