2007 Hummer with over 125,000 miles on it since bought new. It's been surprisingly trouble-free for someone who has come to expect Japanese reliability over the last 20 years.
This year I replaced the serpentine belt and the coolant hoses & coolant (afternoon garage job). Working on the brakes now - got the front axle done last Sunday. Rear axle will be next Sunday. Inspect rotors, swap pads and flush the brake fluid for fresh stuff. Have already changed the differential fluids a couple times and done a million oil changes.
About all the stealership has done was replace a steering axle thingy under warranty (defect), a couple alignment jobs (jumping curbs in the city and fallen logs in the swamp), replaced a broken hood cable and flushed the transmission fluid (couldn't be bothered for that one - all my experience is swapping oil out of 4-speed manuals).
Don't know what the hell I'm gonna do for the next vehicle since they don't make them any more. Ain't nothing quite like them on the road. 4' high snow banks cower in fear - can't wait for the first big snowfall of the season.
