OnStar By GM Reviews 

Terrible. Don't do the trial because they will just quietly start charging your account even when you still have time on your 3 years free offer. My husband tried to cancel last night but the cancellation department was closed. I called today because my husband work schedule is not flexible and they said only my husband can cancel. It was super easy signing up but a pain in the butt canceling. Shady company. I'm not so sure I am so gung hoe to buy another Cadillac in the future.....

Their app isn't working as it should be. It has been used now for so many years and still they are not able to make it run at an acceptable level. They keep you paying every month and then when you need it, it doesn't work, and they don't care. Because if they would they would refund you, but they don't. Now after many years I tried it again on my new truck, weren't able to connect my truck to the app for a month, now that it is connected it is connected to Mexico, and I am in the US. When I contacted technical support on the OnStar Community website They asked me to submit certain information from my phone. I did so and the the reply was rejected right away, Then I complained and they labeled my reply as spam and got cut off!!!! This service from GM isn't worth the time nor your money!!!! Terrible customer and technical service!!! I would have added the screenshot, but it isn't possible to do so in this review.

Horrible service 😑 I was stranded 5 hrs on side of the road ,they said 1st tow truck was on the way but never showed,I called several times same smart mouth agent and then the second tow truck 2hr later with over 1,000$ bill and they will not refund any service after you complain for over 2 months and then they want respond to your email.

If I could give less than 1 star I would. I was coming up on the end of free 3 year paid membership for Onstar after purchasing a GM car and was offered a promotional code to renew for a year. I took advantage of that code and have email confirmation of the price I approved to be charged to my car yet I was charged full price. When I called to inquire, I was made to look like the villain and it took multiple calls, long wait times and ultimately cancelation of the service to get this corrected. I find it ridiculous that a company is willing to lose a customer, rather than help them. This sent a clear message to me that GM and Onstar do not value or respect their customers and I will never be a customer again.

I wish I could give this negative stars!! I got stranded 2 hours from home because of the incompetence of a OnStar agent. I have had OnStar on my 2016 Buick Enclave since I bought it. I happened to notice that I didn’t have the remote access I had when I bought the car. I contacted OnStar and they informed me that it was because I had switched to emergency services plan. I was paying almost $20/month for virtually nothing. They told me that if I switched to the connect plan that I would have remote access. Get this, it was cheaper!! I switched my plan on February 18th. On March 4th I travelled to St. Albans, VT. I accidentally locked my keys in my car. I thought, no problem, I can open it with my phone. WRONG!!! This is when I discovered that I had no plan. Apparently, when the agent processed the annual payment, she had a slip of the finger and set the term from 02/18/2026 to 02/17/2026, effectively canceling my account. When I contacted OnStar to unlock my vehicle, I was told that they couldn’t do it because I didn’t have a plan. I explained to them that the agent had screwed up and told them to process the payment again. They told me to he only way I could reactivate the account was to push the blue button in the vehicle. I asked them how I was supposed to do that when I was locked out? They then told me that I would need to contact Roadside Assistance. That was another joke. After about two hours of waiting for them, they informed me that they couldn’t find anyone to come out that evening. This is after they already charged my credit card $94.00. I am still trying to recoup that money. I’m was finally able to obtain the services of a tow truck company to get my vehicle opened. That was another $165.00!! So a 1 hour and 45 minute drive from to home took me over 8 hours. I arrived home after 2:00 a.m. when I contacted OnStar to request reimbursement for the charge, they refused. I told them I wanted to speak with senior management. They then gave me a non-existent telephone number. I went online and found a form to file a complaint. To date, no one has even acknowledged receiving it. STAY AS FAR AWAY FROM THIS COMPANY AS YOU CAN GET!!!!! CUSTOMER SERVICEIS NON-EXISTENT!!!!! SAVE YOUR MONEY!!!!!

It says it's road side assistance, but apparently won't go on anyone's private property. So what is the point?

Run!!!
Onstar is the worst on a categories, especially container service. Every phone call is the same story (someone will call within 3-5 days) they never do. My issue is 2.5 months and counting.

But they love to charge every month and on time for that

By far the worst ever,
You get better quality and service talking to a post

Wow... Couldn't be a worse experience. I had an accident in a dead zone near my home. I couldn't reach my husband nor even 911. I remembered Onstar. Pressed the red button... it came back saying I needed to use the Blue since I wasn't a member...ok, ok... Calm down I'm telling myself.... I pressed the blue button and had an advisor but it didn't seem all that quick! After multiple questions/answers in the car (frigid temps out), I was told they would give me some instructions. I was listening but of course I was shaken up too. (I was not hurt physically but the reality of it all was now sinking in and making my thinking a bit fuzzy.) One of the instructions was to "Turn on the hazard lights".. I did that ... and THAT DISCONNECTED ONSTAR!!!. Did I get any call back?- nope. Did the police ever show up? Nope, I ended up walking out to the street and luckily found a spot that took my call after a Good Samaritan stopped. Onstar knew my location due to GPS but still never dispatched anyone. I would NEVER buy that service.

so if you get onstar with your car great BUT when it is time for it to end they have a grteat bait and switch emain of we have plans starting at 9.99 a month whan you look at plans not one starts at 9.99 a month pick one out do it right than because we had two wait twos days to pay day then it went form 200.00 a year to 500. ayear as nice as it would have been to keep it we do not do bussness with companys that play these kine of disonise games

After December 31, 2025 my chevy app no longer received data from my vehicle. I could start it and locate it but no data. I finally got someone at Onstar to sync my vehicle to the app. But now I get 6 phone calls a day pertaining to the onstar button pushed in the vehicle. Each time it is not my vehicle but my cell phone, email address and name is attached to it. Right now I have a 2025 Colorado listed on my app, that says I own, where I can start, blow the horn, flash lights. I have been trying since the 6th to get this straightened out asking each time they call about a vehicle I do not own, to please speak to a supervisor. NO LUCK

If I could give a 0 I would.

This is the first time I have ever had to use OnStar. It came with a 3-month free subscription. I also had it free on my previous EV but never had a need to use it.

I was in a parking lot of a fast food restaurant. Took 4 calls to OnStar during the 1-1/2 hours until tow truck showed up.

I was asked twice where I was? I couldn’t believe it. I thought OnStar could tell where I was located? Put on hold for at least 6-10 minutes while they figured out where I was and what was going on with the tow truck?

I have a 2026 EV Chevy Equinox so I had all the bells and whistles. So I was in a warm vehicle the whole time.

I would never consider extending past the 3-month free subscription.

I purchased a Cadillac Escalade ESV Sport Platinum primarily for Super Cruise. I fully understood it required an OnStar subscription, but I was explicitly promised on a recorded call that all OnStar Plus services including Connect Plus, Protect, and Super Cruise would be $39.99/month. That promise was never honored. Instead, I was pushed toward an $80/month plan.

Charging this much to keep a feature usable that I already paid a premium for is unreasonable, especially when the vehicle is rarely driven long distances. It feels less like a service and more like forced recurring payment.

To make matters worse, OnStar reportedly offered 50% discounts during Thanksgiving 2025 to many customers, yet I was excluded without explanation. The inconsistency and lack of accountability are unacceptable.

Customer service has been slow, scripted, and ineffective. If you’re charging luxury prices, the service should match. It doesn’t.

I also own a BMW X5, which offers better-integrated features without holding customers hostage with high monthly fees. The contrast is embarrassing for Cadillac.

Prospective buyers should get every pricing promise in writing and fully understand what features you’ll still be paying for long after purchase.

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. 😡😩😤 !!!!!
