2017 GMC YUKON Power Train Problems

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.

Mileage: 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.

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.

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.

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

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.

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…

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.

Transmission shutter causes the car to vibrate which could lead to transmission failure.

The contact owns a 2017 GMC Yukon. The contact stated that after starting the vehicle, the vehicle was vibrating abnormally. The front of the vehicle was shaking. The contact stated that while at a stoplight with the brake pedal depressed, the vehicle stalled but independently restarted. The engine warning light flashed on and off. The vehicle was taken to the local dealer, where it was diagnosed with transmission and engine failure. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and confirmed there were no recalls on the VIN related to the failure. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 50,000.

Vehicle Malfunction Incident Report On [11/2724], while stopped at a traffic light, the vehicle experienced a sudden and significant loss of power and gear shifting capabilities. The engine accelerated, but the vehicle struggled to move and shift gears, making it difficult to cross the intersection. After a short distance, the vehicle accelerated again, but there was no forward movement. The vehicle was subsequently parked in a nearby neighborhood, where it became completely immobile. Attempts to engage reverse or drive were unsuccessful. The vehicle emitted a loud noise, and a check of the transmission fluid and other fluids revealed no issues. After turning the engine off and restarting, the vehicle was able to engage drive, but it was limited to second gear. The vehicle then lost momentum again, making it difficult to reach home. It is important to note that no engine light illuminated during the incident, and there were no visible fluid leaks. All routine maintenance has been performed according to the manufacturer's recommendations. A mechanic has inspected the vehicle and diagnosed potential transmission issues. Requested Action: We request a thorough investigation into the cause of this malfunction. We believe that a transmission issue is the likely culprit, but further diagnostic testing is necessary to confirm the exact problem. We have seen that this has been a reported issues with these vehicle and the manufacture has not done anything for recalls.

I was taking my client to school. I stopped at the stop sign. When I pushed gas pedal to go, my truck did not go, it strained did a big jerk then went. The next morning it did the same thing & later on that day, it did it again. Two days later I had to stop at red light. When the light turned green I pressed the gas pedal & nothing. It did not go at all. I turned the ignition off and back on twice & put it in drive still did not go but was slowly going backwards. A by-stander stopped to assist me getting my truck out of traffic.

Transmission failed on the freeway with no signs signaling issue before hand at 109,000 miles. Also lane departure does not work often. And suspension gave out at 60,000 miles.

The contact owns a 2017 GMC Yukon. The contact stated while driving at various speeds, the vehicle started jerking and hesitating while shifting gear. The vehicle was taken to the local dealer to be diagnosed and the contact was informed that the transmission was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 140,000.

Tremendous transmission shudder prevented me from properly accelerating from a stop light thereby causing a dangerous traffic backup issue in a congested area.

I was stopped at a red light in the left hand turning lane and when the light turned green I proceeded to accelerate and the engine would rev but the car would not move forward so I continued to push on the gas when the car jolted forward Violently. I am lucky no one was in front of me because this would have cause a car accident. Turns out the transmission had failed and needed to be replaced which is a common issue for GM however they never owned up to it and refused to pay to for the cost of the replacement and I paid several thousands out of pocket. This is a major safety concern and could be potentially life threatening. GM should recognize this as a recall and take ownership of a failed transmission with less than 100,000 miles.

Tail lights went out. Lifters have been replaced TWICE! While stopped at red light, at take off the vehicles lunges forward. At low speed the vehicle will down shift on it’s own. 80k miles Recently while headed to work, the torque converter went out. 126k This is suppose to be a luxury vehicle and cost entirely to much to be a POS. I honestly thought I had a lemon but it seems to be a reoccurring issue in the entire fleet.

