The Chevrolet Tahoe is the less luxurious brother to the GMC Yukon and proves to be slightly more durable. I suspect the more utilitarian Tahoe is simply used more often and does not represent a more reliable package, especially considering the Yukon and Tahoe share similar drivetrains. The Tahoe ties the GMC Yukon XL with 4.1% of listing showing over 200,000 miles.
