Dear Car Talk: I have an ‘07 Chevy Tahoe. I had an ‘02 prior to this one, and it was indestructible. The ‘07 has an issue that no one can figure out. This sounds ridiculous, but I’ve got witnesses who have driven it and have had the same experience. When I drive my Tahoe in the snow, it bucks and bangs and sounds like a piston is going to come up through the hood — but only in frozen precipitation!
