2017 GMC YUKON Complaints

RIGHT REAR TAILLIGHTS STOPPED WORKING. UNIT IS SEALED AND WHOLE ASSEMBLY MUST BE REPLACED, AT GREAT EXPENSE. THIS APPEARS TO BE A COMMON PROBLEM BUT GM WILL NOT FIX.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE THE CONTACT'S HUSBAND WAS PARKING THE VEHICLE, THE BRAKE PEDAL HAD TO BE DEPRESSED TO THE FLOORBOARD TO MAKE A COMPLETE STOP. ALSO, THE SERVICE BRAKE ASSIST WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO BLAKE FULENWIDER DODGE (LOCATED AT 1310 E MAIN ST, EASTLAND, TX 76448, (254) 488-429) WHERE IT WAS SERVICED PER NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC) ON OCTOBER 18, 2019. AFTER THE CONTACT LEFT THE DEALER, AND WHILE DEPRESSING THE BRAKE PEDAL, THE CONTACT HEARD AN ABNORMAL NOISE COMING FROM THE BRAKES AND THE VEHICLE JERKED FORWARD. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 50,700. THE VIN WAS NOT AVAILABLE.

DRIVERS SIDE LED BRAKE LIGHT DOES NOT FUNCTION. VEHICLE HAS 52,000 MILES. KNOWN DEFECT YET GMC DOES NOT OFFER REPAIR. REQUIRES $800 LIGHT ASSEMBLY REPLACEMENT.

TL* THE CONTACT OWNS A 2017 GMC YUKON XL. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT NOTICED THAT THE REAR BRAKE LIGHTS STOPPED WORKING WITHOUT WARNING. THE VEHICLE WAS TAKEN TO MIDLAND BUICK GMC (3205 W WALL ST, MIDLAND, TX 79701, (432) 897-0665) WHERE IT WAS DIAGNOSED THAT THE LED BRAKE SYSTEM NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE RECURRED MULTIPLE TIMES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE CONTACT WAS ADVISED TO CALL NHTSA TO FILE A COMPLAINT. THE FAILURE MILEAGE WAS APPROXIMATELY 49,000.

THE GMC YUKON MODELS IN ALL TRIMS, HAVE FAULTY LED STRIPS THAT CAUSE THE BRAKE LIGHTS TO FAIL ON THE LEFT, AND RIGHT BRAKE LIGHT ASSEMBLY. THE FRUSTRATING PART IS IT WORKS INTERMITTENTLY, AND WHEN IT'S OFF A SLIGHT TAP WILL MOMENTARILY BRING IT BACK ON FOR THE DURATION OF THE JOLT. THIS LEADS ME TO BELIEVE THAT IT'S FAULTY CONNECTION INSIDE THE SEALS BRAKE LIGHT ASSEMBLY. THERE ARE THOUSANDS OF COMPLAINTS ONLINE ON OWNER FORUMS OF GMC YUKON'S . THIS IS KNOWN AS THE NEW YEAR MODELS 18-19 ARE NOT HAVING THE SAME ISSUE.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE DRIVING 14 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO STOP AND THE BRAKE ASSIST AND CHECK ENGINE WARNING INDICATORS ILLUMINATED. AS A RESULT, THE CONTACT CRASHED INTO ANOTHER VEHICLE. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT A MODE FOR THE BRAKES WAS SWITCHED. THE VEHICLE WAS REPAIRED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSTIC TESTING OR REPAIRS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 27,698.

RIGHT TAIL/BRAKE LIGHT HAS INTERMEDIATE PROBLEM. ADVISED DEALERSHIP, THEY HIT THE LIGHT WITH HAND AND IT FLASHED. GMC IS AWARE THAT THIS IS A PROBLEM. NO DETECTION FROM ANY OF THE SENSORS ADVISING THERE IS A PROBLEM WITH THE TAIL/BRAKE LIGHT. THIS IS OBVIOUSLY AN ISSUE WITH GMC YUKONS WHEREIN THERE IS A BROKEN WIRE IN THE LIGHT ITSELF AND IT IS A FULL UNIT THAT COST APPROXIMATELY $650.00. PRINCE DEALERSHIP DID NOT EVEN ADVISE THAT THERE IS A RECALL ON MY VEHICLE AT THE TIME OF CHECKING THE TAIL/BRAKE LIGHT WAS WARRANTED.

DRIVERS SIDE LED BRAKE LIGHT STRIP INOP. DEALER SAYS ITS 650 PER SIDE PLUS LABOR TO REPLACE. GMC IS AWARE OF ISSUE BUT WILL NOT STAND BEHIND THERE PRODUCT. THEY ALSO LIE AND SAY IT'S THE FIRST THEY HAVE HEARD OF THIS TYPE OF FAILURE. THIS IS A SAFETY CONCERN AND CUSTOMER IS LIABLE FOR A TICKET THAT MAY RESULT FROM FAULTY GM PARTS.

WHILE DRIVING AT SLOW SPEEDS THE TRANSMISSION WILL SUDDENLY SHIFT EXTREMELY HARD INTO FIRST GEAR WHEN WHILE LIGHTLY INCREASING SPEED. THE TRANSMISSION WILL SHIFT EXTREMELY HARD INTO FIRST GEAR WHILE GRADUALLY COMING TO A STOP. OCCASIONALLY WHILE DRIVING SLOWLY (PARKING LOTS) THE TRANSMISSION UPSHIFTS TO SECOND GEAR CAUSING THE CAR TO LURCH FORWARD NEARLY CAUSING A COLLISION. THIS IS A CONTINUING PROBLEM THAT CANNOT BE REPAIRED AT THE DEALERSHIP.

I PURCHASED MY 2017 YUKON DENALI IN 2017. SINCE THE DAY I BOUGHT IT I HAVE NOTICED A PROBLEM WITH APPEARS TO BE THE TRANSMISSION. I WILL BE AT A STOP THEN I ACCELERATE AND THE CAR HAS A HARD SHIFT FORWARD. IT TENDS TO PULL FORWARD ALL OF A SUDDEN BUT VERY VIOLENTLY. I HAVE TAKEN IN MY YUKON TO THE TWO GMC DELERSHIPS IN MY AREA SEVERAL TIMES. THEY HAVE SERVICED IT AND EVEN PERFORMED A TRANSMISSION FLUSH BUT STILL THE PROBLEM HAS ALWAYS CONTINUED. I HAVE BEEN DEALING WITH THIS YUKON PROBLEM FOR TWO YEARS NOW. ITS SO DANGEROUS TO DRIVE.
