It was all night heavy rain. In the morning I start the car and some weird things happening. In the dashboard showed up some lights included check engine light. Engine sounded OK but when I shut off the car, dashboard lights stayed on, headlights stayed on and the only way to shut it off was disconnect the battery.
Next morning when car dried, I start the car and everything seems OK. Only mirrors didn't close when I lock the car. The mirrors closed after I pressed the button on door.
I called to my mechanic and he said something is getting wet. He pointed some locations, seems like fuses locations, but the question is, if is it common in these cars and what most likely getting wet.
Thank you

Hello! My 2011 GL-450 started acting crazy after rain due to the ingress of water in the rear left quarter where a wire harness connector got wet. I found the water by removing the storage compartment where the first aid kit resides in the rear left of the cargo area. There was a pool of water there. The water wasn't coming in from my tail lamp seals, but somewhere higher up - I'm still searching for the location of the leak, but I've moved the wires up and keep the area drained after rain. The issue is under control but not yet fixed. Check that area.
