I can drive my Gl450 but I can’t turn it off ! Because it would turn back on for 10-15 min
Merc 450 GL , just fixed for the 6th time, (malfuction light on)new sensor put in, the suspension has never been right , rides HIGH or crooked Extremely lopsided or high only in back. it is now even higher but finally level, the floor of the car is 21" above the ground now. the floor not sill. I can barely get in. I have a second exact same car (not registered yet) it rides 8" lower at least. It is not easy to get into the car. merc just keep teling me it is fixed. .
When I even slightly turn my steering wheel when I start my car, it makes a terrible loud grinding noise. After I let it idle for 25-30 min. it stops. The car was serviced 2 months ago and steering wheel fluid was added. Is it the cold weather? It’s never happened before though.

I trailered my boat with led lights 60 miles. After parking truck with trailer attached, remote would not lock doors. After returning 8 hours later to start truck, the battery was completely dead, which is remote did not work as there was no power in truck at all. First time this has happened. I jump started car after 5 minutes of charging and drove home 60 miles on highway. I put battery on game 10 amp charger and it registered 50% full. After 1 hour it was 100% full which is impossible. Charging needle was bouncing around from 50 to 100%. Now car runs fine and never got a warning code. Is it a bad battery or a fluke, or did trailer drain battery?
