2007 AUDI Q7 Electronic Stability Control Esc Problems

CAR STALLED WHILE DRIVING ON HIGHWAY AND ESP/ABS LIGHT CAME ON - WAS TOLD BY DEALER WILL HAVE TO REPLACE THE ENTIRE ABS CONTROL MODULE FOR $2800! TO DIAGNOSE THIS TOOK 2 DAYS FOR THE DEALER AND EVEN THEN THEY ARE NOT 100% SURE THE REPLACEMENT WILL FIX THE ABS ISSUE. HAVE ALREADY PAID 500+ IN LABOR DIAGNOSIS! *TR

AUDI Q7 4.2L WITH 34200 MILES LOST RPM ON HIGHWAY, SPEED SUDDENLY DROPPED FROM 62MPH TO 22 MPH, WHEN ESP LIGHT CAME ON AND ENGAGED THE ABS. THE CAR BEHIND COULD BARELY STOP, DISTURBING THE ENTIRE TRAFFIC. FREQUENT PROBLEMS WITH THE ESP (ELECTRONIC STABILIZATION PROGRAM), THE ESP LIGHT WILL COME ON AND OFF MULTIPLE TIMES, MOSTLY ON, ALONG WITH THE MALFUNCTION INDICATOR LAMP. WHEN ESP LIGHT COMES ON, THE CAR IS JERKING AND IT INVOLVES THE ABS (ANTI-LOCK BRAKE SYSTEM), ALTHOUGH THE WEATHER/STREETS CONDITIONS ARE VERY GOOD (DRY, PAVED STREETS, SUMMER SUNNY DAYS). TOOK CAR TO THE DEALER 3 TIMES, DID NOT FIX THE PROBLEM. I WAS TOLD I AM THE FIRST ONE WHO EXPERIENCED THIS KIND OF PROBLEM, AND THAT I AM THE "GUINEA PIG" FOR THEM. IT IS CLEAR THAT THIS CAR REPRESENTS A GREAT POTENTIAL DANGER WHILE IN TRAFFIC. TODAY, I WAS ALMOST INVOLVED IN AN ACCIDENT....

I CURRENTLY OWN A 2007 AUDI Q7 3.6 AND BELIEVE THERE IS A SAFETY ISSUE WITH ALL 2007 3.6 VEHICLES. THE VEHICLE IS ADVERTISED TO HAVE THE TOWING ABILITY TO TOW UP TO 6600LBS. ON THREE SEPARATE OCCASIONS WHILE TOWING A 435LB ALUMINUM TRAILER THE CHECK ENGINE LIGHT CAME ON ALONG WITH THE EPC (ELECTRONIC POWER CONTROL) LIGHT AND THE CAR GOES INTO A SAFE MODE WHICH WILL NOT ALLOW YOU TO GO OVER 3000RPMS. THIS PROBLEM ONLY OCCURS WHILE TOWING FOR OVER AN HOUR BUT WHEN THE SAFE MODE IS INSTALLED THE CAR HAS NO POWER AND WITH A TRAILER STILL HOOKED UP THE CAR HAS TROUBLE GOING OVER 45MPH. THIS IS A VERY DANGEROUS SITUATION ESPECIALLY ON THE HIGHWAY WHEN TRUCKS ARE PASSING YOU DOING 70MPH. MY Q7 WAS IN THE DEALERSHIP THREE TIMES FOR THIS PROBLEM AND I'M STILL NOT SATISFIED THAT THE PROBLEM HAS BEEN CORRECTED....

WHILE DRIVING IN DRY/FAIR WEATHER CONDITIONS AND AT HIGHWAY SPEEDS (50 AND 70 MPH) THE ESP WARNING LIGHT CAME ON AND ENGAGED THE ABS SYSTEM FOR NO APPARENT REASON. IT CREATED A LOSS OF CONTROL OF THE AUDI Q7 4.2 UNTIL I TURNED OFF THE ESP SYSTEM AS I EXITED THE FREEWAY TO STOP AND THEN RESTART THE VEHICLE. THIS HAS HAPPENED THREE TIMES IN THE PASTED 100 MILES AND 3 MONTHS. THE SELLING DEALER FOUND NO CODES AND NOTHING HAS BEEN RESOLVED. THIS IS NOT A SAFE SITUATION FOR ME, AND AUDI HAS OFFERED NO SOLUTION TO THE DEALER TECH TO DATE. *TR
