Vehicle was 300 miles out of warranty when I get a service trailer brake warning on my info center replaced a blown fuse and the fuse blows again, no trailer has ever been hooked up to this truck. Went online and inquired about this problem and there's thousands of post and complaints about this problem, even on a GM site there's a PI investigation about this problem, why doesn't GM just do a recall to fix a problem they know about. I'm getting ready to buy a travel trailer and now I don't know if its safe to pull it!
