M264 Differences
M274 piston failures on this site are reported on C300 (well documented) and also W213 E300: https://mbworld.org/forums/e-class-w...ml#post8246209
Where are E300 M274 engines assembled?
The GLC300 also uses the M274 engine.
The M264 shares many components with the M274, notably the crankshaft and connecting rods. However, the piston part number is new for M264. Whether it is a modification of the previous M274 design or a clean sheet new piston design, is unknown.

An adjuster is looking at it then I will know exactly. But it’s a making a knocking noise and Mercedes is suggesting a complete engine block replacement. I have the M264 in 2021 GLC 300 4Matic Turbo Coupe 52k. Please provide any thoughts??

according to the vehicle quality network data,
the main problems of the C-class are
concentrated on the engine motor failure and
the engine failure light., The engine shakes and
cannot start.

I operate a specialty shop in Kansas City (Royal Autowerks) and just bought a 2016 C300 with 68K on it from a client with the loss of compression on cylinder #1 and will perform the detailed teardown (and rebuild ultimately). My client has registered for this class action lawsuit. I recommend that anyone that has had the same concern, reach out to the CA law firm that is pursuing the class-action suit.

I am a former Ford engineer and MIT mechanical engineering graduate (Masters and Bachelors). I have also been a mechanic for 39 years. I have engaged the law firm and will likely end up being the engineering and mechanical expert on this case.
I encourage you to get registered for the suit if you have suffered a loss. Do this before you dispose of the vehicle.
