2002 GMC DENALI Complaints

AT 34,000 MILES IT STARTED WITH A SQUEAKING NOISE UNDER THE TRUCK WHEN MOVING. DEALERSHIP COULD NOT FIND A PROBLEM. NOISE CONTINUED. INDIVIDUAL FOUND THAT THE "PLASTIC PARTS" USED IN THE UNIVERSAL JOINT WERE BROKEN UP INSIDE. REPLACEMENT PARTS CONSISTED OF THE SAME PLASTIC PARTS WHICH ARE IN NEED OF REPLACEMENT NOW AT 62,000 MILES. SERVICE DEPARTMENTS ARE NOT FULLY KNOWLEDGEABLE OF THE DENAHLI SYSTEM OR ITS PARTS AND SPEND MORE TIME ORDERING THE WRONG PARTS. ALSO THE ENGINE HAS CUT OUT ON ME WHILE DRIVING. LUCKLY I WAS TRAVELING AT LESS THAN 15 MILES AN HOUR. ON TOP OF EVERYTHING ELSE TODAY THE MUFFLER HAS A HOLE, THE SIZE OF A NICKLE, RUSTED OUT OF IT AND CONDENSATION WATER SHOOTING EVERYWHERE. THIS TRUCK HAS BEEN NOTHING BUT TROUBLE. HIGH PRICED TRUCK, LOW QUALITY PARTS. REPAIRS ARE IN THE PROCESS. *AK

BOTH REAR TAILGATE STRAPS SNAPPED. DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. *AK

UPON FIRST START-UP IN THE MORNING THE ENGINE TAPS FOR 10 TO15 SECONDS. THE LENGTH OF TIME AND NOISE LEVEL INCREASES WHEN THE VEHICLE SITS FOR TWO DAYS. IT IS PARKED ON LEVEL GROUND AND THE OIL LEVEL IS GOOD. IT SOUNDS TO ME LIKE A LIFTER IS LEAKING DOWN. SHORTLY AFTER VEHICLE WAS PURCHASED, IT WAS BROUGHT BACK BECAUSE OF AN OIL LEAK. THE DEALER SERVICE DEPARTMENT DISC THAT THE FRONT DIFFERENTIAL CONNECTOR ON THE LEFT SIDE WAS WHERE THE OIL WAS ORIGINATING FROM AND CORRECTED THE LOOSE VENT CONNECTOR. THE DEALER SERVICE INVOICE DOESN'T STATE HOW MUCH FLUID WAS ADDED IF ANY. SERVICE ADVISOR DID NOT KNOW THE ANSWER. *LA

CONSUMER CALLED COMPLAINING ABOUT HAVING PROBLEMS WITH ENGINE OVERHEATING. DEALER WAS CONTACTED, AND STATED THAT IT WAS NORMAL. THIS HAS OCCURRED OVER FIVE TIMES. OVERHEATING UP TO OVER THE RED SIGN OF OVERHEATING. MANUFACTURER WAS CONTACTED, AND STATED THAT THEY WON'T DO ANYTHING.*AK

THE VEHICLE WAS INVOLVED IN A FRONTAL COLLISION, AND THE AIR BAGS DID NOT DEPLOY.*JB

ENGINE TAPS LOUDLY UPON STARTUP. THIS METALLIC TAPPING OCCURS AFTER OVERNIGHT PARKING AND ALSO IF SITTING FOR AN HOUR OR SO. WHEN DRIVING COLD ENGINE, VALVE CLATTER OCCURS BEFORE EACH SHIFT OF THE AUTOMATIC TRANSMISSION. EMAIL AND TELEPHONE CORRESPONDENCE WITH GM LEFT ME WITH THEIR OFFER TO PROVIDE EXTENDED WARRANTY ON ENGINE, OF WHICH I DECLINED.

WHILE DRIVING ENGINE CHECK LIGHT KEPT COMING ON, HAD VEHICLE CHECKED SEREVAL TIMES. DEALER FINALLY FOUND THAT WATER PUMP HAD BUSTED. *AK

CONSUMER HAD TO HIT BRAKES SUDDENLY. REAR SEAT BELTS WERE INOPERATIVE. DIDN'T HOLD CHILD IN PLACE, CHILD LAUNCHED FORWARD, AS A RESULT OF SEATBELT LOOSENING UP INSTEAD OF TIGHTENING. *AK

PASSENGER SEAT BELT LOCKS TIGHT AGAINST PASSENGER--YOU HAVE TO UNBUCKLE THE SEAT BELT IN ORDER TO MOVE FOR WHATEVER REASON

WHILE DRIVING UP AND DOWN A SMALL HILL, VEHICLE SWAYS AND STEERING SEEMS LOOSE, ALMOST CAUSING LOSS OF CONTROL, DEALER NOTIFIED.*AK *TT
