The car is brand new ad it seems to be a common problem between us tahoe owners that both the pilot and co pilot seats shift position randomly on turns. The seats feel like they're just placed, not bolted on how a damn seat should be. The problem is extremely annoying. You'll be turning or switching lanes and you'll hear a tack sound and feel the seat shift sides. We've been to the dealer 3 times now for the problem. We had a bit of a confrontation at our local chevy dealer because, at first, the pilot seat was shifting and moving. The, the fixed it, but immediately after the co pilot seat began to shift and move. We suspected that they took out parts of the co pilot seat to place them in the pilot seat. This problem doesn't sound like much, but when you drive the car every damn day, it starts to annoy you especially when you bought bumper to bumper and the dealer can't do anything about it. There are other tahoe owners in my local area who have the same complaint. The mechanic at the dealer said that this is a rising problem from the factory. There isn't a solution to this problem
