Open the full vehicle complaint log (all categories)THE FUEL PUMP ON MY 2003 CHEVROLET SUBURBAN HAS FAILED. IT SEEMS THAT THIS HAS BEEN A PROBLEM WITH THESE VEHICLES IN THE PAST. I WISH I HAD KNOWN BEFORE. I BOUGHT THE CAR USED IN 2005, WITH APPROXIMATELY 32,000 MILES ON IT. THE "THROTTLE BODY MODULE", "STEERING GEAR", DASH CLUSTER, AND NOW FUEL PUMP HAVE ALL FAILED! THIS HAS MADE ME VERY UPSET WITH THE MANUFACTURER. THE VEHICLE NOW HAS 72,000 MILES ON IT. I THOUGHT BUYING AMERICAN WAS THE RIGHT THING TO DO. NOW I'M WORRIED ABOUT MY 2004 GMC SIERRA. *TR
BEFORE COMPLETE FAILURE, OVER A PERIOD OF A MONTH THE CAR FAILED TO START/TURNOVER. AFTER 5 MINUTES & REPEATED ATTEMPTS CAR WOULD FINALLY START. ON FINAL FAILURE DATE, THE CAR WOULD NOT START EVEN WITH PERIODIC ATTEMPTS OVER 2 DAYS. VEHICLE WAS TOWED TO DEALER. DEALER REPLACED FUEL PUMP & FUEL FILTER WHICH SEEMS TO HAVE FIXED THE PROBLEM. *NM
