Piston 1 cracked while driving on the highway. My sibling was driving on the highway when the engine suddenly started misfiring and losing power because it lost compression on the piston that cracked. I was lucky enough that I have mechanic experience to replace all the damaged components myself and paid out of pocket. I was super fortunate that the cylinder walls did not get damaged when this happened thus not needing an entire engine replacement which would cost around $10,000 from mercedes. I had to go pick up a trailer from UHaul and go pick up the vehicle from where it broke down. Thinking about this from the perspective of a person who does not have access to rent a trailer, a vehicle to pull said trailer with, or the mechanic experience to fix the vehicle themselves, the cost to get this issue resolved would be much much more than it cost me.

I was unable to put the car in the drive after pulling out parking spaces or any other instance where the car needed to move. When attempting to put in drive, the car would revert to neutral and drift. Leaving me stuck in the middle of the road or parking lots. Check engine light came on briefly after the car wouldn't go in to drive but disappeared. Took it in to dealer immediately and they indicated that the transmission valve body control unit had failed and needed to be replaced. The car has less than 60k miles.
