32 totalThese are consumer-submitted safety complaints filed directly with NHTSA. Each complaint describes a real owner's experience. Complaints flagged as crash-related or fire-related are highlighted.
The contact owns a 2022 BMW Z4. The contact received notification of NHTSA Campaign Number: 23V099000 (Visibility, Electrical System) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and advised the contact to locate parts near to his residence. The contact had not experienced a failure. VIN tool confirms parts not available.
There is a strong chemical smell when the AC is turned on and the system is loosing refrigerant. There is a common issue on these cars of premature evaporative core corrosion.
The contact owns a 2016 BMW Z4. The contact received notification of NHTSA Campaign Number: 24V608000 (Engine and Engine Cooling, Electrical System); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.
The air conditioning system has a very very foul musty smell when you first start the vehicle after sitting for a few hours. It will go away after a few minutes, but the dealer nor repair shops can fix the issue. System was cleaned, new micro air filter was installed, but still have the musty odor. Even the a/c drain was cleaned, all to no avail. This seems to be a class thing with all BMW vehicles according to the many BMW owners I have spoken with. But no one can fix the problem.
TL* THE CONTACT OWNS A 2016 BMW Z4. THE CONTACT STATED THAT WHILE HIS WIFE WAS STOPPED AND THE BRAKE PEDAL WAS DEPRESSED AN UNKNOWN NOISE WAS HEARD AS, THE VEHICLE ACCELERATED OUT OF CONTROL AND CRASHED INTO THE REAR OF THE VEHICLE IN FRONT CAUSING THAT VEHICLE TO CRASHED INTO THE VEHICLE AHEAD OF IT. THERE WERE NO WARNING LIGHTS ILLUMINATED. THE DRIVER'S SIDE FRONTAL AND KNEE AIR BAGS DEPLOYED. THE DRIVER SUSTAINED MINOR INJURY THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN AUTO BODY REPAIR FACILITY. THE CONTACT CALLED THE BMW OF TEMPLE DEALER (6006 S GENERAL BRUCE DR, TEMPLE, TX 76502) AND WAS TOLD TO CALL THE MANUFACTURER. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AS THE CONTACT WAS AWAITING THE REPORT FROM THE EVENT DATA RECORDER (EDR) AND A CASE WAS OPENED. THE CONTACT WAS CONCERNED AS HE WANTED THE CAUSE OF THE FAILURE TO BE DIAGNOSED BEFORE THE VEHICLE WAS RETURNED TO HM. THE FAILURE MILEAGE WAS APPROXIMATELY 8,000. THE VIN WAS NOT AVAILABLE.
ABOUT 20% OF TIME, DRIVER SIDE SEAT BELT JAMS, WILL NOT RELEASE FROM RECESS/RETAINER BEHIND SEAT WITHOUT USING MY HAND FOR COUPLE MINUTES TO JIGGLE ENOUGH. NO PROBLEM ONCE I GET IT TO RELEASE. THEN FITS IN CONNECTOR AND ALSO RELEASES OK. TWO LOCAL DEALERS UNABLE TO FIX. ONE EVEN REPLACED ENTIRE MECHANISM, STILL JAMS. MANAGER SAID THIS MODEL SEEMS TO HAVE THIS PROBLEM. THIS OCCURS AT A STAND STILL, BEFORE PUTTING CAR IN GEAR, SOMETIMES WITH MOTOR ON, SOMETIME BEFORE I START THE ENGINE. SOMETIMES JUST OPENING THE DOOR CAUSES THE RELEASE. OTHER TIMES, I HAVE TO PUT MY HAND UNDER THE BELT AND MANEUVER THE BELT UNTIL IT RELATES FROM THE RETAINER INTO WHICH THE BELT RETRACTS. NO PICTURES INCLUDED. JUST A STANDARD SEAT BELT. HAD A BMW 3351 FOR 7 YEARS. NEVER HAD THIS PROBLEM ONCE.

The contact owns a 2019 BMW Z4. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted. The manufacturer was not made aware of the issue. The contact had not experienced a failure.
Reporting premature part fail. -The 2019 BMW has 14,300 miles. The vehicle recently failed VT state inspection for "Play in control arm ball joints" Normal ball joint replacement is usually in the 60,000 mile range. The 1st recommended check of steering components per BMW service manual is is "6th engine oil service (approx 60,000 miles)". There was no warning of the premature fail. The failed parts will be replaced and used parts preserved for inspection if needed.
My grill shutters are faulty and the problem has been persistent and the vehicle is only at 30,000 miles. This is the same part that was issued an extended service contract by BMW for various other models. I believe my model is rare enough to not be included but it should. The existing recall/warranty is βSIB 01 12 19 FRONT GRILLE UPPER/LOWER ACTIVE AIR FLAPS: LTD WTY EXT TO 15 YEARS/150,000 MILESβ and I believe mine should be included in this as it is the same engine as these various models. The grill shutters are experiencing the same fault and they do not open and close properly as the models listed. I receive code P05AF which is signals the lower shutters are not closing.
The automatic emergency did not engage the brakes as described to by the dealer, BMW genius and the BMW website. The car was in a collision at low speed (under 35mph) with the car in front of me which put me at risk. BMW sent an engineer from N.J. to inspect the car. The is under warranty and it was in perfect working order. The engineer determined that the system did not engage because the accelerator was depressed, I was told that the system does not work when the accelerator is depressed but that is not how the system is advertised and it is not how it was described in ALL of the BMW marketing materials.
