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

Mileage: 67,500

REAR PASSENGER BRAKE LIGHT WORKS INTERMITTANTLY WHILE DRIVING.

AT 75,000 MILES I WOULDN'T EXPECT TO HAVE THIS MANY ISSUES OUT OF SUCH A NICE EXPENSIVE TRUCK... THE CHECK ENGINE LIGHTS COMES ON AND OFF AND IT PLEASES. WHEN THE CHECK ENGINE LIGHT IS ON THE REMOTE START DOESN'T WORK. THE TAIL LIGHTS WORK WHEN THEY WANT TO AND TO FIX A TAIL LIGHT JUST 1 IS $800.00. WHILE DRIVING ALL TYPES OF WARNINGS AND LIGHTS START COMING ON IN A RAPID WARNING ANNOYANCE. I'VE NEVER HOOKED A TRAILER TO THIS TRUCK AND IT KEEPS GIVING ME SOME TYPE OF TRAILER BRAKING SYSTEM WARNING. THE CRUISE CONTROL WORKS WHEN IT WANTS TO. BIG ISSUE!!!!! THE TRANSMISSION IS SLIPPING!!!!!!!!!!!! WHEN DRIVING IT WILL GIVE A HARD JERK AS IF IT'S HAVING TROUBLE SHIFTING. DOING THIS AT ANY SPEEDS, ANYTIME DURING ACCELERATING. SO MANY ISSUES OUT OF THIS TRUCK IT'S TO THE POINT WE ARE THROWING AWAY A TON OF MONEY ONTHIS THING!!!!!

APPROXIMATELY 51,000 MILES ON VEHICLE: REAR PASSENGER TAIL LIGHT IS INOP. WE WERE ON A TRIP WHEN WE NOTICED, IF YOU TAP THE SIDE OF IT THE LIGHT WOULD COME ON FOR JUST A SECOND. LED STRIP FOR BRAKE LIGHT IS DEFECTIVE. REPLACEMENT COST IS ABOUT $800 DOLLARS. LOTS OF COMPLAINTS AND ONLINE FORUMS REGARDING THIS ISSUE. GMC REALLY NEED TO RESOLVE THIS ISSSUE. THESE RIGS COST WAY TO MUCH FOR THAT POOR QUALITY!

LED BRAKE LIGHTS FAILED IN BOTH TAIL LAMPS. LED IS SUPPOSED TO BE A LONGER LASTING ALTERNATIVE TO STANDARD LIGHTS. UNFORTUNATELY THE WAY GM DESIGNED THESE YOU CANNOT SERVICE OR REPAIR THEM LIKE YOU CAN WITH A TRADITIONAL BULB. AFTER MUCH RESEARCH IT APPEARS THAT THERE IS A THIN STRIP THAT BREAKS IN THE CIRCUIT CAUSING BOTH TAILLAMPS TO LOOSE FUNCTIONALITY, THERE IS NO BULB OUT WARNING SO THE DRIVER IS NOT ALERTED. AND WITH NO BRAKE LAMPS THIS COULD RESULT IN A CRASH OR INJURY.

'TAKATA RECALL' WE JUST PURCHASED OUR 2015 YUKON DINALI XL DECEMBER 20, 2018 AND HAVE HAD NOTHING BUT PROBLEMS WITH BRAKE LIGHT ( WHILE IN MOTION ) ON DRIVER-SIDE WORKING INTERMITTENTLY, SO WE REPLACED BOTH TAILLIGHTS WITH BRAND NEW ($700) ENCLOSED REAR LIGHT ASSEMBLY AND NOW WE ARE HAVING AN ISSUE WITH DRIVER SIDE ONCE AGAIN. I'M VERY PROUD TO BUY AMERICAN MADE PRODUCTS BUT AFTER SEEING HOW MANY GMC MONTHLY COMPLAINTS WITH THIS SAME ISSUE, YOU WOULD THINK THAT GM WOULD STAND BEHIND THEIR PRODUCT. I KNOW MYSELF BEING IN BUSINESS IF I HAD A COMPLAINS MORE THAN THREE TIMES A MONTH I WOULD TRY MY BEST TO CORRECT THE PROBLEM TO KEEP FROM HAVING A BAD REPUTATION AND HAVE A FUTURE CUSTOMERS!! I TAKE PRIDE IN MY WORK FOR WHAT OUR CUSTOMER PAYS, AND EXPECT THE SAME FOR WHAT I PAY!!

