2002 CHEVROLET SUBURBAN 1500 Engine And Engine Coolingengine Problems

TL*THE CONTACT OWNS A 2002 CHEVROLET SUBURBAN 1500 LT. WHILE DRIVING 35 MPH THE VEHICLE STALLED. THE VEHICLE WAS DRIVEN ONTO THE SIDE OF THE ROAD. HE WAITED A FEW MINUTES AND WAS ABLE TO RESTART THE VEHICLE. NEITHER THE DEALER NOR THE MANUFACTURER WERE NOTIFIED. THE FAILURE MILEAGE WAS 114,346.

WHILE DRIVING ON THE FREEWAY MY 2002 SUBURBAN WITH A 5.3L FLEX FUEL EQUIPPED VEHICLE JUST WOULD STALL WITH OUT WARNING AND CAUSE ME TO LOSE ALL POWER STEERING AND OTHER ITEM RELATED TO THE ENGINE RUNNING. I HAVE TO WAIT FOR THE VEHICLE TO COOL DOWN BEFORE BEING ABLE TO RESTART IT. NO CODE WOULD SHOW ON THE ON BOARD COMPUTER AND AFTER LOOKING AT OTHER RECALLS IT POINTED TO THE CRANKSHAFT POSITION SENSOR GOING BAD. I AM GOING TO CHANGE IT OUT IN THE MORNING. I HAVE READ OTHERS HAVING THIS SAME ISSUE IN THIS YEAR MODEL AND THINK CHEVY SHOULD DO SOMETHING ABOUT IT. *TR

WHILE DRIVING SUBURBAN ON A LONG TRIP OVER 2 HOT DAYS, ENGINE QUIT WITHOUT WARNING ONCE EACH DAY AFTER MANY HOURS OF DRIVING (5 PEOPLE WITH LUGGAGE, NO TRAILER). FIRST DAY OCCURRENCE WAS AFTER DRIVING IN CITY TRAFFIC WITH MANY STOPLIGHTS BUT SPEED WAS ABOUT 60 MPH AT THE TIME AND QUICKLY LOST POWER AND DIED. SECOND DAY WAS AT SUSTAINED 70+MPH AND QUIT SUDDENLY. BOTH TIMES NEEDED TO PULL OVER AND TURNED OFF FOR A MINUTE AFTER FAILURES AND RESTARTED ON 2ND TRY AND CONTINUED ON FOR ANOTHER 20+ MILES BEFORE STOPPING FOR THE DAY (FIRST DAY) AND STOPPING FOR DINNER (2ND DAY). FUEL IN GAS TANK WAS HALF FULL ON FIRST DAY AND 3/4 ON SECOND DAY. THIS VEHICLE EXHIBITED SAME FAILURE NUMEROUS TIMES 2 YEARS PREVIOUSLY ON HOT DAY PULLING TRAILER. *TR

WHILE DRIVING AT HIGHWAY SPEEDS WITH MY 2002 CHEVROLET SUBURBAN LS WITH 45,000 MILES ON IT, I ENCOUNTERED A COMPLETE ENGINE FAILURE. THE VEHICLE WOULD COAST UNTIL I REACHED A SPEED OF 30MPH., I WOULD PLACE THE VEHICLE IN NEUTRAL AND ATTEMPT TO RE-START THE ENGINE. AFTER SEVERAL ATTEMPTS, THE VEHICLE WOULD RE-START, ACCELERATE TO 70 MPS. THIS WOULD OCCUR INTERMITTENT OVER AND OVER THROUGH MY TWO DRIVING TRIP. THE ACTUAL NUMBER OF TIME THE ENGINE FAILED WAS 14. THIS CAUSED A VERY SERIOUS SITUATION, BECAUSE WITHOUT ENGINE POWER, I HAD NO POWER BRAKES, STEERING OR THE ABILITY TO MAINTAIN SPEED, WHICH RESULTED IN ME LOCATING THE ROAD SHOULDER IMMEDIATELY! I CONTACTED THE DEALER I USE REGULARLY AND THEY INFORMED ME THIS IS THE FIRST TIME THEY HAVE EVER HEARD OF THIS. HOWEVER, AFTER RESEARCHING THE INTERNET I DISCOVERED THROUGH FORUMS THIS IS A PROBLEM THAT MANY PEOPLE ARE EXPERIENCING....

#5 CYLINDER 1164 MISFIRES. COLLAPSED LIFTER, BROKEN RINGS. THE DEALERSHIP WENT ON FISHING EXPEDITION, CHARGING ME $271.82 FOR UNNECESSARY WORK (NEW SPARK PLUG AND WIRES). WENT FOR SECOND DIAGNOSES, CORRECTLY DIAGNOSED THIS TIME INDICATING THE ABOVE. MECHANIC CONTACTED GMPP (EXTENDED WARRANTY),TOLD GMPP THAT THE ENGINE SHOULD BE REPLACED. THE MECHANIC WAS ADVISED TO TELL ME TO RETURN TO DEALERSHIP FOR SERVICE. *NM
