What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2010 BMW Z4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
CAR IS A NEW (11 /21/09) BMW Z4 WITH LESS THAN 2,000 MILES. WHEN DRIVING IN SUBURBAN TRAFFIC AT APPROXIMATELY 45MPH, DRIVER SIGNALED FOR A RIGHT HAND TURN AT AN INTERSECTION WITHOUT A TRAFFIC LIGHT. WHEN BRAKES WERE APPLIED, THERE WAS VIRTUALLY NO STOPPING POWER. UNABLE TO SLOW FOR THE RIGHT TURN, DRIVER PROCEEDED TO THE NEXT TURN WHILE APPLYING ALL OF THE PHYSICAL PRESSURE SHE COULD MUSTER, WHICH FINALLY SLOWED THE CAR TOP THE POINT IT COULD BE TURNED AND STOPPED. IF THIS BRAKE FAILURE HAD OCCURRED WHEN THERE WAS STOPPED TRAFFIC, AN ACCIDENT WOULD HAVE CERTAINLY OCCURRED. THE PROBLEM WAS A CATASTROPHIC FAILURE OF THE POWER BRAKES HYDRAULIC BOOSTER. ADDITIONALLY, NO WARNING LIGHT EVER CAME ON BEFORE, DURING OR AFTER THE BRAKE FAILURE. THE BMW SERVICE DEPARTMENT SAID THAT THERE ARE WARNING LIGHTS FOR LOW FLUID AND LOW PADS, BUT NOT FOR BOOSTER FAILURE, WHICH IS UNBELIEVABLE. *TR

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
DURING A COLD, DRIVING RAIN STORM, WITH DRIVER & 1 PASSENGER, STARTED TO DRIVE. (VERY 1ST DRIVE IN THIS CAR WITH COLD WEATHER) WHAT A SURPRISE: WINDSHIELD IMMEDIATELY FOGGED UP. TURNED ON DEFOGGER, WINDSHIELD THEN FOGGED UP 100% AS WELL AS ALL OTHER WINDOWS - AS VISIBILITY DISAPPEARED, I STOPPED THE CAR & OPENED THE WINDOWS WITH THE BLOWER ON. NO HEAT COULD BE USED. THIS PROCESS WAS REPEATED OVER THE NEXT 1 TO 1-1/2 HOURS IN ORDER TO CONTINUE DRIVING. ISSUE WAS REPORTED TO BMW MANY TIMES OVER. I HAD TO LEARN THAT DESPITE COLD AMBIENT TEMPERATURES W-W/O RAIN, SNOW, ETC. - THE A/C MUST BE TURNED ON IN ORDER TO NOT FOG THE WINDOWS. BMW: THERE'S NOTHING TO FIX, THAT'S THE WAY IT IS. THE AMBIENT AIR IS DIRECTED THROUGH A PORTION OF THE ENGINE COMPARTMENT, THIS HEATS UP THE AIR. BMW STATED THAT I MAY VOID THE WARRANTY IF I MODIFY THE SYSTEM TO CORRECT THIS PROBLEM. THIS HAS CONTINUED TO OCCUR. ON A DRIVE ON CA'S COAST HIGHWAY, WITH TEMPS IN THE LOW 50'S - ONE MUST STILL RUN THE A/C & NO HEAT. BMW ASKED: WHAT DO YOU HAVE AGAINST RUNNING THE A/C ALL THE TIME? IN ADDITION TO IMPAIRED VISIBILITY - THIS RESULTS IN CONSTANT, VERY LOW MPG WITH THE A/C ALWAYS ON. WHEN BMW PROVIDED MPG'S TO FED. AGENCIES, I BELIEVE THAT BMW'S A/C'S WERE NOT ON & THESE CARS DEMAND PREMIUM FUEL. I SPOKE WITH A NATIONALLY KNOWN, RESPECTED TESTER/ADVISERS OF MANY VEHICLES - IT WAS CONFIRMED TO ME THAT THE MPG TESTS ARE CONDUCTED WITHOUT THE A/C'S BEING TURNED ON. *TR

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
BMW HAS ACKNOWLEDGED A KNOWN ISSUE CAUSING FAILURE OF THE HIGH PRESSURE FUEL PUMP. THE BMW TECHNICAL BULLETIN IS (SI B 13 03 09). THIS EXTENDS THE WARRANTY OF THE PART TO 10 YEARS. THE PROBLEM IS THAT THE FAILURE IS NOT WELL DOCUMENTED BY THE VEHICLE ISSUE LOGGING SYSTEM, AND THAT OTHER ISSUES WITH THE CAR ARE CITED AS A REASON TO NOT PERFORM THE PART REPLACEMENT. BMW N. AMERICA AND BMW OF AUSTIN DO NOT, AND CAN NOT PROVIDE A TEST TO CHECK THE VEHICLE'S FUEL SYSTEM INDEPENDENTLY. THIS PUTS DRIVERS, PASSENGERS AND ANYONE ELSE AT RISK SHOULD THE PART FAIL SUDDENLY AFTER EXHIBITING PARTIAL FAILURES. THE COMPLAINT SHOULD ALSO NOTE THAT BMW DOES NOT PROVIDE AN EASY WAY TO REPORT THIS IMPORTANT SAFETY ISSUE AS THERE IS NO FIXED PROCESS TO DOCUMENT THE ISSUES.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
