Hate to say it, but I think all dealers do that. Had that happen to me several times, but usually I'm in there for a couple of things so at least something gets fixed. Worst thing the dealer ever did to me was work on the engine and forgot to replace the air cleaner assembly. I complained that it was too loud and dropped it off. They said they couldn't find a problem. I take it back and a few days later when I open the truck, there's the air cleaner assembly. I crack open the hood and slap it on, they clearly didn't even open the hood to check it out! All I got out of it was a free oil change. I went back there a few other times and mentioned that incident and word had gotten around so I guess it wasn't too common a thing for them to do.
