Big transmission problems at 55,000 miles

2019 GMC Yukon SLT 4dr SUV 4WD (5.3L 8cyl 6A)

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.
No more GMC lemons!

2017 GMC Yukon Denali 4dr SUV (6.2L 8cyl 8A)

I too like the other reviewer here had purchased a 2017 Yukon Denali (mine was from Reliable GMC in Sacramento,Ca). With the same problems of engine noise and miss fire. After complaining to the dealer several times with their excuse that ..."Its just the nature of the car its a big engine" and after 2 rebuilds on the engine they finally replaced the engine. Although it still sounds a bit off ...(no imagination since I have had several of these same models also with other problems). Its just not worth it to give anymore money to GMC for defective SUVs that put their drivers though so much doubt and worry with an unreliable vehicle. Too bad they are a good looking car too!

GMC won't fix the problem!

We bought a 2017 Yukon Denali XL new, so even though we already have 70k miles on it, it is still a new vehicle. Too new to have a vacuum pump fail. As it turns out is cheap part that GM chose to use and now the problem is common. Now we have this transmission vibration that my dealer tells me is also now a common problem in fact continues to be a problem through 2019. The problem? GM put an incompatible transmission fluid in at factory. The Solution? flush the transmission twice with a synthetic fluid. The bad news? we are still under 5 years but 20k over the 50k warranty. The bill to fix this problem? $754. Buyer Beware

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.

Still Loving my 2017 SLT Yukon

Currently have a little over 81,000 miles on my Yukon. So far no problems with vehicle. Loving gas mileage-averaging 23 mpg on highway/city driving, love the quite and comfortable ride, and the technology is first rate. Getting in and out of the Yukon is a big step, but I like sitting up high while driving. Plus, my first two oil changes/tire rotation were complimentary. So far, no mechanical issues. my wife and I travel quite a bit between home and beach property.
