Disappointed - the roof leaks after 2 years

Linda E., 10/23/2023

2021 GMC Yukon XL AT4 4dr SUV 4WD (5.3L 8cyl 10A)

Bought our 2021 GMC Yukon XL SLT brand spankin’ new off the lot. No complaints until 2 years and 20 days after ownership when the roof leaked on a rainy morning. The water poured into the car through the interior light covers and control panel above the driver and passenger seat. Water also poured in through a lower duct by the driver’s left leg. GMC would not allow a warranty on it. We …

I love my GMC Yukon XL but not love at first sight

2021 GMC Yukon XL SLT 4dr SUV (5.3L 8cyl 10A)

The seats are comfortable and the steering wheel has conformed to my grip. My 6 and 8 year old grandbabies can operate the rear entertainment system with no issues. I still wish it would work with an iPhone instead of just an Android phone. I …

Lauren, 06/29/2021

2021 GMC Yukon XL SLT 4dr SUV 4WD (5.3L 8cyl 10A)

We just bought a 2021 Yukon XL SLT and came from a 2009 Yukon XL Denali and we LOVE it! We loved out older Yukon but it was time to upgrade and we have zero regrets. We are a family of 6 and this comfortably fits us all and has a ton of room for storage for long trips. Very smooth and quiet ride, Bose speakers, a lot of safety features. It's completely different that the previous …
