2017 GMC Yukon

Defect. 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.

Defect. 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.

Defect. 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.

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 paint on my hood, roof and mirrors has peeled off and the gray coating is showing. I have own many GM vehicles and have never had this happen before.

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.

So the shock strut system up front has a grommet that holds it in. The repair order said they put a shock simulator in the car and it gave false reading saying it was good and it came out broke break line and caused me to jump a curve to stop the vehicle. ALSO Now the THE TAIL LIGHT IS OUT AND NO WAY TO REPAIR IT NO ONE HAS THE LIGHT. Also this car is on its third transmission

Engine blew at less than 80,000 miles

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 t

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 truck lost power while I was driving. Took to a shop and they found that a had a bad lifter. I have all of my service records from the GMC dealership where I had my vehicle serviced on a regular basis.

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.

Sitting at stop light engine began running rough and smoke coming out. CEL came on and began flashing, pulled over and had it towed. Diagnosis was PO300 misfire, dead miss on cylcinder 4, cylinder plug 4 is fuel fouled, cois is fine has good spark- caused by failed lifters. Needs engine replacement. Vehicle always serviced, garage kept and in mint condition with 89K miles.

The contact owns a 2017 GMC Yukon. The contact stated that the lifters were previously replaced in 2021 at the manufacturer's expense. Additionally, the contact stated that while driving at various speeds, the engine was running rough. The vehicle was taken to an unknown auto part store, where it was diagnosed with an engine cylinder malfunction. The vehicle was taken to an independent mechanic, where it was determined that the engine had experienced lifter failure or a more severe failure. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle needed to be diagnosed by the dealer, and that the manufacturer might help in covering the cost of the repair. The contact related the failure to NHTSA Action Number: EA25007 (Engine, Engine and Engine Cooling). The failure mileage was approximately 81,638.

At parking lot speeds, there have been many incedents of brake failure, when pressing pedal to stop pedal pulsates and becomes very hard to stop the yukon. there seems to be a vacume or booster issue. Yukon will be fine for days then reaccure when slowing at stop sign or waitng at red light and moving foward in slow traffic to sign or llight and then in happens again. scary and unreliable when using brakes at low speed intersections or continous stop and go's

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?

The contact own a 2017 GMC Yukon. The contact stated that the vehicle failed to shift from 2nd to 3rd gear while driving and remained stuck in gear. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and informed the contact that assistance would not be provided because the warranty had expired. The failure mileage was approximately 78,000.

WHEN I BOUGHT THE YUKON 3 YEARS AGO THE TRANMISSION WENT OUT WITHIN MONTHS, THEY REPLACED IT WITH A USED ONE, NOW IT IS STARTED TO DO THE SAME THING, IT WILL SLIP IN AND OUT OF GEAR, WHEN YOU GIVE IT GAS IT WILL JUMP INTO GEAR AT AN IDLE IT WILL DROP OUT OF GEAR, IT'S BEEN DOING THIS EVERY SINCE THEY PUT THE USED ONE IN, I NOITIED THEM THEY SAID THAT IT IS NORMAL???? I HAD THE WORK DONE @ PAHRUMP VALLEY AUTO PLAZA. I'M AFRAID THAT WHEN IM AT A LIGHT IT WILL NOT GO INTO GEAR AND I WILL GET HIT. NO WARING LAMPS CAME ON AT ALL, IT HAS PROGRESSIVELY GOTTEN WORSE.

THE BRAKE LIGHT IS OUT AND A SINGLE TAIL LIGHT IS OVER 500$ Very dangerous to have tail light out and can cause an accident. There should be a recall on these defective LED lights.

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.

The contact owns a 2017 GMC Yukon. The contact noticed that the chrome on the rims of the vehicle was oxidized. The vehicle was taken to an independent mechanic who replaced the rims. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

At low idle speeds like in a parking lot we almost hit another car because the brakes were very hard to press. No power brakes. Felt as I was having to stand on the brake pedal with both feet to stop my vehicle from hitting another car at a grocery store parking lot going 5 mph! A light flashes on and says”service brake assist “ light goes away and drives normal and brakes normal except when you get to a stop sign, or traffic light. This happens a few times and I’m not driving the car because of it because I might hit someone

Yukon break tail lamp problems. Brake lights work intermittently. Very dangerous! The break lights will work intermittently and then work. This was an issue with the 2016 models and GM issues a recall. There is no recall for 2017 which I don't understand because nothing has changed with the manufacturing process. I researched and there is a class action but in California only.

Full engine failure

116k miles and the transmission went out. Spent almost 6k on a jasper to replace it. I don’t think I need to explain what happens when a trans goes out. It did all of those things.

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.

The information screen on the gauge cluster sometimes will stop working. This is dangerous as It is the only part that shows if the vehicle is in Park, Reverse, Nuetral, or drive. It also is the only part that shows the vehicles fuel level, blinker, cruise control, temperature and other warnings and controls. This is a common problem for the 2015- xxxx Yukon and Tahoe.

Engine Failure while driving, almost causing me to wreck on the highway.

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

[XXX] Please call me to discuss this matter on my GMC Vehicle. [XXX] Yukon GMC This might not be your department but lead me to the right area local, federally or NHTSA so I can discuss these issues in detail Issues I have had that are not normal and maybe need to be on a recall or on consumer alert list for major defects on major components Brakes losing total traction had to be fixed unannounced (recall) Rear Tail lights giving up , had to be replace (Recall) AC system failing had to be replaced Paint completely fading on hood prematurely Transmission failure, had to be overhauled Engine Failure with need of Lifters All the above high cost to fix and having no vehicle in the interim .

