I did this against my dealer (GM) on a warranty issue the dealer refused to fix. GM contacted me personally out of Texas. 30 days my problem was fixed. (leather seat)
Had to do some leg work on my own but it was worth it. The dumb a$$ dealer forgot that I traded cars every 2 years. All my family stopped using them also. It was one of the dealers that GM saved too! Better Business Bureau does get results because most business want a good rating from them. Companies careless about a forum with a bunch of hacks complaining because you do not know if it is a lie or truth. So give it a try see what happens it does not cost anything and you will get a answer quickly.
