E300
e350 engine
i now have a 2017 E300 with 50,000 miles. This engine, along with some E350s in recent years, have occaisonally suffered a problem with a piston dropping into the engine and destroying it. I’m not an expert so my description may not be technically correct. Does anyone know if this has been corected for the 2024 model or whether it’s still a potential issue?

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.

Today’s car uses the M254 which is descended from M264 and M274. All engines have bad genes. The failures reported in this site are not from user neglect or bad fuel.
