Until I saw the above posts I thought I was crazy. My 2010 MKX has also tried to crush me 4 times so far - but only when engine is in park. My dealer tells me Ford states it is not aware of this problem but has recommended some tests and I have to leave it in for a day next week. I am also a BIG guy and assuming I survive I will report back.
My motorcycles do not have memory seats.
My dealer's manager couldn't stop laughing. It is funny, isn't it?
