My app quit working on the 20th of this month. Finally called onstar this morning and talked to tech. After about 10+ min. it was supposedly fixed. 2nd call and a 3rd call for a good hour and still no luck. Now they bumped me up the ladder to higher tech and they will work on it and get back to me. I also know Volt stats don't work, green charge etc also don't work but I did get a diagnostic report this morning. Anybody else have this problem and did you get it fixed? This is just one of the reasons why I have never renewed Onstar on any other car I have had. As stuff never works right and I spent to much time getting things to work.
