NHTSA Complaint #10765042 — 2005 BMW 545I

I STARTED HAVING PROBLEMS SEVERAL MONTHS AGO THAT HAS PROGRESSIVELY GOTTEN WORSE. WHEN I ACCELERATE FROM A STOP, IT APPEARS THAT THE AUTOMATIC TRANSMISSION IS STRUGGLING TO GET TO THE NEXT GEAR. THE RPMS WILL FLUCTUATE UP AND DOWN AND SOMETIMES REV WAY UP BEFORE THE CAR KICKS LIKE I HAVE BEEN HIT. IF I TRY TO ACCELERATE FAST FROM A STOP, THE ENGINE WILL REV UP TO ABOUT 5K RPM AND STOP RESPONDING UNTIL I LET OFF THE GAS AND LET THE RPMS DROP DOWN AND THEN IT WILL KICK INTO GEAR. IF I SLOW DOWN TO ALMOST A STOP AND THEN ACCELERATE IT WILL MOST CERTAINLY KICK, SO I HAVE TO BE VERY CAUTIOUS. I HAVE TO MAKE SURE I HAVE PLENTY OF ROOM WHEN PULLING OUT OF AN INTERSECTION BECAUSE I NEVER KNOW WHEN IT WILL ACT UP (WHICH IS MOST OF THE TIME) AND HINDER MY ACCELERATION. ONCE I GET UP TO CRUISING SPEED (ABOVE 45 MPH) IT RUNS SMOOTHLY, BUT IT HAS GOTTEN TO THE POINT THAT I DREAD EVERY TIME I HAVE TO STOP AT AN INTERSECTION OR SLOW WAY DOWN. I TALKED TO THE DEALER AND SAID IF IT WAS THE TRANSMISSION THEN THE SERVICE LIGHT WOULD COME ON. HE ASKED ME WHAT KIND OF GAS I USE AND I SAID SHELL HIGH OCTANE AND HE SAID THAT IS GOOD. OTHER THAN THAT, HE DIDN'T TELL ME MUCH MORE. I WANT TO SELL THE CAR NEXT SPRING BUT WHO WILL BUY IT WITH IT PERFORMING THIS WAY?
