2017 GMC Yukon Xl

THE WHOLE BACK TAIL LIGHT HAD TO BE REPLACED AFTER FAILING. POOR DESIGN AND A COMMON PROBLEM ON THE 2015-2017 GMC YUKONS. THERE IS A COMMON AREA THAT BREAKS. NOT ONLY A BIG EXPENSE BUT ALSO A LARGE WASTE OF MATERIAL CONSIDERING THE WHOLE UNIT HAS TO BE REPLACED. COST IS OVER $800.00 AND THE DEALER BUYS BACK THE OLD LIGHT FOR $50 SEEMS A BIT SUSPICIOUS BY GMC. THESE LAMPS ARE A SEALED UNIT AND WERE NEVER DESIGNED TO BE REPAIRED. AS DESIGNED, IF THERE IS A PROBLEM, THE LAMP IS REPLACED AS A COMPLETE AND VERY EXPENSIVE UNIT.

WHILE STANDING BEHIND THE VEHICLE AND ATTEMPTING TO REMOVE ITEMS FROM THE REAR CARGO AREA, THE LIFT GATE RANDOMLY SLAMS SHUT WITHOUT NOTICE OR WARNING. THIS OCCURRED SEVERAL TIMES WHILE I WAS BEHIND THE VEHICLE. ON SOME OCCASIONS MY CHILD(REN) WAS WITH ME ANDWAS ALMOST HIT AS WELL. SINCE I AM TALLER I WAS HIT AND WAS ABLE TO SAVE MY CHILD FROM INJURY. I WAS HIT SEVERAL TIMES ON DIFFERENT OCCASIONS EITHER I THE HEAD OR IN THE BACK, DEPENDING ON MY POSITION AT THE TIME. I ENSURED THAT I DID NOT HAVE THE KEY FOBIN MY POCKET TO ACCIDENTLY ACTIVATE THE CLOSURE, AND I ENSURE THAT I DID NOT ACCIDENTLY ACTIVATE THE CLOSURE SENSOR UNDERNEATH THE REAR BUMPER AREA. UPON INVESTIGATION THE DEALER DETERMINE THE CAUSE TO BE A LIFT GATE MODULE DEFECT, AS WELL AS SENSOR AND LIFTGATE CALIBRATION.
