1996 Chevrolet Suburban

ENGINE STOPS RUNNING WITH NO WARNING. THIS CAN OCCUR WHILE IDLING, ACCELERATING, CRUISE SPEED, ANY TIME OF YEAR, ANY WEATHER CONDITION. SOMETIMES IT WILL RESTART BY SHIFTING TO N AND RE-CYCLING IGNITION SWITCH WITHOUT HAVING TO STOP OR LEAVE ROAD. SOMETIMES, AS IS THE PRESENT CASE, IT WILL NOT RESTART. I HAVE OWNED THIS VEHICLE SINCE NEW. THIS HAS BEEN AN ONGOING PROBLEM BEGINNING AT 80,000 MI. MANUFACTURER EXTENDED WARRANTY TO 120,000 MILES, HAS CONTINUED BEYOND WARRANTY PERIOD AND IS A SOURCE OF SAFETY CONCERN. THIS HAS OCCURRED ON INTERSTATE HIGHWAYS, IN THE MIDDLE OF BUSY (HIGH SPEED INTERSECTIONS). DEALER PERFORMED NUMEROUS ATTEMPTS TO FIX PROBLEM, BUT THEY CONTINUED. I HAVE HAD THIS VEHICLE TO THE DEALER MORE TIMES THAN I CAN COUNT. I HAVE HAD ASSISTANCE FROM OTHER PROFESSIONAL SOURCES (AFTER THE WARRANTY PERIOD WAS OVER AND WAS CONVINCED THAT DEALER/MFG. COULD NOT OR WOULD NOT FIX THE PROBLEM. I HAVE REPLACED FUEL INJECTION PUMP 2 TIMES MINIMUM, HAVE REPLACED PMD/FSD AT LEAST 5 TIMES, REPLACED AUXILIARY/LIFT PUMP TWO TIMES, HAVE DRAINED AND CLEANED FUEL TANK 2 TIMES. MOST RECENT INJECTION PUMP REPLACEMENT WAS IN AUG/SEPTEMBER 05 (7000 MILES AGO). I HAVE SPENT AT LEAST $5000 TRYING TO FIX THIS PROBLEM. ENGINE STOPPED LAST MONDAY AND WILL NOT RESTART. AM SURPRISED NO COMPLAINT HAS BEEN FILED BEFORE NOW.*JB

I HAVE REPLACED THE INTAKE MANIFOLD GASKET TWICE NOW FOR MY 1996 CHEVROLET SUBURBAN. BOTH TIMES IT HAS COST ME OVER $650.00. BOTH MECHANICS TOLD ME THAT THEY SEE THESE AT LEAST TWICE A WEEK ON THE 5.7 ENGINES. THEY KNEW EXACTLY WHAT WAS WRONG. THEY ACTUALLY LAUGHED WHEN I ASKED THEM IF IT WAS SET UP AS A RECALL ITEM FOR THIS ENGINE. *JB

I HAVE OWNED 2 1996-1997 CHEVROLET SUBURBAN AND HAVE HAD THE INTAKE MANIFOLD LEAK ON BOTH AT ABOUT 85000 MILES. I DID A LITTLE LOCAL RESEARCH AND FOUND THAT THIS IS A VERY COMMON PROBLEM FOR THE VORTEC 5.7 ENGINE. WHEN I CALLED THE DEALERSHIP ABOUT A COOLANT LEAK FROM THE ENGINE AREA, THE SERVICE WRITER SAID THIS WAS MOST LIKELY THE INTAKE MANIFOLD BECAUSE THEY GET THAT ALL THE TIME. TOAY, I NOTICED A COOLANT PUDDLE IN MY DRIVE WAY AND UPON LOOKING INTO IT, MY LATEST 1996 SUBURBAN WITH A VORTEC 5.7 IS LEAKING AT THE INTAKE MANIFOLD. THIS IS A COSTLY PROBLEM TO THE CONSUMER. IT COSTS APPROXIMATELY $500.00 TO HAVE THIS DONE. I NOW MUST MAKE THE DECISSION TO HAVE IT FIXED AT THE DEALER FOR $500 OR TO DO IT MYSELF FOR ABOUT $150.00 AND A DAY OF HEADACHES. *AK

LATENT DEFECTS AND THE GMC SUBURBAN.*MR THE CONSUMER HAS EXPERIENCED SEVERAL PROBLEMS WITH VEHICLE. THE FRONT OUTPUT SHAFT SEALS HAD TO BE REPLACED, THE INTAKE MANIFOLD GASKET HAD TO BE REPLACED, AND THE AC HEATER KNOB HAD TO BE REPLACED. WHEN THE DEALER WAS NOTIFIED THEY FAIL TO FIX PROBLEMS AND HE CONSUMER HAD TO PAY AT THERE OWN EXPENSE. PLEASE RESPOND PROMPTLY IN HELPING TO RESOLVE MATTER. *CB
