I started out this morning in my 2013 GL450 which usually runs like a Swiss watch. It was 25 degrees outside, which i've never driven this rig in temps colder than about 40 degrees. Drove about four blocks and suddenly loss of power and I probably had about two horsepower, and the message on the dash came on (see photo). Obviously there must be a sensor that does not approve of being driven in this cold. However, there are millions of vehicles on the road that are not having an issue even in this weather! Or colder! I feel about 100% sure that in a day or three when it warms up back to 50 degrees, it will be fine again. I was able to pull over, restart the engine and it seemed okay again but I did turn around and get back home and park it just in case. Anyone have any ideas what could be the matter? I can scan for codes but will wait a few days till it warms up! LoL.
