PEOPLE KEPT TELLING ME ONE OF MY TAIL LIGHT WAS OUT BUT EVERY TIME I'D GET HOME MY TAIL LIGHT WAS ON! THIS KEPT GOING ON FOR A FEW WEEKS UNTIL THIS TIME I CHECKED AND IT WAS OFF. I WENT TO HAVE MY OIL CHANGED AND MENTIONED THE ISSUE. THEY DIDN'T SEE A PROBLEM BECAUSE OF COURSE IT WAS BACK ON. ABOUT A MONTH LATER, THE SAME CYCLE STARTED. MY FRIEND NOTICED THAT WHEN I WENT OVER A BUMP IT WOULD FLICK BACK ON. WE TOOK IT TO THE LOCAL GMC DEALERSHIP THAT INFORMED ME IT WAS A COMMON ISSUE IN THESE VEHICLES AND THE COST TO REPLACE WAS ABOUT $1,000. ACCORDING TO THE DEALERSHIP THE ONLY OPTION WAS TO REPLACE AND NOT FIX. I DECIDED TO LOOK UP AN ALTERNATIVE AND FOUND OUT MANY OTHERS WERE EXPERIENCING THE SAME ISSUES WITH YUKONS RANGING 2-3 YEARS AS MY VEHICLE. AFTER HAVING IT REPAIRED FOR A FRACTION OF THE COST OUTSIDE OF THE DEALERSHIP A MONTH AGO IT'S BACK TO NOT WORKING AGAIN! FRUSTRATING PART IS THAT THIS IS HAPPENING TO SO MANY OTHERS... ON YOUTUBE ALONE THERE ARE SO MANY VIDEOS SHOWING HOW TO REPAIR ON OWN BECAUSE IT'S VERY COSTLY. RECENTLY, I WAS DRIVING AND NOTICED THE PERSON IN FRONT OF ME HAD THE SAME VEHICLE AND THEIR LIGHT WAS OUT AS WELL. I GUESS I'M GOING TO HAVE TO REPLACE IT.

AT LESS THAN 3 YEARS OLD AND 60K MILES, THE FOLLOWING HAS OCCURRED AT DIFFERENT TIMES UP UNTIL NOW: OVERALL ELECTRICAL MALFUNCTION INCLUDING DISPLAY ILLUMINATION FAILURE (DISPLAY GOES COMPLETELY BLACK AND/OR DIM WHILE DRIVING - CANNOT SEE SPEEDOMETER ETC. THIS HAS HAPPENED MULTIPLE TIMES WHILE DRIVING ON BOTH THE HIGHWAY AND SURFACE STREETS, INCLUDING DAYTIME AND NIGHTTIME), AUDIO/ENTERTAINMENT SYSTEM GLITCHES (RADIO VOLUME CHANGES TO AND GETS STUCK RANDOMLY ON HIGHEST VOLUME SETTING (WAS NEVER EVEN SET TO THIS LEVEL) WHILE DRIVING, CAUSING SUDDEN DISTRACTION/DISRUPTION), TAIL LIGHT MALFUNCTION (INTERMITTENTLY STOPS WORKING BOTH LEFT AND RIGHT SIDES), AND NOW THE MOTOR TO THE SUNROOF HAS DIED (OCCURRED WHILE DRIVING AND AT A MOMENT WHEN IT WAS NECESSARY TO CLOSE FOR SAFETY ON THE HIGHWAY.) THE TRANSMISSION IS DEFECTIVE (FOR THE SECOND TIME - OFF SHIFTS AND DOWNSHIFTS UNEXPECTEDLY WHILE DRIVING AT BOTH LOWER AND HIGHER SPEEDS. HAS HAPPENED ON THE HIGHWAY REQUIRING ME TO PULL OVER AND RESTART THE VEHICLE.) THESE INCIDENTS HAVE BEEN OCCURRING FOR THE PAST SEVERAL MONTHS, BUT BECAUSE THEY HAVE BEEN INTERMITTENT IT HAS BEEN HARD TO PINPOINT WHEN TO BRING IN TO THE DEALERSHIP FOR INSPECTION.

I HAVE ONLY OWNED THIS CAR SINCE 3/29/19 AND SEVERAL TIMES NOW MY YUKON'S CHECK ENGINE LIGHT HAS CAME ON AFTER THE TRANSMISSION BUCKS, JUMPS OR JERKS HARD, NOT SURE WHAT TO CALL IT BUT IT BUCKED OR SHOVED MY CAR FORWARD WHEN TRYING TO SLOW DOWN OR STOP (NOT PRESSING GAS PEDAL). THIS COULD BE DANGEROUS AS IT INTERFERES WITH TRYING TO STOP THE VEHICLE. IT WAS SUCH A HARD JOLT THAT IT FOR A MINUTE I THOUGHT ANOTHER CAR REAR ENDED ME. THIS HAS HAPPENED AT LEAST TWICE AFTER I PRESSED THE BRAKE TO BEGIN SLOWING DOWN AS I WAS PREPARING TO PULL INTO A PARKING LOT, I WAS PROBABLY GOING AROUND 20MPH. IT ALSO HAPPENED TWICE WHILE ACCELERATING ONTO A ROAD, PROBABLY GOING 35 MPH AND JUST FELT A JOLT LIKE SOMETHING KICKED MY CAR FORWARD SUDDENLY. I'VE BEEN TOLD THAT THE JERKING PROBLEM IS RELATED TO ISSUES WITH THE TRANSMISSION, POSSIBLY THE TORQUE CONVERTER AND CAUSES GEARS NOT TO FUNCTION PROPERLY. I'M GOING TO PUT IN MY MOST RECENT DATE THAT THIS HAPPENED ON YOUR FORM BUT IT'S HAPPENED MORE THAN ONCE.

BRAKE LIGHTS OUT. !! FIRST WAS DRIVER SIDE NOW BOTH SIDES !! DEALERSHIP SAYS MODULES NEED TO BE REPLACED AND NO LONG HAVE WARRANTY COVERAGE . IT WAS 3 YR /30,00 !! I'M JUST 38,000 AND JUST PAST 3 YRS !! ABSOLUTELY RIDICULOUS $1,500.00 FOR EACH SIDES JUST FOR THE PARTS !! UNBELIEVABLE!! THAT'S NOT INCLUDED TIME AND LABOR. !! SO VERY ANGRY!! NO RECALL ON THIS BUT IN MY FINDING, I AM HEARING THIS IS AN ON GOING PROBLEM.

TAILLIGHTS, BRAKELIGHTS WORK INCONSISTENTLY. NOTHING IS WRONG WITH THE BULBS. IT IS THE ASSEMBLY AND DESIGN. IT WILL COST ABOUT 1200-2000 DOLLARS. VEHICLE BARELY HAS 32000 MILES ON IT. THIS CAN LEAD TO AN ACCIDENT.

LED BRAKE LIGHT ON DRIVER SIDE JUST STOPPED WORKING. NO DAMAGE DONE TO THE EXTERIOR.

MY PASSENGER TAILLIGHT HAS GONE OUT. THE GMC DEALER HAS SAID THEY HAVE HAD THREE INSTANCES THIS WEEK ALONE. THEY CAN REPAIR IT AND MUST BE REPLACED THE TAILLIGHTS ARE DEFECTIVE AND NEED TO BE RECALLED.
