Solid Effort with great new Transmission

2018 GMC Yukon Denali 4dr SUV 4WD (6.2L 8cyl 10A)

Great engine and new 10 speed transmission. Shifts really smooth and its never guessing on when to down shift or search for gears. Great on the highway. Rear visibility due to the middle row seat and C pillars is poor at best. Must use your mirrors and trust the tech. The tech is awesome and unrivalled by others. Touch screen is easy to use, love the layout, response time is great. High step in, but its a big car and I knew that. Gas mileage is ok for a big car, cylinder deactivation is seemless. Turning radius is good for a big SUV. Overall please so far, two weeks under my belt.

Very excited to take delivery of our new 2018 Yukon Denali. Was very surprised at the power and handling as my wife is very pleased! I will say there are a couple of things that took me. We did not purchase the XL but the regular length SUV (thank god we don't have to fit in the third row) as the rear cargo area is small as expected. Automatic folding seats are nice when doing a Costco trip or traveling. What we did notice, which really had me wondering is the very rear cargo area does not have a light! Strange enough, with LED technology being so inexpensive you would think that they would have addressed it. Other than the issue with lighting, we are very pleased.

Big transmission problems at 55,000 miles
Former GM customer, 02/03/2021
2019 GMC Yukon SLT 4dr SUV 4WD (5.3L 8cyl 6A)
11 of 11 people found this review helpful
I had no idea there were any known transmission problems with 2015-2019 GM vehicles, but I'm very aware of that now through personal experience with this vehicle and after having done some research. I drove my previous Yukon (2013 SLT) to 165,000 miles without ANY PROBLEMS at all. I literally just changed the oil and rotated the tires/replaced tires when needed. Nothing else ever went wrong with the 2013. I decided to trade for the 2019 because it's a beauty, and I fell in love with it. It has been a good and dependable vehicle for the most part, but it started making a harsh whining noise with cold start-ups at about 50,000 miles. The noise seemed to originate underneath the vehicle at about the level of the front seats, and that just got progressively worse in a relatively short amount of time. It was so loud that I was embarrassed to start my car at work if anyone was around. Of course the dealership "couldn't hear the noise" (which is BS because is was obnoxiously loud). I finally told them that I had read about the known transmission issues in this vehicle and I was CERTAIN that there was a transmission problem, and if they didn't figure it out I was going to take all of my future business elsewhere. Lo and behold, they found some pretty significant transmission issues (shocker). Gears were ground down and my transmission fluid was foul-smelling and orange-brown. I hoped for (and requested) a new transmission but they are currently replacing the only the severely damaged parts of my transmission because "that is all they were able to negotiate with my power train warranty company". I plan to trade as soon as I get her back because I feel that I've been deceived from the very beginning, and I should have received a new transmission. I drive a lot of interstate miles, some at night, and I don't trust that this is the end of her issues. I will NEVER buy another GM vehicle, nor will I do business with this dealership again in the future. There is no way that they weren't aware of the likelihood of transmission issues in this vehicle. I feel like they were trying to placate me until my powertrain warranty ran out in 5000 miles, and now they're just putting a bandaid on what I believe is a much bigger problem. It is a BEAUTIFUL vehicle, and I will be really sad to say goodbye to her.

I have now owned two of these. After my 2015 started falling apart at 85k miles I decided to buy a brand new 2020. Although warranty has covered most repairs I am def selling before the warranty expires. Here is a list of known issues and what the deal would have charged for each repair. - front struts (magnetic) leak -1,800. - oil cooling line leak - 400 - radiator replacement - 1,100 - AC line pinched -400 - steering wheel “o” seal leak -900 - transfer case leak - 1,900 - break caliper leak - 700 - DVD player blacked out - 790 - constantly out of alignment -100 every oil change This is all in a truck that is <2 years old that cost me almost $80k. My wife’s Mercedes Benz has had minimal problems with twice the mileage and repair bills are similar to the Denali -

Update: Had to trade out of this junk with a huge loss... Read below why. I was so looking forward to purchasing my first real large SUV. Reviews on GM Tahoes and Yukons are positive but my experience was terrifying. My wife and kids hate to ride in it as it shake at idle in Drive position. GM and dealers are saying no codes, we stopped troubleshooting here. $65K truck that shakes like 1988 Yugo... what a treat, but what is worst is the lack of support. If you think manufacturers warranty is there to support you bumper to bumper, think again, if truck is dead or there error codes they will fix it, if no codes you are so out of luck. I took it to the independent, they found the issue with injectors but since there are no codes, GM would not authorize a repair. GM support will send you on such long wild geese chase, you would never come back. I am pro-business but in this case I wish there was more consumer protection in place.

