JUNE 2006 THE FUEL PUMP STOPPED WORKING WHEN I WAS DRIVING ON THE FREEWAY, I WAS TOWED TO THE GARAGE WE NORMALLY USE FOR MAINTENANCE. THEY REPLACED THE FUEL PUMP WE DID NOT PURSUE THIS UNDER THE ORIGINAL WARRANTY ON THE VEHICLE - BIG MISTAKE! IN JANUARY 2009 THE FUEL GAUGE STOPPED WORKING AND AGAIN WE STOPPED ON THE FREEWAY AND HAD TO BE TOWED. THIS TIME IT WAS THE FUEL GAUGE. THE FUEL PUMP CANNOT BE REPLACED UNDER WARRANTY AS THIS WAS JUST FOR ONE YEAR. WE WERE ADVISED TO USE THE TRIP MILEAGE TO FILL FUEL TANK. WE HAVE HAD TWO FAILURES BOTH AT APPROXIMATELY 30MTHS. *TR

I WAS IN AN ACCIDENT ON JULY 3RD IN A 2003 SUBURBAN. AT THE TIME OF THE ACCIDENT, I FELT I WAS A SAFE DISTANCEE BEHIND THE CAR IN FRONT OF ME. THERE WAS CONSTRUCTION ON 635 IN DALLAS AND A CAR STOPPED IN FRONT OF THE CAR IN FRONT OF ME. WHEN I APPLIED THE BRAKES AND I REACTED VERY QUICKLY, I FELT LIKE THE BRAKES DID NOT REACT CORRECTLY AND I RAN INTO THE CAR IN FRONT OF ME. I WAS IN DISBELIEF THAT THE ACCIDENT HAD OCCURED. I HAD JUST PURCHASED THE SUBURBAN AND ATTRIBUTED THE DELYED STOPPING TIME TO THE SIZE AND WEIGHT OF THE VEHICLE. SINCE THAT ACCIDENT, I HAVE HAD (2) SITUATIONS WHERE I NEEDED TO HIT THE BRAKES VERY QUICKLY AND BOTH TIMES I FELT LIKE THE BRAKES WERE NOT WORKING CORRECTLY. I JUST NOTICED THAT GM PUT OUT A RECALL FOR 2002 SUBURBAN AND WAS CURIOUS IF THERE WERE ANY OTHER SIMILAR PROBLEMS REPORTED WITH THE 2003 SUBURBAN. THANKS, STEVE BURKE. *JB 3770 PALLOS VERDAS DR DALLAS, TX 75229 214.335.5523. *JB