The SUV was stalled after getting in D to drove forward and all of a sudden it’s started with a big jerk and moved forward It went driving ok for them rest of the day but it kept repeating the incident n and off until June 15 when it was stalled on a traffic light I was able to put the emergency flashers and drive it in reverse to a near by parking lot

Tranny failed at 92k miles even though properly maintained. Since new tranny installed by dealer (out of pocket cost) had to return due to tranny slipping into neutral when driving highway speeds and taking foot off gas. Dealer performed TCM and ECM flash updates. Cost out of pocket for programming. Issue came back less than 2000 miles later

Transmission /torque converter I was driving on highway and all of a sudden what seemed like the engine lost power and I could not accelerate. After heading to slow lane and few seconds later everything went back to normal. A week later same thing happened but this time it wouldn’t shift to second gear. I was stranded on side of road. Before calling help , I let it idle for a few minutes and tried again to put in drive, it worked again. I made it home. Next day it just started making a loud noise under truck. Was able to get a mechanic and he said it’s the transmission. Has 103k miles and is out of warranty

At traffic light in drive position, shifting drags when accelerated and hard shift jerk , slipping gears or driving and not shifting at all

The transmission was jerking jumping and was replaced under warranty and it still can not be fixed. Cause the vehicle to jump backward and hard speed.

First problem started back in May.. it’s went downhill ever since. Hard shifting was happening. GM dealer said I needed a new transmission. Found out from local repair shop that I needed a torque converter ($600) multiple transmission fluid changes (apparently many issues for A Lot of people) changed that. Then had to change Valve Body & TCM. ($540) everything started working but not 100% did a full tune up having multiple misfires constantly then shuttering when idle. Also replaced ECM ($200+)After changing all spark plugs, wires, oil, etc. the AC was having issues had been having issues for months. Kept adding Freon had to replace AC Condenser (works great now, was told by repair shop that’s also very common in these year models. Condensers are all weak in the same spot) just recently October 2022, my instrument cluster started going haywire. Gauges going off and on screens going blank. Had Alternator and battery tested both test fine. No loss of power but when hitting the start/stop vehicle would continue to run and lock and unlock when it wanted. Husband took the alternator out to have it tested again. They tested 3x 1st. Good, 2nd Error, 3rd Bad ( it was overcharging at 16.5V) replaced Alternator ($290) gauges still going haywire, like before it is only sometimes, when they do it’s bad bad.. but I can also drive to town and back 20-30 miles and not the first issue. Just left GM with a new Battery Distribution Fuse Block ($153) because of course it can’t just be a regular ($8-10) mega fuse, hopefully this will fix my issue. We pay too much money for this vehicle to have all of these issues & none be under warranty. I’ve been having the TAILLIGHT ISSUES as well ever since I purchased the car in 2018. When I received the recall on the taillight it was 6 years up to 72,000 & of course my vehicle had 79k miles on it at that time so that’s wasn’t covered.

My vehicle began shuddering during acceleration and would violently jerk forward after gas pedal was engaged with decreased power in forward acceleration and increase in rpm. This last a couple of weeks. Now, my vehicle is completely broke down and at a GM certified service center. The Service manager states torque converter completely went out and the transmission is burnt up. The mileage is at $61,000, so GM warranty won’t cover it and the company that holds the extended warranty I purchased hasn’t been able to be successfully contacted. There is a “service” bulletin but no recalls and a class action lawsuit (that I’m not a part of) but no recall. My vehicle completely lost power going 50mph on a busy road without warning. This needs to be a recall due to this dangerous circumstance.

The transmission failed while merging and almost caused a collision. After a complete transmission replacement, the fuel injectors failed causing the same issue. GM extended fuel injector warranty due to the number of similar issues, but not in my state.

My car is not shifting right. I took it into GMC, and they said they corrected it. I have taken in two times for this issue already. Today I almost was in a car accident because the car would not shift properly and it shoved me forward like A car hit me from the back. The car is not shifting properly at all. And now it’s making a muffling sound and it’s like stuck in a gear. I pulled over and I parked and then I reversed and then I went to hit the gas again to try to go slowly and it jolted forward again. This is serious and needs repaie

