The brake lights intermittently come on and off. Not reliable and the entire assembly has to be replaced per light in order to work. Sometimes if you hit a bump it will work for a bit then go back out. They have been removed, cleaned, but there is no way to fix them without replacing them. This is a known problem with GMC and they will not warranty or recall this issue.

This is a common issue that is not being resolved by GM. First one, now BOTH of my rear tail lights are malfunctioning due to manufacturing defects. This is a well publicized problem and I feel that GM should be responsible for continuing to ignore the issue. Replacement tail lights are approximately $750 each. There are many businesses that have sprung up solely to repair these tail lights.

Tail lights are very inconsistent of working or not working. Sometimes they work but most times they don't.

I received a letter from GMC dated December 2019 warning of brake lights intermittenly not illuminating. I have periodically checked the lights for failure over the last 3 years. On September 8, 2022, a motorist pulled beside me and informed me that my brake lights were not working. I confirmed that the lights were not working and called GMC regarding the letter I had received in 2019 and was told that a recall had not been issued and that my vehicle was outside the 6 year eligibility period. This defect is Extremely Dangerous to myself and others due to the inherent unpredicability and unreliabilty of an important safety necessity, i.e., knowing that others will see that I am stopping/slowing down. I believe that due to the intermittent nature of the failure of a highly necessary safety feature, GMC should issue a recall to repair at no cost ALL vehicles.

I have had to replace both front and rear exterior lighting in past (3). Now my rear brake light is now out. This makes 3 exterior that I’ve had to complete replace. Went out suddenly. No way to replace bulbs, dealer reports Entire assembly needs replacing at cost of almost $1000. There has to be a design flaw that every exterior lighting has gone out for so many owners and has to be REPLACED. There should be a recall on this. This model has had so many costly issues.

Brake lights - left brake light works intermittently, and often does not work. 3rd brake light (top center) has quit working. Both are issues with cracks in the circuit board, which googling has shown to be a known issue. Faulty, poorly designed or constructed parts!

Breaks are faulty, lights continue to go out in the rear after only a year after purchase. I’ve read other complaints about these issues. could be wiring or electrical issue with the breaks. Engine sounds like a plane is about to take off, has had starting problems. Overall horrible vehicle. There are a lot of problems with the vehicle, the lights are extremely dangerous as person behind would not know if I’m stopping when they fail to work and can cause a serious accident. Engine is a major concern as well.

LED Brake Lights fail due to design error typically on both side of the vehicle. I have found multiple reports of a failure on a circuit board that was poorly designed. A copper tracing is very narrow and fractures due to vibration resulting in Brake Light failure. Because the entire module must be replaced the repair costs $800-$900 per side.

Tail lights are not functioning properly. N182180270 was issued due to very common issue but no recall. The special adjustment only covers up to 72,000 miles. I now have 106,000 so not covered? Serious safety issue if brake lights are malfunctioning and GM aware of issue. If technician checking lights and they are intermittently working, then I drive away from dealer and they intermittently no longer work, that is a serious safety issue and a recall should happen. I took my vehicle in for an oil change and on the drive to have serviced I was told by my wife driving behind me that the right rear brake light wasn’t working. I asked tech to check. Technician confirmed but states left isn’t working either. Yet on drive to drop the vehicle for oil change the left was working. And we have a time stamped photo as proof(attached). I had someone tell me right rear brake light was out a couple of years ago but when I had it checked, all were on. So when are they working? When are they not working? And that is why a recall should be issued. correct a faulty design. These aren’t an easy fix of replacing a bulb. The whole unit has to be replaced at $700+ each. How many people are out there driving with these intermittent brake lights? We periodically check our lights to ensure working. But if these lights are on/off intermittently, that does very little good. Scary!

THE CONTACT OWNS A 2015 GMC YUKON XL. THE CONTACT STATED THAT WHILE DRIVING AT AN UNDISCLOSED SPEED, THE CONTACT WAS ALERTED BY HER HUSBAND WHO WAS DRIVING BEHIND THE VEHICLE, THAT THE REAR TAIL LIGHTS WERE INOPERABLE. THE CONTACT WAS ALSO ALERTED BY OTHER DRIVERS THAT THE REAR TAIL LIGHTS WERE NOT FUNCTIONING AS NEEDED. THE VEHICLE WAS TAKEN TO SIERRA BLANCA MOTOR CO.

