I have had on star since 2006, came with my monte carlo. other than the phone I have used the service two time. once with a tire. on star kept me on line from 30 mins, (of my air time), not to worry they gave me 90 free mins. tire fixed back on the road in 45 mins. 2nd time was wife locked keys in car. on star had her on the road in 5 mins. pick up my new Malibu Monday, with 6mos on star. I think on star is great. I will be using it for the next 8 yeas. sorry others are having problems. I give it 10 stars.

OnStar performed as stated and I was very pleased. New vehicle did not have OnStar cancellation was easy and friendly. Will purchase OnStar again if available in next vehicle.

I bought a new Camaro in August 2013. It came with onstar for 6 months. When I set it up they told me they were having trouble communicating with my call but they would take care of it even talked me into buying more hands free minutes. Problem is they never took care of it. When i call the advisor can not help with technical issues. Someone will call me or I can call back. This has been going on since August. How does this place stay in business? This is by far the worst customer service I have ever received from any company on any product or service.
