What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 BMW 750I, 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.

Each component in detail
What the reports in each category say, in the owners' own words

Powertrain (other)

From owner reports, verbatim
Transmission secure vehicle with parking break when stationary. The vehicle jumps from park to neural by its self randomly and pops up with the transmission warning. Heard it's a common problem should be recalled
THERE IS WHITE SMOKE THAT IS COMING OUT OF THE BACK PIPES OF THE CAR. THE CAR IS BURNING THROUGH OIL. I AM PUTTING A QUART IN EVERY 2 -3 WEEKS. MY MECHANIC SAID THAT IT IS HAVING THE SAME PROBLEMS AS THE 2009 MODEL. THE 2009 750I HAS BEEN RECALLED TO FIX THE ENGINE PROBLEM AND I HAVE A 2012 MODEL. THE SMOKE COMES OUT WHEN I AM DRIVING NOT WHEN IT IS STATIONARY ON THE CITY STREET, HIGHWAY OR WHEREVER. I DON'T FEEL SAFE. I AM GOING TO START DRIVING MORE DISTANCE AND I DON'T WANT TO RUN OUT OF OIL AND CAUSE MORE DAMAGE TO MY CAR. I DON'T UNDERSTAND WHAT IS HAPPENING WITH THE OIL CONSUMPTION. THERE ARE OTHER ISSUES SURROUNDING THE CAR. I AM NOT A MECHANIC. BUT, I WOULD LIKE TO FILE A COMPLAINT. THIS CAR WAS SUPPOSED TO BE IN EXCELLENT CONDITION WHEN I BOUGHT IT.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
DEALER REPORTED THAT MOISTURE ENTERED A WATERPROOF ENCLOSURE THAT HOUSES THE BRAKE MODULATOR. WATER ENTERED THRU A DRAIN HOLE FROM THE COWL AND BYPASSED A PLATE MEANT TO KEEP WATER OUT. ONCE EFFECTED BY MOISTURE THE MODULATOR SHUT DOWN ALL FUNCTIONS OF THE CAR INCLUDING THE ENGINE WHILE MOVING. BMW BLAMED IT ON PARTIAL SUBMERSION OF THE MODULATOR BUT CAR WAS NEVER EFFECTED BY WATER/SUBMERSION AND THE DEALER AGREED THAT THEIR WAS NO EVIDENCE OF THAT AND COULD NOT FIND ANYTHING TO SUPPORT THAT CONDITION. UPON REPAIR DEALER WENT TO GREAT LENGTHS TO TRY AND SEAL COMPARTMENT AND INSTALL DIVERTER THAT WAS REPLACED IN THE REPAIR TO PREVENT REOCCURRENCE. THIS IS A VERY DANGEROUS CONDITION THAT APPEARS TO BE A MANUFACTURING DEFECT IN MANUFACTURE ON A VERY LIMITED NUMBER OF CARS MADE BY BMW FOR THIS SPECIFIC MODEL. OWNERS NEED TO KNOW THAT THE CONDITIONS EXPERIENCED HAVE A MUCH DIFFERENT EFFECT ON SAFETY DUE TO THE HYBRID DESIGN THAN A STANDARD NON HYBRID CAR.

From owner reports, verbatim
The contact owns a 2012 BMW 750I. The contact stated that while stopped in traffic, a wildfire began to approach his vehicle. The contact then stated that white smoke obstructed his vision on the highway. As the contact depressed the accelerator pedal, the vehicle stalled with the transmission disengaged message on the instrument panel. The contact restarted the vehicle three times before the transmission re-engaged and the contact was able to escape the thick smoke that had covered his vehicle. The contact called the dealer and spoke to a service advisor who stated that the heat from the fire caused the vehicle to stall. The manufacturer was also notified of the failure and referred him back to the dealer for an inspection. The vehicle was not repaired. The failure mileage was approximately 56,000.
