GM Takes Away Features to Force Onstar Purchase

Capt. Action

So after two years of having a General Motors vehicle, a GMC Yukon Denali and having basic OnStar which I feel should have basic features I have had my send to navigation option taken away from the app after two years with no notice and no consideration for the fact that we own multiple General Motors vehicles.

you took away navigation from the consumer in order to force a sale of higher priced OnStar services which I feel only makes your product now look less desirable and I hope that everyone reading this will consider not purchasing a General Motors vehicle based on the heavy-handed approach that you have taken and taking away the liberties of a simple send to navigation.

I noticed that as developer you were leaving remarks back to bad reviews please don't bother leaving a standard copy and paste remark telling us about how awesome General Motors is when all you do is take away features and force people to pay for things they didn't have to pay for before.

I moved from Jaguar and Land Rover to GMC and Cadillac, I have owned BMW and Mercedes very happily. As quickly as I divorced them I will divorce you General Motors and I will go back to your German adversaries. This is an absolute shame in business ethics that you would resort to nickel and diming a simple navigation feature to try and push your ill prepared and very non-feature-rich OnStar services.

Feature removal unwelcome

Eh See 123

I didn’t complain about the significant up charge for equipping my vehicle with navigation, and I didn’t complain about the annual cost of updating maps, but I am going to complain about the removal of the ability to send address from my phone to the navigation system. This is just a cynical attempt to get people to also opt for an expensive subscription, just to get what they used to get without a monthly fee. If this is the case, my next GMC probably won’t have navigation because removing important features makes simply using Apple CarPlay a better option. Then again, maybe I should consider something with a brand of “King Ranch” instead of “Denali”.

Hands free calling

Bill the gambler

You guys tout the hands free calling as the second coming of Christ. Why does it not understand my accent. I do live in Louisiana, but have been told that I do not have a Cajun accent, and still, your Computer does not understand me. It is Feature that does not understand me. I was told to use it more, and it would get easier. That sir, is a Dam Lie. I got my truck in 2015 and still cannot use the feature the computer keeps saying “pardon”. I have gotten so upset that I now only call for a GM Rep. So that I can give them the frustration that I feel. I am now looking at the New Fords, and will be happy to drop GMC junk. I am sending this on my phone, look the number.
