OnStar By GMReviews of onstar.com

Service was not 5 star for us. We had a vehicle problem at mountain, Santa Fe and contacted to On Star. They assigned the towing company but haven’t assigned the transportation. They said they don’t assign the towing company and transportation vehicle same time. So we need to stay at mountain after our vehicle towed our vehicle. It was December 25th, Christmas. Temperature was 32 f and our kids stay out side the vehicle also. They were trying to assign the our transportation and we have been waiting over 20 minutes and their answer they can find the transportation vehicle. So we called Uber and pay the extra money for our transportation. We pay monthly fee to On Star, but they do not work as fee we pay.

Called to put another vehicle on my plan, the idiot created a new account of which I'm paying for but isn't working. I've called now 4 times to fix this & I keep getting the run around. On star sucks!!!

I had the unfortunate experience of trying to talk to Onstar on Sunday regarding my inability to connect to the wifi in my Traverse. After telling the rep 4 times I received a message saying I can not connect because of security settings, he continued to ask me to connect to the Internet. So Onstar tell me why do you have reps who number 1 cannot command the English language, and #2 do not listen to the customer?

They towed my car to the wrong dealership without asking me and had to pay out of pocket to tow it back to my dealership!!

OnStar used to be good, now......the way that they updated their subscriptions is criminal!!! They now have 2 tier subscriptions, 1 for new vehicles, and 1 for older vehicles. The newer vehicles are cheaper than the older ones. And then they raised the prices to boot! I will never renew with OnStar again! It's a damn shame that they have turned into criminals! BEWARE OF ONSTAR!!

Unacceptable experience with OnStar. I still can’t believe this. I thought Cadillac was a luxury brand with excellent customer support, but I am in shock. It’s been more than 50 days and I have not received any response. My 5G connection has stopped, GPS is lost, and multiple times I almost had accidents due to losing my way. Apple CarPlay doesn’t work as Cadillac promised. This is supposed to be “awesome” customer support?

Onstar is a black hole. When I bought my new GM truck the salesperson told me to "hit the blue button" to start my complimentary service. Big mistake!. All they wanted was my credit card info. I specifically asked them if I would be notified prior to my "complimentary" service ending and my card being charged. They assured me I would be notified. Fast forward and I happen to be looking at a credit card bill and see Onstar charges on there. I immediately call them to resolve the issue. After 34 minutes on the phone, mostly on hold, they again assured me I would be refunded the for themonths I was not aware I was being charged and never used their service. This never happened and I received a "Dear John" email several weeks later. After pushing this up the chain, writing multiple letters and making many phone calls I again received the "Dear John" email. Onstar is not honest. Do NOT give them your credit card info unless you truly want to spend $34 a month for nothing. They will NOT notify you when you "complimentary" service is up and they start charging your card.

First, and foremost my husband and I I have purchased two Chevy Camaro’s . One in the year 2014 and upgraded to a 2019 . Both vehicles were brand new . Since we were introduced to Onstar , I thought it was a great idea and opportunity to have . Well over the course of the service contract issues began to emerge. Within the 2019 monthly diagnostic reports are suppose to come to my email address each month on the 24th. I have been accuse of hacking into my email account in which I followed up with my Servicer who supply’s me my email account. Ultimately, the finding were not true . Secondly, technical support “ stated they changed to another company “ When that happened I didn’t receive my vehicle reports in about two months. Complaints were filed either corporate and GM . Shortly, I was on the phone with connectivity and she said the report was generated to my email and had the audacity to then asked me if I received it . Common sense would have told her if I did receive it then why am I speaking with you ??? She placed me on whole two times after 10/ 15 intervals . They never show professionalism to their customers just leave you on whole . I waited the second time and she never came back and the call ended. You ask for a supervisor and they always said “ one will call you back “ Supervisor’s in my experience don’t call you back . Onstar, is the worst company of representatives that I believe are train just yo tell you anything but the truth. I used to have payed subscriptions and cancelled them all because they wouldn’t used the correct CC to get the payment. The used CC that should have been deleted from the system as I called them and reported and gave valid payment information. If I could , there would not be any star ratings because they certainly don’t deserve one. They are an F rating company in my opinion. 😡😩😤 !!!!!
