In the first month since OnStar launched the innovative, new, monthly e-mail vehicle diagnostic service, enrollment has surpassed 100,000 customers. "As we had expected, our subscribers have enthusiastically embraced OnStar Vehicle Diagnostics. Now, over 100,000 vehicles are sending their owners monthly e-mails to tell them how they are doing," said Chet Huber, OnStar president. "That's just part of what OnStar brings to GM's Total Value Promise, giving customers unique, important services and, in this case, at no additional price," he added.