CAR WAS PARKED IN COVERED GARAGE FOR 2 MONTHS. BATTERY WENT DEAD. ATTEMPTED TO CHARGE BATTERY WITH 20 AMP CHARGER AND BATTERY WOULD NOT TAKE A CHARGE. ATTEMPTED TO START CAR WITH BATTERY BOOSTER PACK AND LIGHTS WOULD COME ON, BUT CAR WOULD NOT START SITTING IN VEHICLE WITH KEY FOB. CONSOLE DISPLAY SAID THAT STEERING WHEEL WAS LOCKED. CALLED AAA AND THEY CAME OUT TO REPLACE BATTERY. IT WAS THE ORIGINAL BATTERY...BUT HAD WORKED PERFECTLY WHEN CAR WAS PARKED EARLIER. NEW BATTERY ALLOWED LIGHTS AND ALL OTHER FUNCTIONS TO WORK, BUT CAR WOULD STILL NOT START. I CLOSED DOORS....HOOD AND THEN WAS ABLE TO START CAR WITH KEY FOB REMOTE STARTER. CAR WORKED PERFECTLY. SHUT CAR OFF AND TRIED TO START AGAIN AND WOULD NOT START NORMALLY, BUT WOULD START FINE REMOTELY. CALLED DEALERSHIP AND THEY HAD NOT HEARD OF THIS ISSUE, AND I MADE APPOINTMENT TO BRING IN. TWO DAYS BEFORE APPOINTMENT, CAR WOULD NOT EVEN START REMOTELY. ONLY THING THAT HAPPENED WAS THAT OUTSIDE MIRRORS WOULD RETRACT WHEN I TRIED TO START REMOTELY. PAID $90 TO HAVE CAR FLATBED TOWED TO DELEARSHIP. PAID $234.99 FOR DEALERSHIP TO CLEAR ALL CODES AND REPROGRAM. HAVE CALLED GMC SEVERAL TIMES AND THEY REFUSE TO ACKNOWLEDGE PROBLEM OR REIMBURSE ME. DEALERSHIP HAD NEVER SEEN THIS ISSUE BEFORE AND TOLD ME WHEN THEY SPOKE WITH GMC TECHNICAL DEPARTMENT THAT THIS ISSUE HAD NEVER OCCURRED. I FIND THAT VERY SUSPICIOUS. HOW COULD A BAD BATTERY TRIGGER A COMPUTER TO NOT ALLOW THE CAR TO START. THIS IS A VERY DANGEROUS SITUATION BECAUSE IF I WAS STRANDED ON A HIGHWAY AND THE BATTERY WENT DEAD AND A NEW BATTERY OR JUMP START WOULD NOT ALLOW COMPUTER TO START CAR, THERE COULD BE UNFORTUNATE CONSEQUENCES. I HAVE OWNED DOZENS OF CARS WITH THEFT DETERRENT SYSTEMS AND A BAD BATTERY THAT HAS BEEN REPLACED HAS NEVER TRIGGERED THE SYSTEM TO MAKE THE VEHICLE UNABLE TO START. PLEASE ADVISE. THANKS

VEHICLE TAIL LIGHTS AND BRAKE LIGHTS QUIT WORKING. THE LED CIRCUITS BREAK CAUSING THE CONNECTION TO SHORT OUT. BOTH THE TAIL LIGHTS AND BRAKE LIGHTS DO NOT WORK ONCE THE CIRCUIT IS BROKE. THE OWNER CAN'T SIMPLY FIX THE BURNT OUT TAIL LIGHT. ONE MUST COMPLETELY REPLACE THE ENTIRE ASSEMBLY, COSTING UPWARDS OF $1,000 FOR BOTH. THIS IS NOT COST EFFECTIVE AND IS DOWNRIGHT HAZARDOUS WHEN BOTH TAIL LIGHTS GO OUT, FOR BOTH THE OWNER AND OTHER DRIVERS ON THE ROAD. THE TAIL LIGHT ASSEMBLY SHOULD BE ABLE TO RESIST ROAD BUMPS AND VIBRATIONS.

