OnStar By GMReviews of onstar.com

Any company that forces you to call in to cancel is a scam. They hope you don't call in in order to get additional revenue. Period.

ID DO ZERO STARS IF I COULD ON STAR IS A SCAM AND NOT WORTH A PENNY!!! APP DOESNT WORK FALSE INFO AND KEPT BILLIN ME AFTER I CANCELED. THIS APP NEVER DID ME QNY GOOD FALSE INFO AND WAY OVER PRICED!! SCAM OF SCAMS DONT WASTE YOUR MONEY ON THIS BS

Was charged for a service that doesn't exist. Called OnStar and our vehicle vin, phone numbers, email address are not in their system. I have to wait to call bank to dispute the charge. Buyer beware ONStar.

Zero stars if I could. Absolutely terrible customer service. They don’t actually cancel when you call to cancel your services, and then refuse to give you a full refund. Will never use their services ever again. Do not subscribe under any circumstances!

Customers beware, customer service is terrible and shady. This company will take money from your account even when services are cancelled and hack into your account to get new credit or debit card number to continue to charge. Zero stars is still too generous.

When I bought my new SUV the dealership had me set it up to get my 1 month trial. They set it up under someone else's account so I can't cancel it but I'm the one being charged for it. And while I'm on getting charged for it, my "free" trial, I still got charged $17 & after that $44, even though the plan I chose was a basic $20 plan. Buying a GMC may just be the worst decision I have ever made, and I've made a fair few bad decisions in my time.

Horrible service! I have my data plan through On-Star. I travel often and need to have wifi to make calls. On-Star has canceled my data plan twice without my knowledge, direction or consent, leaving me stranded both times. I dont NOT trust On-Star and looking for another option since they randomly cancel me.

HORRIBLE service. I was locked out my truck and called on Star and waited over 2 hours outside waiting for help. I had to call multiple times to continue to check on service. Never again will I use on Star!
