VERY CONCERNED ABOUT MY 2015 YUKON XLT. THE VEHICLE'S GEAR SHIFTED TO A NEUTRAL OF VERY LOW GEAR (NOT VERY SURE) AS I WAS DRIVING DOWN A LONG HILL NEAR BIRMINGHAM, AL. IT FELT LIKE IT WENT TO FIRST GEAR, BUT AT THE SAME TIME IT DID NOT SLOW THE VEHICLE DOWN, ALMOST FELT LIKE THE GEAR WAS GRINDING. THE TRUCK DID NOT CATCH BACK INTO NORMAL GEAR UNTIL THE VEHICLE LEVELED BACK AT THE BOTTOM OF THE HILL. (IT WAS EXTREMELY SCARY AND WORRISOME EVER SINCE THEN, THE TRANSMISSION WILL NOT SHIFT SMOOTHLY.

I HAVE A 2015 YUKON DENALI AND I WAS DRIVING 65 ON THE HIGHWAY AND THE ENGINE SHUT DOWN COMPLETELY. A WARNING MESSAGE SAID ENGINE POWER FAILURE. I HAD 4 CARS AND AN 18 WHEELER BEHIND ME AT THE TIME. I MANAGED TO PUT THE VEHICLE IN NEUTRAL AND COAST TO THE SIDE OF THE ROAD ONTO A MEDIAN. IT WAS TOWED TO THE DEALERSHIP WHERE THEY STARTED TRYING SAY IT MIGHT HAVE BEEN BAD GAS. THEN I WAS TOLD I CRACKED VALVE AND THEY ALREADY HAD ONE OTHER JUST LIKE THIS, THEN 1 DAY LATER AFTER A TECH LEVEL 2 AND A SHOP FORUM LOOKED AT IT, AND A CONVERSATION WITH A GM PAC REP, GM APPROVED A COMPLETE ENGINE REPLACEMENT! I WAS SHOCKED. I'VE HAD THE SAME 4-WHEEL DRIVE ISSUES EVERYONE ELSE HAS. I'VE ALSO HAD A/C PROBLEMS, STEER WHEEL POPPING NOISES, SUNROOF LOUD WIND NOISES. MY SEAT SHIFTS WHEN I DRIVE IT. THE A/C SEATS DON'T COOL PROPERLY, WHICH I FOUND OUT WHEN THEY PUT ME IN A LOANER YUKON THAT WORKED FINE. THE SPEEDOMETER GAUGE ALSO DIDN'T WORK FOR 2 DAYS, WHICH I HAVE A PICTURE OF AND RECEIVED A WARNING TICKET FOR WHEN I WAS PULLED OVER BY AN OFFICER NOT KNOWING WHAT SPEED I WAS GOING. I PASSENGER STEP GUARD DOESN'T ALWAYS RETRACT PROPERLY. MY UNIT WAS PURCHASE MAY 2014 AND WAS ONE OF THE FIRST 4 X 4 UNITS THAT WAS PRODUCED AND HAS HAD CONSTANT PROBLEMS. GM KEEPS DENYING A BUYBACK, THEN NO TRADE ASSISTANCE, THEN NOW HAS OFFERED AN EXTENDED WARRANTY. THIS PARTICULAR VEHICLE I HAVE IS NOT SAFE FOR MY FAMILY TO BE RIDING IN. I CAN'T TRADE IT IN OR SELL IT TO ANYONE ELSE KNOWING THE PROBLEMS IT HAS. THE DEALER WON'T EVEN TAKE IT BECAUSE THEY KNOW THE PROBLEM THAT THEY ARE DEALING WITH. *TR

