DEALERSHIP REPLACED STEERING SHAFT BEARING, RETAINER SPRING, AND SEAT AND PROBLEM HAS RETURNED. ONLINE FORUMS HAVE SHOWN NUMEROUS OTHER GM OWNERS EXPERIENCING THE SAME PROBLEM. SOME HAVE REPORTED STEERING WHEEL LOCATION SENSOR IS CATCHING. OTHERS HAVE REPORTED ENTIRE STEERING SHAFT MUST BE REPLACED AND CLAIM IT IS ON NATIONAL BACK ORDER. THIS IS NOT ONLY A NUISANCE, BUT CREATES CONSTERNATION OVER SAFETY OF STEERING. ISSUE SHOULD BE INVESTIGATED FOR POSSIBLE SAFETY RECALL.

OUR 2015 YUKON XL DENALI HAS BEEN IN FOR REPAIR SERVICE FOR 41 DAYS SINCE PURCHASED NEW 3/23/15. THE CAR HAS STALLED WHILE IN MOTION WITH MY WIFE AND THREE DAUGHTERS IN THE VEHICLE TWICE AND BEEN UNRESPONSIVE TO THROTTLE INPUT 3 ADDITIONAL TIMES. THE STALL OCCURRED ONCE WHILE TURNING LEFT ACROSS TRAFFIC AND ANOTHER TIME WHILE TURNING RIGHT AND MERGING WITH TRAFFIC! THE PROBLEM IS INTERMITTENT AND GMC HAS NEVER BEEN ABLE TO REPLICATE IT. THEY HAVE GIVEN US THE SHOULDER SHRUG, "I DON'T KNOW WHAT TO TELL YOU, WE CAN'T REPLICATE IT" LINE, SO HERE ARE YOUR KEYS. NO WARNING INDICATORS, NO SIGNS IT MAY HAPPEN, AND NO WAY TO PULL UP THE ISSUE WITH THEIR DIAGNOSTICS...HUGE SAFETY CONCERN AND EACH TIME THEY HAVE HANDED US THE KEYS BACK AFTER 7 DAYS (THEIR STANDARD ALLOTTED TIME TO HAVE A LOANER OUT) WITHOUT ANY PROACTIVE ESCALATION TO FIND ROOT CAUSE OR CONCERN FOR MY FAMILY'S SAFETY. THE LAST TIME WE TOOK IT IN, THEY HAD IT FOR 8 DAYS AND COULD NOT REPLICATE THE ISSUE. WE SIGNED OUR SERVICE PAPERWORK AND I ESCALATED TO THE SERVICE MANAGER BEFORE LEAVING. AFTER TELLING HIM WE WOULD BE PURSUING BUYBACK, HE MIRACULOUSLY HAD AN IDEA IT MAY BE RELATED TO A WIRING HARNESS ISSUE. THIS WAS BASED OFF HIS EXPERIENCE WITH A SIERRA PICKUP (5.3L, NOT OUR 6.2L) THAT HAD SIMILAR BEHAVIOR. WE LEFT THE VEHICLE AND, WOULDN'T YOU KNOW IT, THEY REPLACED A WIRE AND "HAVE REASONABLE CONFIDENCE" IT RESOLVED THE ISSUE. TWO WEEKS LATER, IT'S BACK IN THE SHOP FOR KEY FOB NOT DETECTED (AFTER ALREADY DRIVING). TRUCK IS IN GEAR AND YOU CANNOT MOVE...ANOTHER HUGE SAFETY CONCERN. IT'S A DUD. WE HAVE ALSO HAD TO HAVE ALL 8 INJECTORS REPLACED DUE TO ROUGH IDLING AND THE STEERING GEAR REPLACED FROM FAULTY MANUFACTURING THAT CREATES A CLICKING WHILE TURNING THE WHEEL, THE CAR IS AT THE DEALER AND WE WILL NOT BE TAKING IT BACK. WE ARE GOING THROUGH THE OFFICAL BUY-BACK PROCESS WITH GMC.