WHEN TRAVELING AT LOW SPEEDS (10-20 MPH), I HAVE CONTINUOUSLY EXPERIENCED "LUNGING" AND "JERKINESS" WITH MY TRANSMISSION FOR OVER 2 YEARS NOW. DESPITE APPROXIMATELY A DOZEN SEPARATE EVALUATIONS AND/OR REPAIRS BY GM-CERTIFIED TECHNICIANS, THE PROBLEM CONTINUES TO EXIST. I AM TOLD THAT THE ISSUE IS NORMAL AND THAT I MUST LIVE WITH THE ISSUE AS BEING NORMAL. NOT ONLY AM I CONCERNED ABOUT THE ONGOING MAINTENANCE COST, BUT THE SAFETY OF MYSELF AND PASSENGERS SHOULD THE VEHICLE STRIKE AN OBJECT OR PERSON ACCIDENTALLY. ACCORDING TO VARIOUS ONLINE SOURCES, THERE ARE HUNDREDS OF GM OWNERS WHO ARE EXPERIENCING SIMILAR ISSUES, AND EVEN A CLASS ACTION LAW SUIT HAS BEEN FILED. HOWEVER, THERE HAS BEEN NO ACKNOWLEDGEMENT OR MEANINGFUL RESOLUTION TO THE PROBLEMS.

Mileage: 31,000

MY 2017 GMC YUKON DENALI CONTINUES TO HAVE A VERY LOUD SHUDDER SOUND AS YOU ACCELERATE.

VEHICLE HAS HARD SHIFT FROM PARK. MOST OFTEN WHEN FIRST DRIVEN OF THE DAY BUT ALSO OCCURS WHEN STOPPING FOR REDLIGHTS OR STOP SIGNS WHILE TRAVELING.

Mileage: 48,000

BEGINNING AROUND 56,000 MILES THE TRANSMISSION STARTED LURCHING AND STUTTERING AT SLOW SPEEDS. IT IS WORSE WHEN COLD BUT NEVER QUITE GOES AWAY. DEALERSHIP KEPT IT FOR 3 DAYS AND FELT IT BUT SAID ALL WAS WITHIN NORMAL RANGE. BEGINNING AROUND 65,000 IT STARTED STUTTERING WHEN TRYING TO ACCELERATE WHILE IN MOTION, SUCH AS ON THE HIGHWAY WHEN TRYING TO PASS. THIS IS NOT ONLY ANNOYING BUT DANGEROUS WHEN YOU CAN'T GET THE POWER YOU NEED WHEN NEEDED BECAUSE THE TRANSMISSION CAN'T DECIDE WHEN TO SHIFT.

Mileage: 56,000

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE ATTEMPTING TO PULL OUT INTO TRAFFIC, THE TRANSMISSION SUDDENLY SLIPPED AND THE VEHICLE MADE A HIGH PITCHED HUMMING SOUND. THE CONTACT TOOK THE VEHICLE TO HILTON HEAD BUICK GMC CADILLAC (LOCATED AT 1090 FORDING ISLAND RD, BLUFFTON, SC 29910, 843-815-1500) WHERE IT WAS DIAGNOSED THAT THE TORQUE CONVERTER NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED BECAUSE THE DEALER WAS UNABLE TO GET THE PART FROM THE MANUFACTURER. THE DEALER WAS UNABLE TO GET CONFIRMATION AS TO WHEN THE PART WOULD BE PROVIDED. THE CONTACT ATTEMPTED TO CALL THE MANUFACTURER, BUT WAS UNABLE TO SPEAK WITH ANYONE. THE APPROXIMATE FAILURE MILEAGE WAS 96,700.

Mileage: 96,700

FROM TIME TO TIME THE VEHICLE LUNGES FORWARD WHEN IM STOPPED AT A STOP SIGN, CROSSWALK OR A STOP SIGN. I HAVE HAD IT INTO THE DEALERSHIPS NUMEROUS TIMES BUT GM ONLY WANTS TO PUT BANDAIDS ON THE ISSUE, GM HAS A MAJOR ISSUE WITH THEIR EIGHT SPEED TRANSMISSION, THEY ONLY HAVE INTERNAL BULLETINS TO THEIR DEALERSHIPS. THE DEALERSHIP TELLS YOU TO BRING THE VEHICLE IN AND THEY WILL DRIVE IT WITH THE CUSTOMER, BUT THE ISSUE IS INTERMITTENT AND DOESNT ALWAYS LUNGES, GM IS TRYING TO OUTLAST THE CUSTOMERS HOPING THEY WILL GET TIRED OF DEALING WITH THE ISSUE AND THEY WILL GO AWAY. GM CANNOT AFFORD A RECALL BECAUSE OF THE SIZE OF THE PROBLEM, SEVERAL DEATHS WILL OCCUR UNTIL THIS ISSUE IS RESOLVED. THE ISSUE HAPPENS ON THE ROADWAYS