Magneride defect - struts leaking !!! 85,000 miles This is unacceptable- car is dangerous- bouncing - rough ride- shaky- jerking Should be a recalll! Look it up online- many many complaints!

The contact owns a 2017 GMC Yukon. The contact stated upon starting the vehicle, and while driving at various speeds, there was an abnormal ticking sound coming from the engine. There was no warning light illuminated. The contact stated that the abnormal ticking sound had gotten louder. The vehicle was taken to the dealer, and to several independent mechanics; however, the cause of the failure could not be determined. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 181,000.

The vehicle main information cluster randomly goes in and out and now has completely stopped working. This is the information display that shows Park, Nuetral, Drive, Reverse, Fuel gauge, digital MPH and other information such as oil tire pressure, turn signals, forward collision. Just knowing if the vehicle is in Park Reverse or Drive is a huge saftey issue. This seems to be a common problem on GM vehicles and i wcan't seem to find a recall issued for the saftey factor that the vehicle can be assumed to be in Park and it's actually in Reverse. The first time I noticed this problem was Sept. 05, 2020 but it had reset when I restarted the vehicle. The problem would resurface occasionally but always came back on when restarting the vehicle. But know it seems that restarting the vehicle is not fixing the problem and the screen has been blank for the last 3 days.

The air condition lines that feed the rear compartment of the vehicle rub above the rear tire and put a hole in the line. The cost to replace was $2,000. Bad design

Transmission went out in August of 2023, had to have it rebuilt and costed 9,000. Safety was put at risk due to car sputtering to shift gears on the highway while traveling. Problem was identified by the dealership. No light indicators were on. Vehicle now has engine starting to come on periodically and when trying to diagnose it is giving fuel efficiency codes.

According to dealership Front and Back Suspension - SHOCK &/OR Struts - According to all complaints online it could be the Magnetic Ride Control- Car is a danger!!!!!! This car bounces all over the place - rides rough and bumpy!!! This should not be happening at 84K miles!

Lifters failed

Brake pedal gets hard and will not allow vehicle to stop. Intermittent issue, but caused vehicle to hit gate. Same situation occurred later that same week and vehicle almost rolled through major highway crossing.

RPM’s started to fluctuate while driving with cruise on. Noticed no issue with shifting until torque converter grenaded blowing metal through the transmission 2 days later. Transmission has been replaced with GM reman by a GM dealer. New transmission lags going into gear when it’s cold and shifts hard. GM tech said this is common and no way to correct it without replacing it again.

Transmission jerks, shifts hard, loses power… Temp gets 199 just driving… Humming sounds, taken to dealer three time… 188,000 miles…

The pump in the power-assist brakes puts out less vacuum power than needed, increasing stopping distance and the risk of a crash. My car rolls and doesn't stop. I have new brakes so this is unacceptable!!

High pressure fuel pump regulator failed and cause gas leaking, reduced engine power and gas smell coming back in vehicle. It was also blowing out white smoke. It had delayed ignition starting. The engine light did come on. Several makes and models of GMC has had recalls for this problem. The 2017 GMC Yukon was not included for this recall and should have been.

My transmission does not engage properly. From a starting position when I step on the gas the transmission lags and when it catches it slams / bangs into gear

Clutch in Torque Converter failed at just around 60,000 miles. Vehicle had a vibration issue shortly before & I thought maybe I got a poor quality tank of gas. Filled up with new gas and problem still there. Took it to my mechanic & he told me it was a complete failure which would require a new transmission or a rebuild on existing.

I have a 2017 Yukon. There is a recall on this model already for a vacuum pump that decreases the power brake assist. My vehicle is having this exact issue. The back tire sounds like the compressor is always running and when braking it grinds at the pedal like a vibration and doesn’t want to stop immediately. I need my vehicle added to the recall list so I can get it repaired.

I bought the vehicle in October 2024 ever since then I have been trouble with the differential, the automatic starter doesn't start the vehicle unless you are at least one feet away from the vehicle. I drove to work when I got off and got in my vehicle my check engine light was on. The vehicle was saying there was an issue with the battery, antilock braking system. I bought an extended warranty up to 150,000, I currently have 63,400 on my vehicle. Empire Buick GMC of White Plains has not been honoring my warrantee, I had to rent a car to get back and forth to work because of fear of riding the NYC subway.

The contact owns a 2017 GMC Yukon. The contact stated that while depressing the brake pedal, the driver’s and passenger’s side taillights failed to illuminate as designed. The contact called the dealer about the failure and was informed that there were no recalls or warranties on the vehicle associated with the failure. The contact was also informed that the repair would be an out-of-pocket expense. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 64,000.

I was driving my car and it started making "clanging" and "banging" noises and jolting/jerking forward. It was scary to drive because of the noise and the jerking foward. I was afraid that my car was going to just stop working, I would get stuck/stranded somewhere or my car was going to blow up. I brought it in to the dealer two times. The first time they thought it was the battery so they replaced the battery but that didn't fix the problem. The second time I left it there for days and they told me that I needed a new transmission. The problem was reproduced and inspected by them. There were no warning lights or messages prior to the failure. The problem started on approximately January 6, 2025. Online, I have read from other sources that 2017 - 2020 GMC YUKONS are know to have transmission problems. My car only has 58,000 miles on it, has been serviced consistently, and should not need a new transmission at this low mileage point.( 150,000 to 200,000 is the norm for transmission replacement)

Not even 100,000 miles on it and the engine blew. Started with a lifter issue. Everyone I talk to with Yukons and GMC in general say it’s a problem. Just a search on the internet shows that they all have this issue… a well maintained car should not have this issue and it’s clearly a GMC issue and it needs to be fixed. The repair shop can’t even order me a new engine due to this being a real problem all over with GMC.