OUR VEHICLE HAS A SIGNIFICANT VIBRATION IN V4 MODE WHEN TRAVELING BETWEEN 45-65 MPH AND ABOVE. THE VIBRATION IS ALSO ACCOMPANIED BY INCREASED CABIN PRESSURE. THESE ISSUES ARE CAUSING HEADACHES, NAUSEA, DIZZINESS, AND ARE FURTHER EXACERBATING MY WIFE'S MULTIPLE SCLEROSIS. WE ALSO HAVE A POPPING SOUND COMING FROM THE REAR OF THE VEHICLE'S SUSPENSION WHEN TURNING THAT MAKES US FEEL UNSAFE. THE VIBRATION STARTED RIGHT AFTER WE TOOK DELIVERY OF THE CAR AND HAS ONLY GOTTEN WORSE. WE BOUGHT THE CAR IN APRIL 2015 AND THE ISSUE CONTINUES UNFIXED TO THIS DAY. THE POPPING NOISE STARTED ABOUT 3-4 WEEKS AGO AND IT SOUNDS LIKE A SUSPENSION COMPONENT. OUR AC RECIRCULATING FEATURE ALSO DOES NOT WORK AND IT ALLOWS HARMFUL EXHAUST SMOKE IN.

I AM WRITING TO NOTIFY YOU ABOUT A PROBLEM WITH THE TRANSMISSION IN 2015 GMC YUKON XL. GM IS AWARE OF A PROBLEM. THEY ISSUED AN INTERNAL NOTICE TO DEALERS IN FEBRUARY 2016. HOWEVER, THEY HAVE NOT NOTIFIED TO OWNERS IN THE FORM OF A RECALL. ON SEVERAL OCCASIONS, MY VEHICLE JUMPED FORWARD, WHILE DRIVING IN THE CITY, WHEN IT WAS STOPPED, IN DRIVE, WITH BRAKE ENGAGED. I REPORTED TRANSMISSION PROBLEMS TO MY LOCAL DEALER BUT THEY REPEATEDLY IGNORED MY CONCERNS. THEY KEPT GIVING EXCUSES THAT DIDN'T MAKE SENSE. I FINALLY PRESSED ON, REFUSED TO TAKE MY VEHICLE BACK AND REPORTED THE PROBLEM TO SEVERAL EXECUTIVES. THE PROBLEM WAS FINALLY DIAGNOSED UNDER DIFFERENT CONDITIONS AS STATED IN THE FIRST INTERNAL DOCUMENT IN MARCH 2016. THERE WAS A PROBLEM WITH THE TRANSMISSION. THEY FINALLY REPLACED THE TRANSMISSION FOR "ONE THAT DIDN'T HAVE A PROBLEM". GM ADMITTED THERE ARE PROBLEMS WITH TRANSMISSIONS AND THE PROBLEM HAS BEEN CORRECTED IN NEWER VEHICLES. THEY HAVE YET TO ISSUE A NOTICE TO CURRENT OWNERS THAT THEIR VEHICLES ARE AT RISK. I OWNED A 2015 GMC YUKON XL BUT CHOSE TO SELL IT OVER SAFETY CONCERNS AND LACK OF APPROPRIATE RESPONSE FROM GM CORPORATE. WITH 2 YOUNG CHILDREN, I SPEND A LOT OF TIME AROUND SCHOOLS (LIKE MOST OWNERS OF LARGE GM VEHICLES). I COULD HAVE INJURED OR KILLED SOMEONE. I FEEL IT IS MY OBLIGATION TO BRING THIS SITUATION TO YOUR ATTENTION. IF YOU INTERVENE, YOU CAN HELP TO AVOID ANY INJURIES IN THE FUTURE. IT IS CLEAR THAT GM WILL NOT VOLUNTARILY PROTECT THE PUBLIC.

