TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI. WHILE REVERSING THE VEHICLE, THE CONTACT WAS INFORMED THAT THE BRAKE LIGHTS WERE NOT ILLUMINATING. HOWEVER, WHEN THE VEHICLE WAS IN DRIVE, THE BRAKE LIGHTS ILLUMINATED. ALSO, WHEN THE CONTACT DEPRESSED THE BRAKE PEDAL TO SLOW OR STOP THE VEHICLE, THE…
TAIL LIGHT CIRCUIT (LED INTERNAL TO HOUSING) CRACKS, CAUSING RAIL/BRAKE LIGHT OUTAGE WITH NO WARNINGS ON THE DASH FOR THE DRIVER. THIS IS A MATERIAL DEFECT IN THE METAL STAMPING USED FOR THE LED POWER CIRCUIT. EXACERBATED BY HEAT AND VIBRATION.
THE PASSENGER SIDE BRAKE/TAIL LIGHTS INTERMITTENTLY DO NOT WORK. THEY WORK ABOUT 60 PERCENT OF THE TIME AND THE OTHER 40 PERCENT THEY DO NOT. I HAVE READ MANY COMPLAINTS ONLINE ABOUT THIS ISSUE AND GM NEEDS TO STEP UP AND GET IT FIXED. IT IS A SAFETY ISSUE.
