general problems of the 2017 GMC Yukon - part 1

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.

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.

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.

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.

At stop light vehicle began to sputter, run rough, and make noise. I was less than a mile from my home, no check engine light on. I turned the vehicle off, used a scanner to have codes p0106 and p0506 show. I had vehicle towed to complete car care. Misfire on multiple cylinders, 3 push rods bent, one 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. Total cost $3304. 79, the vehicle only has 69,801 miles on it. In addition one of the rear tail lights has a known issue (found out on google), intermittently goes out, was never notified. I took the car to jim hudson GMC to be told it would cost $475 plus tax because I did not come in early enough even though it is to be warranted up to 70,000 miles. I am greatly concerned that this engine has the same manufacturing defects of the current recall and extended recall for the GMC Yukon denali engines.

The contact owns a 2017 GMC Yukon xl. The contact stated that the check engine warning light was illuminated. The contact stated that while idling, the vehicle started shuddering violently. The contact stated that while driving to the residence at an undisclosed speed, the vehicle stalled and failed to restart. The vehicle was pushed into a church parking lot. The contact's father used a scanner to scan the vehicle, and a dtc for engine misfire was retrieved. The contact's father replaced the spark plugs, but the failure persisted. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine was blown. The vehicle was then towed to another independent mechanic, where the engine was replaced. Additionally, the contact stated that upon depressing the brake pedal, the brake pedal was stiff and required to be pumped several times for the vehicle to respond as intended. The contact stated that the failure occurred while starting the vehicle and while driving at various speeds. There was no warning light illuminated. The contact stated that the brakes had been replaced annually, but the failure persisted. The contact stated that the brake pedal shuddered upon starting the vehicle. The contact received a notification for abs from the onstar mobile app. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 148,246.

Full engine failure.

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.

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 engine developed a ticking noise which turned out to be bad lifters and bent lifter rods, and a bad valve lifter oil manifold.

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.

Lifters failed.

The contact owns a 2017 GMC Yukon xl. The contact stated while parked and attempting to start the vehicle, the contact heard an abnormal knocking sound coming from the vehicle. The contact attempted to depress the accelerator pedal however, the vehicle failed to respond as needed. The contact stated that a dealer and an independent mechanic were contacted. The vehicle was towed to an independent mechanic where it was diagnosed and determined that the camshaft was not aligned. The contact was informed that the independent mechanic would be able to align the camshaft; however, if the failure persisted there would be a cost for the repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to n232430470 - special coverage (camshaft position actuator valve solenoid - bank 2 (left side) exhaust); however, the VIN was not included in the special coverage program. The approximate failure mileage was 131,000.

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.

Engine blew at less than 80,000 miles.

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.

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.

The lifter is stuck an making a clicking noise an where on the high an truck cut off let it set for a minute then it crank by up an drove to a shop an they said it was a lifter stuck sounded like number 2 lifter this needs to be covered by GMC as a recall.

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.

Engine failure 6. 2l cylinder failure. Recall already in effect for other years. But it seems that it is needed to be expanded. I had to do a complete engine replacement and all oil related components. Metal was found easily in the oil and oil filter. I was luckily in a parking ramp when it happened so I did not crash. I was already driving for 45 minutes prior on the interstate. Could have been very dangerous at high rate of speed.

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

Lifters failed 2nd time at 130k miles. Driving on highway at 70mph cruise and engine went to limp mode. Multiple repairs. $5,000. Dealer sold it to me in 2020 with 80k miles and did not disclose prior lifter replacement. I know they did something as a head bolt is missing.

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.

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.

Drivers side tail light flickering and sometimes not working a $900+ cost! I issue with right hand side when SUV has 32k miles, seems like this is an ongoing issue, luckily it was still under warranty the 1st time. The ac condenser when out in April, also an know issue with the Yukon, they wanted to charge me $1500 to repair, I was able to find someone to do it for around $600, now the outlet and usb ports seem to not work. I also had an issue with the braking system , dealer couldn't figure it out, I finally found someone to repair it, $500 fix. For what I paid for the Yukon, you would think they would use top of the line parts!.

