I’d say that if you had problems with the wrist pins you would know for sure by now. The M274 is a direct injection engine. It is loud and sounds almost like a diesel. That is perfectly normal.

I checked the production date it says December 2014.

You should be good. The issue, Topic number L103.10-p-060916. Affected engines production 920.30.406602. (27March 2015) through to eo-043259 (20April 2015)

Green, this has nothing to due with the age of the vehicle...It's all about the miles.

Waking this up. Has anyone had anymore engine replacements or problems?

My 2016 GLC 300 is currently getting a new engine because 3 pistons cracked! They wanted $11k to fix it, but after I told the Mercedes service center that I'm going to do some digging because this is not normal for a car with only 40k miles on it, they said that I can have the engine for free and that I only had to pay about $4,500 for labor. While that sounds nice and all, I'm still going to report this issue to the National Highway Traffic Safety Administration to see if a possible recall can be initiated.

I haven't heard that one yet. Yours has the engine made in Tennessee in collaboration with Nissan. Good luck. I know Subaru has had some engine failures over something simple...like oil sensor parts separating and falling in the engine.

Nissan: French quality with Japanese flair.

Just got quoted $11,500 - 14,000 to fix a cracked piston in my 2016 GLC 300. Dealer said they will contact MB Corporate to see if they'll show some mercy.