THE TECHNICIAN ALSO INSPECTED THE LIGHTS AND STATED IN THE DIAGNOSTIC REPORT THAT ALL LIGHTS WERE WORKING AT THE TIME OF INSPECTION. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER FOR THE FAILURE HOWEVER, THE SECOND DEALER WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT THEN HAD HER FRIEND, WHO WAS A RETIRED AUTHORIZED GMC TECHNICIAN, INSPECTED THE TAILLIGHTS AND DUPLICATED THE FAILURE. THE VEHICLE WAS THEN TAKEN BACK TO SIERRA BLANCA MOTOR CO. HOWEVER, THE SERVICE ADVISOR INSPECTED THE TAIL LIGHTS BUT OFFERED NO ASSISTANCE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THEY WOULD CHECK WITH THE DEALER TO SEE IF THEY COULD ASSIST WITH THE FAILURE. THE MANUFACTURER LATER INFORMED THE CONTACT THAT THEY WOULD OFFER A 25% DISCOUNT FOR EACH LIGHT TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 61,835.

LEFT REAR LIGHT ASSEMBLY INTERMITTENT OPEN CIRCUIT. WIRING CHECKS OKAY. GOOD POWER AND GROUNDS. NOTED THAT THE LAMP HOUSING HAS EVIDENCE OF CORROSION AT THE BASE OF THE MAIN CONNECTOR. THE HOUSING IS A SEALED UNIT (NO SERVICEABLE PARTS) SO THE NATURE ASSEMBLY NEEDS TO BE REPLACED. I AM A 37+YEAR A.S.E. MASTER TECHNICIAN AND STATE OF MICHIGAN MASTER TECHNICIAN SO I AM WELL SEASONED AT PROPER AUTO/LIGHT TRUCK ELECTRICAL DIAGNOSIS. THE LIGHT WILL GO OUT WHILE SITING STILL AND/OR IN MOTION. THIS IS A SAFETY CONCERN FOR OBVIOUS REASONS.

ONE OF THE BREAK LIGHTS IS OUT. THEY HAVE MADE THE BRAKE LIGHTS IN SUCH A WAY THAT YOU CAN NO LONGER JUST REPLACE THE BULBS BUT HAVE TO REPLACE THE ENTIRE UNIT AT A COST OF $885. THERE IS A DESIGN FLAW IN THE 2015 AND 2016 MODELS THAT CAUSES THE BRAKE LIGHTS TO FAIL. GMC IS AWARE OF IT AND DID EXTEND WARRANTY COVERAGE SO THAT IF YOU ARE "LUCKY" ENOUGH TO HAVE THEM FAIL WITH LESS THAN 72,000 ON YOUR VEHICLE THEY WILL REPLACE THEM AT NO COST BUT AFTER THAT THEY WILL NOT. THEY KNOW THE PRODUCT AND IT SHOULD BE RECALLED. IT IS A SAFETY ISSUE FOR PEOPLE TO DRIVE AROUND WITHOUT BRAKE LIGHTS BECAUSE IT COSTS NEARLY $900 A PIECE TO REPLACE THEM! PERHAPS THEY SHOULDN'T HAVE TURNED WHAT USED TO BE AN CHEAP, EASY THING TO FIX ON YOUR OWN INTO A $900 REPAIR IN THE FIRST PLACE. NOW THAT THEY HAVE THEY SHOULD AT LEAST STAND BEHIND THE PRODUCT.