My wife had a 2006 Yukon and loved it. Only reason she got rid of it was expense to maintain it. She got another SUV and hated the mirrors. She felt very uncomfortable attempting to back up. Visibility was the problem. She traded it in on the 2018 Yukon and loves this. Only problem is the rocking on uneven ground. We park on the front yard and its bumpy. The vehicle feels like we are at sea. It rocks from side to side. Other than this, the comfort is the best we have experienced.

Only time will tell for sure but after owning my Yukon SLT for 3 months and 2600 miles I absolutely love everything about it. The 0ne exception is the 3rd row seat is short on leg room for average size adults. Not a problem for us because we seldom if ever us it. I would buy this vehicle again in a second.

I have been driving a 2016 Yukon for 2 years, and now the 2019, so I have a pretty good knowledge of Yukon XL Denali. It drives more like a car, doesn't not feel as big as it is. I exchanged the 22" wheels for the 20". I think 20" gives it a better ride. Compared with other vehicles in its class the only think, I think it lacks is the seats could be a softer leather. Not as nice as Escalade ESV or Lincoln L but it is $15,000 - $20,000 less so I think the value is a great deal. I've taken trips cross county with it, and it is a smooth ride, cabin noise is quiet, acceleration plenty to get up and go when I need to.

replaced a loaded 17 SLT - 5.3 with a loaded 20-SLT-5.3. Everything has worked fine, did have to have the antenna replaced (warranty). Other than that zero issues. Primary complaint is the 6-speed transmission has slightly different shift points and overall the truck gets a full 1-MPG less than the 17 did.

I have now owned this vehicle for 15 months. All in all it has been a nice vehicle. The main complaint is the backend is so HIGH up I have to climb up in to load things. I'm 5'6. It has a smooth ride. I feel safe in this vehicle. Extremely nice looking vehicle. It hauls my 5x10 trailer with ease. I buy cloth in any vehicle (it's what I like. NOT leather.) The cloth in this vehicle does not clean easily nor does it look premium as have my other vehicles. For the price very disappointed. Leasing this vehicle not sure if I will purchase or not. Still deciding. UPDATE: 5-3-2023 I have now finished my 39 month lease. I still love this vehicle. It has the room I need, the main thing is comfort, safety and reliability. I live in Michigan so it is perfect during the winter months getting through snow. We took it on a trip two years ago to Florida and I would recommend this vehicle to anyone for short travel or long. It does have a v8 engine so it does take more fuel. But still well worth it. Seeing as my lease just ended. I looked around at other dealerships and vehicles to see if I was missing out on another opportunity for a better vehicle. But I have looked far and wide and cannot find anything that compares to this vehicle and all the perks it has. Therefore I went in today to purchase the remaining balance.

Vibrations issues that start at 45 mph. After ruling out tire issues, 3 sets of tires later, GMC is trying to find the issue which has been a problem with the GM truck/Suv line since 2015. Currently my GMC dealer has had my Yukon for 3 weeks working on the issue. Yukon overall is a very comfortable, fuel efficient SUV with some issues. Update 01/19/22 still having the same issue and actually filled a lemon law complaint. GMC now has assigned an engineer inspect my 2019 Yukon. So far, GMC has replaced the torque converter and balanced the drive shaft....still vibrates and has a whine coming from the differential which has been repaired three time and now actually needs to be replaced but part (differential) is not available...Inspection is on 01/20/22. I have little expectation from GMC customer service/inspection...poor customer service at best!

Amazing engine 10 speed V8 shifts very smoothly at all speeds. Drives like a big car. Great towing capacity and power. Lots of interior technology features and luxury comfort for all passengers. This is my second GMC Yukon Denali after BMW, Audi and Range Rover vehicles previously. Highly recommend.

Rides like the truck platform it sits on, but thats why I bought it coming from a HD2500, It's definitely a quiet ride, cornering with maga ride is funtastic. Power and exhaust sound is nice. Overall I love it, will update as I put more miles and start towing

I just picked up my Black on Black 2020 Denali in Feb and I get so many compliments on it. I love everything about it and it has everything I was looking for in an SUV. I test drove the Denali XL and I felt it was a little to much for me since I was by myself. I recommend Earnhardt GMC Mazda, Buick in Las Vegas if you're looking for excellent customer service and they treat you like family. This is my first GMC SUV and i'm in this for life... Victor B.

