And if you want to improve your chances with window regulators, don't slam the doors with the windows all the way down, the glass isn't properly supported by the guide track in that case. Raise them a couple of inches.

Window regulators were just an example. Oil freezing in the oil separator during cold weather, dead pixels in the instrument cluster / BC computer, automatic transmission slamming are yet more examples. Perhaps there's something that affected earlier vehicles but does not later vehicles but I'm not aware of any (save for the E46 subframe issue which appears to affect MY 1999-2000 vehicles more than MY 2001-2006). Do you have any examples?