WHILE DRIVING AT SLOW SPEEDS THE TRANSMISSION WILL SUDDENLY SHIFT EXTREMELY HARD INTO FIRST GEAR WHEN WHILE LIGHTLY INCREASING SPEED. THE TRANSMISSION WILL SHIFT EXTREMELY HARD INTO FIRST GEAR WHILE GRADUALLY COMING TO A STOP. OCCASIONALLY WHILE DRIVING SLOWLY (PARKING LOTS) THE TRANSMISSION UPSHIFTS TO SECOND GEAR CAUSING THE CAR TO LURCH FORWARD NEARLY CAUSING A COLLISION. THIS IS A CONTINUING PROBLEM THAT CANNOT BE REPAIRED AT THE DEALERSHIP.

Mileage: 5,000

I PURCHASED MY 2017 YUKON DENALI IN 2017. SINCE THE DAY I BOUGHT IT I HAVE NOTICED A PROBLEM WITH APPEARS TO BE THE TRANSMISSION. I WILL BE AT A STOP THEN I ACCELERATE AND THE CAR HAS A HARD SHIFT FORWARD. IT TENDS TO PULL FORWARD ALL OF A SUDDEN BUT VERY VIOLENTLY. I HAVE TAKEN IN MY YUKON TO THE TWO GMC DELERSHIPS IN MY AREA SEVERAL TIMES. THEY HAVE SERVICED IT AND EVEN PERFORMED A TRANSMISSION FLUSH BUT STILL THE PROBLEM HAS ALWAYS CONTINUED. I HAVE BEEN DEALING WITH THIS YUKON PROBLEM FOR TWO YEARS NOW. ITS SO DANGEROUS TO DRIVE.

Mileage: 100

I HAVE TAKEN IT IN TO THE DEALERSHIP SEVERAL TIME FOR INSPECTION. THE FIRST TIME INVOLVED A REPEATED VIBRATION WHILE DRIVING. THE RESOLUTION WAS TO CHANGE OR FLUSH THE TRANSMISSION FLUID TO GET RID OF ANY METAL SHAVINGS. SINCE THEN I'VE TAKEN IT BACK INTO THE DEALERSHIP TWICE WITH REPORTS OF JERKING, A DELAYED START WHEN ACCELERATING, AND MOST RECENTLY A LURCHING WHEN SHIFTING BETWEEN REVERSE AND DRIVE. EACH TIME THEY HAVE SAID THIS IS NORMAL.

Mileage: 24,000

THE TRANSMISSION OR TORQUE CONVERTER ARE SHUDDERING HOW DO WE FIX, HOW DO I PROTECT FAMILY, WILL THE TRANSMISSION FALL OUT ON HIGHWAY CAN I KEEP DRIVING AND BE SAFETY WITH FAMILY?

Mileage: 9,000

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 THE YOUR BACK BUMPER. IT IS ALSO BAD ENOUGH THAT IT STARTLES THE DRIVER AND COULD BE A SAFETY ISSUE. GM IS SAYING THAT THIS IS NORMAL FOR THIS EIGHT SPEED TRANSMISSION. IF MY CAR, THE ONE I'M DRIVING NOW, HAD THIS SAME PROBLEM I WOULD DEFINITELY REPLACE THE TRANSMISSION. THIS IS A 2017 DENALI WITH LESS THAN 5000 MILES ON IT. ONLINE THERE ARE MANY COMPLAINTS ABOUT THIS AND IT SEEMS THAT GM IS TRYING TO WAIT THE PUBLIC OUT NOW THAT THE NEW VEHICLES HAVE A NEW TEN SPEED TRANSMISSION. THE DEALER TOLD ME THEY COULD NOT FIX THE PROBLEM AND WE WOULD HAVE TO LIVE WITH IT. AGAIN, THIS TO ME IS A MAJOR SAFETY ISSUE.

Mileage: 4,400
