Consumer Reviews for the GMC Yukon XL
Read recent reviews for the GMC Yukon XL
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 … give thumbs down to GMC and Chevrolet products. It’s no wonder so many people buy foreign cars —- they are better quality than American cars. 👎🏼GMC👎🏼
