E320 2002 doors unlock when turning hard

[Bodgit2]

I have a 2002 E320 wagon 4matic with 38k miles. It has a very odd problem-- the doors unlock when making a turn at reasonably high g force such as on an on ramp of an expressway. The lights illuminate and the doors unlock and then relock a minute later. It happens with left or right turns and is annoying.
Anyone have a similar problem?
TIA,
Steve
