When ever a car starts to do crazy stuff like turn its own radio on, switch its headlights on and unlock itself at random, you need to look at the body computer. This controls all those functions and many more and, when it starts to fail, these phantom symptoms can start to surface.

In some cases, you may need to replace the body computer, but there’s a free hack you can try first. Disconnect the car’s battery and leave it overnight. Reconnect it next morning and see if the symptoms disappear. Sometimes, this trick will reset the body computer and all will be well. The effect may not be permanent, but it’s free and definitely worth a shot before spending money.
