The majority of OnStar users are happy with the service, and the many real-life customer stories on OnStar's Web site seem to confirm this. But not all reviews of OnStar are positive. Some users call the service "Big Brother" and say that the service can lead to an invasion of privacy.
In addition to airbag deployment and impact severity, the Vehicle Comm and Interface Module can also record whether you're wearing your seatbelt or how fast you're driving. It keeps data related to events immediately before, during and after a crash for about 45 days. The Call Center retains received information for over a year so that it can maintain quality and follow-up on customer complaints.
OnStar says that it passes this information on to auto manufacturers to improve vehicle safety. However, critics speculate that it could also be used to:
- clear auto manufacturers of wrongdoing
- deny warranty repairs
- find you at fault in an accident
- increase your car insurance premiums or change your coverage

Some users dislike that they have to call the OnStar center to use the GPS receiver in their car, so they've found ways to "hack" into the system and obtain GPS data in real-time. One Web site gives step-by-step instructions for doing so. GM does not advocate any tampering with the system. If hacking attempts or modifications render the service inoperable, OnStar is not obligated to repair it.
Although OnStar may be the most popular vehicle telematic service, it's not the only one out there. Other car manufacturers offer similar systems:
Japanese automakers Toyota and Honda licensed OnStar technology in previous years, but both companies dropped it in favor of developing their own systems, called G-book and Internavi, respectively. Nissan also has its own telematics service, called CarWings. All three are only available in Japan.
