Paul-2018AMG

About 3 hours after a short trip to the supermarket - went to the garage to take the AMG on another short trip. All headlights and tail lights were on - vehicle not running. Could not turn off any lights. FOB did not turn on or off the car - no interior lights came on when I opened the door. Nothing - car totally locked up. I quickly changed the batteries in the 2 FOB's - didn't help. Tried to start the car with the FOB remotely - tried sticking it in the key slot - nothing. Depressed the brake - you can tell nothing is working - no travel in the brake pedal. The Vehicle batteries are both changed out 2 months ago. I have the trickle charger going - doesn't seem to charge. Door lights will still not turn on when I open the door. Vehicle is brain dead - think it must be something to do with the computer - anyone else had any sort of issue like this? Car has been fantastic until Friday evening.....Car has 67,000 miles - did all the service at Mercedes - never an issue other than tires wearing out quickly....

Disconnect the main battery negative terminal for a little bit to start. Inspect for water intrusion specifically at the SAM units, I believe there’s one in the trunk behind passenger side tail light area, under the rear passenger seat area, under the glovebox.

might be helpful to post up in the GLE forum also.
