1999 BMW 540I

MY SON WAS DRIVING HOME IN RUSH HOUR TRAFFIC ON CONNECTICUT AVE. IT WAS RAINING RATHER HARD AND VISIBILITY WAS LOW. MY SON ALL OF THE SUDDEN SMELLED SMOKE COMING THROUGH THE VENTS AND THE ENGINE SHUT DOWN. IT WOULD NOT RESTART. HE HAD TO PUSH IT OFF THE ROAD INTO A SERVICE STATION DUE TO THE HIGH VOLUME OF TRAFFIC. THE CAR WAS TOWED THAT EVENING TO MY REPAIR SHOP WHERE IT WAS DIAGNOSED THAT THE THERMOSTAT HOUSING SENSOR FAILED WHICH MELTED THE WIRING HARNESS AND DAMAGED OTHER ELECTRICAL SENSORS ON THE ENGINE. *TR

THE DRIVER OWNS A 1999 BMW 540I WITH 72,579 MILES. OVER THE PAST TWO MONTHS THE DISC BMW ELECTRONIC STABILITY CONTROL SYSTEM ICON AND THE AMBER ABS AND BRAKE LIGHTS ILLUMINATED IN ONE OF TWO SCENARIOS: (1) JUST AFTER A NEW IGNITION CYCLE, (2) DURING NORMAL DRIVING. ONCE THESE WARNINGS ILLUMINATED THE DSC, ABS, AND TRACTION CONTROL SYSTEMS BECOME NON-FUNCTIONAL. UNTIL RECENTLY, THE WARNINGS WOULD GO OUT AFTER 5-10 IGNITION CYCLES. NOW THEY WERE ON CONTINUOUSLY.*AK NEXT TO SEATBELTS, I STRONGLY BELIEVE ESC IS THE MOST SIGNIFICANT DEVELOPMENT IN AUTOMOTIVE SAFETY. AS SUCH, I FIND IT VERY DISCONCERTING THE SYSTEM ON MY VEHICLE HAS MALFUNCTIONED. RESEARCHING THE TOPIC ON THE VARIOUS BMW FORUMS HAS LEAD ME TO BELIEVE MY SITUATION IS NOT AN ISOLATED ONE; THAT MANY MODEL YEAR 1999-2000 5-SERIES BMWS HAVE ALSO BEEN AFFECTED. ESC MALFUNCTIONS CAN HAVE VERY NEGATIVE IMPACT ON VEHICLE SAFETY. IN JUSTIFYING THE RATIONALE FOR ITS RECENT MANDATE OF ESC, NHTSA ESTIMATES ESC WILL REDUCE SINGLE VEHICLE CRASHES AND ROLLOVERS BY 34 AND 71 PERCENT, RESPECTIVELY. THE AGENCY ESTIMATES THIS TECHNOLOGY WILL SAFE UP TO 9600 LIVES PER YEAR. PLEASE FEEL FREE TO CONTACT ME IF YOU REQUIRE ADDITIONAL INFORMATION. THANK YOU.

I THINK THIS IS RIDICULOUS THAT THE 60,000 DOLLAR BMW 5 SERIES WITH DSC AND ABS CONTINUALLY HAVE ABS CONTROL MODULE FAILURES. THE PART IS OBVIOUSLY A DESIGN FLAW AND THE COMPANY SHOULD BE FORCED TO REPAIR OR REPLACE UNITS FREE OF CHARGE. THIS IS OBVIOUSLY A SAFETY ISSUE SINCE THE MODULE FAILURE CAUSES THE TRACTION CONTROL AND ABS TO FAIL. THIS IS COMMON IN MODEL YEARS 98,99,AND 2000. *NM

ABS WARNING AND DSC LIGHT IS ON INDICATING FAILURE OF ABS ELECTRONIC MODULE. ABS AND DSC IS NO LONGER OPERABLE. THIS IS A SAFETY ISSUE SINCE THE CAR WILL NO LONGER HAVE ABS AND DYNAMIC STABILITY CONTROL SYSTEM IN OPERABLE CONDITION. IT IS UNKNOWN IF BRAKE COULD BE RANDOMLY ACTIVATED BY THE FAILED ABS MODULE WHILE DRIVING. COMMON FAILURE ON 1999 OR PLUS 5-SERIES BMW BASED ON USER DISCUSSION ON INTERNET. THE FAILURE IS TEMPERTURE RELATED. THE HIGHER THE TEMPERTURE, THE QUICKER THE WARNING LIGHT WILL COME ON. *NM

DURING A DOWN SHIFT, MY CAR SOMETIMES JUMP FORWARD A FOOT OR SO AND MAKES A THUMP DOWN SHIFTING NOISE. THIS FORCES ME TO APPLY THE BREAK QUICKLY. JUST A WEEK AGO, I HIT A CURVE BECAUSE OF THIS DEFECT AND THE BOTTOM BUMPER COVER OF THE CAR GOT HIT AND BECAME CRACKED! LUCKILY THIS PROBLEM IS RARE. THIS IS ABOUT 4TH FAILURE IN A SPAN OF 10 MONTHS. FOR ABOUT 10 MONTHS, MY CAR ALSO STALLS (ENGINE LOSES POWER) DURING A SLOWDOWN. USUALLY THIS HAPPENS WHEN I SLOW TO MAKE A RIGHT TURN. I NEARLY GOT INTO AN ACCIDENT FEW TIMES THIS MONTH BECAUSE MY CAR STALLED IN AN INTERSECTION DURING A TURN. THIS OCCURS ABOUT 0-2 TIMES PER MONTH AND EACH TIME I TAKE THE CAR TO THE DEALER, IM INFORMED THAT THEY SEE NO PROBLEMS OR THE PROBLEM IS FIXED. IVE REPORTED THIS COMPLAINT TO BMW CUSTOMER SERVICE AND ASKED IF THEY ARE AWARE OF THIS PROBLEM. THEYVE TOLD ME NO.
