2015 YUKON XL PASSENGER SIDE BRAKE LIGHTS DON'T WORK

NHTSA ODI 11060826

VEHICLE WAS MANUFACTURED MID 2014, 2015 MODEL, CURRENTLY HAS JUST OVER 52K MILES. DRIVERS SIDE TAILLIGHT IS BEING TEMPERAMENTAL; NO WARNING LIGHTS INSIDE TO INDICATE A FAILURE. WHEN YOU PRESS ON THE TAILLIGHT IT STILL ILLUMINATES, THERE ARE NO LEDS OUT, BUT TAILLIGHT AND BRAKE LIGHT WON'T ILLUMINATE. CALLED THE DEALERSHIP AND THEY'VE STATED IF FOUND FAULTY IT REQUIRES COMPLETE REPLACEMENT OF THE TAILLIGHT AND IT WAS QUOTED AT ROUGHLY $850 INSTALLED, WHICH SEEMS REALLY EXCESSIVE WHEN A TAILLIGHT GOES OUT.

THE PASSENGER SIDE HEADLIGHT ASSEMBLY WAS WORKING AND NOW AFTER HAVING THE TRUCK SINCE APRIL THE RUNNING LIGHT HAS GONE OUT COMPLETELY. IT WAS ALREADY HARD SEEING THE ROAD AHEAD WITH THE LIGHTS WORKING BECAUSE ALL OF THEM ARE SO DIM BUT NOW IT IS EVEN WORSE. THE ENTIRE HEADLIGHT HAS TO BE REPLACED BECAUSE OF MOISTURE INSIDE THE SO CALLED SEALED ASSEMBLY. I TOOK THE TRUCK TO THE DEALERSHIP ONLY TO FIND OUT THAT IT WILL COST ME $1200 PLUS DOLLARS FOR THE LIGHT AND LABOR THIS IS REALLY RIDICULOUS. I HAVE READ ON MANY DIFFERENT GMC FORUMS THAT THIS IS AN ALL AROUND STATE TO STATE PROBLEM THAT I THINK GMC SHOULD ADDRESS NOT ONLY BECAUSE OF THE COST BUT BECAUSE OF THE SAFETY ISSUES THAT THIS POSES. PLEASE DO SOMETHING ABOUT THIS PROBLEM.

THE BRAKE LIGHTS IN THIS VEHICLE ARE FAULTY. MY DRIVER SIDE WENT OUT IN JULY AND IN THE SAME MONTH MY PASSENGER SIDE WENT OUT. THE BULBS ARE NOT BURNED OUT AND IT HAS TO DO WITH THE WIRING. GMC WILL NOT COVER THE SECOND LIGHT OR PROVIDE COST ASSISTANCE BECAUSE I AM OUT OF WARRANTY DUE TO MILES.

WATER/CONDENSATION IN HEADLAMP, NO INDICATION OF CRACKS, TURN SIGNAL AND PORTION OF HEADLIGHT IS NOW MALFUNCTIONING. THIS IS A CONSTANT PROBLEM.