2018 Yukon Denali XL. Buyer beware! For many many many years the Yukon Denali has been my dream car. Work hard and paid for a brand new Denali. Did not know the trouble I was heading into. Yes there is a tune you may install to fix the rough idling issue, if you are willing to give up your manufactures warranty. I have accumulated a total of 13,600 miles and this vehicle has left me dead on the road 3 times. Beginning to wonder if it’s why they provide on-star. My 2006 Nissan Titan with over 186,000 miles on it is more reliable. I paid for bells and whistles and got smoke up my bum. As mentioned in some reviews I found ride is smooth so long as you never stop.

Very frustrating and disappointed that the A/C had a faulty muffler line assembly off the compressor . Had at the dealer at 740 miles found no refrigerant in system filled system added dye leak detection. Two weeks later May 7 2019 took truck back the dealer system not cooling. Replaced mentioned part and filled system seems to be working now . How can this have happened??

Recently purchased the princess. I’m not a car geek, just a mom who wanted a bigger vehicle that would fit 2 people and 2 Labradors and comfortably get us up north. It’s like my living room has been transformed into a vehicle. It’s so comfortable, so quiet, so smooth, so beautiful. It’s everything you could ever want if you need to go far with lots of room. I will never own a black interior again in my life. She has a tan interior which is cool in the summer. People can find fault with any vehicle but as far as I’m concerned it’s the nicest vehicle I’ve ever owned. I just feel so safe driving her up Highway 11 into two lane north country. (Ontario). But most importantly, my dogs love it. I will drive Yukons until they take my away my license and stick me in a home!!

I love my Yukon Denali- it’s the third one I’ve owned and it’s awesome. It handles well, has a great turn radius and I can cart 3 grandkids and strollers and 3 more adults. It’s been a great, reliable ride. I loved the 4 wheel drive when I was caught in a blizzard a couple months ago. It saved the day.

This is the second Yukon that I've owned. Within the first couple of months, I started hearing a noise once the speed reached about 45MPH. I took it to the dealership and dropped it off a couple of times. Service manager stated the mechanic couldn't find a problem. After the second time, I asked for a mechanic to ride in the truck with me to point out the issue. He agreed that he heard the noise and tried to tell me that it was normal...which it wasn't. Got back to the dealership and the service manager proceeded to tell me to turn the button on the control and it would make the noise go away. He was referring to the radio volume button! Prior to this happening, the front panel wasn't flushed and seemed off. Dealership had to replace the entire back panel and then had it painted. Overall, I truly regret this unnecessary purchase!

1st I really enjoyed this vehicle, loaded up family, carry extra kids, drop seats and carry plenty of storage. Internment problems with various electronic functions not working. Then at 37000 miles became more frequent. Finally after 38000 dead in water, no response to key fob, not start, three times in three months, dug around fuses, would come right back, Finally disconnected the loose negative cable and still concerned. Enjoyed but worried when would be next time it would die.

I bought a brand new 2019 Yukon Denali. First couple years I was in love, then around 54,000 miles I had not one not two not three, but all four magnetic stretch go bad. It was like riding in a tank even the shadows on the road felt like bumps, after much arguing and many phone calls I got GMC to do it for half price, each strut is about $1000. 15,000 miles later I had both front struts go bad, I asked for them to put something other than the magnetic struts back onto it, that’s all that’s available the dealership this time stepped up and replaced both of my front struts at no charge. Now I have a funny sound shifting from 1st to 2nd and from 2nd to 3rd, doesn’t really seem to affect it’s performance but I know there’s something wrong with it and with 70,000 miles on it GMC ain’t gonna fix it. I will not be buying a new Yukon Dinali even if I can’t let go the steering wheel clap my hands and clap my legs.

No question, best vehicle I've ever owned over 50 years of car and truck ownership. It has a quiet and comfortable ride with decent gas mileage (combined hwy/city 19.7mpg with best hwy north of 24mpg). Limited off road use but performed without missing a beat on steep/rocky/terrain. Same in the snow. I have over 95K miles on it with no mechanical issues worth noting. I follow the severe driving maintenance schedule for fluid changes and change the engine oil every 5K miles. Plan is to keep it past 200K miles.
