Stay out of California??? I would think that would be one of the best places to check out/test trailer brakes!!! :-)
But GM has CYA'd by the last sentence of the letter..."Please keep this letter with your vehicles owner manual for future reference"...Ha!!!
GM is being ridiculous, making us pay for their design flaws. As I posted earlier "GM should do this "No Charge"!!!!"