1. )rear brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2. )the suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3. ) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4. ) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

There was a pump in the heart of the transmission. The dealer said told me that was leaking fluid. Apparently this was a faulty hose within the transmission which leaked fluid in the transmission. Therefore, my transmission died. This was a severe I could have been a very dangerous situation if my kids had been in the car. I’ve had to pay almost $8000 for the transmission to be fixed and yeah I see that on the line there was some sort of recall but my dealership is saying there was not. I bought this car brand new and I’ve had it for seven years. I’ve never had an issue with the transmission on any of my vehicles ever.

Car has 100k miles on it. At 59k the fuel injectors went out and needed to be replaced. Then the transmission went out and needed to be replaced, then the front differential needed to be rebuilt, also had to replace the struts. Now the lifters are going out and that, plus likely the camshaft, need to be fixed. Total costs for all the above is close to $20,000. If not fixed these problems could easily result in catastrophic engine failure while driving leading to personal injury and death. I see that there is a class action lawsuit for the latter.

Lifters.

The 'active fuel management/displacement on demand' lifters failed and caused the engine to run very poorly with a significant lack of power. This occurred while driving and could have caused a crash before I was able to get off the road and out of the way of traffic. The problem was diagnosed and confirmed by an independent repair shop. The vehicle had to have the camshaft and all valve lifters replaced, as well as several valves that were damaged in the failure. The total cost to repair was just over $9000. The failure also caused the catalytic converters to become clogged, resulting in even further loss of power from the engine. There were no warning lamps or symptoms prior to the failure. It occurred suddenly as I was driving down the road. Searching online reveals this seems to be a common problem with gm 5. 3 and 6. 2l engines from 2010 onward. Gm is aware of the issues and refuses to assist in any way. Their only response is that the vehicle is "out of warranty". The failure is caused by a design defect in the afm/dod system that starves the lifters of oil, resulting in lifter failure and damage to the camshaft and valves.

The engine light has come on spuradically for the last 1. 5 years and has been consistently on since may of 2023. This starting approx. 95,000 miles. During this time after starting the Yukon it is chuggy and missing, as I drive off it jerks and darts forward. Seems to be when I stop and start to go this happens, again engine light is always on. . . Sometimes flashing. Starting 9/19/23 (106,000 miles) when slowing down to turn into a parking lot the engine revved high, no movement with the touch of the gas pedal and suddenly takes off with a jerk and a squeal of the tires. Very scary. Since then I have experienced this daily, at least once a day. So far it is when I am going slow, either taking off and accelerating or slowing down. The engine and rpms rev up and go high with no way of moving when touching the gas pedal then suddenly jerks and takes off with the tires squealing. I am also experiencing the transmission shifting very hard, mainly when slowing down. I am feeling very timid and scared to drive this vehicle. . . This is a seriously dangerous situation and can cause a serious accident or life! I believe this fits into the description of the gm class action lawsuit filed over transmission problems. When I previously talked to the dealership they kept saying that there was no recall for the problems and to bring it in. I am not going to continue to get things fixed that do not fix this problem, as I have already. I know of a friend who has the same vehicle/year only a tahoe and is experiencing the same problem and had work done at a dealership with no fix for their issue neither. Something has to happen with this problem from gm!.

The contact owns a 2017 GMC Yukon denali. The contact stated that while driving at undisclosed speeds, the vehicle started bouncing. The contact stated that the transmission also failed to shift properly. The service engine and suspension warning lights were illuminated. The vehicle was taken to the dealer, and the contact was informed that a bearing had detached, and the transmission had failed. The vehicle was repaired; however, the failure recurred. The manufacturer was contacted and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 89,400.

I have a 2017 Yukon xl with 80,000 miles on it. Last year I was driving on the highway with my kids when it began to lose power and failed to accelerate. The issue was in the engine and I had to replace the entire engine for $8000 because it was barely past the warranty. Now one year later the car began to jerk and not shift while on highway and it is the transmission that is going to be replaced for $6000. The 2017 Yukon xl is a lemon and very dangerous for drivers. I spent $45k and should not be replacing the engine and transmission withing 6 years of it's age. Reading online these are common issues putting lives at risk.

Driving towards the bank and suddenly the truck turned off … no warning nothing it turned off while operating .
