DT*: THE CONTACT STATED AT VARIOUS SPEEDS, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE RESTARTED EVERY TIME THE ENGINE STALLED.

DT: CONTACT STATES WHILE DRIVING THE BATTERY LIGHT WILL COME ON, AND THEN THE ENGINE COMPLETELY LOSES POWER, BUT DOES NOT LOSE THE ELECTRICAL POWER. THERE ARE NO INDICATIONS, SUCH AS THE ENGINE HESITATES BEFORE THE VEHICLE STALLS. THIS HAPPENED ON NUMEROUS OCCASIONS.

THE OWNER'S MANUAL STATES IT COULD BE SOMETHING WRONG WITH THE CHARGING SYSTEM. THE VEHICLE HAS TO SIT AND WAIT FOR APPROXIMATELY 3-4 MINUTES BEFORE IT WILL RESTART.

COMPLAINT ON 2001 CHEVROLET SILVERADO EXTENDED-CAB. THE VEHICLE MADE A KNOCKING NOISE WHEN IT WAS FIRST STARTED OR AFTER BEING FULLY WARMED UP. THE CONSUMER TOOK THE VEHICLE TO THE DEALER AND WAS TOLD THAT GM WAS FULLY AWARE OF THE PROBLEM AND THAT THEY WERE IN THE PROCESS OF RE-DESIGNING AND MANUFACTURING A NEW CYLINDER PISTON FOR THE ENGINE BECAUSE IT SEEMED THE PISTONS WERE CAUSING THE PROBLEM.

WE PURCHASED OUR 2001 CHEVROLET SILVERADO 1500 NEW. RIGHT AROUND THE 15,000 MILE MARK WE NOTICED A SLIGHT TAPPING IN THE ENGINE. THIS SEEMED TO ONLY OCCUR ON START UP AND MOSTLY IN THE MORNING WHEN COLD. IT WOULD TAP FOR SEVERAL SECONDS AND THEN DISSIPATE. INITIALLY WE THOUGHT IT WAS A LIFTER, BUT WE HAVE SINCE COME TO FIND OUT IT IS NOT. THE OVERALL DIAGNOSIS IS GM PISTON SLAP. THIS OCCURS WHEN THE PISTONS ARE ILL FITTED TO THE CYLINDER WALLS, AND HENCE YOU GET THE NOISE. WE WERE TOLD IT WAS NOTHING TO BE CONCERNED ABOUT. GM KNOWS OF THE PROBLEM (WELL THEY DON'T CALL IT A PROBLEM), BUT REFUSE TO DO ANYTHING ABOUT IT. THEY SAY THEY HAVE TESTED THESE ENGINES THOROUGHLY AND THE PISTON SLAP CAUSES NO LONG TERM ENGINE PROBLEMS. THE NOISE NOT ONLY BEGAN TO GET LOUDER, BUT ALSO BECAME NON STOP. IT...

LAST YEAR MY TRUCK STARTED DEVELOPING A PAUSE IN THE ENGINE. I HAD MY LOCAL DEALER INVESTIGATE THE PROBLEM. THEY STATED THE FUEL INJECTORS NEEDED CLEANED SO THEY PUT IN AN ADDITIVE.
