VEHICLE WOULDN'T PASS INSPECTION. FUEL INJECTOR WAS NO GOOD. *AK THE FAILED FUEL INJECTOR WAS THE SEQUENTIAL CENTRAL PART FUEL INECTION UNIT. *YH

POPPITS LEAKING FUEL ON CENTRAL PORT INJECTORS CAUSING FUEL TO RUN RICH WHICH CREATES CARBON BUILD UP IN EGR VALVE. THIS CAUSES BRAKES TO MALFUCTION BECAUSE OF VACUUM. VALVE HAS BEEN REPLACED OR CLEANED 4 TIMES. GMC HAS BEEN ALERTED AND I AM WAITING FOR A RESPONSE FOR COST OF REPAIRS, EST. $800. WHEN THE WARRANTY WAS VALID THEY REPLACED THE EGR VALVE, I FEEL THEY PROLONGED THE PROBLEM AT THE EXPENSE OF MY FAMILY'S SAFETY AND MONEY. THE WARRANTY IS NO LONGER VALID BUT THE PROBLEM STILL EXIST. I FEAR FOR MY SAFETY AND THE SAFETY OF OTHERS IN MY PATH. GMC SHOULD ADDRESS THE REAL PROBLEM AND MAKE MY VEHICLE SAFE! PLEASE RESPOND IF OTHERS ARE HAVING THE SAME COMPLAINT, I NEED HELP. I AM A DISLOCATED WORKER AND I CAN NOT AFFORD TO TRADE OR FIX MY PROBLEM!

FUEL INJECTION SYSTEM , LOCATED INSIDE INTAKE MANIFOLD, IS LEAKING AND SPRAYING RAW FUEL ON MANIFOLD. DEALER CLAIMS ONLY SOLUTION IS TO REPLACE COMPLETE FUEL INJECTION SYSTEM. *AK *ML

1. SEAT BELT REPLACED PREVIOUSLY BY DEALER OUT OF STANDARD WARRANTY PERIOD. THE SAME PROBLEM HAS OCURRED AGAIN WITH THE BELT RETRACTOR COIL SPRING WEARING THROUGH THE PLASTIC HOUSING PREVENTING THE BELT FROM RETRACTING AND HOLDING THE PASSENGER IN PLACE. 2. FUEL PUMP WAS REPLACED PREVIOUSLY DURING STANDARD WARRANTY PERIOD. FAILS TO PROVIDE SUFFICENT PRESSURE TO START THE ENGINE ESPECIALLY WHEN COLD.

WHILE DRIVING ON STATE HIGHWAY FUEL PUMP FAILED, CAUSING LOSS OF POWER AND POWER STEERING. *AK ENGINE DIED WITHOUT WARNING, ENGINE WOULD ONLY RUN AT HIGH RPMS, EVENTUALLY VEHICLE WOUDL NOT START AT ALL, DEALER SERVICE MANAGER STATED THAT PUMP REQUIRES HALF A TANK OR MORE OF GASOLINE TO COOL PUMP AND PREVENT THIS FAILURE. *SLC
