After 7 years of absolutely flawless performance awoke one morning to severely low battery.
Attempted to troubleshoot to find source of phantom electrical draw, but could not. Apparently these seat modules become intermittent and randomly draw current.
I merely disconnected the seat modules.
There is a "fix" where the constant power/memory lead (which allows the seats to be moved with the ignition off and for seat memory positions to be remembered) is disconnected from the battery hot lead so that the seat is only movable when the key is ON and the alternator is powering the vehicle. A minor inconvenience, but avoids over $1200 in module replacement.
