2016 GMC YUKON DENALI Complaints

FRONT BRAKE CALIPERS STICKING CAUSING PREMATURE WEAR OUT OF PADS AND DRIVER SIDE ROTOR AT ~11900 MILES. AFTER FIRST REPAIR, ~900 MILES AND THREE WEEKS LATER, WHILE DRIVING DOWN A SNOW COVERED CITY HILL ABS WAS ENGAGED FOR A SHORT PERIOD OF TIME AND THEN DASH DISPLAYED A "BRAKE FAILURE" WARNING. AFTER THE MESSAGE THE FRONT BRAKES LOCKED UP COMPLETELY, CAUSING LOSS OF CONTROL OF THE VEHICLE AND INDUCED A SLIDE OF OVER 1000FT DOWN THE HILL. ONCE THE VEHICLE FINALLY CAME TO A STOP, A LOUD SOUND WAS COMING FROM THE UNDER CARRIAGE. POWERING DOWN THE VEHICLE DID NOT STOP THE SOUND. RESTART OF THE VEHICLE DISPLAYED "SERVICE STABILITRACK" AND "SERVICE TRAILER BRAKE" WARNINGS. THE ABS, TRACTION CONTROL SLIPPAGE, AND BRAKE LIGHTS ALSO ALL STAYED ILLUMINATED. VEHICLE HAD TO BE TOWED TO DEALER AS IT WAS UNSAFE TO DRIVE. UPON INSPECTION AT GMC DEALER THEY REPORTED THE ELECTRONIC BRAKE CONTROL MODULE (EBCM) WAS SHORTED OUT INTERNALLY AND SECOND FRONT ROTOR WAS ALSO SCORED. THEY REPLACED THE EBCM AND ROTOR UNDER WARRANTY. I'M TOLD THE CALIPER STICKING ISSUE IS COMMON, AND THIS IS NOT THE FIRST EBCM THEY HAVE REPLACED. IN SUMMARY, DAMAGE TO ROTORS AND PADS IS VERY DANGEROUS. AS THE VEHICLE ONLY HAS ~12000 MILES NO ONE WOULD EXPECT THIS TYPE OF WEAR. THE FAILURE OF THE ABS SYSTEM NEARLY CAUSED AN ACCIDENT THAT COULD HAVE BEEN FATAL AS THE VEHICLE WAS DESCENDING A HILL AND AT THE VERY TIME THE ABS WAS NEEDED IT CAUSED LOCK UP OF THE FONT WHEELS INDUCING A SLIDE AND LOSS OF ABILITY TO STEER. *TR

SINCE THE DAY I PURCHASED THIS 2016 GMC YUKON XL DENALI THERE HAS BEEN A VIBRATION IN WHAT I THINK IS THE PASSENGER REAR END. I'VE TAKEN IT IN 3 TIMES AND EACH TIME THE DEALER AND THE GM REPRESENTATIVE SAY IT IS "WITHIN SPEC." THIS PROBLEM HAS PERSISTED. THE VEHICLE IS NOW ALMOST UN-DRIVABLE DUE TO THE SHAKING. IT AFFECTS THE STEERING WHEEL AT ALL SPEEDS. THIS HAPPENS AT ALL SPEEDS ON ALL TERRAINS. THIS HAPPENS WHEN THE VEHICLE IS COLD AS WELL AS WARM/HOT. THE VEHICLE WILL SOMETIMES JERK TO THE LEFT OR RIGHT WHEN THE SHAKING GETS REAL BAD. THIS VEHICLE IS BECOMING DANGEROUS TO DRIVE BUT I HAVE TO USE IT. I AM NOT THE ONLY ONE WITH THIS ISSUE AND WOULD APPRECIATE SOME HELP.