ON FEBRUARY 10, 2016, WE WERE DRIVING ON I-25 HEADED TO ARIZONA FOR A VACATION. AS WE WERE JUST ON THE OUTSKIRTS OF SANTA FE, NM, WE HEARD A LOUD EXPLOSION AND IT SOUNDED LIKE OUR ENTIRE CAR WAS BLOWING UP. WE WERE DRIVING AT 75 MPH AND THERE WERE NO OTHER CARS CLOSE TO US. WE STARTED HEARING GLASS BOUNCING AROUND ON THE SUNROOF CURTAIN AND REALIZED THAT IT WAS OUR SUNROOF THAT HAD EXPLODED. WE PULLED INTO THE FIRST EXIT IN SANTA FE AND CHECKED THE CAR AND THE GLASS APPEARED TO HAVE EXPLODED UPWARDS. WE DROVE TO THE NEXT GAS STATION AND PULLED OUT ALL THE LARGE PIECES AND VACUUMED UP WHAT WE COULD OF THE SMALL PIECES. NEEDLESS TO SAY, WE HAD TO END OUR VACATION AND WE TURNED AROUND AND DROVE HOME THE SAME DAY. ALL WE COULD HEAR ON THE WAY HOME WAS GLASS BOUNCING AROUND AND THE ROAD NOISE. WE CONTACTED GMC AND THEY SAID WE SHOULD CLAIM THROUGH OUR INSURANCE. EVENTUALLY, THEY RELENTED AND REPLACED THE SUNROOF. I HAVE DONE RESEARCH ON THE INTERNET AND IT APPEARS THAT THIS IS HAPPENING WITH MANY MAKES OF VEHICLES NOT JUST GMCS. IT APPEARS THERE ARE SOME SERIOUS ISSUES WITH SUNROOFS. IF PICTURES ARE NEEDED, WE TOOK SEVERAL AND I WOULD BE HAPPY TO PROVIDE. THANK YOU FOR ADDRESSING THE ISSUES WITH SUNROOFS. I NO LONGER FEEL SAFE IN THIS CAR AND THIS IS A VEHICLE THAT WE PURCHASED FOR ROAD TRIPS AS WE HAVE TWO OTHER VEHICLES WHICH ARE OUR EVERY DAY VEHICLES. IT WAS THE SCARIEST THING WE HAVE EVER EXPERIENCED. *TR

EARLIER THIS YEAR I PURCHASED A 2015 GMC YUKON DENALI. AFTER DRIVING IT A SHORT AMOUNT OF TIME I REALIZED THE BRAKE PEDAL IS LOCATED SIGNIFICANTLY HIGHER THAN THE GAS PEDAL. I'VE COME TO REALIZE THAT THE ~4INCH GAP IS CAUSING A SEVERE SAFETY HAZARD, ESPECIALLY IN EMERGENCY BRAKING SITUATIONS. MY FOOT, ALONG WITH OTHERS IN THE POST LINKED BELOW, OFTEN GETS CAUGHT IN THE LARGE GAP BETWEEN THE GAS AND THE BRAKE, ESPECIALLY WHEN MOVING QUICKLY. THERE HAVE BEEN MANY INSTANCES TO DATE WHERE THE SOLE OF MY SHOES HAS GOTTEN STUCK UNDER THE BRAKE PEDAL, PREVENTING ME FROM STOPPING IN TIME. I'VE NARROWLY AVOIDED AT LEAST 5 ACCIDENTS, BECAUSE OF THIS. FEARING THAT IT IS A MATTER OF TIME BEFORE IT RESULTS IN A COLLISION I REACHED OUT TO GMC TO SEE IF THERE WAS A FIX. THEY RESPONDED AND SAID THAT THE PEDALS ARE WORKING AS DESIGNED AND SAID THERE WAS NOTHING THAT CAN BE DONE. I'M VERY DISAPPOINTED IN THEIR RESPONSE, ESPECIALLY CONSIDERING THE CLEAR SAFETY HAZARD IT CREATES. IT IS A LARGE CAR, REQUIRING MORE BRAKING DISTANCE THAN MOST. ANY IMPEDANCE TO THE PROCESS SHOULD BE TAKEN SERIOUSLY ESPECIALLY IF IT IS A MANUFACTURER DESIGN FLAW SUCH AS THIS. SIMILAR COMPLAINTS HAVE BEEN VOICED IN THIS ONLINE CONSUMER THREAD. ONE OF MANY THAT I FOUND REITERATING THE PROBLEM. HTTP://WWW.TAHOEYUKONFORUM.COM/THREADS/GAS-BRAKE-PEDAL-DISTANCE.67500/

Official recalls
10Oct 24, 2019
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Consequence & remedy
Consequence: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
Consequence & remedy
Consequence: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.
Sep 7, 2018
General Motors LLC (GM) is recalling certain 2015 Chevrolet Silverado 1500, Tahoe and Suburban, GMC Sierra 1500 and Yukon, and Cadillac Escalade vehicles. Electric power steering (EPS) assist may be lost momentarily, followed by a sudden return of EPS assist.
Consequence & remedy
Consequence: If EPS assist is lost and then suddenly returns, the driver may have difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will update the EPS module software, free of charge. The recall began October 12, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 and GMC customer service at 1-800-462-8782. GM's number for this recall is 18289.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
Consequence & remedy
Consequence: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

1PE18012 · 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.
