PURCHASE A USED 2015 YUKON DENALI 1 YEAR AGO AND HAVE HAD ISSUES WITH BOTH SHOCKS AND AC. THE SHOCKS ARE THE AIR RIDE AND ALL 4 HAD TO BE REPLACED. THIS WAS A HUGE EXPENSE BECAUSE MY TRUCK SURPASSED THE MILEAGE EVEN THOUGH IT WAS WITHIN THE DATE RANGE. MY AC ALSO RESENTLY STOPPED WORKING. I RECEIVED A LETTER FROM GM 1DAY AFTER AC WENT OUT NOTIFYING ME ABOUT A KNOW ISSUE WITH A LEAKING COMPRESSOR. I TOOK IT TO THE DEALERSHIP THE NEXT DAY AND THOUGHT IT WOULD BE COVERED TO REPLACE. I THEN FOUND OUT THAT SINCE IT WAS OVER MILEAGE IT WASN'T UNDER WARRANTY. I QUESTIONED WHAT MILEAGE AD TO DO WITH A KNOW DEFECTIVE COMPRESSOR BUT WAS TOLD THEY COULD NOT DO ANYTHING. THE COST TO REPLACE IT WAS QUOTED AT $1,200.

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.

A STRONG VIBRATION OR "SHUDDER" RESONATES THROUGHOUT THE BODY OF THE ENTIRE CABIN. FEELS LIKE YOU ARE DRIVING OVER LARGE RUMBLE STRIPS, EVEN WHEN THE ROAD IS COMPLETELY SMOOTH. APPEARS TO OCCUR AT SPEEDS GREATER THAN 30 MILES PER HOUR AND WHEN THE RPMS EXCEED 1,000 RPM. THE RPM NEEDLE "JUMPS" REPEATEDLY WHILE THE VIBRATION/SHUDDER OCCURS. WHEN WE TOOK IT TO THE LOCAL GMC DEALER, THEY TOLD US IT WE NEEDED A NEW WHEEL FOR WHICH WE BOUGHT AND IT ACCOMPLISHED NOTHING. THEN, WE RETURNED IT, DESCRIBED THE PROBLEM IN EXCRUCIATING DETAIL - EVEN REFERENCING KNOWN PUBLIC SERVICE BULLETINS - WHICH PROMPTED THEM TO "BALANCE THE TIRES." LEFT THE GMC DEALERSHIP AGAIN AND IT WAS OBVIOUS THE DEALERSHIP DID NOT ADDRESS THE PROBLEM AND THAT IT HAD NOTHING TO DO WITH THE WHEELS. WE RETURNED AND ADVISED THEM THEY DID NOT FIX THE PROBLEM. THE KEPT THE DENALI AGAIN AND THEN ADVISED US THEY WERE "100% SURE" THE PROBLEM WAS THE "SHOCKS". THEY REPLACED THE SHOCKS FOR NEARLY $2,000 AND ADVISED US BY PHONE THE PROBLEM WAS "FIXED." I ASKED THE REPRESENTATIVE IF THEY HAD CONFIRMED IT WAS FIXED AND HE SAID "YES", THE TECHNICIAN HAD DRIVEN THE VEHICLE AND THERE WERE NO FURTHER ISSUES. MINUTES LATER, I GOT A CALL FROM THE SERVICE MANAGER WHO ADVISED THE CUSTOMER SERVICE REPRESENTATIVES CALL TO ME WAS "PREMATURE" (I GUESS HE FINALLY DECIDED TO DRIVE THE VEHICLE) AND ADVISED THERE WAS A PROBLEM WITH THE TORQUE CONVERTER AND THAT HE NEEDED TO KEEP IT FOR A FEW MORE DAYS. I ASKED WHY HE THEY HAD TOLD ME THEY WERE "100% SURE" THE PROBLEM WAS THE SHOCKS AND HE ADVISED HE DROVE IT AND THEY "SEIZED" UP. WE ARE STILL AWAITING SOME RESOLUTION TO THIS $75,000 NEW VEHICLE DISASTER. THIS IS THE FIRST AMERICAN VEHICLE WE HAVE PURCHASED AND ARE CERTAINLY REGRETTING THAT DECISION AND ARE CURRENTLY RESEARCHING OTHER FULL-SIZE SUVS FOR BETTER SAFETY AND RELIABILITY.

WHEN SHIFTING INTO GEAR FROM A CHILD START, THE VEHICLE TAKES APPROXIMATELY 3 SECONDS TO SHIFT. DURING THAT TIME THE VEHICLE IS NOT IN GEAR AND CAN ROLL IN ANY DIRECTION. THERE IS A SOFTWARE FIX FOR THIS THAT I MUST PAY THE DEALER TO INSTALL. THIS HAPPENS EVERY COLD START.

