E450 All-Terrain won't move
Hey all,
Having a super weird issue with my 2021 E450 All-Terrain. So I start the car to warm it up before leaving this evening. It was about 15ºF in New York. I get inside, put the car in drive, and try to drive off. The car revs as though I was still in park. I double-check and make sure I'm in drive, then I push and pull the parking brake making sure that it is also off. I throw it in reverse, not moving. Then I put it back in drive, try the gas a little harder, and the vehicle continues to behave as though the parking brake is on (it's not) and then I hear two clunks, one after the other. Still no movement. Obviously, at this point, I turned off the car, but currently, I have a nearly brand-new, immobile Benz wagon in the driveway. Has anyone ever experienced this? It's so, so weird. I'm wondering if something was frozen?

My guess is moisture got between the brake disc and the pad and is frozen, sticking the 2 surfaces together. Perhaps all 4 wheels are so.
The clunks come from breaking the ice bonding, partially as the car is still immobile.
Maybe you can try again at the warmest time of the day (say, 2pm?).

I have experienced reving of the engine when I thought it was in gear: the problem is that I had to have my foot on the brake when I engaged either forward or reverse. I know that this seems obvious, but when I let the revs drop to normal, I put my foot on the brake and the transmission engaged.

I agree with Bishop64. I had water freeze up my brakes in 10 F. frigid temperatures.
