2016 GLE electrical issue??
I took my vehicle to the dealership in for a recall fix and this problem happened shortly after my visit. Has anyone heard of this problem before?

Sounds like a gear shifter module or a bad conductor plate (built in speed sensor) and the plug got soaked in oil. Something to check out. The Conductor plate sit inside the transmission pan. I know on the older Benz the plug is inside the front passenger floor board. I have not checked if it's in the same location on the GLE.
As for the recall it's for the steering I had that same recall way back and MB took care of it at the same time they did a map update.

It seems like a good maintenance item, to remove the heat shield, disconnect the electrical connector and inspect the connector for oil infiltration. Presence of oil may be able to be cleaned by contact cleaner, although likely a temporary (years?) fix. If there is oil in the connector it would be due to seal failure of the connector and replacement in my view would be needed.
Oil in the 722.9/W166 connector doesn't come up often (yet) on this site.

This has to be re-program on STAR tool. The 5 speed does not need to be program.
