Bmw 750LI problems and owner complaints

I HAVE A BMW 750LI SEDAN. THE TRANSMISSION IN THIS CAR INTERMITTENTLY BUT APPROXIMATELY 1 TIME PER MONTH HAS A VIOLENT DOWNSHIFT INTO A LOW GEAR. IT FEELS LIKE YOU HAVE JUST BEEN REAR ENDED BY ANOTHER CAR AND IT IS POSSIBLE TO GET A NECK INJURY FROM THIS "VIOLENT" SLAMMING. IT HAPPENS TO OTHER OWNERS OF THIS CAR AS I HAVE READ ABOUT IT ON MANY FORUMS. BMW WON'T DO ANYTHING ABOUT IT IF YOU CAN NOT REPLICATE THE PROBLEM. IT SEEMS TO HAPPEN MOST OFTEN WHEN YOU ARE TRAVELING AT SLOW SPEEDS GOING UP A STEEP HILL AND YOU TAKE YOU FOOT OFF THE AC…

2006 BMW 750LI. CONSUMER STATES COMPLETE LOSS OF BRAKING SYSTEM. *TGW THE CONSUMER WAS ABLE TO USE THE MANUAL TRANSMISSION TO DOWNSHIFT TO FIRST GEAR. AT THE TIME OF THE BRAKE FAILURE, THERE WAS NO WARNING ON THE ELECTRONIC DASHBOARD TO SUGGEST ANY MALFUNCTION OF THE ENGINE, BRAKE FLUID, FRONT BRAKES ETC. ACCORDING TO THE SERVICE INVOICE, THE VACUUM PUMP LEAKED OIL INTO THE VACUUM SUPPLY HOSE TO THE BRAKE BOOSTER WHICH CAUSED THE BOOSTER TO FAIL. *JB

TL*THE CONTACT OWNS A BMW 750 LI. HE LIVES ON A NEAR A CLIFF AND WHEN HE PARKS HIS VEHICLE ON AN INCLINE THE VEHICLE LURCHES FORWARD. THIS HAPPENS CONSISTENTLY 20 SECONDS AFTER PARKING THE VEHICLE AND ENGAGING THE EMERGENCY BRAKE. HE FIRST NOTICED THE FAILURE, APPROXIMATELY IN FEBRUARY 2007, AFTER PARKING ON AN INCLINE. THE DEGREE OF THE INCLINE IS NOT RELEVANT TO THE FAILURE, EVEN A SLIGHT INCLINE WILL PRODUCE THE FAILURE, BUT A LARGE INCLINE WILL JOLT THE VEHICLE FORWARD MORE VIOLENTLY. THE WEATHER WAS NOT A FACTOR IN THE FAILURE. HE W…

ON 1-25-2010 I WAS GOING TO NEW PORT BEACH AND TRAVELING ON FWY405N. ABOUT 5 MINUTES BEFORE THE PLACE OF ACCIDENT MY CAR STARTED SWIRLING ABOUT 2' LEFT AND RIGHT AND I WAS VERY WORRIED.

WHEN PUSHING ON THE GAS, THE VEHICLE WOULD STALL, RPM'S WOULD SHOOT UP, AND WOULD TAKE 3-10 SECONDS TO RE-GAIN ANY POWER BEFORE THE VEHICLE WOULD BEGIN TO ACCELRATE. ALSO ONCE COMING UP TO A STOPLIGHT OR STOP SIGN, THE VEHICLE WOULD FEEL AS IF SOMEONE HAD SLAMMED INTO THE BACK OF ME POSSIBLY JERKING INTO GEAR. SPENT COUNTLESS TIMES AT THE DEALERSHIP WITH THEM GIVING ME THE RUN AROUND, REPLACING RANDOM PARTS BEFORE REPLACING THE ENTIRE TRANSMISSION AND STILL THE VEHICLE CONTINUES TO HAVE ISSUES. *TR
