NHTSA investigations into the 2015 GMC Yukon Denali

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

STEERING

WAS DRIVING ABOUT 7-10 MPH IN A WAL MART PARKING LOT WHEN THE STEERING ON MY 2015 GMC YUKON DENALI COMPLETELY GAVE OUT WHICH CAUSED ME TO SCRAP A POLE ON THE BACK DOOR BEHIND DRIVER. FINALLY WHEN VEHICLE CAME TO A COMPLETE STOP THE STEERING WHEEL WOULD FREELY SPIN AND NOT IN GAUGE THE TIRES TO ROTATE. HAD THE VEHICLE TOWED TO THE NEAREST GMC DEAR SHIP TO HAVE THEM ASSES THE PROBLEM AND TOLD THEM THIS HAS TO BE FROM THE ROOT CAUSE OF A RECALL THAT A SENSOR WILL LOSE TEMP CONNECTION WITH STEERING AND MAY CAUSE AN ACCIDENT. WHICH DID AS WELL AS INJURY TO MY WIFE WHO WAS DRIVING. NOW THE VEHICLE IS AT THE GMC DEALERSHIP GIVING ME A RUN A ROUND THAT THE STEERING COLUMN MAGICALLY SNAPPED AND NEEDS TO BE COVERED THROUGH EXTENDED WARRANTY. I HAVE AN OPEN COMPLAINT WITH THE DEALERSHIP AS WELL AS GMC IT SELF. PLEASE IF YOU OWN THIS YEAR VEHICLE BE VERY CAREFUL THIS COULD HAVE BEEN A REALLY HORRIBLE SITUATION.

POWER TRAIN

I WAS RECENTLY IN AN ACCIDENT AT A STOPLIGHT. WHEN I ARRIVED AT THE STOPLIGHT SOMETHING FELL OUT OF PASSENGER SEAT ONTO FLOOR. I PUT THE TRUCK IN PARK, TOOK OFF MY SEATBELT, LEANED OVER TO PICK UP ITEM AND PUT IT BACK ON THE SEAT. I THEN PUT SEATBELT BACK ON AND PUT FOOT ON BRAKE AND PUT THE TRUCK INTO DRIVE. IT ALL HAPPENED PRETTY QUICKLY AND CAN'T SWEAR TO THE SPECIFICS BUT I THINK THE TRUCK MAY HAVE "JUMPED" A LITTLE WHEN I PUT THE TRUCK INTO DRIVE AND PROPELLED ME INTO THE CAR IN FRONT OF ME AT A VERY LOW SPEED. THE REASON WHY I BELIEVE THIS HAPPENED IS THAT I HAD PREVIOUSLY ASKED THE LOCAL GMC DEALER SERVICE CENTER IF THERE WERE ANY RECALLS OR OTHER REPORTS ON THIS TYPE OF THING HAPPENING BECAUSE IT HAPPENS WITH MY TRUCK. I HAD BEEN EXPERIENCING THIS "ENGINE JUMPING" UPON PUTTING IT INTO DRIVE ISSUE FOR SEVERAL MONTHS.

I HAVE BEEN HAVING ISSUES FOR ABOUT A YEAR WITH THE LIGHTS WORKING INTERMITTENTLY. AS OF TODAY, JUNE 12 2019, THEY ARE OUT COMPLETELY!!!! AFTER GOING TO A LOCAL MECHANIC HE SAID THE WHOLE CIRCUIT WAS GONE & WOULD HAVE TO BE REPLACED!!! I AM IN BETWEEN JOBS AND DO NOT HAVE 2000.00 DOLLARS TO FIX SAID PROBLEM. I HAVE FOUND SEVERAL MESSAGE BOARDS WHO HAVE ALL HAD THE SAME PROBLEM WITH NO HELP WHAT SO EVER FROM GMC!!!!! THIS IS RIDICULOUS. WHEN YOU MAY THOUSANDS OF DOLLARS FOR A SUV YOU EXPECT IT TO LAST LONGER THAN 88,000!!! THIS ISN'T THE FIRST PROBLEM I HAVE HAD WITH THIS SUV. SO THIS NEEDS TO BECOME A RECALL ISSUE AND GMC OR THE PART SUPPLIER NEEDS TO FIX THIS.
