THE PASSENGER SIDE TAILLIGHT STARTED 'GOING OUT' RIGHT AFTER THE WARRANTY EXPIRED-MEANING, IT WOULD WORK OFF AND ON AT VARIOUS TIMES. THEN THE DRIVERS SIDE TAILLIGHT HAS STARTED DOING THE SAME THING. THIS IS A KNOWN ISSUE WITH THE GMC TAILLIGHTS AND YET GMC HAS YET TO RECOGNIZE ANY ISSUE. THIS IS A MAJOR SAFETY ISSUE FOR ANYONE DRIVING THESE MODELS WITH FAILING TAILLIGHTS. THIS NEEDS TO BE INVESTIGATED

THE WHEELS HAVE CORROSION AND SHARP EDGES HAVE STARTED TO FORM. THESE SHARP EDGES ARE PUTTING PRESSURE ON THE THE TIRES CAUSING THEM TO LOSE AIR. WE WERE REQUIRED TO PURCHASE NEW WHEELS AS THE ONLY SOLUTION. WHEELS SHOULD LAST THE LIFE OF A VEHICLE, NOT FOUR YEARS.

MY YUKON MAKES VERY HARD SHIFTS WHEN ACCELERATING AND DECELERATING. THE TCM WAS REPROGRAMMED AFTER VEHICLE SHUT OFF ON THE HIGH WAY LAST NOVEMBER. NOW THE TRUCK SHUDDERS BETWEEN 25 AND 45MPH ESPECIALLY WHEN CLIMBING OR FILLED WITH PASSENGERS. VIBRATION CAN BE FELT THROUGH THE CABIN.

FAULTY BRAKE-LIGHT AND COSTLY FIX. DEALERSHIP HAS TAILLIGHT ON BACK ORDER SO A REPLACEMENT ISNT EVEN AVAILABLE. DEALERSHIP WANTS $675 JUST FOR THE PART THAT CANT EVEN BE ORDERED. DANGEROUS TO DRIVE THE VEHICLE WITH NO SOLUTION AVAILABLE.

TAIL LIGHTS INTERMITTENTLY GO OUT WITHOUT NOTICE. THIS CAN HAPPEN WHILE DRIVING OR STATIONARY

WE HAVE HAD BOTH OUR TAILLIGHTS FAIL. THE BLINKERS STILL FUNCTION BUT BECAUSE THEY ARE LED THEY SAY THEY MUST REPLACE THE WHOLE UNIT. EACH SIDE COST $672. THAT IS OUTRAGEOUS FOR A TAILLIGHT. THERE NEEDS TO BE A WAY TO REPLACE EACH PIECE.

VEHICLE HAS UNDER 45,000 MILES AND BOTH HEADLIGHTS NEED TO BE REPLACED DUE TO MALFUNCTIONING LED'S FROM WATER INTRUSION. THIS HAPPENS AFTER WASHING MY CAR AND NOW IT WILL NOT PASS STATE INSPECTION DUE TO DRIVER SIDE DAYTIME LED NOT TURNING ON, AND PASSENGER SIDE DRL NOT TURNING OFF. I CAN NOT GET THIS FIXED BECAUSE THE PASSENGER SIDE LIGHT IS ON BACKORDER, YET MY LOCAL DEALER SAID THIS ISN'T A KNOWN PROBLEM. TAKE A LOOK ON THE INTERNET AND IT'S CLEARLY A MANUFACTURING ISSUE (HENCE BACKORDERED HEADLIGHTS)
