I can't tell you how many times I've used auto start, got in the vehicle ('11 Explorer), and touched the shifter. This will automatically kill the engine. Then I have to restart the vehicle. I don't understand why a "ding" or something couldn't be used to tell me I didn't follow the proceedures of brake and push-to-start-button, but constantly killing the engine and restarting is a little excessive to me. Plus, I usually use the auto start when it is very hot or very cold outside. When this occurs, I'm left sitting in my vehicle without the engine or fans running. I left with extreme heat or cold. Not to mention the extra strain on the battery and starter....and waste of time while everything reboots/restarts. All of this could be avoided with a simple "ding" or lock. Thanks!
