It's interesting and frustrating that GM won't approve a solid replacement.
I've had the initial repair done, and it's been fine since, but it's ridiculous that every time it rains, I feel compelled to go check it.
I'm deciding between waiting for it to happen again, and trying to get them to cover it, or just go do it myself at a local guy's shop
It's too bad that this is going on, I really love the truck otherwise.
Thank you for the information on pricing and your experiences!
