I have a 92 900 S Turbo with a manual transmission and twice now I've had someone else that's driven it and didn't realize you had to put it in reverse to take the key out. Both times, after asking me, they did put it in reverse to remove the key - but shut the car off with the transmission either in neutral or another gear (I didn't ask as it wasn't until it happened the second time I realized this may be an issue). Anyway, both times right after that happened I lost so much charge on my battery my alternator wasn't able to keep up and my car died. Is anyone else having this issue? Is this something common or is it a possible sign of a bigger issue? Thank you!
