Ratings and reviews

For 13 months I've cursed the MyChevrolet app. Slow, unreliable, countless errors, etc. Last week I stood beside my car and used the app to unlock it. The process easily took 3 to 4 minutes. With all my vehicle software updated this week, unlocking took just under one minute tonight. On Android, the MyGMC app is a newer version than MyChevrolet. With that app installed, unlocking my Blazer EV took less than 10 seconds. I've switched to MyGMC.

Just like everything with my GMC Sierra Denali ultimate, this falls short. Constant bugs, works most of the time but when it doesn't it's always at the worst possible time. I just missed a dinner reservation to a high-end restaurant because the app kept failing to unlock my car. I had to clear cache and then totally uninstall and reinstall the application to get it to work again. Truly unacceptable.

This might be the buggiest app I've ever used. Consistently shows "unable to load" on vehicle diagnostics, frequently crashes, and today I can't even use it. It forced me to sign out and back in because it couldn't load my account and now it won't even give me the option to sign in again. It just keeps giving me the "try again" message every time.
