The daylight running light in the rear do not work, which is needed for night time driving. At night when parked or driving the rear is completely dark, except the license plate lights. When I press the brakes they turn on, the signal lights work even the reverse lights. I've switched them to manual mode still no luck. I've checked some fuses, they all check out, nothing blowen. From some research it's all conctrolled by the body control module. There are alot of cars with this same issue there should be a recall for gm to fix properly, dues to safety of the driver and public. We just bought this vehicle which, and didnt test drive at night. 3 days later we discovered it. We even bought new lights due to the number of complaints. They still don't work.

There has been 3 different incidents. First incident I was going 45mph merging into 5 lanes of traffic when the back of my driver seat randomly layed down flat and stayed there. I had to get off an exit, get out pull up on front of seat and then it layed back up. 2nd incident I was going about 40mph it folded completely forward and pinned me against the steeling wheel. I had to stop immediately in the middle of the road put my 4 ways on and wiggle and slide out of the car started pulling up on front of seat and was finally able to put it back in place. The 3rd time I was going 20 mph it folded completely forward and pinned against. Had to stop in the middle Of the road again pull up on front of seat. The lumbar setting randomly comes and goes while driving down the road. Took it the garage to be looked at. They weren’t able to figure out why it’s doing what it’s doing but the only option they had was to unplug the module for safety reasons

The recall repair for the brake vacuum pump did not hold for this vehicle. Even after the repair, several years later, the brakes would get hard as a rock, especially at low speeds and there was difficult stopping the vehicle. Due to the special Warranty on this recall, I was able to get the brake vacuum pump replaced at no cost. However, the recall repair failed initially. This is a safety issue.

Passenger brake Led Circuit board prematurely failed resulting in the entire assembly needing replacement. The assembly is $500 and higher. This is a safety issue and though there was a class action lawsuit, the light fails after 72000 miles which appears to be when GMC wont replace the part. $500 for a tail light replacement is a financial burden to be able to keep the car on the road. There is no warning when the light fails. Please consider a recall on the tail lights.

My engine starting making a knocking/ticking noise out of no where. I was traveling alone on the highway so I stopped to check it. I got to a gas station and google searched it and it came up that the LS 6.2 engine that is in my vehicle was recalled on other models because of this issue. I did have a mechanic look at it as well and he agreed it is that same issue that was recalled in other models.

The 2017 GMC Yukon has serious transmission issues that GM continues to ignore, and it is going to get someone hurt. I was stopped at a red light, and when it turned green, I pressed the gas pedal but the car would not move. I pressed harder, and then it suddenly lurched forward about 30 feet. If there had been a car in front of me, I would have hit them and likely caused injuries. When I took it to the dealership, they said it needed a full transmission replacement, which was not covered. I had to pay out of pocket. I was only about $10,000 outside the warranty when it failed, and GM refused to stand behind their product or help in any way. I was already financing the vehicle and should not have had to pay for a new transmission on a car that was less than four years old with relatively low miles. This is not just my experience. Many others have had the same issue. GM knows about it and chooses not to acknowledge it. They are lucky no one has been seriously injured or killed because of it. Going to attach all of the proof of people "coincidentally" experiencing the same issue.

The 8-speed automatic transmission (Hydra-Matic 8L90) on this 2017 GMC Yukon SLT 5.3L V8 has failed. This is a repeat failure — the transmission was previously rebuilt in 2020 under a GM recall/service action for the same known defect affecting this transmission type. The transmission has now failed again in 2026, approximately six years after GM's prior repair. Prior to failure, the vehicle exhibited hard shifting, shuddering during acceleration, and hesitation between gear changes — symptoms consistent with the known defect pattern documented across 2015–2019 GM vehicles equipped with this transmission. The failure was confirmed by a service center. The vehicle is currently not safely drivable. Safety concern: erratic and unpredictable gear changes, including sudden lurching and hesitation during acceleration, create a dangerous condition for the driver, passengers, and other vehicles on the road. GM has been contacted through their Customer Assistance Center (case opened). GM's initial position was that they cannot assist because the vehicle is out of warranty. However, this is a repeat failure of a previously repaired known defect. GM issued 13+ technical service bulletins on this transmission and has been aware of the root defect since at least 2018. A federal class action (Speerly v. General Motors, E.D. Michigan) covering this exact vehicle type and transmission has been certified and upheld by the Sixth Circuit Court of Appeals. The prior GM repair did not remediate the underlying defect.

Slipping Gears: Many Yukon Denali owners report experiencing unexpected gear changes or loss of power while driving. Hard Shifting: This problem manifests as harsh or abrupt gear changes, often accompanied by noticeable jolts when shifting from one gear to another. Unusual Noises: Grinding, whining, or clunking sounds when shifting There has been a class action lawsuit for this. I'm not sure why it has not been recalled in all states.

This has been going on for a while now, but it’s getting worse overtime. If I push on my brakes more than twice the brake pedal locks up and I have to push extremely hard to get my vehicle stopped.. luckily I have never been going fast and had to worry about this. This is normally when I am pulling into a parking spot or I am backing up that I have to tap on my brakes a few times. A couple of times I have bumped the pole in front of my parking spot due to not having brakes. I just put in a general date as to when they started to get worse.

I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC garage have them put it on a machine, and I was told that it needed a new transmission and this wasn’t something GMC was covering. This new transmission cost me $6200 and was done on 1/5/25. Please remember this vehicle only had 64,000 miles on it, which is absolutely ridiculous to need a transmission at this mileage. I again had called in January 2025 reporting this and was told someone would call me back and never heard from them.

