OnStar By GMReviews of onstar.com

On January 21,2025 | activated my vehicle remote start through the online app. 10 minutes later I went out to my 2021 Silverado to find that my passenger front door glass had been broken out and there was glass on the ground and through out the interior of my vehicle. Personal items and tools had been stolen from my vehicle. I called the sheriff department, my auto insurance, and OnStar! OnStar told me that they had received notification that my factory alarm system had been activated, but they OnStar had not notified me of the break-in. They said they would investigate to determine why such a failure had occurred! This was over a month ago and I have called OnStar every week without fail and they never have responded back to me! If you are considering buying OnStar for this added security, based on my experience, THINK TWICE!

Having a nightmare sign up. Press the blue button in the car. Someone from the Philippines answers the phone. Their English is so broken, they give me a fake name Jack. No Filipino has the name as Jack and there English is so bad. I just gave up after several tries. Definitely this is a bad company, they don’t have answering service in Canada.

The absolute worst! Have been trying to cancel since March 2023 and keep getting passed from on person to the next and all empty promises. They are terrible. DO NOT SIGN UP

Terrible customer service I wouldn't have it if you pay my number I've been there since 2017 I have to call in all the time you called for directions and it takes you all around the world it's terrible I keep it cuz I I keep it cuz I'm single but I wouldn't I wouldn't about if I had a choice I

They don't have a cancellation option on the website. They have but I cancelled my service on 12/03 and they charged me again this month. I couldn't get rid of them. Worst service ever. I'm going to my bank and dispute that charge

they will take your money and screw you over even if there fault and they have know idea what there doing. dont use them.....

Worst customer service ever. Chevy app says 3 months free trial. I called and was told 1 month free and with a card on file i would get additional 60 days. Finally after 3 more days i get app link to chevy onstar app only to find out it says trial period is almost up. Call to cancel and its like pulling teeth, one person says no supervisors are in then next minute they are busy. All but impossible to cancel the account...

The absolute worst. I've spent so many hours trying to get the wifi that I'm paying for work in my brand-new vehicle. Hours and hours on the phone to get it set up. Then when my free trial ended, the nightmare really began. I spent 5 hours, multiple phone calls, and chats. No one could help me. I was told to go to the dealership. Then I was told a technical support person would call me in 3-5 days. Their script of "how is your day ma'am and I'm so sorry for the inconvenience" is garbage. If there was any other way to get wifi in my car, I would never sign up and pay this company for the ridiculous technical support I have received. I STILL don't have wifi working even though I'm paying for the unlimited data plan. Avoid if you can. They are a nightmare.