NHTSA ODI 11014109

I HAVE A 2015 GMC YUKON WITH CONDENSATION IN THE RIGHT AND LEFT FRONT HEADLIGHT ASSEMBLIES. MY TURN INDICATOR STOPPED WORKING WHICH USUALLY INDICATES A BURNED OUT BULB. I DID NOT NOTICE THE CONDENSATION AND I TOOK MY YUKON TO THE DEALERSHIP FOR WHAT I THOUGHT WAS GOING TO BE A SIMPLE BULB REPLACEMENT. THE HEADLIGHT ASSEMBLIES ARE COMPLETELY SEALED WHICH REQUIRES THE REPLACEMENT OF THE COMPLETE LAMP ASSEMBLY IF A BULB FILAMENT BURNS OUT. THE DEALERSHIP POINTED OUT THE CONDENSATION AND TOLD ME THE BULB MALFUNCTION IS LIKELY CAUSED BY THE CONDENSATION. SINCE MY VISIT TO THE DEALERSHIP YESTERDAY, THE TURN INDICATOR HAS WORKED INTERMITTENTLY. A CALL BACK TO THE DEALERSHIP WITH THE UPDATE AND THE RESPONSE WAS THAT THE CONDENSATION LIKELY CAUSED CORROSION AND STILL NEEDED TO BE REPLACED. THEY ADVISED ME THE OTHER HEADLIGHT AND SIGNAL INDICATOR WERE LIKELY TO MALFUNCTION AS WELL. IT IS OBVIOUSLY AN ONGOING ISSUE SINCE GM ISSUED A TECHNICAL SERVICE BULLETIN AROUND MAY 2014 AND UPDATED IT IN MARCH 2016 TO INCLUDE 2016 AND 2017 MODELS. THE CONDENSATION COVERS THE ENTIRE LENS. THIS IS OBVIOUSLY AN ISSUE AT NIGHT WHEN USING THE HEADLIGHTS. THE HEADLIGHT ASSEMBLY IS NON SERVICEABLE - ENTIRE HEADLIGHT ASSEMBLY MUST BE REPLACED FOR NON-WORKING BULB AT A HUGE COST $1200/SIDE). GMS TECHNICAL SERVICE BULLETIN NOTES THAT IF CERTAIN CONDITIONS ARE NOTED (SUCH AS IN MY CASE), THE REPLACEMENT OF THE LAMP ASSEMBLY MAY NOT CORRECT THIS CONDITION.

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING 60 MPH, THE EXTERIOR DOOR APPLIQUE COVERS RATTLED VIOLENTLY. THE CONTACT WAS INFORMED TO CONTACT THE MANUFACTURER TO REPORT A NON-SAFETY RELATED DEFECT. THE CONTACT ALSO STATED THAT THE REAR PASSENGER SIDE BRAKE LIGHT FAILED INTERMITTENTLY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 40,600.

REAR TAILLIGHTS HAVE MOISTURE IN THEM. THE MOISTURE IS CONSTANT IN ONE AND INTERMITTENT IN THE OTHER. BOTH HAVE BEEN REPLACED ONCE BY DEALER 3 MONTHS AGO. PROBLEM STILL EXISTS

NHTSA ODI 10978631

TL* THE CONTACT OWNS A 2015 GMC YUKON. WHILE DRIVING VARIOUS SPEEDS, THE BRAKE LIGHTS FAILED TO ILLUMINATE WHEN THE BRAKE PEDAL WAS DEPRESSED. THE DEALER DIAGNOSED THAT THE TAIL ASSEMBLY NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 35,510.

NHTSA ODI 10960379

HEADLIGHTS DO NOT ILLUMINATE THE ROAD FAR ENOUGH TO ALLOW SAFE DRIVING. TOOK VEHICLE TO LOCAL DEALER AND THEY CHECKED THE LIGHTS AND SAID THEY MEET MANUFACTURES SPECIFICATION. WHEN DRIVING ON COUNTRY ROAD WITH NO OTHER ILLUMINATION THE HEADLIGHTS DO NOT PROJECT FAR ENOUGH TO SEE WHAT IS AHEAD. DRIVING AT POSTED SPEEDS 55 TO 60 MPH CANNOT SEE WHAT IS COMING UP. HAVE TO USE HIGH BEAM IN ORDER TO SEE FAR ENOUGH TO BE SAFE. DID AN ONLINE SEARCH AND FOUND THAT THIS IS A COMMON COMPLAINT FOR THIS MODEL YEAR. *TR

I WOULD LIKE TO RESORT HOW HARD IT IS TO TELL IF THESE VEHICLES ARE TURNING OR BRAKING DUE TO THE "BRAKE-LIGHT-TURN-SIGNAL COMBINATION" WHERE THE BRAKE LIGHT GOES OFF WHEN THE TURN SIGNAL IS ON.

TRANSFER CASE ENGAGED INTO 4WD WHILE DRIVING WITH TOUCHING ANY OF THE CONTROLS. NOW IT WON'T SWITCH OUT. SERVICE 4WD LIGHT APPEARS. *TR
