2021 GMC Yukon Denali 4dr SUV 4WD (6.2L 8cyl 10A)
I've had my 2021 Yukon Denali Xl since Nov. 3rd & I've driven it maybe 2weeks. It's been in the shop longer than I've had to enjoy it. Some kind of electrical problem that they can't figure out... got it back this past Saturday, after over 3weeks in the shop. Couldn't wait to get back in it & enjoy...Woke up Monday & it wouldn't start again... the same problem... talk to a few tow truck … guys & the said they've been picking up a few 2021 Denali's & Tahoe's... Very disappointing, especially after trading my Escalade
