NHTSA Complaint #10633047 — 2008 BMW 335I

THE ENGINE IS IDLING VERY ROUGHLY AT A FULL STOP WHETHER ITS A TRAFFIC LIGHT, OR JUST STOP AND GO TRAFFIC. THE RPMS WILL SPIKE TO 750-800 RPMS AND DROP BELOW 5-400 RPMS RANDOMLY CAUSING THE ENTIRE CAR TO SHAKE VIOLENTLY, AND STALL AT TIMES.THE INCIDENT SEEMS COMMON WITH MY MODEL CAR THOUGH ONLINE FORUMS AND FRIENDS THAT HAVE THE SAME CAR AND THE 328 WITH N54 ENGINE. MY MAIN ISSUE IS THAT THERE IS NO MALFUNCTION CODE ASSOCIATED WITH IT, AND IT HAPPENS RANDOMLY; SOMETIMES WHEN THE CAR IS COLD, SOMETIMES AT RUNNING TEMP, SOMETIME WITH AC ON, SOMETIMES WITH AC OFF. THERE DOESN'T SEEM TO BE A SPECIFIC VARIABLE CAUSING THE ISSUE, BUT IT IS A MAJOR ISSUE NON THE LESS, THEREFORE BMW DEALERSHIP CAN'T SEEM TO FIGURE OUT A FIX FOR MY PROBLEM AND CONTINUOUSLY TURN ME AWAY EVEN THOUGH I HAVE EXTENDED BUMPER TO BUMPER WARRANTY. THIS ISSUE HAS BECOME A SAFETY CONCERN OF MINE AND I DON'T WANT IT TO GET WORSE AND CAUSING AN SUDDEN LOSS OF POWER OR AN ACCIDENT. I'VE NOTICED THAT THERE WAS A RECALL FOR 2007-2011 3-SERIES FOR LOSS OF ELECTRICAL POWER/STALLING, BUT I'M NOT SURE IF ITS THE SAME CIRCUMSTANCE FOR MY CAR OR DIFFERENT. *TR