MY NEW, 2015 GMC DENALI IS EQUIPPED WITH A BACKUP CAMERA AND THE QUALITY IS SO POOR AT NIGHT, AS TO MAKE IT NEARLY MORE DANGEROUS TO USE THAN TO IGNORE IT. I HAVE HAD 3 PRIOR GMC DENALI AUTOMOBILES. THE MOST RECENT WAS A 2011 WHICH WAS TRADED IN FOR THIS NEW ONE. THE QUALITY OF THE BACKUP CAMERA IN THE 2011 MODEL WAS EXCELLENT. MY WIFE AND I IMMEDIATELY NOTED ON THE NEW CAR THAT THE CAMERA IMAGE WAS SO BLURRY AND POOR RESOLUTION AT NIGHT, WE COULD NOT SAFELY USE THE CAMERA TO BACK OUT OF OUR GATED DRIVEWAY. IN THE DAYTIME, THE IMAGE IS BLURRY AS WELL, BUT USABLE. GMC HAS HAD THE CAR TWICE FOR SERVICE AND WE HAVE COMPLAINED TO GMC CORPORATE AND ALL WE GET IS A STATEMENT THAT THE "SYSTEM IS WORKING NORMALLY" WHICH IS DIFFICULT TO ACCEPT. THE NHTSA'S OWN STATISTICS SHOW THAT EACH YEAR APPROX. 20 PEOPLE DIE AND 15,000 ARE INJURED DUE TO BACKUP INCIDENTS. THEIR GUIDELINES STATE A CAMERA NEEDS TO DISPLAY (CLEARLY I WOULD ASSUME) A 10 X 20 FOOT ZONE BEHIND THE VEHICLE. AT NIGHT, YOU CANNOT SEE 20 FEET CLEARLY BEHIND THIS VEHICLE, EVEN IN A WELL LIGHTED STREET. I AM CONVINCED THAT THIS POOR QUALITY SYSTEM IS GOING TO CAUSE ACCIDENTS IF IT HAS NOT DONE SO ALREADY. GMC HAS AN OBLIGATION TO ADDRESS WHAT I BELIEVE IS A SUB-STANDARD QUALITY IMAGE. THEY CANNOT DEFEND THE FACT THAT THE IMAGE IS MUCH WORSE THAN OLDER MODELS OF THEIR VEHICLES. FORTUNATELY, THE NEW DENALI MODEL DOES HAVE A SENSOR SYSTEM THAT PROVIDES A VIBRATORY WARNING IF YOU ARE ABOUT TO CONTACT AN OBJECT, BUT OBVIOUSLY THE DRIVER NEEDS TO SEE CLEARLY BEHIND THEM, BEFORE THEY ARE ABOUT TO STRIKE AN OBJECT IN THEIR PATH. I AM HOPING YOUR AGENCY CAN CONTACT GMC TO HELP MOTIVATE THEM TO ADDRESS THIS ISSUE AND IMPROVE THE SAFETY OF THEIR VEHICLE(S) BEFORE THE DEFECT CONTRIBUTES TO AN UNNECESSARY INJURY OR DEATH. IN THE MEANTIME, WE DO NOT USE THE SCREEN IMAGE AT NIGHT. THANK YOU. *TR

THE CAR HAS BEEN IN THE SHOP A TOTAL OF 7 DAYS FOR THE SEATS NOT WORKING AND I HAVE YET TO GET IT RESOLVED. EMAILED THE CEO OF GM AND GOT A PHONE CALL FROM A PERSON WHO STATED GM CONSIDERS THE SEATS ARE WORKING ALTHOUGH THEY DON'T WORK MOST OF THE TIME AND WHEN THEY DO GET SOME SORT OF HEAT (THE SHOP TOLD ME THEY GOT ONE SEAT TO HEAT UP TO 87 DEGREES! WOW!) IT IS INTERMITTENT AND UNEVEN. THE SEATS HAVEN'T WORKED AT ALL IN THE LAST 3 WEEKS AND THE AVERAGE TEMP HASN'T BEEN ABOVE 32 DEGREES. I SPENT A FORTUNE FOR THIS CAR AND I CAN'T GET ANYONE AT THE DEALERSHIP NOR IN DETROIT TO ACKNOWLEDGE THIS CAR IS A LEMON OR THEY HAVE A DESIGN FLAW SINCE THEY SWITCHED TO BLOWERS FROM HEATED COILS. I AM SUPPOSING THE A/C IN THE SEATS WON'T WORK WHEN IT'S 100 OUTSIDE AND I'LL BE TOLD TO BE PATIENT AGAIN. I'VE ASKED FOR MY $$ BACK AND I'LL RETURN THE CAR. IT'S GOT 4,200K MI AND I AM SO DONE WITH THIS LEMON BUCKET. *TR

THE NEW 2015 VEHICLE FREEZES UP IN FULL TIME 4WD MODE AND WILL NOT SHIFT OUT. THE DEALER INDICATES THAT IT IS A "KNOWN PROBLEM BY GM" AND THAT THEY ARE "WORKING ON IT". THEIR FIX AT THIS POINT IS TO HAVE YOU RUN THE VEHICLE IN 2WD MODE WHICH IS AN OBVIOUS SAFETY ISSUE DURING OUR WINTER MONTHS AS IT IS THEN A REAR WHEEL DRIVE VEHICLE BEING DRIVEN ON ICY ROADS.THE OTHER FIX IS TO RUN IT IN 4WD MODE BUT TURN IT INTO 2WD MODE EVERY TIME YOU TURN THE VEHICLE OFF. OBVIOUSLY, MANY DRIVERS WILL FORGET TO DO THIS AND THEREFORE MY FAMILY AT TIMES IS JUST RUNNING IT IN 2WD MODE THEREBY INCURRING A RISKY DRIVING SITUATION. DESPITE NUMEROUS DISCUSSION, I HAVE NOT BEEN ABLE TO GET ANY INFORMATION ON WHEN THE VEHICLE WILL BE FIXED. *TR

