OnStar is not only useless, their customer service sucks and they're idiots. I traded in a GM Vehicle that had an active OnStar account and phone number with it, called OnStar BEFORE the trade in to be sure I could port the phone number on my old car to my new car and was told I could - that all I had to do was call their billing department when I got my new Avalanche and they'd transfer my information over. So I did that but guess what? Post purchase the new rep claimed they couldn't do that - that the phone number stays with the car. Really? I can see the PHONE staying with the car [obviously] but the phone NUMBER? As I said, IDIOTS. After speaking with her manager and getting absolutely nowhere I took my complaint to the dealer who sold me the new car - also useless. They claim to have talked to the regional OnStar manager who basically said "Tough sh!+". They told him of my threat to cancel my OnStar subscription [despite it being 'free' - of what, can't say since it certainly isn't free of aggravation] and they claim he offered me free minutes but if wasn't good enough I could cancel." Nice, huh? Needless to say I am in the midst of constructing a nasty-gram to Linda Marshall and Dan Akerson. Bottom line, if you're considering buying a new GM vehicle and expect to transfer your old vehicle's phone number to your new car, good luck. I've always loved GM cars, despite their countless mechanical issues, but this one is definitely the last. This has been a horrible experience, SO not worth the aggravation, especially for the price. In restrospect, I should have bought the Sport Trac, instead.
