THIS VEHICLE BREAKS FAILED ON ME WHILE DRIVING A VERY KNOWN ISSUE ON PREVIOUS YEAR

THIS IS ABOUT A 2017 YUKON XL BREAK FAILING TO OPERATE THE PREVIOUS 2016 YUKON MODELS HAVE THE SAME ISSUE AND HAVE A RECALL BULLETIN NO: PIT5361B AND THE DEALER DOES NOT WANT TO ADDRESS OR ACKNOWLEDGE THE PROBLEM

THE TRANSMISSION OR TORQUE CONVERTER ARE SHUDDERING HOW DO WE FIX, HOW DO I PROTECT FAMILY, WILL THE TRANSMISSION FALL OUT ON HIGHWAY CAN I KEEP DRIVING AND BE SAFETY WITH FAMILY?

MY HUSBAND AND I WERE DRIVING ON THE HIGHWAY AT 70 MPH WHEN HE NEEDED TO SLOW DOWN AND NOTICED THE BRAKES ON THE YUKON WERE NOT FUNCTIONING PROPERLY. MORE SPECIFICALLY, THE BRAKES WOULD NOT FUNCTION THE FIRST 3-4 TIMES WHEN THEY WERE APPLIED OR TAPPED, BUT THEREAFTER THE BRAKES WOULD BECOME HARD AND HE HAD TO DEPRESS THE BRAKE PEDAL AS HARD AS HE COULD BUT WITH LITTLE TO NO STOPPING ABILITY. THE 'BRAKE ASSIST' LIGHT CAME ON. HAD WE BEEN IN ANY TRAFFIC OR ON A SHORTER ROAD, WE WOULD HAVE SURELY CRASHED INTO SOMEONE AND IT COULD HAVE BEEN CATASTROPHIC CONSIDERING WE LIVE IN DALLAS WHERE THERE IS A LOT OF TRAFFIC. THIS DAY WE WERE VERY LUCKY! GM HAD ISSUED A SERVICE BULLETIN #PIT5361B WHICH AFFECTED MULTIPLE YEARS AND CLASSES OF VEHICLES TO INCLUDE THE 2015 YUKON. GM ACKNOWLEDGED THAT 'A CUSTOMER MAY COMMENT ON A HARD BRAKE PEDAL OR THAT INCREASED EFFORT IS NEEDED TO DEPRESS THE BRAKE PEDAL.' AS EVIDENCE OF THE DEFECT, GM NOTIFIED ITS DEALERS, 'WHILE PERFORMING NORMAL DIAGNOSTICS, FLUID MAY BE FOUND IN THE BRAKE BOOSTER AND/OR THE BOOSTER VACUUM LINE.' HOWEVER, WE CALLED MULTIPLE DEALERSHIPS WITHIN THE DFW AREA AND THEY ALL DENIED KNOWING ANY ISSUE WITH GM BRAKES FAILING OR THE VACUUM PUMP. INTERESTINGLY, THERE IS A CLASS ACTION LAWSUIT ON THIS VERY ISSUE AND GM ALSO ISSUED A SERIES OF SERVICE BULLETINS TO ITS DEALERS REGARDING THE BRAKE DEFECT, WITH THE LATEST BULLETIN DATED MARCH 15, 2017, TO INCLUDE THE 2015-2016 YUKON. OURS IS JUST A 2017, 1 YEAR OUTSIDE OF THAT. WHO IS TO SAY THIS YEAR ISN'T AFFECTED CONSIDERING PAST HISTORY OF THE BULLETINS. IT WAS THANKSGIVING HOLIDAY AND NO DEALERSHIP COULD EVEN GET TO IT BESIDES NOT KNOWING OF ANY 'ISSUE', EVEN THOUGH IT'S ALL OVER THE INTERNET.

REAR BRAKE LIGHT IS OUT AND THE VEHICLE ISN'T EVEN 3 YEARS OLD BUT OVER 36,000 MILES. DEALERSHIP STATED LIGHT IS OUT SO WHOLE HOUSING HAS TO BE REPLACED AT $900/EACH.

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.

WHILE STANDING BEHIND THE VEHICLE WITH THE LIFT GATE OPEN, AND ATTEMPTING TO REMOVE ITEMS FROM THE REAR AREA THE LIFT GATE RANDOMLY SLAMS SHUT WITHOUT NOTICE OR WARNING. ON SEVERAL OCCASIONS MY CHILDREN WERE IN THE WAY OF THE LIFT GATE CLOSING AS WELL, HOWEVER, SINCE I AM TALLER I WAS HIT FIRST SAVING MY CHILDREN. ON SEVERAL OCCASIONS I WAS HIT IN THE HEAD AND IT THE BACK BY THE SLAMMING REAR LIFT GATE. I ENSURED THAT I DID NOT HAVE THE KEY FOB ACCIDENTLY ACTIVATED IN MY POCKET AND THAT I DID NOT ACTIVATE THE CLOSURE SENSOR UNDERNEATH THE REAR OF THE VEHICLE. UPON INVESTIGATION BY THE DEALER THE CAUSE WAS IDENTIFIED TO BE THE LIFT GATE MODULE. THE LIFT GATE ALSO REQUIRED RECALIBRATION AND SENSOR ALIGNMENT.

WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE DASH DISPLAYED NUMEROUS AND RANDOM ERROR MESSAGES: (WORDING MAY NOT BE EXACT) SERVICE FRONT COLLISION SYSTEM. FRONT RADAR BLOCKED. FRONT COLLISION SYSTEM UNAVAILABLE. THESE MESSAGES INDICATED A PROBLEM WITH THE FORWARD COLLISION AVOIDANCE SYSTEM. THE WEATHER ON THE PARTICULAR DAY VARIED. ERRORS OCCURRED AT VARIOUS SPEEDS. THIS HAZARD CAN CAUSE SERIOUS HARM IF THE SENSORS DETECT AN IMMINENT FORWARD CRASH IN ERROR AND APPLY THE BRAKES IN TRAFFIC. THIS DANGEROUS SITUATION IS LIKELY TO RESULT IN SERIOUS PERSONAL INJURY OR DEATH. THE ROOT CAUSE WAS DETERMINED TO BE RELATED TO AN ADDITIONAL FAILURE MODE IDENTIFIED IN THE OILY SUBSTANCE LEAKING FROM THE CONTROL BOX MOUNTED ON THE FRONT WINDSHIELD. THIS OILY SUBSTANCE WAS IDENTIFIED BY THE VEHICLE OWNER AND REPORTED TO THE DEALER.
