M274 Engine Causing You to Bail?
#126
I have a 2016 W205 4Matic Sedan with the ubiquitous M274 2.0l and it’s been nearly Toyota reliable for me. I’m currently at 141,000 miles and I’m just now doing my first somewhat major repair. My car is in the shop for a failing oil pump and its second failed PCV valve (these valves crack over time). Only other repairs I’ve had to do were a A/C sensor & PCV valve at roughly 70k miles. I’m averaging about 530 miles per fill up, I plan to keep it until the wheels fall off.
they actually sent out a letter to everybody regarding this issue with the valve the PCV! You can actually get a refund for it because now they extended the warranty so I would call the dealership and ask if you are eligible to receive a refund there’s someone else who received a refund as well for this issue.

thanks for following up. It turns out my oil pump wasn’t failing, my M274 is still using the original oil pump at now 148k miles. It was just the PCV. My mechanic had me to the one he installed at 70k over to the MB dealer parts department and they did warranty the part..

Heartbroken
Between the wrist pin issue and #1 piston cracking issues with the M274 engine (2.0 4 cyl gas), my level of confidence in the longevity of this engine is low.
So I'm wondering how many of you are considering selling or trading in your W205/M274 (or already have) based on these engine issues?
Myself, I'm close to that point. I love my C300 and have poured a lot of blood, sweat and tears (and a large pile of money) into my car, but I find myself constantly concerned that today is the day my #1 decides it doesn't want to play anymore.
I'm currently at 51K miles and it has been a great car so far. However, I'm becoming weary of worrying about how much time me and the engine remain friends.
I'm planning a ~3000 mile road trip in the coming months and I'm considering renting a car for it and that's just not right. I should be able to trust my car, but I really don't… unfortunately.
So how many of y'all find yourself in my position?

Hard to believe no major aftermarket supplier has a drop in forged piston solution yet.
Upgrading pistons before they grenade is going to be cheaper than doing it after!
