This evening, my wife's 2000 ML320 decided that it enjoys unlocking and relocking its own doors. I used the remote to lock the doors and heard the doors lock, then unlock and lock again. I unlocked it and tried again. Same result. The worst of it is that every time I come to a stop and get to the speed where the autolock feature kicks in, the doors unlock and then lock again. It does it on EVERY stop!!! Insanity.