MY NEW CAR CHECK ENGINE LIGHT GOES ON AND I HAVE BOUGHT IT INTO SERVICE APPOX 5 TIMES. THE LIGHT GOES OFF AND WHEN I GET IT HOME IT GOES ON AGAIN WHEN I START THE CAR. I THOUGHT IT WAS FIXED. HOWEVER IT CAME ON AGAIN AND I AM AFRAID TO DRIVE IT.
The engine starter failed on my 2020 BMW Z4 M40i. The vehicle experienced starting failures and the repair shop diagnosed a faulty/shorted engine starter assembly. The symptoms and component failure match the exact defect description of active safety recalls NHTSA 24V-576 and 25V-636 (Starter Motor Fire Risk due to electrical short circuit/overheating). However, when checking my specific 17-digit VIN, the manufacturer has excluded my vehicle from the recall population. Because this is an identical component failure that poses a severe vehicle fire and safety hazard, I am requesting that the NHTSA investigate a recall expansion to include my vehicle's production batch. I have retained the diagnostic reports and repair invoices as evidence.
Engine starter safety recall came out in September 2025, with no remedy or parts existing for fixing it. 5 months later, and no timeframe is provided for a remedy. This is a major fire risk given the amount of rain now that could corrode the starter and lead to a fire.
DON'T KNOW WHAT IS CAUSING IT. THERE IS MAJOR SQUEAKING/WHINING/GRINDING NOISE IF EVEN A TINY BIT OF WATER GETS IN THERE AND LAST COUPLE DAYS AFTER THAT. AND WHEN YOU TURN THE STEERING WHEEL TO THE LEFT THE SQUEAKING/WHINING GETS LOUDER. AND WHEN DOES DO THIS THE SUSPENSION IF YOU HIT EVEN A SMALL BUMP WILL BOTTOM OUT AND MAKE GRINDING NOISES. BMW HAS LOOKED AT THE CAR COUPLE TIMES FIRST TIME THEY SAID THERE WAS RUST. SECOND TIME THEY COULDN'T FIND ANYTHING WRONG WITH IT.
WAS IN A DRIVE THRU ON 9/6/2020 WAITING OUR TURN. APPROX. 7 CARS IN FRONT OF US. AS WE ARE SLOWLY MOVING UP TO ORDER, CAR IN IDLE, FOOT ON BRAKE. AS WE ARE MOVING FORWARD, WHEN WE WERE UP TO 3 CARS, STILL IDLING AND FOOT ON BRAKE, THE CAR HAD FULLY ACCELERATED, BRAKE NOT HOLDING THE CAR, INCHING FORWARD DUE TO THE FORCE OF THE ACCELERATION. TRIED TO SHIFT INTO NEUTRAL, WENT INTO REVERSE. TRIED AGAIN TO SHIFT INTO NEUTRAL, WENT INTO DRIVE, STILL INCHING FORWARD, AT THIS TIME I PUSHED THE OFF BUTTON TO STOP THE CAR. RESULT OF COLLISION WITH THE VEHICLE IN FRONT OF US. WE HAVE PHOTOS BUT NOT ON THIS COMPUTER.
BMW'S LANE DEPARTURE SYSTEM ACTUALLY PULLS THE CAR'S STEERING LEFT OR RIGHT, AND COULD CAUSE THE CAR TO COLLIDE WITH ANOTHER VEHICLE OR RUN OFF THE ROAD. I EXPERIENCED THIS WHILE DRIVING ON THE FREEWAY IN SOUTHERN CALIFORNIA. THE LANE DEPARTURE SYSTEM ALMOST PULLED MY VEHICLE INTO THE ADJACENT LANE.
Car hesitate/stutters when cold and you try to accelerate from a standstill with partial throttle. No engine codes are set. BMW could not duplicate issue.
My 2015 BMW Z4 vehicle has a coolant pump safety recall. It reportedly could cause a short circuit and thermal event or fire. I bought the vehicle while living elsewhere and am now in a small community with 4 major automobile dealers but not BMW. The nearest BMW dealer is about 220 miles away. I contacted that dealer. The service rep said it is 1.5-2 day repair and a loaner vehicle may be available. The repair time sounds wrong but is what she said. She said the dealership would not work with any facility close to me to make the repair so I must drive the 440 plus round trip miles for BMW dealer repair. Repair of 1.5 to 2 days means I would either need lodging and waste least 2-3 days of my time or drive back home with a 2nd trip to the dealer to return a loaner and get my car, 880 miles and many hours driving. Even a 1 day repair means 440 miles and many hours. Called BMW Recall Hotline at [XXX] & explained my situation. They declined help saying the dealer decides how the repair is handled. I called BMW Customer Service [XXX] . They declined help & said a BMW dealer must repair unless it wants to work with another repair facility. I submitted a web-form message on BMW's corporate website online message portal outlining the problem and requesting help to get the safety recall fix completed in a convenient manner; asked to escalate if possible. They replied 3 days later declining to help saying: "The recall would have to be performed at a BMW dealership. Unfortunately, towing assistance is not available for this recall. If you would like to have the repair performed at another mechanic, It would be a non-reimbursable out of pocket expense. I would not be able to submit an escalation in this matter because it does not meet the criteria to be escalated. I apologize about an inconvenience this may cause." This seems unreasonable for a safety recall that could cause a car fire. Can NHTSA please help me obtain a reasonably convenient repair from BMW?

The basics
How to read this data
Complaints, recalls, investigations β hereβs what each number actually tells you about a used BMW Z4, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is β but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The BMW Z4 has 32 complaints on record across 10 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The BMW Z4 has 29 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 3 of the BMW Z4's 32 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions β a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Average) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable β simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all BMW Z4 vehicles on the road β not any specific car. Two BMW Z4 vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage β NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The BMW Z4 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
