HAD THIS VEHICLE FOR NINETEEN MONTHS, 50,000 MILES, BROUGHT NEW, RIGHT BRAKE WORKS INTERMITTENTLY OR NOT AT ALL. THESE LIGHTS ARE COMPLETELY SEALED AND LIGHTS ARE NOT REPLACEABLE, EXCEPT REVERSE BULB. GONE OVER 30,000 MILES SO WARRANTEE NOT COVERED. DEALERSHIP WANTS RIDICULOUS PRICE FOR REPLACEMENT. WHY WOULD YOU DO THIS? LIGHTS NEED TO BE CHANGED SOONER OR LATER? ISN'T IT EASIER TO CHANGE A BULB RATHER THEN AN ENTIRE EXPENSIVE UNIT?

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.

TAKATA RECALL - THE VEHICLE IS CONSTANTLY STATING THAT THE SIDE DETECTION IS TEMPORARILY UNAVAILABLE. WHEN DISCUSSING WITH THE DEALERSHIP THEY STATED THAT THEY ARE AWARE OF THE PROBLEM AND IT IS HAPPENING WITH ALL THE MODELS THAT HAVE SIDE DETECTION SENSORS. THE SENSORS ARE FAILING AND WILL LEAD TO THE VEHICLE NOT STARTING AT ALL IF IT IS NOT REPAIRED IN A TIMELY MANNER AFTER SEEING THE NOTIFICATION ON THE DASH. THEY ARE REQUIRING THE CUSTOMERS TO PAY FOR THE REPAIR EVEN THOUGH IT IS SOMETHING THAT IS A KNOWN PROBLEM ACROSS MODELS AND NOT SPECIFIC TO ONE MODEL VEHICLE.
