Bought brand new Yukon 2021 early Sept. Immediately drove it to Florida from PA with the kids. Issues all along the way with buttons not working and system errors. On the ride back safety system error warning popped up every 1/4 mile. Since then, its been a nightmare. Random, goofy things keep happening. While driving the mirrors will fold in and out, speakers on drivers side stopped working for 2 days, radio was stuck on 1 station for a day, rear lights will randomly flash, stopped at a red light and the steering wheel started making noise and moving all over the place, check engine light came on to be told to keep driving it til it went off then took it in to have 41 codes pop up, and on and on. There's much more... they've replaced the module now 4 times. I have young kids and I am scared to drive the thing because its always something goofy and I'm just waiting for the big stuff to start happening since I haven't even put any wear and tear on the thing yet. Out of 4 months, my yukon has been in the dealership OVER 54 days. And they just rejected my claim that its a lemon... I need to keep taking it in is their solution. Do not buy... I own a $70k dumpster fire of a vehicle that I'm stuck with.

Great vehicle when it's not in the shop. There is a known issue with the 5.3L and 6.2L engine lifters that cause bent rods and engine failure. The fanboys will tell you this is an isolated occurance...it's not. This mainly effects Yukons built before April 1st 2021. Problem is mine was built after that date and has the same issue. The forums give a very grim view of GM's ability to fix this issue as "fixed" engines have also failed. I still love my Yukon, I just don't trust it anymore after if left me stranded and it had to be towed.

I purchase new vehicles often. I’ve had every make/model car you can own. So I decided to try a Yukon GMC for first time. Issues every other day. Car wouldn’t fire, car broken into and no windows in stock to replace, 3rd row headrests have been out of commission for 6 months. I feel unsafe at this point. In addition, the interior seating is cheaply made and the exterior rear and doors are not even medal. Apple play and wifi frequently miscommunicate and makes radio stations not work. Lights are constantly going off and my video camera stays on 90% of the time thinking I’m hitting something while driving. The electrical system needs to be revamped. Purchased new in July 2020 and already 7 recalls. Dear seatbelts don’t work. This car is a COMPLETE DISASTER . Will never purchase. GMC vehicle again.

Engine Failure at 9000 Miles

The Yukon was originally delivered with a cracked windshield. Then at 3000 miles a light came up because there was apparently next to no oil. So, not a great start... Today, at 9000 miles, it left us stranded in the middle of the road. Engine would not fire. Tow truck driver saud they've been towing the new Yukon left and right lately. GM charges Mercedes pricing with none of the quality and certainly none of the benefits and perks.

I bought a DEFECTIVE 2021 Yukon Denali

I purchased my GMC 2021 Yukon Denali in the first or second week of October 2020. I put a lot of money down on the vehicle. From the time I drove it off the lot I immediately called my salesperson Josh and told him the CarPlay was not working. Every time I made a call it’ll start making a bizarre sound randomly during the call. All suggestions, service Dept, no one could fix this issue. Currently, (12-27-2020) I’m in the process of returning the truck. GM now wants to bring in their technicians to look it over before they issue a refund. In addition, the rear entertainment is whacky. And the navigation system, separate from CarPlay, was way off for some time (4-5 days) but then “fixed itself”. It would read speed signs, location, roads, etc incorrectly. It did this for about a week recently in December 2020. Still don’t know what it was about. I’ve sent proof of ALL these occurrences and still no fix/repair to this day. If anyone can get this issue resolved immediately please reach me at norhet@gmail.com. Thank you!
