on thanksgiving, i went to get into my truck and the car alarm went off and i hit disarm, but for some reason it didn't deactivate it, and i went to turn on my ignition and it initiated the engine cut off and went apeshit. and then i sat there trying to fix it for a long time with the manual that sucked ass. that was a horrible day. i had to go online to find out how to get it out of the cut off mode
