2003 GMC ENVOY Power Train Problems

SHIFT CABLE BROKE BETWEEN THE SHIFTER AND THE TRANSMISSION WHILE SHIFTING FROM DRIVE TO REVERSE TO PARK ON A STREET. IF THIS HAD HAPPEN WHILE SHIFTING DOWN GEAR TO LOWER SPEED WHILE DRIVING DOWN A HILL, A LOSS OF CONTROL OF THE VEHICLE WOULD HAVE HAPPEN THAT WOULD HAVE LED TO A CRASH WITH EXTREME PROPERTY DAMAGE AND MOST LIKELY DRIVER AND PASSENGER INJURY AND POSSIBLE DEATH. THE VEHICLE WAS TOWED TO OURISMAN CHEVROLET IN MARLOW HEIGHTS MARYLAND FOR REPAIR AFTER THE TOW TRUCK DRIVER MANUALLY SHIFTED THE TRANSMISSION INTO DRIVE FROM UNDERNEATH THE VEHICLE THAT WOULD'VE BEEN EXTREMELY DANGEROUS FOR THE TOW DRIVER TO DO IF THE VEHICLE HAD BEEN FACING DOWN HILL OR IN A HEAVY TRAFFIC SITUATION. FOR SOME REASON, HOWEVER, MY VEHICLE STILL HASN'T BEEN REPAIRED NOR HAVE I'VE BEEN GIVEN A REASON AS TO WHY.

DEAR SIR/MADAM, I HAVE A 2003 GMC ENVOY SLT MODEL 4.2L V6 4WD AND AS I WAS BACKING INTO MY GARAGE I HEARD A LOUD BANG AND WHINNING NOISE AND I NOW HAVE NO REVERSE GEAR AND WHEN I SELECT THE DRIVE GEAR ON THE AUTOMATIC TRANSMISSION I HAVE A WHINNING NOISE, I HAVE READ THE BLOGS ON THIS ISSUE AND I BELIEVE THAT GM AND GMC ARE VERY AWARE OF THIS PROBLEM, THIS REPAIR WILL COST ME UP TO $2,800.00 PLUS TAX TO HAVE THE TRANSMISSION REMOVED AND A RE-MANUFACTURED ON REPLACED ON MY VEHICLE. I WAS JUST GLAD THAT THIS MATTER HAPPENED AT MY RESIDENCE AND NOT ON SOME BACK ROAD IN WEST VA., I BELIEVE THAT AS STATED, GM AND GMC IS VERY AWARE OF THE PROBLEM WITH THE 4L603 TRANSMISSION THAT WERE USED IN THESE VEHICLES' AND THE PROBLEM WITH THE SUN-SHELL AND THE REACTION SUN...

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THAT THE VEHICLE LOST ALL POWER AFTER AN ATTEMPT WAS MADE TO SHIFT GEARS FROM DRIVE TO PARK . THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 175,000. THE CURRENT MILEAGE WAS 175,000.

THE GEAR SHIFT SELECTOR CABLE BECAME DISENGAGED FROM THE TRANSMISSION WHILE BACKING OUT OF A PARKING SPOT. ACCORDING TO MY MECHANIC, THERE IS A SMALL PLASTIC BUSHING THAT BECAME BRITTLE AND FELL OFF CAUSING THE FAILURE OF THE CABLE TO MAINTAIN A CONNECTION WITH THE TRANSMISSION. THIS CAUSED MY TRANSMISSION TO BECOME LOCKED IN THE PARK POSITION AND UNABLE TO BE MOVED INTO ANY OTHER DRIVE. WHILE I WAS IN A SAFE LOCATION, I'M CONCERNED THAT OTHER DRIVERS IN SIMILAR SITUATIONS WILL BECOME STRANDED IN LOCATIONS THAT ARE NOT SAFE. I CONDUCTED A RECALL SEARCH AND FOUND THAT THIS ITEM HAS NOT BEEN RECALLED. I PLACED A CALL TO GENERAL MOTORS AND LODGED A COMPLAINT. ACCORDING TO GM, THEY HAVE RECEIVED A NUMBER OF COMPLAINTS ABOUT THIS ISSUE BUT ARE NOT ISSUING A RECALL AT THIS TIME. I ASKED GM TO PROVIDE ME THE NUMBER OF COMPLAINTS THEY HAVE RECEIVED...

TL* THE CONTACT OWNS A 2003 GMC ENVOY. THE CONTACT STATED THE SERVICE FOUR WHEEL DRIVE LIGHT ILLUMINATED WHILE THE VEHICLE WAS PARKED. THE CONTACT STATED THAT THE FOUR WHEEL DRIVE WAS INOPERABLE WHEN THE LIGHT WAS ILLUMINATED. THE FAILURE RECURRED INTERMITTENTLY. THE DEALER WAS CONTACTED AND ADVISED THAT THE SWITCH WOULD NEED TO BE REPLACED IN ORDER TO CORRECT THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 111,000.

2003 GMC ENVOY SLE WITH 42,000 MILES. CHECK 4 WDRIVE LIGHT CAME ON THEN WENT BACK OFF. DEALER STATED THAT THE TCCM HAD TO BE REPROGRAMMED DUE TO A BULLETIN. IT COST ME OUT OF POCKET NO WARRANTIES COVER THIS. ALSO THE FAN CLUTCHES WENT OUT BUT WAS REPLACED BY EXTENDED WARRANTIES. I'M ALSO TOLD BY DEALER THAT THE STEERING LINKS ARE WORN & SHOULD BE REPLACED. THIS TOO IS AT MY COST. I HAVE ONLY HAD THIS CAR 1 YEAR. THESE HAPPENED WITH JUST A FEW WEEKS OF EACH OTHER. *TR

ELECTRONIC PROBLEM WITH 4WD WAS SUPPOSEDLY CORRECTED IN 2004, TRANSFER CASE FOR 4WD WAS REPLACED IN APRIL 2005, AND 4WD FAILED AGAIN DURING FIRST DAY TRYING TO USE IT DURING ICY CONDITIONS AFTER IT WAS "REPAIRED" IN APRIL. HAD TO DRIVE ON DANGEROUS, SLICK ROADS WITHOUT 4WD FROM FAIRBANKS TO PALMER, AK. THIS IS A MAJOR SAFETY ISSUE IN ALASKA WHERE WINTER DRIVING CAN BE VERY HAZARDOUS WITHOUT 4WD. HAVE HAD IT INTO DEALER SEVERAL TIMES FOR LOUD SQUEAK UNDER VEHICLE WHEN MAKING TURNS OR GOING OVER BUMPS AT SLOW SPEEDS. NO CORRECTIVE ACTION BY DEALER. COULD NOT GET VEHICLE OUT OF "PARK". HAD TO HAVE IT TOWED TO DEALERSHIP. THEY DISCONNECTED SOMETHING AND TOLD ME TO BE CAREFUL BECAUSE WHATEVER THEY DID WOULD ALLOW THE VEHICLE TO BE PUT INTO "DRIVE" WITHOUT HAVING BRAKES ENGAGED! HAD TO DRIVE IT THIS WAY FOR SEVERAL WEEKS UNTIL THEY GOT REPLACEMENT PART....

WITH ABOUT 1100 MILES ON MY BRAND NEW CAR , THE 4WD LIGHT CAME ON. NOT HAPPY ABOUT THIS PURCHASE. *AK
