SERIOUS ELECTRICAL GREMLINS - DESPERATELY NEED HELP

My 2011 Bluetec has developed some crazy electrical gremlins. The following list of things all go out together as package deal: turn signals, horn, washers, high beams, power steering wheel adjustment, cruise control inoperative, tire pressure monitor inoperative, SRS warning light comes on, can't shift E/S, can't turn off traction control, radiator fan comes on high. (think thats everything)

I have spent $2500 at the dealer to replace various control modules they thought must have "gone bad" to no avail.

Anybody have any ideas at all?

Thanks,

Have you checked ALL of your fuses?

I had something very similar that knocked out the radio/satellite radio module. It was due to water intrusion in the battery compartment coming from the firewall.

They replaced modules, charged you for it, but the problem was not fixed? None of the changed modules fixed anything? Something seriously wrong with your mechanic and dealer. Escalate...

Is there any update on this? I work at a car dealership and we have a 2011 R350 Bluetec that I am thinking about buying, but it is doing the same thing. Except once the vehicle shuts down it will not start back up for quite sometime. A warning light will start to flash that says to drive to a dealership without shifting gears.
