Open the full vehicle complaint log (all categories)Rear tail lights go out intermittently caused by a defect in the vehicle manufacturer’s process in which the circuit board is broken in certain areas.
Both tail lights fail. I just bought this vehicle at Ewald Automotive in Oconmowoc Wi a month ago with 100k and I know they were aware of the problem and so is GMC. I am not paying 900 bucks for each tail light. They are absolute junk. The left side someone already messed with it because there is electrical tape on it. Ewald laughed in my face.
The taillights started to randomly go in and out. The driver side taillight stopped working but the passenger side taillight still worked. Then a day later the driver side taillight worked, but the passenger side taillight didn’t work. The next day we were going to look into this issue, and the driver and passenger side taillights were working, so we halted. We kept an eye on it and they seemed to continue to work for a few days with no issues, so drove it 20 miles to work. When I left work it was dark and I had a coworker check my brake lights before leaving and the running lights and brake lights were indeed working. By the time I arrived at home, I had no running or brake lights. This is and was a danger to others and myself as this could’ve caused an accident driving and the taillights going out. The truck did not give a warning message that I had no taillights.
Both tail lights have stopped working. I purchased in 2019 with 60k miles and by the time the first tail light failed, I was over the 72k limit. If these lights failing was an issue before, it still is an issue and the special warranty should be extended to ensure replacement of faulty items.
Numerous reports of taillights and headlights not working properly and no recall like it should be
Rear passenger running lights just stopped working. I have seen several people with the same issue. I think there should be a recall for GM to fix the issue they are clearly aware of.
My taillight has blown and I read online that several other vehicles like mines had this problem. The bulb itself can not be replaced. The whole LED box need to be replaced and one side onlybis roughly $800. Being a single mom of 3 boys, how can I afford that? I need my car inspected but with this issue I dnt know what to do. Please help.
LED brake light wiring comes undone causing brake lights to go out.
Driver Rear brake led light not working
Right brake light and tail light quit working for a few days, then returned to normal operation, both worked fine for a week then the left side went out and also returns for a few days. Now both are out except for one led per side per cluster. No brake lights except for the one over the gate. And turn signals work as they should.
Tail Lights don't work. Have seen several complaints about this problem. There is currently a lawsuit concerning this. GMC will only cover replacement if car has less than 72,000 miles. The replacement lights cost about $800 each. Having it looked at now. Fear that I will have to pay replacement costs.
STOP AND TAIL FUNCTIONS INSIDE THE TAIL LAMPS HAVE BECOME INOPERATIVE. PURCHASED VEHICLE USED AND FALLS JUST OUTSIDE OF THE SPECIAL COVERAGE ADJUSTMENT; N182180270. THIS IS STILL VERY MUCH A SAFETY ISSUE, EVEN THOUGH IT'S 1 MONTH LONGER THAN THE 6 YEAR CUTOFF.
REAR BREAK LIGHT . INTERNAL WIRING OF THE TAIL LIGHTS CRACKS LEADING TO TAIL LIGHT FAILURE. THE FAILURE DOES NOT TRIGGER ANY WARNINGS AND THE DRIVER IS UNAWARE OF THIS FAILURE UNLESS THEY PREFORM A PRE TRIP INSPECTION.

THE FAILURE MILEAGE WAS 79,800.
BOTH REAR TAIL LIGHT ASSEMBLIES WENT BAD. THE LEFT ONE IN APRIL OF 2019 AND THE RIGHT ONE IN JANUARY OF 2021. SERVICE ADVISORS IN THE 2 DEALERSHIPS I DEAL WITH CLAIM THE DO NOT KNOW ANYTHING ABOUT IT. YET A NUMBER OF REPAIR SHOPS ON THE INTERNET KNOW OF THIS PROBLEM IN 2015 TO 2019 YUKON'S BECAUSE THEY REPAIR THEM. FUNNY THAT GM DOES NOT. I SENT THE 1ST ONE OUT AND IT WAS REPAIRED FOR WELL UNDER THE COST OF A NEW ONE. I COMPLAINED AGAIN TO THE SERVICE ADVISOR ABOUT THIS ONE TO NO AVAIL. GOING TO SEND IT OUT FOR REPAIR AS WELL. INCIDENTALLY THEY COVER THE REPAIR WITH A LIFETIME WARRANTY.
Tail lights keep going out and have been replaced
MY PASSENGER BRAKE LIGHTS STOPPED WORKING. APPARENTLY THE ONLY WAY TO FIX IS TO BUY A WHOLE NEW UNIT WHICH COSTS $300-$500.
PASSENGER REAR BRAKE LIGHTS QUIT WORKING. APPEARS TO BE A DEFECT IN THE DESIGN THAT CAUSES A BREAK IN THE CIRCUIT ON THE LIGHT ASSEMBLY. REPAIR CAN BE MANUALLY DOWN BY CUTTING THROUGH PLASTIC OF ASSEMBLY AND SOLDERING BREAK, OR REPLACEMENT OF ENTIRE LIGHT ASSEMBLY. NO ACCIDENTS - JUST NORMAL DRIVING.
DRIVER TAIL LIGHT WORKS INCONSISTENTLY
THIS 2015 YUKON SLT HAS 2 FAILED REAR TAILLIGHTS AND BRAKE LIGHTS. THERE IS NO INDICATION OF THIS FAILURE IN THE INSTRUMENT PANEL. MY WIFE WAS ADVISED BY TEXT FROM A FRIEND THESE LIGHTS WERE OUT. THE REPLACEMENT ASSEMBLY IS APPX $500.00 PER SIDE PLUS INSTALLATION. I WAS ADVISED THIS IS NOT A WARRANTY ITEM AND IT IS ALSO A COMMON FAILURE ON THESE VEHICLES. NOT SURE WHEN THE FAILURE OCCURRED. THE 3RD RAISED LIGHT WAS OPERATIONAL WHEN THE BRAKES WERE USED. FIRST NOTICED AROUND JULY 10, 2020. I HAVE SEVERAL CARS FROM 2002 ON WHICH WARN OF A LIGHT FAILURE. THESE LED LIGHTS WERE ADVERTISED TO LAST FOR EXTENDED PERIODS. THIS ISSUE IS DANGEROUS AND UACCEPTABLE.
