OnStar Subscribers Quick to Sign-up for Exclusive Vehicle Diagnostic Service

Enrollment Surpasses 100,000 in First Month Following Announcement

Detroit, Mich. – OnStar subscribers are responding enthusiastically to the opportunity to participate in the OnStar Vehicle Diagnostics program, another valued addition to OnStar’s popular array of safety, security and peace of mind services. 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.

OnStar Vehicle Diagnostics automatically performs hundreds of diagnostic checks on four key GM vehicle operating systems — the engine/transmission, anti-lock brakes, airbag and OnStar. The vehicle is automatically programmed to send the results via e-mail to the owner each month. The unique e-mail report also provides maintenance reminders based on the vehicle’s current odometer reading, remaining engine oil-life and other relevant vehicle ownership and OnStar subscription information.
