WHILE TRAVELING ON BUSY STREET, OUR 2002 CHEVROLET SUBURBAN SUDDENLY WAS WITHOUT POWER. PRESSING ON ACCELERATOR DID NOTHING AND VEHICLE COMPLETELY STALLED WHEN BRAKE WAS APPLIED. THIS LEFT US ATTEMPTING TO NAVIGATE FROM BUSY STREET WITH OUR THREE KIDS IN THE CAR WITH NO POWER STEERING OR BRAKES! WE WERE 140 MILES FROM HOME AND WHEN WE ATTEMPTED TO DRIVE BACK HOME, THIS PROBLEM OCCURRED AGAIN. THIS TIME ON BUSY FOUR LANE ROAD WITH LOTS OF TRAFFIC. THE VEHICLE STALLED OUT AGAIN LEAVING US ON SIDE OF BUSY ROAD AT ON RAMP LOCATION. THIS WAS NOT FIRST TIME THAT THIS HAS OCCURRED. WE HAVE HAD 5 OTHER INCIDENCES WITH THIS VEHICLE. GM IS NO HELP.

2002 CHEVROLET SUBURBAN 1500 LOSES ACCELERATION POWER ON HIGHWAY. VEHICLE DOES NOT RESPOND TO ACCELERATION ATTEMPTS. ONCE BRAKE IS APPLIED VEHICLE COMPLETELY STALLS AND HAS NO POWER STEERING OR BRAKES. THIS HAS OCCURRED IN HIGHWAY DRIVING AT 70 MPH IN HEAVY TRAFFIC AREAS. THERE IS NO CONSISTENCY IN OCCURRENCES. HAPPENED AUGUST 2007 , AND DEC. 2007, SEPT. 2009 AND NOVEMBER 2009. CHECK ENGINE LIGHT DOES NOT COME ON. CAN NOT BE DIAGNOSED ON COMPUTER. GM MECHANICS CAN NOT FIGURE OUT PROBLEM UNLESS IT HAPPENS TO THEM. GM REFERS US TO DEALERSHIP FOR DIAGNOSING AND REPAIRS UNDER THESE CONDITIONS. DON'T HAVE THE MONEY TO PUT IN REPAIRS THAT MAY OR MAY NOT CORRECT PROBLEM. HAVE FOUND MANY COMPLAINTS ON INTERNET DETAILING THIS PROBLEM BUT GM DENIES ANY KNOWLEDGE OF THIS PROBLEM. NOTICED THAT 2001 CHEVY SUBURBANS HAVE HAD A RECALL OF CRANKSHAFT POSITION SENSOR AND THAT SYMPTOMS ARE SIMILAR TO MY...

ON MULTIPLE OCCASIONS MY 2002 CHEVROLET SUBURBAN STALLED WHILE DRIVING ON THE FREEWAY. AFTER SEVERAL MINUTES THE TRUCK WOULD RESTART. THE CHEVY DEALER SAID THERE WAS NOTHING THEY COULD DO SINCE THEY WOULD NOT BE ABLE TO DUPLICATE THE CONDITION. IT DOES NOT TRIGGER A CHECK ENGINE SIGNAL. IT USUALLY HAPPENS AFTER LONG PERIODS OF FREEWAY DRIVING WITH NO WARNING. THIS IS NOT A LOW FUEL ISSUE. I SUSPECT IT IS A CRANK POSITION SENSOR FAILING AFTER RESEARCHING THE ISSUE ON THE INTERNET. *JB