DEALERSHIP HAS FIVE MORE CONDENSERS TO REPLACE AFTER MINE WAS REPLACED THIS PAST FRIDAY MAY 26TH, 2017. CALLED ANOTHER DEALERSHIP TO SEE IF POSSIBLE TO GET A CONDENSER QUICKER AND THE WAIT WAS FIVE VEHICLES AHEAD OF ME. THIS IS A LARGE PROBLEM IN 2015 AND 2016 YUKON'S, ESCALADE'S, AND TAHOE'S. I WANT THIS TO BE A WARRENTY EXTENSION FOR ALL OWNERS.

VEHICLE DRIVE TRAIN OPERATES ERRATICALLY IN VARIOUS OPERATING SITUATIONS AND HAS EXTENSIVE VIBRATIONS BETWEEN 25-40MPH; VIBRATIONS ARE WORSE IN CERTAIN GEARS. SIGNIFICANT LUNGEING AND JERKING OF SHIFTING GEARS ON ACCELERATION, PARTICULARLY WHEN NOT ACCELERATING INTENSELY. VEHICLE MAKES A CLUNK/KNOCK SOUND WHEN DECELERATING RAPEDLY. TAKEN IN FOR SERVICE 2X AT 2 DIFFERENT GMC DEALERS. TRANSMISSION HAS BEEN REPROGRAMMED 1X. NITHER DEALER PROVIDED GMC TECHNICAL SERVICE BULLETIN "#99-04-20-002I: INFORMATION ON DRIVE TRAIN CLUNK NOISE - (NOV 18, 2014)" AFTER MY VEHICLE WAS TAKEN ON AN UNAUTHERIZED 30 MILE 'TEST DRIVE' I WAS TOLD 'IT'S NORMAL OPERATION' AND "CUSTOMER CONCERN NOT DUPLICATED AT THIS TIME". SIMPLY FIND THIS HARD TO BELIEVE AS THE OPERATIONS AS DESCRIBED ARE BEING ACKNOWLEDGED BY A GMC BULLETIN. THIS IS SERIOUS: (1) THE SUDDEN JERKING/SLAMMING OF GEARS WILL HAVE A LONG TERM EFFECT ON THE TRANSMISSION (2) THE ACCELERATION ON DOWNSHIFTING IS A HUGE LIABILITY AS THE INCREASED POSSIBILITY OF COLLISION IS SIGNIFICANT AND (3) DIFFINETLY NOT 'NORMAL' OPERATION.

PE18012 · Brake Vacuum Pump Failure
Opened Nov 20, 2018 · Closed Apr 10, 2022
Status: closed (inferred from source dates) · Service Brakes; Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:vacuum
On November 20, 2018, the Office of Defects Investigations (ODI) opened PE18-012 to investigate instances of sudden onset of a hard brake pedal that could result in extended stopping distance due to an issue with the brake assist vacuum pump in model year (MY) 2014 through 2016 GMC Sierra 1500 and Chevrolet Silverado 1500 series pickup trucks and MY 2015 through 2016 Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe, and GMC Yukon SUVs.If the brake assist vacuum pump fails to operate as intended, the amount of brake power assist supplied to the driver can be significantly reduced, extending the subject vehicle stopping distance. GM stated that the root cause of pump failures was due to foreign debris such as oil sludge in the engine oil. GM stated that this debris can become trapped by the oil inlet filter screen. Under normal operation, this screen allows a small amount of oil into the brake vacuum pump. The foreign debris can, over time, clog the pump which can cause a loss of lubrication and a reduction in the amount of vacuum produced leading to a hard pedal and extended stopping distance.On December 13, 2018, GM issued a Special Coverage (N182202780) for the brake vacuum pump issue in MY 2014-2017 trucks and 2015-2017 SUVs on the K2XX platform for 6 years or 72,000 miles. Special Coverage repair includes the replacement of the vacuum pump and vacuum pump belt. Consumers received notification of the coverage via mail. On September 6, 2019, GM notified NHTSA that it was conducting safety recall 19V-645 which reprograms the electronic brake control module (EBCM) and included approximately 3.5 million trucks and SUVs. In October 2019, GM extended the terms of special coverage N182202780 to 10 years or 150,000 miles as well as now including the entire scope of recall 19V-645. In October 2020, GM expanded the scope of coverage N182202780 to include the MY 2018 Escalade and 2019 Tahoe.The remedy implemented in GM recall 19V-645 appears to be sufficient in addressing the safety-related concerns of this issue. Loss of vacuum assist now occurs at a progressive rate as well as there being a more timely warning of a brake problem to the driver through the driver information center (DIC). In view of the recall action and revision to the special coverage, this Preliminary Evaluation is closed. The agency reserves the right to take additional action if warranted by new circumstances. The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.