LED LIGHTS IN THE REAR ARE REPEATEDLY DEFECTIVE

2015 GMC YUKON XL HAVE A CONDITION THAT ALLOW WATER TO LEAK INTO THE VEHICLE'S ROOF-MOUNTED ANTENNA. THIS CONDITION PREVENTS THE VEHICLE'S ONSTAR SYSTEM FROM ACCURATELY DETERMINING THE VEHICLE'S LOCATION; DISABLE THE VEHICLE'S COMPASS, NAVIGATION, AND XM RADIO SYSTEMS; ILLUMINATE THE VEHICLE'S RED ONSTAR LED INDICATOR. GMC CUSTOMER SATISFACTION PROGRAM ' LOSS OF GPS, ONSTAR AND XM ANTENNA FUNCTIONS ' 2015 CADILLAC CHEVROLET GMC 15155 EXPIRED AUGUST 2017 BUT DOES NOT ADDRESS A SOLUTION FOR THE VEHICLES THAT MISSED THE DEADLINE.

JUST GOT THIS VEHICLE 2 MONTHS AGO. BRAKE LIGHTS SEEM TO WORK WHEN THE WANT TO. HAVE READ OTHERS REVIEWS AND SEEMS EVERYONE WITH THIS VEHICLE IS HAVING THE SAME ISSUE! THE CRUISE CONTROL WORKS WHEN IT WANTS TOO,. CHECK ENGINE LIGHT IS OFF AND ON HAD IT CHECKED ONCE WHILE ON AND WAS TOLD IT'S AN O2 SENSOR. WHEN THE CHECK ENGINE LIGHT IS ON REMOTE START WON'T WORK. SEEMS THE BRAKE LIGHT ISSUE IS PURPOSEFUL SINCE SO MANY PEOPLE HAVE THE SAME ISSUE AND IT COSTS SO DANG MUCH TO FIX IT! FOR SUCH A NICE VEHICLE AND EXPENSIVE PAYMENT YOU WOULD THINK THERE WOULD BE NO ISSUES.

I PUT IN ANOTHER COMPLAINT AND FORGOT TO ADD MAYBE THE MOST IMPORTANT DETAILS!!!! I HAVE NOTICED MY CRUISE CONTROL, CHECK ENGINE LIGHT, BRAKE LIGHTS, AND REMOTE START THOUGH I'M HAVING ISSUES WITH THEM ALL WORKING ONLY WHEN THEY WANT TO IT SEEMS WHEN IT'S HOT OUTSIDE ALL OF THESE THINGS GO HAY WIRE AND WHEN IT'S FREEZING COLD (COLORADO WINTER) EVERYTHING WORKS FINE. TODAY HIGH OF 40 EVERYTHING IS WORKING FINE... HIGHS IN THE 80+ EVERYTHING SEEMS TO NOT WORK. SO IT'S BASICALLY BOILING DOWN TO ELECTRICAL ISSUES WHEN IT'S HOT AND NO ISSUES WHEN IT'S FREEZING COLD. CAN SOMEONE PLEASE FIX THIS!!!! I'VE SEEN NUMEROUS COMPLAINTS OF OTHERS HAVING THE SAME ISSUES WITH HEAT AND ELECTRICAL ISSUES.(CARGURUS.COM) PLEASE SOMEONE DO SOMETHING GM NEEDS TO FIX THIS!!!!!!!! I ONLY HOPE OTHERS HAVE MADE THESE COMPLAINTS SO GM CAN BE HELD RESPONSIBLE! 800$ FOR A BRAKE LIGHT GET OUT OF HERE!!!!!!!! AND THAT'S JUST THE PRICE TO FIX THE BRAKE LIGHT WHEN IT DECIDES NOT TO WORK AND I'M NOT PAYING THAT MUCH TO FIX ONE ISSUE WHEN IT SEEMS TO BE SOMETHING WITH THIS VEHICLE AND HEAT!

TAKATA RECALL WAS PULLED OVER BECAUSE MY PASSENGER TAIL LIGHT WAS NOT WORKING. TAIL LIGHT WAS WORKING THE NEXT DAY, AND THE FOLLOWING DAY IT HAD GONE OUT AGAIN. LIGHT WOULD COME BACK ON WHEN YOU HIT IT BY HAND.

WHILE IN MOTION MY VEHICLE SHUTS COMPLETELY OFF. THIS IS IN THE MIDDLE OF TRAFFIC AT TIMES. IT DISPLAYS WARNINGS THAT STABILITRACK HAS BEEN DISABLED AND SHUITS DOWN EVERYTHING ELECTRICAL. AT SOME POINTS IT DOESNT SHUT COMPLETELY DOWN, BUT INSTEAD HESITATES AND THEN PICKS BACK UP. THIS HAPPENS IN VARIOUS SITUATIONS WHETHER IT BE ON THE HIGHWAY, TURNING, OR DRIVING CITY ROADS.