THE LEFT LED TAIL LIGHT WOULD GO OUT AND THEN COME BACK ON. THIS HAS BEEN HAPPENING FOR OVER A YEAR NOW. POLICE STOPPED ME TWICE BUT THANKFULLY, DID NOT GIVE ME A TICKET. HAD IT REPAIRED 2 OR 3 TIMES. IT MIGHT LAST A DAY OR TWO AND THEN GOES OUT AGAIN. APPARENTLY, THERE IS A THIN METAL PIECE THAT IS SORTED TOGETHER THAT KEEPS BREAKING. THE RIGHT ONE HAS STARTED DOING IT TOO. I WAS OVER THE MILEAGE FOR THE RECALL. CAN'T AFFORD THE $1600 OR SO IT WOULD COST FOR NEW IMPROVED TAIL LIGHTS. WHAT DOES MILEAGE HAVE TO DO WITH REPAIRING A DEFECT IN THE PRODUCTS USED IN THE TAIL LIGHT? I AM CONSTANTLY AFRAID SOMEONE WILL REAR END ME SINCE THE LIGHT DOESN'T WORK.

TOOK MY CERTIFIED PRE-OWNED 2015 YUKON XL INTO DEALER WHILE STILL UNDER WARRANTY WITH INTERMITTENT FAILURE IN BOTH TAIL LAMPS (THE RED PART FOR BRAKE AND TAIL LAMP FUNCTION GOES OUT; TURN SIGNAL STILL WORKS). CONDITION WAS NOT NOTED ON MY SERVICE TICKET SINCE THE TAIL LAMPS WAS WORKING FINE AT THE TIME. WARRANTY EXPIRED, PASSENGER TAIL LAMP WENT OUT COMPLETELY AND BOTH DEALER AND A CALL TO GMC TOLD ME THAT THEY WOULDN'T ASSIST IN SPITE OF MY ATTEMPT TO ADDRESS WHILE UNDER WARRANTY. NEEDED TAIL LAMP TO PASS STATE INSPECTION AND RETURN MY WIFE AND FOUR KIDS SAFELY TO THE ROAD, SO I HAD TO PAY. AS I WALKED OUT OF THE DEALERSHIP TO RETRIEVE MY VEHICLE AFTER THE $400 PASSENGER TAIL LAMP REPLACEMENT, I FOUND THE DRIVER SIDE TAIL LAMP TO BE INOPERABLE, EVEN THOUGH IT HAD JUST PASSED THE STATE INSPECTION 20 MIN PRIOR. I SHOWED THE SERVICE ADVISOR AND SPOKE TO SERVICE MANAGER. THEY BOTH AGREED THAT THE TAIL LAMP ISSUE IS WIDE-SPREAD, UNSAFE, AND A MAJOR QUALITY ISSUE, BUT THEY WERE BOUND BY GMC POLICIES. YES, GMC EXTENDED THE WARRANTY FOR THESE TAIL LAMPS, BUT I BOUGHT MY VEHICLE AS PREOWNED CERTIFIED WITH 68K MILES. SPECIAL PART WARRANTY WENT TO 70K AND MY CERTIFIED WARRANTY WENT TO 80K. I DID MY PART AND TOOK THE VEHICLE IN AS SOON AS THE PROBLEM AROSE, YET HERE I AM HOLDING AN $800 BAG OF BROKEN TAIL LAMPS. HORRENDOUS QUALITY ISSUE THAT IS A MAJOR SAFETY ISSUE FOR THESE VEHICLES. IT IS TIME TO ISSUE THE RECALL!!!

MAJOR SAFETY ISSUES WITH THIS VEHICLE. ANOTHER 2015 YUKON WITH NO TAIL OR STOP LIGHTS. I'M OVER MILLAGE ON SPECIAL RECALL. THERE SHOULD BE NO TIME/MILLAGE ISSUE ON THIS. SEAT BELTS LOCK UP. BRAKES ARE EITHER GOOD OR MUSSY WHENEVER THEY WANT TO BE. HARD TO STOP THE VEHICLE. ALSO WHEN I FIRST PURCHASED THE VEHICLE IT WOULD COMPLETELY DIE (NO LIGHTS MOTOR DIED, NO POWER STEERING, NO AIR BAGS, NO RADIO NOTHING AT ALL ON THE X-WAY AT 70 MPH) AND THE DEALER COULD NOT REPAIR IT! RUST ON FRAME RAILS. (AND MORE).
