2017 GMC YUKON Complaints

LEFT AND RIGHT BRAKING LIGHTS SOME TIME DO NOT WORK WHEN BRAKING. ONLY THE REVERSE LIGHT WILL WORK WHILE THE BRAKING LIGHT WILL NOT. TO ADD, WHEN THE FRONT HEADLIGHTS ARE ON, SOME TIMES THE LEFT AND RIGHT TAIL LIGHTS (LIGHT THAT IS ON WHEN NOT BRAKING) AND BRAKING LIGHTS WILL NOT WORK. I HAVE HAD TWO DIFFERENT PEOPLE PULL UP NEXT TO ME SAYING MY BRAKE LIGHTS ARE OUT IN THE LAST TWO WEEKS. HOWEVER, I HAVE OBSERVED WHEN THEY ARE WORKING IN THAT SAME TIME SPAN. THE LAST TWO DAYS, ONLY THE RIGHT TAIL/BRAKING LIGHT IS NOT WORK.

PASSENGER SIDE REAR LED BRAKE LIGHT HAS STOPPED WORKING. IT DOES NOT LIGHT UP.THIS IS A PROBLEM THAT HAS OCCURRED IN THE 2015 AND 2016 YUKONS. I WAS INFORMED BY A FELLOW MOTORIST THAT MY BRAKE LIGHT WAS OUT. THE REPAIR IS ESTIMATED AT $850.00 AS THE WHOLE REAR LIGHT UNIT MUST BE REPLACED.

DRIVER SIDE REAR BRAKE LIGHT ISN'T WORKING ANYMORE. 46K MILES ON A 2017 GMC YUKON.

BRAKE LIGHT FAILURE. BRAKE LIGHTS WORK INCONSISTENTLY. CHANGING THE BULB DOES NOT FIX THE PROBLEM. THIS IS AN ELECTRICAL ISSUE THAT HAS BEEN REPORTED BY NUMEROUS OWNERS. THIS IS A SAFETY HAZARD AS THE COMPONENTS HAVE TO BE REPAIRED BY A TECHNICIAN WHICH CAUSES HUNDREDS OF DOLLARS, PER LIGHT. THIS IS A DEFECTIVE PRODUCT THAT SHOULD BE RECALLED!!!

WHEN TRAVELING AT LOW SPEEDS (10-20 MPH), I HAVE CONTINUOUSLY EXPERIENCED "LUNGING" AND "JERKINESS" WITH MY TRANSMISSION FOR OVER 2 YEARS NOW. DESPITE APPROXIMATELY A DOZEN SEPARATE EVALUATIONS AND/OR REPAIRS BY GM-CERTIFIED TECHNICIANS, THE PROBLEM CONTINUES TO EXIST. I AM TOLD THAT THE ISSUE IS NORMAL AND THAT I MUST LIVE WITH THE ISSUE AS BEING NORMAL. NOT ONLY AM I CONCERNED ABOUT THE ONGOING MAINTENANCE COST, BUT THE SAFETY OF MYSELF AND PASSENGERS SHOULD THE VEHICLE STRIKE AN OBJECT OR PERSON ACCIDENTALLY. ACCORDING TO VARIOUS ONLINE SOURCES, THERE ARE HUNDREDS OF GM OWNERS WHO ARE EXPERIENCING SIMILAR ISSUES, AND EVEN A CLASS ACTION LAW SUIT HAS BEEN FILED. HOWEVER, THERE HAS BEEN NO ACKNOWLEDGEMENT OR MEANINGFUL RESOLUTION TO THE PROBLEMS.

WHILE SITTING AT A STOP ON A 9DEGREE INCLINE BEHIND ANOTHER VEHICLE I STARTED TO ACCELERATE TO MOVE UP TO THE STOP SIGN. AS I PRESSED ON THE ACCELERATOR THE ENGINE RPM'S INCREASED BUT THE VEHICLE DIDN'T MOVE AS IF THE TRANSMISSION WAS NOT ENGAGING, THEN WITHOUT WARNING IT JERKED FORWARD. I HAD TO APPLY THE BRAKES TO KEEP FROM HITTING THE VEHICLE IN FRONT OF ME. I HAVE ALSO HAD PROBLEMS WITH THIS VEHICLE TRANSMISSION SUCH AS TRANSMISSION FLUTTER, HARSH SHIFTS IN LOWER GEARS, ETC ETC.

BRAKE LIGHTS WORK INTERMITTENTLY. VERY DANGEROUS! PASSENGER SIDE BRAKE LIGHT, STOPPED WORKING COMPLETELY, THEN CAME BACK ON.

MY 2017 GMC YUKON DENALI CONTINUES TO HAVE A VERY LOUD SHUDDER SOUND AS YOU ACCELERATE.

INTERMITTENT FAILURE OF ONE BRAKE LIGHT WHILE MOVING. VEHICLE HAS ONLY 38000 MILES. THIS APPEARS TO BE A COMMON COMPLAINT (JUDGING BY CAR FORUMS). I UNDERSTAND GMC MAKES AN IMPROVED VERSION OF THIS ASSEMBLY. GIVEN THE POTENTIAL SAFETY ISSUE, THIS SHOULD BE A RECALL.

BOTH BRAKE LIGHTS STOPPED WORKING AT THE SAME TIME. THERE IS NO FUSE. ONLINE REPORTS SHOW MANY PEOPLE WITH THE SAME VERY DANGEROUS, HUGE SAFETY ISSUE OF THEIR BRAKE LIGHTS FAILING. THE CAR 3 YEARS 2 MONTHS OLD.
