The panaramic sunroof had gotten stuck open and gears or something are not engaging at times, sounds like motor grinds and the sunroof slips off track and closed unevenly. Will not open back up.
This creates a serious risk of fire or explosion. Unfortunately, Mercedes does not offer a remedy unless you pay a prohibitively high fee.
no warning lights showed up but it is a common problem on the E-Class due to a cracked fuel filter housing module.
In the fall of 2021 the car started to received errors related to the ABS control unit that failed preventing 1) antilock braking, control of ESP (limiting poor handling), and cruise control. At the time of the failure, the car only had 31,552 miles and was properly maintained.

After fill-up, I noticed a faint fuel smell on the drivers rear area near the rear wheel. I have also opened up the access hatch and noticed fuel seeping from the sending unit. This seems to be the exact issues I have seen in regards to [ref]. This smell goes away after the tank level goes below 3/4.
I was driving on a city street and a red indicator light came on telling me stop car too low. Car was in sport mode with the vehicle raised button indicator light on. I drove back to my house and parked the vehicle, as it sat for an approximate 1 hour I noticed it drop significantly.
