Brake master cylinder booster replaced twice.
Front wheel drive electronic switch does not work, so 4WD is inoperative.
Transmission oil cooling lines leaked and had to be replaced.

Serpentine belt tensioner was defective.
Leather seats are showing some cracking.
Maintenance/replacement: New alternator at 90,000; new brakes at 84,000; new battery every 4 years, new tires at 84,000 (used a five tire rotation - and bought a new wheel for spare tire rotation) ; automatic interior light dimmer switch is defective, have it turned off.
Although the repairs are beginning to get more frequent, I really like this truck. I bought it used at 9,000 and did not have to take the big hit driving away from the dealer. First thing I did was take it to a rust proofing shop and have it undercoated, glazed, rust proofed and detail cleaned. With their Gold package, it gets redone annually -and it has no rust at all - and it still looks like new.
It is a great road car with plenty of room for four adults, five is OK. The 5.7 engine will really jump up and move you along, passing or cruising. Rides along very smoothly.
You wasted your money on the rust proofing. I have the same truck, I am the original owner and it has no rust. Zip, nada.
The only rust protection it has is what it came with from the manufacturer.
I live in Detroit, the winter "road salt" capital of the world.