On July 3, 2025 we were traveling on a 4 lane at 55mph. Without any prior symptoms, the vehicle began to shake violently. It shook so hard that the skid warning light simultaneously came on. It was followed by the check engine light. The oil pressure guage started bouncing around. We stopped driving the vehicle and had it towed to VanYork GMC dealer in Asheboro, NC on this same day. (Invoice attached) VanYork GMC determined that cyclinder 5 was misfiring. We paid to have them repair it, and we began driving the vehicle again. (invoice attached) On or about August 1, 2025 we were traveling on an interstate at 70mph. Without any forewarning, the vehicle began to violently shake. Just as before, the skid warning light simultaneously came on, followed by the check engine light came on, and then the oil pressure guage started bouncing around. As there was heavy traffic on the interstate, the failure created a very dangerous situation for us as we tried to maintain our lane, and stay in control of the vehicle until which time we were able to safely maneuver to the side of the road. The vehicle was again towed to Vann York GMC in Asheboro, NC. (invoice attached) On December 3, 2025 we received a call from VannYork GMC saying that the vehicle repairs were complete. It had been in their repair shop for 4 months. This repair began with lifter and camshaft replacement. When this repair was unsuccessful, they decided that the vehicle needed a 'new' rebuilt engine. Since GMC has not offered any assistance with the expense of this new re-built engine, we will have to satisfy the $12,000 bill when we pick it up. After experiencing two very dangerous episodes, we are happy that we did not wreck, but certainly, this not the situation we expected from a high-end vehicle with only 76,169 miles on it.

At stop light vehicle began to sputter and make noise, I was very close to my home, no engine light on. Upon turning vehicle off and using a code reader codes P0106 and P0506 was on scanner. I had vehicle towed to Complete Car Care. Mis fire on multiple cylinders. Vehicle has 69,801 miles. 3 push rods bent and I valve spring broken. The right Cylinder head assembly had to be removed and replaced with 8 new push rods, 8 new lifters, gaskets, seals, and valve spring. Cost was 3304.79. In addition the rear tail light has been sporadic on and off, GM was to replace up to 70,000 miles. When I took it to them they stated the time limit had expired, yet I had not been informed until I did a google search. GM requesting 475 plus tax. I am concerned my vehicle has the same manufacturing defects as the GM motors being recalled with total engine failures.

We noticed the passenger side taillight was out. It’s not a simple bulb replacement but an entire assembly. It was put back in place and it lit up again. A few weeks later it wasn’t working. Pounded and tapped on it and it works again. We're guessing there is some sort of short so we asked for an estimate on getting an assembly replacement when it was in for a regular oil change. Shocked that a necessary part would cost $1,112.77!!! Whatever happened to changing a bulb for a few dollars?

I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened.

I was stopped at a traffic light and was informed by another driver that my right tail lamp was not working. There were no warning lights indicating that there was a problem. When I arrived home, it began working after I tapped on it. A few days later, the left tail lamp stopped working. I began to realize that both tail lamps were only working intermittently. Upon inspection by the mechanic, I was informed that this is a common problem with my vehicle and that each replacement part is approximately $900, totaling nearly $2,000 to replace both lamps. This is an obvious safety hazard for myself and for others who may not be able to judge when I am stopping, especially if I have to stop suddenly.

My transmission failed again after being replaced by General Motors certified dealership. The transmission in question has failed again after less than five months being back in service. In 2024 and 2025 my vehicle has been in and out of the service department at other dealerships and they cannot repair the vehicle according to the dealerships they do not have the staff for it. General motors will not stand behind the transmission as they have now labeled it as a part so they will not have to provide transportation. According to dealerships in my area in Michigan, they do not have the staff or the parts to service my vehicle. I contacted General motors customer service multiple times regarding the situation. We truly have a bad transmission again in my vehicle. The transmission in question is a C8 transmission that has failed due to shuttering and downshifting, which the replacement remanufactured transmission for $8000 continues to fail. General motors will not buy back this vehicle or address this ongoing issue. I truly believe I am not the only person with transmission issues as this is a major defect by the manufacturer, which is General Motors. Will you please look into my complaint is this is caused severe hardship to my family. General Motors needs to take responsibility for this failure to the transmission. I’ve had seven other items that have failed also on this vehicle, including the engine. Thank you for your time and consideration looking into this matter. Sincerely [XXX] .

In May 2025, my vehicle suddenly started jerking, shaking, and almost stalled out while driving. I was on a busy 3 lane roadway with 6 passengers total. As I would try to accelerate, the power was significantly decreased. I felt it jerk between shifting several times. My check engine light came on. I was so scared that someone would hit my vehicle and injure us. I brought it to a GMC dealership. They said that my transmission failed, metal in the transmission fluid. How is this possible? Upon researching this problem, this is a common issue with the 2017 GMC Yukon Denali. There are class action law suits and lemon law lawsuits against GMC regarding this problem which causes major safety concerns. My vehicle has been well maintained with lots of service records to prove it. I have babied her and I’ve never towed anything. This transmission issue needs to be addressed and recalled. I need a new transmission which will cost between $5,000-$7,000. This is just horrible and disappointing regarding the quality and reported issues that are not being recalled by GMC.

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.

Risk: 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.

General Motors LLC (GM) is recalling certain model year 2015-2017 Chevrolet Silverado 2500 HD, 3500 HD, Tahoe, Suburban, GMC Sierra 2500 HD and 3500 HD, GMC Yukon, GMC Yukon XL, Cadillac Escalade and Cadillac Escalade ESV vehicles and 2014-2017 Chevrolet Corvette, Silverado 1500, Trax, Caprice Police Pursuit Vehicle, GMC Sierra 1500, Buick Encore, and 2014-2016 Buick Lacrosse, Chevrolet Spark EV and SS vehicles. In the affected vehicles, 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.

Risk: 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 October 13, 2016. 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. GM's number for this recall is 16007.

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.

Risk: 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.
