Noticed an issue with the roof one afternoon, three indents on each side just after the windshield inline with the support pillar. Nothing was placed on my roof, and I only towed a 17.5 ft ranger boat. Toyota rep had no idea what caused it but also wouldn't fully cover the fix even though I still had plenty of warranty time left. Also could not guarantee that it wouldn't come back again after they fixed it. Can't believe Toyota won't back their own product.
