While traveling at highway speeds, my 2017 GMC Yukon SLE suffered a sudden, catastrophic Active Fuel Management (AFM) valvetrain lifter and camshaft collapse. This caused an immediate and highly dangerous loss of vehicle propulsion in live moving traffic on I-95, creating an extreme physical safety hazard for my family. General Motors has extensive, documented internal corporate knowledge of this severe design defect under Technical Service Bulletin TSB #18-NA-073.

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.

My vehicle started making a knocking sound and eventually died on me. 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. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

I brought a 2017 Yukon GMC from a dealership. When I first drove it on a highway it began to pull and shake, to the point it slow down on the highway. Also the dashboard started to shake , vibrate on the highway. When I step on the gas on a local road ,the transmission is pulling to pick up speed. Took it to a Mechanic and explained to him what was going on he test drove it and told me it's the transmission. He also said this year truck " GMC" truck like this has bad transmission. I did my research and find out that it is true. I have a disabled mother that I take to her doctors appointment and I'm scared bto out her in this truck. This is a 1 vehicle and anytime the truck will just slow down or vibrate or shake. No check engine light comes on when it happens.ifni driving on A highway sometimes the check engine light will blink 3 to four times then go back out.

My 2017 GMC Yukon SLT,, has been having shifting problems, including hard or delayed shifts, clunking, jerking, and even sudden jolts when downshifting.Rough or jerky shifts, particularly during acceleration and deceleration, a delay in engaging gears, especially when shifting from park to drive or reverse. Transmission shifts are very rough in slow traffic with as much as one to two-second delays in shifting into gear with a loud thump. It is so rough that it feels like someone may have ran into your back bumper. It is also bad enough that it startles the driver, and it could be a safety issue

Official recalls

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.
