OnStar Reviews

I signed up for a $6.40 rate during December 2025 for the connect plan for the app in my truck. This price was guaranteed for a year.

In June 2026, I wanted to add Wi-Fi to my truck. I asked the representative multiple times if I was able to get my $6.40 rate back after I canceled the Wi-Fi within a month, and she assured me that she could do that. After I just called and canceled my Wi-Fi, she could not offer that service back to me. A salesperson would not offer that price back to me.

And her supervisor would not offer that service back to me. I highly recommend that you do not trust OnStar in any promises that they make to you because they will not live up to it. It's a shame that they wouldn't discount me a couple of bucks for a few more months.

I hope losing a customer was worth it, and now this customer is going to do everything I can on social media and the Internet to provide bad reviews to OnStar. I hope it was worth it, OnStar.

You have been taking money out off one of my cards without my written permission for years, i called you and the guy said i need to write yous a letter and i sent it to yous weeks ago. Why havent i gotten all my money back from yous when you had no problem taking my money without my consent.

I want it back now , you did not have any write doing this to me being a senior citizen .again you want me to click your i have read and agree to your terms and dont see anything where i can read them.

But of course it will not let me send this without clicking your box. So i am taking a picture of this showing i did not read them because i dont see them.

My new vehicle, with about 3,200 miles, showed multiple issues on the driver console. The ABS and collision avoidance lights were on.

I contacted OnStar to see if my car was safe to drive. They answered after a few minutes and when I asked repeatedly if it was safe to drive, they couldnt find any information. They finally performed a remote diagnostic that showed issues with the ABS. Again, I asked if it was safe to drive because I was on the interstate.

They only kept asking if I felt it was safe to drive. Under the terms of the trial period, they should have done more to ensure my safety, but basically gave me the run around. The next week, I received notification that my trial was about to end and I needed to call if I wanted to terminate.

I called, and spoke to two different representatives that had thick accents and who ultimately agreed they understood why I didnt want to pay for something that failed miserably when there was an issue. No thanks!

So apparently, OnStar changed their prices of their plans. I have been on the essentials plan since Ive had my 2016 SRX so over three years.

My initial call to OnStar was to confirm that my credit card information was current since I recently changed the card on file during the conversation the sales person up sold me on the Wi-Fi package, taking it to an OnStar one plus plan or something like that I was on the essentials plan which cost $25 per month adding the Wi-Fi wouldve taken it to $30 a month. I was told that I would be able to switch back to my original plan if I did not like the Wi-Fi plan I called today to go back to the essential plan and was told that it no longer existed as well as the plan under the OnStar one plus plan did not include the Cadillac app which I use frequently the plan that would include. The Cadillac app was much more expensive without the Wi-Fi. I did not need the Wi-Fi and only needed to have access to the plan that I had before that no longer existed so now I have to have the one star plus plan in order to have the Cadillac app, which means that I need to pay more money had I had known this I would not have never switched from the essentials plan because I dont need the Wi-Fi.

This is a complete example of obeying switch for the consumer without any regard for transparency or your customers well-being.

I am very disappointed in Cadillac as a consumer. Consumer should be told upfront if their plans are changing before being up sold on a new item that may or may not work for them transparency at OnStar is nonexistent beware of the bathing switch that is currently in effect at OnStar.

So I pushed

the OnStar button in my car to inquire about a three month subscription note I had OnStar back in 2018 I believe so upon me signing up for the free trial they had my debit card information already saved however, Ive never put my real debit card information on file so upon me questioning a few representatives, I was told that the dealership gave them this information which was in flat out lie! When I purchased my car a few years back, it was financed through Carmax auto finance.

I never gave them my card information.

All of the information that OnStar gave me was a flat out line! I will never use this service ever again due to every representative lying to me and giving me false information!!

I give the customer rep my account number I'm looking at it and I give it to her and she said something and then she said something like I didn't understand the number or something but then at the same time she called me by my last name and I knew right then in there it was going to be a problem so I thanked her and I hung up and I went and I went to my general motors app and I talked to customer service through the chat the young lady were very helpful but Colin GM customer rep is a waste of time I will advise all people not to call just go to and chat and they will help you faster cuz now when people answer the phone you don't you know she wasn't nasty but once she realized I was I told her thank you and bye she was trying to keep me on the phone and explain situation to me but I didn't want to hear so I just thanked her politely and hung up I will never call them again simply because you have to go through the AI and she's a b**** and then you get someone on the phone that you can't understand it just a b**** don't use your phone to call use your phone to chat you'll get better service
