E/W214: e350 engine
M274 on the other hand was first revealed (if I recalled correctly in 2011) and the first C-Class that used it was the 2015 C 300 (if I recalled correctly), the W213 E 300 also used the same engine.
The main cause (from what I read) of the problems with cracked cylinders in the M274 engine that the 2017 E 300 has are:
A: 2015 C 300, wrist pin issue
B: M274 in general who suffered cracked pistons may be caused by a combination of: bad fuel, neglect/poor maintenance, Low-speed pre-ignition (LSPI), etc.
Avoid all MB 4-bangers. Buy a different brand if you require a new, non-preowned, car. All current MB powertrains are suspect and are objectively unreliable.
