2011 BMW Z4

THE CAR STALLED FOR THE FIRST TIME. I WAS DRIVING FOR ABOUT 5 MINUTES AT AROUND 25-35 MPH AND MADE A STOP AT A TRAFFIC LIGHT. WHILE AT A COMPLETE STOP, THE CAR ENGINE AND ALL THE ELECTRICAL SHUT OFF COMPLETELY WHILE IN GEAR. I PUT THE CAR INTO 'PARK' THEN TRIED TO RESTART. IT DID NOT START THE ENGINE BUT THE ELECTRICAL CAME BACK ON AND THE YELLOW CHECK ENGINE LIGHT APPEARED. AFTER TWO ATTEMPTS (TAKING KEY OUT, PUTTING KEY IN, AND STARTING THE ENGINE), THE CAR STARTS AGAIN AND EVERYTHING WENT BACK TO NORMAL. *TR

ON 01/05/2012, BMW SERVICE CENTER REPLACED AN IDRIVE PART AND REPROGRAMMED THE CAR. WHEN I PICKED UP THE CAR, I NOTICED AC IS NOT WORKING. SERVICE CENTER TOOK IT BACK AND DID A MASTER RESET. AFTER THAT SEVERAL TIMES I HAD THE ISSUE AND THEY COULDN'T FIX IT. ON 07/15/2013, I NOTICED THE AC IS NOT WORKING. IT WAS 85F OUTSIDE. I CALLED THE SERVICE MANAGER AND DROVE THE CAR TO HIM. HE CHECKED THE CAR AND CONFIRMED AC IS NOT WORKING. THEY TOOK THE CAR AND GAVE ME A LOANER. NEXT DAY THEY FOUND SOME ERROR CODES STORED IN THE CAR. WHILE THEY ARE LOOKING INTO THE CODES, AC STARTED WORKING ALL ON ITS OWN. BMW SAYS THE ERROR CODES ARE BOGUS CODES AND INSTRUCTED THE SERVICE MANAGER TO CLEAR THE CODES AND RETURN THE CAR TO ME. SERVICE MANAGER IS DOING HIS BEST TO DIAGNOSE THE ISSUE. BUT WITHOUT BMWS HELP AND SUPPORT HE CAN'T FIX THE ISSUE. IT IS EXTREMELY HOT IN JACKSONVILLE, FL AND WITHOUT AC IN THE CAR IT IS EXTREMELY DANGEROUS TO DRIVE WITH A KID IN THE CAR. *TR

TL* THE CONTACT OWNS A 2011 BMW Z4. THE CONTACT STATED THAT WHILE DRIVING 25 MPH, THE VEHICLE STALLED. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO A DEALER FOUR TIMES BUT THE FAILURE COULD NOT BE REPRODUCED. THE MANUFACTURER WAS NOTIFIED BUT NO ASSISTANCE WAS GIVEN. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 7,005 AND THE CURRENT MILEAGE WAS 12,000.

26SEP12 THE TIRE PRESSURE MONITORING SYSTEM WILL PROVIDE A FALSE FAILURE WHEN THERE IS CERTAIN ELECTRICAL INTERFERENCE (E.G. CELL TOWERS). THIS IS A RECOGNIZED FACT AS NOTED IN THE DRIVER'S MANUAL (P.71). THE ISSUE IS THAT THE SYSTEM FAILS TO RESET AFTER THE INTERFERENCE HAS PASSED AND ALL OF THE FAILURE LIGHTS REMAIN ON FOR AN INDETERMINATE PERIOD OF TIME (FROM 2 HOURS TO 3 DAYS) BEFORE AUTOMATICALLY RESETTING. ABSENT THIS RESETTING THE CAR IS UNSAFE AS, WITHOUT A WARNING SYSTEM FOR TIRE FAILURE (EITHER LOW PRESSURE OR TREAD FAILURE), AN ACCIDENT COULD OCCUR. THE DEALER OFFERED NO SOLUTION AS THE COMPUTER DOES NOT REGISTER A SYSTEM INCIDENT AND ALL SYSTEMS PASSED A COMPUTER CHECK ON 16AUG.. BMW NORTH AMERICA ([XXX]) COULD NOT PROVIDE ANY FURTHER ASSISTANCE. A PROPERLY FUNCTIONING RESET SYSTEM IS NEEDED TO INSURE SAFE OPERATION OF THE MOTOR VEHICLE. THANK YOU FOR YOUR TIME.
