VEHICLE WAS IN MOTION PULLING INTO DRIVEWAY TO PARK IN GARAGE AND VEHICLE WOULD NOT STOP CORRECTLY, ALMOST RESULTING IN ME HITTING MY GARAGE DOOR PILLAR. AS I BACKED UP, STARTED TO PULL FORWARD INTO MY GARAGE STALL, VEHICLE BREAK PEDAL WAS HARD AND CAR WOULD NOT STOP, AGAIN ALMOST HITTING MY FRONT WALL. SAME THING HAPPENS GOING IN REVERSE. BRAKE POWER WOULD COME AND GO. FEELS AS THOUGH FRONT RIGHT BREAK WOULD LOCK BUT NOT STOP, AND EVENTUALLY ALL STOPPING POWER WOULD GO AWAY.

PURCHASED A USED 2017 GMC YUKON DENALI WITH ALMOST 36,000 MILES. 4 DAYS AFTER THE PURCHASE MY ENGINE LIGHT CAME ON. NEXT MORNING THE VEHICLE WAS NOT DRIVING RIGHT, VERY SLOW MOVING (COULDN'T GO FASTER THAN 45 MILES PER HOUR), VERY SHAKY, LOUD, FELT LIKE IT WAS EITHER GOING TO DIE ON ME OR BLOW UP. HAD ONSTAR CHECK IT OUT WITH SEVERAL ISSUES REPORTED, TOOK TO DEALERSHIP RIGHT AWAY. 3 FUEL INJECTORS WERE FAILING AND WERE REPLACED STILL UNDER WARRANTY. FUEL INJECTOR #3 WAS REPLACED PRIOR TO MY PURCHASE OF THIS VEHICLE AND NOW AGAIN REPLACED ALONG WITH INJECTOR #5 & #8. 2 WEEKS LATER ENGINE LIGHT CAME ON AGAIN. DROVE OK, TOOK TO DEALERSHIP, FUEL INJECTOR #1 NOW GOING OUT. PARTS ON BACK ORDER....GOT A CALL THIS MORNING THAT PARTS ARE IN (HAD TO WAIT OVER A WEEK). I AM NOW OVER THE 36,000 MILES AND WILL THEREFORE BE PAYING TO REPLACE THIS INJECTOR. OPTED TO HAVE ALL THE OTHER INJECTORS REPLACED AS WELL. VERY DISAPPOINTED IN THIS VEHICLE AS IT IS ONLY 2 YEARS OLD. I AM A SINGLE MOM AND NEED A RELIABLE VEHICLE, WHICH THIS VEHICLE IS LESS THAN RELIABLE. HAD THIS VEHICLE A MONTH AND ITS BEEN NOTHING BUT A HEADACHE AND IN THE SHOP 3 TIMES. THESE ISSUES MUST BE COMMON SINCE THE FUEL INJECTORS WERE ON BACKORDER AND THIS PROBLEM SHOULD HAVE A RECALL.

THE BRAKE PEDAL IS SEVERELY CLOSER THAN THE ACCELERATOR FROM THE DRIVER. WHEN TRYING TO STOP QUICKLY, THE DRIVER HAS TO LIFT FOOT SUBSTANTIALLY TO SHIFT OVER TO APPLY PRESSURE TO THE BRAKE. THIS IS EXTREMELY DANGEROUS AND TERRIBLY UNCOMFORTABLE. THE FOOT PEDALS, EVEN WITH THE ADJUSTMENTS, ARE TOO CLOSE TO THE DRIVER.
