1993 GMC Sonoma

DEALER FAILED, GM CALLED BUT STEVE, SAID IT WAS ALL IN MY HEAD. TOOK VEHICLE TO DERRY BROTHERS IN BURLINTON, IOWA , BUT STILL HAVING PROBLEMS, HAD TO PIN THE BRAKE CALIPER PINS AND PUT SET SCREW TO HOLD THEM IN, REPLACED WATER PUMP 3 TIMES BRAKES 24 TIMES, CALIPERS 3 TIMES, FRONT ROTTORS 3 TIMES,AND REAR DRUMS 3 TIMES, ELECTICAL COMPONETS EVERY 6MO TO YEAR, NOW RADIATOR IS GOING GO THROUGH 4 TIRES EVERY 4 TO 6 MO,AND OTHER PROBLEMS WITH DEALER!!!!!!

THE EGR VALVE GETS FULL OF CARBON AND, ABOUT EVERY 1000 MILES, CAUSE THE TRUCK TO QUIT AND THE BRAKES TO STOP OPERATING, PUTTING OUR SAFETY AT RISK. I BOUGHT THE TRUCK USED FROM MY FATHER-IN-LAW AND HE DID NOT ENCOUNTER THIS PROBLEM. I HAVE TAKEN THE TRUCK TO THE SAME MECHANIC THAT HE DID AND HE HAS CLEANED OUT THE CARBON TWICE NOW. BUT I TOOK IT TO THE ORIGINAL DEALER AND THEY FOUND THE SAME PROBLEM AND SAID THEY HAVE FOUND THAT AROUND THE HIGH 90,000 AND 100,000 MILEAGE MARK, THIS EGR VALVE IS A PROBLEM IN THIS TRUCK ENGINE. IT CONTINUES TO BE A MORE FREQUENT PROBLEM, ESPECIALLY OBVIOUS ON LONGER TRIPS. THE TRUCK SIMPLY QUITS WHEN YOU DECELERATE TO COME TO A STOP AND THE BRAKES GIVE OUT. YOU HAVE TO CONSTANTLY RESTART THE ENGINE OR TRY COASTING INTO THE STOP, PUT THE TRUCK IN NEUTRAL AND KEEP THE ENGINE REVING, SO IT HOPEFULLY WON'T STOP. *AK

WHEN DRIVING VEHICLE AT VARIOUS SPEEDS, ABS BRAKES WOULD FAIL TO STOP VEHICLE. WOULD FADE OUT, AND STOPPING DISTANCE HAS BEEN INCREASED. VEHICLE ALSO HESITATED IN REVERSE. WHEN IN DRIVE POSITION WOULD RAMBLE & LOSE POWER. ALSO, THERE ARE DEFECTIVE VALVES IN ENGINE. ALSO DEFECTIVE DRIVESHAFT RUBBER BEARINGS CAUSE VEHICLE TO VIBRATE. HAVE TAKEN VEHICLE TO MIDAS & NOT DEALERSHIP. THE PROBLEM COULD NOT BE SOLVED. *AK
