  • Product questions
  • Warranty claims

Best Practices for Calling OnStar Customer Service

Before calling OnStar, make sure that you are using the right number. OnStar offers both a standard toll-free customer service number as well as a TTY number for deaf and hearing-impaired customers.

Have relevant documentation on hand before calling. This might include your subscription agreement, billing statements, as well as your car make and model. It's also wise to have pen and paper handy for note-taking during your call.

How Do People Feel About Their Calls to OnStar Customer Support?

OnStar has been around for a while so it is not surprising that you can find a range of opinions about its service online and in the news media. Since OnStar provides a service as its product, it is sometimes difficult to distinguish between OnStar's customer support abilities and the OnStar service itself.

Some of the more significant complaints involve misunderstandings when it comes to billing and subscription issues. Some people feel that customer service representatives are too aggressive in trying to get callers to upgrade their plans. Others state that OnStar does not process cancellations in a timely manner.

What Kind of Issues Can OnStar Customer Support Resolve?

OnStar customer support can resolve many issues by phone, including answering questions about the service, assisting with subscription purchases and changes, and providing technical support.

What Can't Be Resolved by Phone With OnStar?

OnStar is a service, so its representatives can handle most issues over the phone. If there is a problem with your car or your call button, an OnStar agent may be able to troubleshoot the issue but you will need to work with your dealer or mechanic to make repairs.

What Can I Do If I Am Unhappy With My Call to OnStar?

If you get off the phone with OnStar and feel as though your issue was not resolved, don't give up. There are still options.

First, look over the notes that you took during your conversation. If you didn't take notes, spend a few minutes jotting down or typing out what happened during the call. Understanding where things went wrong during your initial conversation can help you get things back on track.

Next, call OnStar again. The next representative to whom you speak may have more experience or training. He or she may be able to resolve your issue for you.

If you are still unable to resolve issues with OnStar by phone, you may have some additional options. You could open a support case through OnStar's website if you are already a subscriber. Another option is to reach out via one of OnStar's social media platforms. A third option is to send a letter via postal mail. While this is a slow option, it may be effective as the person who reviews your letter may be in a position to give your letter a considered review.

Another option is to talk to your car dealership if it sold you the vehicle with OnStar installed. The manager may be willing to advocate for you with OnStar or to address technical problems in-house so that you don't have to go back and forth with OnStar customer support.
