NHTSA Complaint #10356054 — 2009 BMW Z4

I AM LEASING A 2009 Z4 BMW, THE ENGINE CAR STALL WHILE DRIVING THIS HAPPENED TWICE IN A PERIOD OF 2 WEEKS, I ALMOST HAVE A CAR CRASH BEHIND IN BOTH OPPORTUNITIES, THANKS THAT THE TRAFFIC WAS VERY SLOW, THE SECOND TIME I HAVE TO GO OUT THE ROAD. I BROUGHT THE CAR THE FOR SERVICE, THEY WERE ABLE TO REPRODUCE THE FAILURE, AFTER ONE WEEK AT THE SHOP THEY SAY IT WAS A COMPUTER FAILURE, THEY REPLACE THE COMPUTER HOWEVER AFTER 2 WEEKS THE CAR STILL IN THE SHOP I HAVE CALL SEVERAL TIMES TO CUSTOMER SERVICE AND THE SERVICE SHOP BUT I DON'T GET ANY SPECIFIC ANSWER OF WHAT IS GOING ON, I FEEL I DON'T HAVE ANY RIGHTS AS A CONSUMER AND IN THE OTHER HAND I AM CONCERNED FOR MY SAFETY SINCE THEY SAID THEY DON'T GUARANTEE THIS WON'T HAVEN AGAIN EVEN IF THE CAR IS FIXED. DO I HAVE ANY RIGHTS AS A CONSUMER OR I HAVE TO ACCEPT THIS SITUATION. *TR
