few days ago I saw something like Car and Driver or some show like that discussing On Star. It seemed like a paid ad by GM(only the best things to say) but it was in the middle of a real show so who knows. Anyway one guy actually said "Onstar can read your codes when a check engine soon light comes on and report back to you if its a big or little problem. On star is like Big Brother." And that was it, no, and thats scary, he seemed happy about the idea of having some big brother watching over him. Sorry I don't care if it will tell me when I need to check my oil, I do that enough by myself man. /forums/images/graemlins/shame.gif oh I started thinking about this cause my buddy went "mudding" in his 04 1500 and it has On Star. He has some weird driveline vibe thing going that was there before he went off road but he was saying how he wondered if somehting like Onstar could tell he went off road and void his warranty or blame it all on that. I'm sure they wouldn't do that right now but it wouldn't surprise me to hear of that someday.
