NHTSA Complaint #10440322 — 2009 BMW 335XI

VEHICLE OIL TEMP WAS JUST UNDER 250. VEHICLE SHAKES WHEN ACCELERATING ON THE HIGHWAY OR ON AN INCLINE. ENGINE LIGHT COMES ON AND YOU CAN FEEL THE VEHICLE MISFIRING IN THE GAS PEDDLE. VEHICLE CONTINUES TO SHAKE IN PARK. DEALER ADVISED TO TURN THE VEHICLE OFF AND LET IT SIT FOR 30 MIN BEFORE DRIVING AGAIN. SEEMS TO BE A TEMPORARY FIX UNTIL THE ENGINE TEMP INCREASES TO JUST UNDER 250 OR DRIVING ON A INCLINE ON THE HWY. PREVIOUSLY HAD NO ISSUES WITH THIS VEHICLE UNTIL DEALER REPLACED A HFP (RECALL NOTICE) DURING AN OIL CHANGE. THIS WILL BE THE THIRD COMPLAINT ABOUT THIS ISSUE SINCE 11/23/11 THAT THE DEALER HAS NOT BEEN ABLE TO FIX. PREVIOUSLY BEEN TOLD INJECTORS WERE MALFUNCTIONING DUE TO PROGRAMMING AND ALSO BAD GAS. I HAVE ALWAYS USED PREMIUM 91+ OCT GAS. RECENTLY THE DEALER PUT IN A FUEL ADDITIVE AND ADVISED ME TO USE SHELL OR CHEVRON PREMIUM GAS IN THE FUTURE. I DROVE OUT THE FUEL ADDITIVE TANK, NO ISSUES AND REFUELED AT SHELL USING PREMIUM 91 POWER V. FORTY FIVE MINUTES LATER, MY VEHICLE BEGAN TO SHAKE ON THE HWY ONCE AGAIN AND MY CHECK ENGINE LIGHT CAME ON. I WAS FORCED TO SUDDENLY SLOW DOWN ON THE HIGHWAY TO A SPEED / GEAR WHERE I WOULDN'T SHAKE. PREVIOUS DRIVING HISTORY IN EU WITH NO ISSUES ON THE AUTOBAHN AND THE VEHICLE IS A US SPEC. ONCE THE VEHICLE WAS SHIPPED TO CA, I DROVE IT TO AZ (800 MILES) WITH NO ISSUES AND CONTINUED TO DRIVE THE CAR UNTIL SEPT WHEN I HAD MY OIL CHANGED AND MY HFP REPLACED. MY FIRST LONG HWY DRIVE SINCE THE OIL CHANGE / HFP WAS REPLACED, WE ENCOUNTERED THIS ISSUE. *TR
