1999 GMC SIERRA 1500 Complaints

RETURNING HOME TURNED ONTO PROGRESS DR. XENIA, OH. HAD TO MAKE A RAPID STOP (CAR PULLED OUT IN FRONT OF ME), BRAKES FELT SOFTER, PULLED INTO SIOUX DR. XENIA, OH. TO PICK UP WIFE AND HEAD A FAMILY MEMBERS HOUSE. DROVE UP SIOUX DR. STOPPED AT THE STOP AND TURNED ONTO MAUMEE DR., WENT TO PUSH ON BRAKE PEDAL IT WENT TO THE FLOOR, DROVE BACK HOME AND FOUND BRAKE FLUID DRIPPING ON THE DRIVEWAY. FOUND THAT BRAKE LINE NEXT TO FRAME OF TRUCK WAS LEAKING. LATER FOUND BRAKE FLUID ON FRONT DRIVEWAY WHERE I HAD STOP EARLIER. *TR

FOUND THE EXHAUST MANIFOLD BOLTS ON BOTH SIDES OF THE ENGINE SNAPPING OFF FOR NO REASON AT ABOUT 65K MILES. WHEN I ASKED THE LOCAL DEALER ABOUT THIS THEY STATED THEY WOULD NEED TO REMOVE AND RESET THE ENGINE HEADS IN ORDER TO REMOVE THE BROKEN BOLTS. I DID NOT HAVE THEM REPAIR THE PROBLEM DUE TO THE COST THEY QUOTED. I NOW HAVE THREE BOLTS ON EACH SIDE WHICH HOLD THE MANIFOLDS IN PLACE. THE PROBLEM SEAM TO HAPPEN AT THE CHANGE OF THE SEASON FROM FALL TO WINTER. IN THE EXTREME COLD WEATHER, ON A COLD START UP, THERE IS AN OBVIOUS EXHAUST LEAK. AS THE ENGINE HEATS UP THE LEAK DOES DISAPPEAR. THIS IS A SAFETY HAZARD DUE TO THE FACT IF THE ENGINE EXHAUST BLOW BY IS TRANSFERRED INTO THE CAB THE DRIVER COULD BECOME UNCONSCIOUS AND DEATH COULD OCCUR. *TR

ON APRIL 15 2010, AS I WAS BRINGING MY VEHICLE TO A STOP, THE BRAKE PEDAL TRAVELED ALL THE WAY TO THE FLOOR. WHEN I GOT UNDER THE VEHICLE TO EXAMINE IT I SAW THE REAR RIGHT BRAKE LINE WAS LEAKING BRAKE FLUID BADLY DUE TO A BREAK IN THE METAL BRAKE LINE. AGAIN ON 2/27/2011, I WAS STOPPING MY VEHICLE AT A STOP SIGN AND THE SAME THING HAPPENED AT A LOW SPEED. ONLY THIS TIME IT WAS A FRONT RIGHT BRAKE LINE. LUCKILY IN MY INCIDENTS THERE WERE NO ACCIDENTS OR INJURIES OR DEATHS, BUT THIS IS A SERIOUS ISSUE WITH THESE VEHICLES, ALL THE REST OF MY BRAKE LINES ARE IN VERY POOR CONDITION AT THIS TIME AND WILL ALSO NEED TO BE CHANGED SO I FEEL SAFE DRIVING MY TRUCK, ESPECIALLY WHEN MY FAMILY IS WITH ME. I HAVE OWNED TWENTY PLUS VEHICLE IN MY TIME AND EVEN SOME OF THEM WHERE GENERAL MOTORS, BUT I HAVE NEVER SEEN A VEHICLE DETERIORATE THE WAY THAT THIS ONE IS.
