My remote start doesn't work at all. Every time I try it the alarm (honking horn) goes off.
Another forum member says that no matter what he does when you try and "start" the car once you've started it with the remote start, the engine stops when you put your foot on the brake. Evidently when he pushes the button it kills the engine too. Then you have to re-start it in order to drive way.
My Cadillac had remote start and push-button. All you had to do was push the button and you were good.
My F150 also has remote start. If you step on the brake the engine dies. However, if you put your key in the ignition and turn it you're good to go.
I have an appointment on Tuesday to have the remote start looked at. Assuming they fix it, I'm still not happy with having to start it (remotely), then shut it off, then start it again before driving away. That's pretty messed up. Especially when you consider how long the MFT takes to get going, and the extra battery power it takes to crank the car over, etc.
