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!

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.

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.