VEHICLE HAS A TERRIBLE VIBRATION. HAS BEEN TO DEALER 7 TIMES, FOR A TOTAL OF 4 WEEKS. A GM ENGINEER HAS LOOKED AT IT TWICE. THEY HAVE REPLACED RING/PINION, DRIVESHAFT, AXLE .. TRIED IT WITH 4 SETS OF TIRES/WHEELS. LAST IDEA WAS TO REPLACE SHOCKS, STRUTS, SWAY BARS WITH HAND BUILT PARTS, CUT BRACKETS OFF CAR AND WELD NEW BRACKETS ON. WHEN LIABILITY WAS BROUGHT UP, THEY CHANGED THEIR STORY. THERE IS A LARGER ISSUE AS WAS RELAYED BY ENGINEER TO SERVICE MANAGER AT DEALERSHIP. ISSUE IS WITH ALL 2015 TAHOE, YUKON, ESCALADES. IN AN EFFORT TO PREVENT ROLL OVERS, THEY DESIGNED THE FRAME AND BODY MOUNTS TOO STIFF. THERE ARE 40 ENGINEERS WORKING ON ISSUES, THEY HAVE NO SOLUTIONS THAT WORK ACROSS THE BOARD. ACCORDING TO ENGINEER, GM IS KEEPING AN EYE ON HOW MANY UNITS THEY HAVE TO BUY BACK, OR TRADE FOR ... IF NUMBER IS LOW ENOUGH, THEY WILL NOT MAKE ANY CHANGES TO DESIGN. I WOULD LIKE TO SCHEDULE A MEETING NEXT WEEK TO DISCUSS THIS ISSUE AND THE LARGER ISSUE IN PERSON. SINCE THEY ARE REFUSING TO BUY BACK MY VEHICLE, I AM TURNING MATTER OVER TO ATTORNEY. *TR

ALL DOORS ON THE VEHICLE LOCK WHEN TRANSMISSION IS PUT INTO GEAR AND ALL DOORS LOCK SEVERAL SECONDS AFTER DOOR IS SHUT WITH ENGINE OFF. THE AUTOMATIC DOOR LOCKS CAN NOT BE DEACTIVATED BY MYSELF OR BY THE DEALER. I FIND THIS BOTH A SAFETY ISSUE AND A INCONVENIENCE. AS A COMMERCIAL TRUCK DRIVER DRIVEN MILLIONS OF MILES I HAVE BOTH WITNESSED AND HAVE DIRECTLY BEEN INVOLVED WITH TRYING TO GET PEOPLE EXTRACTED FROM WRECKS. DUE TO LOCKED DOORS IN SEVERAL CASES THIS HAS NOT BEEN POSSIBLE WITHOUT BREAKING A SIDE GLASS AND PHYSICALLY UNLOCKING THE DOOR FROM INSIDE OF THE VEHICLE. IN ONE ACCIDENT TWO PEOPLE WERE UNCONSCIOUS AFTER A CRASH WITH THE ENGINE RUNNING AND A FIRE UNDER THE HOOD, THE DOORS WERE LOCKED. IN ANOTHER, A PERSON WAS HAVING AN EPILEPTIC SEIZURE AFTER A CRASH AND AGAIN DOORS WERE LOCKS. IN THE LAST EXAMPLE A MAN DIED AFTER DRIVING INTO A CANAL, RESCUERS WERE UNABLE TO BREAK THE GLASS IN TIME TO SAVE THE DRIVER. I SHOULD HAVE THE ABILITY TO DECIDE WHETHER TO HAVE THE DOORS AUTOMATICALLY LOCK; NOT THE MANUFACTURER. THE 2013 AND OLDER GMC TRUCKS THE AUTOMATIC DOOR LOCKS CAN BE DEACTIVATED BUT 2014 AND NEWER GM REFUSED TO RELEASE THE PROGRAM TO THE DEALERS OR PUBLIC SO I HAVE NO OPTION BUT TO DRIVE WITH LOCKED DOORS. I AM ASKING TO HAVE GM RELEASE THE PROGRAM TO ACHIEVE DISABLING THE AUTOMATIC DOOR LOCKS. *TR

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.

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.

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.

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.
