Kacharo

I was wondering if anyone else was having problems with their wheels. I have the chrome five spoke wheels. They are corroding and peeling around the valve stems and few other places. I am now having leaks at the bead from corrosion inside also. It started about a year ago and two dealers said they are seeing it but GM will do nothing. I've had three Denalis prior to my Suburban that did it also. The denalis where covered under warranty. I am the original owner on all of them and never seen a automatic car wash. Washed and waxed by myself and was told that its an issue on care. I always loved my GM products but this experience is very frustrating. It is sad that this keeps happening on their vehicles, especially their higher end ones.
