I WAS DRIVING HOME FROM MY SONS FOOTBALL PRACTICE. I WAS IN SECOND GEAR GOING APPROX. 20 MPH. THE CAR SLOWLY STARTED TO DECELERATE, UNTIL IT STOPPED COMPLETELY AT THE CURB. I COULD NOT GET IT STARTED. AFTER SPENDING $50 ON A TOW, AND $160 TO HAVE THE PROBLEM ANALYZED, I WAS TOLD IT WAS MY FUEL PUMP AND FILTER THAT NEEDED TO BE REPLACED. I WAS QUOTED $1160 TO FIX IT. I'M IN THE PROCESS OF LOCATING A CHEAPER MECHANIC, BUT THE LOWEST QUOTE SO FAR HAS BEEN $700. MAKING MY GRAND TOTAL A MINIMUM OF $910. *JB

HAD CAR TOWED, MECHANIC COULDN'T FIND THE PROBLEM BUT THE CAR STARTED AGAIN. CAR RAN FINE FOR MONTHS WITH NO INDICATION THERE WAS A PROBLEM. SECOND FAILURE SEPT 2007 (110,000), DRIVING ON THE INTERSTATE IN HIGH TRAFFIC HIGH SPEED, CAR STALLED OUT AND MANAGED TO GET TO THE SHOULDER WITHOUT GETTING HIT. WOULD NOT START AGAIN. WE HAD THE CAR TOWED AND HAVE TO REPLACE THE FUEL PUMP. IT HAS TO BE DEFECTIVE AND IS VERY DANGEROUS. I JUST HOPE NO ONE HAS TO DIE ON AN INTERSTATE BECAUSE OF THIS BEFORE A RECALL IS MADE. COST OF REPAIR AFTER EXTENSIVE SEARCH AND NOT USING GM PARTS OR DEALER SERVICE WAS EST. $360 + TOW. OLD PART WILL BE SITTING HERE WAITING FOR A RECALL. *TR

ON MAY 14, 2004 THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION (PE04-043) BASED ON CONSUMER COMPLAINTS ALLEGING THAT THE BRAKE/TAIL TURN SIGNAL LAMPS WOULD NOT OPERATE PROPERLY WHEN EITHER THE TAIL LIGHTS WERE TURNED ON, THE BRAKE PEDAL WAS DEPRESSED, OR WHEN THE TURN SIGNAL SWITCH WAS ACTIVATED.ON SEPTEMBER 14, 2004 ODI UPGRADED PE 04-043 TO AN ENGINEERING ANALYSIS (EA04-028).GM STATES THAT SOME BRAKE/TAIL/TURN SIGNAL LAMP BULBS CAN PREMATURELY BECOME INOPERATIVE DUE TO EXCESSIVE HEAT BUILDUP WITHIN THE BULB SOCKETS.THE CAUSE OF THE EXCESSIVE HEAT BUILD UP WAS DETERMINED TO BE A LACK OF THERMAL GREASE PLACED IN BETWEEN THE BULB AND THE SOCKET. BY LETTER DATED OCTOBER 27, 2004 GM NOTIFIED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA # 04V524) COVERING ALL MY 2003 VEHICLES.GM DEALERS WILL INSPECT THE REAR LAMP BULB SOCKET ASSEMBLIES AND APPLY THERMAL GREASE TO THEM OR REPLACE THEM WITH NEW ASSEMBLIES WITH THERMAL GREASE ALREADY ATTACHED.MODEL YEAR 2004 AND NEWER VEHICLES HAVE THE THERMAL GREASE INSTALLED FROM THE FACTORY. THE ACTION TAKEN BY GM IS SUFFICIENT TO RESOLVE THE ISSUES RAISED BY THIS INVESTIGATION.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.
