I don't believe this is correct as this particular failure is being reported across the board and not just in the U.S.
I don't believe this is correct. I gave the service bulletin to my local dealer he specifically mentioned that this is for US built cars. I am also a member of a local W205 club we share many issues across the board and propose solutions. No one ever mentioned a piston failure or wrist pin issue. If it was commom at least one owner should have mentioned it. All cars around here are German built including mine.

Interesting. If I remember correctly, some of the owners reporting the problem in this thread I don't think are U.S. based. Since 2.5 million W205s have been built, how wide-spread this problem is, I have no idea.

Yeah I know quite bizzard. This is serious and embarrissing to Mercedes wether US based or Germam or wherever. They should have issued a recall. I mean look at the OP why does he have to pay for a new engine when his car has only done 65 K. What is Mercedes USA doing about it other then issuing a service bulletin?

MB is doing nothing about it, because they don't care once the car is out of warranty. Actually, they don't care when it's IN warranty either! This is a good lesson to buy an extended warranty if you can't afford the repair costs of an older Mercedes, or, stick with a brand you can afford.

I agree that MB should make good on this as the service bulletin does show that MB is aware of the problem. Those customers effected by this defect really should file complaints with NHTSA because if enough complaints are filed then NHTSA will get involved and make MB address the issue. My guess is that hasn't happened yet. It used to be that MBs with 100,000 miles on them were considered barely broken in and that's still true for the older models because they were built like tanks. People shouldn't have to buy an extended warranty to cover such a low mileage failure. I agree that the ball is in MB's court.
I agree with E55 and 190E, and to file a complaint. What this will show, is the tip of the iceberg of MB's atrocious quality/reliability. Recent MB vehicles are expensive garbage, and the piston cracking situation is only one of many recent examples. Owners may pipe up proudly and claim to not have had a single problem with their MB. This may either be true, false (a lie) or luck. I'm leaning toward such claims as being in the latter two categories.
Full disclosure: it's possible I may buy another MB in the future. The difference for me, however, would be that I have my eyes open and know what to expect in terms of MB's terrible quality. I was taken aback by how bad MB's quality and reliability are, when I started to become familiar with common issues on these cars over the past 5-10 years. It's failed engineering and kindergarten-level mistakes that MB is making. It's also true that I am not a brand zealot and other brands (BMW, Porsche, Audi) are equally well positioned to earn my next vehicle dollars.
Thank you guys for the comments, I have been researching and just on NHTSA there are 20 cases of broken engines. The bulk of those complaints are just starting to appear over the last two years, people are just turning 50-60K miles and the issue with the engine is getting more visible.
I've also received MBSD Quote for repairs this week and what makes me mad on it is "description: 2015 C300 AWD with 65K miles needs new engine" and everyone is acting like it is normal thing ....I've owned Alfa Romeo, Fiat and Yugo but I never had to replace engine on any of them. My mechanic was telling me that he wanted to get this car for his wife and just in past few weeks he had two cars with same issues. Problem is MB is using this platform on many other models.
Here are two options that I have:
Option A. Refurbished engine $10K+ Labor $5K with discount = ~$14K would have 5year 40K miles warranty like a new car
Option B. Open existing engine replace pistons $3K +labor $8K with discount= $11.5K
Option B 8,000 usd labor? Sounds too much. Another quote from another independent mechanic will be very helpful. I mean people go to independent mechanics to save money. Make sure you get a warranty as well for option B.
Recently had a misfire on the cylinder 3, took it to the dealership and they say it will cost $20K and it needs new engine!!!! Had this car for past 4-5 years and have been enjoying it, just turned 65K miles. The other day on a freeway it started stuttering and check engine light came on. I have been babying it and never went over 5000 rpm.
San Diego MB dealership told me cylinder 3 wall is scratched and if i pay $9000 they will pull it apparat to see what the damage is, or just swap the engine for $19000+.. They suggested if I can prove that I did oil changes on time they "could" give me a discount! Once I did that they told me it was not done in their dealership and I am on my own.... I see online that I am not the only one with this issue, cracked piston ,wrist pin etc...?
Yeah I have been looking at that but still labor will be more than that core and no guaranty of any kind... So I would spend roughly $10K and if I decide to sell it I would get $20K in best case scenario.
Option B 8,000 usd labor? Sounds too much. Another quote from another independent mechanic will be very helpful. I mean people go to independent mechanics to save money. Make sure you get a warranty as well for option B.
I do not think warranty will be accepted if my independent MB mechanic does the work. They were giving me hard time just because he did my oil changes even though he has MB license....

I am referring to a warranty from the independent mechanic. Imagine you spend 11 k usd but no waranty from him? What if he did a bad job? I recommend you let one other mechanic give you a price 8 k usd for labor i think is a lot. I know its a big job but still.

MB agrees to replace engine at their expense
Took a while (3 months) but MB finally agreed to repair their 2018 M274 C300 engine (Cylinder 1 failure at 13,000 km) at their expense approx. 12 hrs after I called head office in Germany and after ghosting my local dealership in Australia for weeks on end. Fortunately I did not need a car. Note, I never received a reply from Germany.
Shortly after agreeing to repair my car they advised they needed to replace the engine (also at their expense). A courtesy car was included the same day as they began their works (2 months). Not a sorry or anything of the kind when I picked it up, it did not even get the standard car wash.
What now annoys me is that what I thought was a "New Engine" is in fact just a "Long Block (in which the entire crank assembly including the cylinder head, valves, injection and much more have been completely overhauled and installed using only MB Genuine Parts), compared to a New Engine or New Basic Engine or Basic Engine or Long Block Plus. In short Long Block replacements are a “remanufactured engine” that does not get tested on the manufactures test stand before been sent to the dealership. You can learn more about that at b2bconnect.mercedes-benz.com/gb/products/remanufactured-parts/cars/engines/basic-engine
Even more annoying is that the this Long Block from the "new engine number” 454,306 provided appears to have been produced 86,479 before my failed engine “540,758" OR approx. 47,704 after MB modified their faulty wrist pins that were installed as of engines in 2015 engine number 274 920 30 406 602 on which leads me to believe this engine may have been produced in 2016-2017 ?? As well as the wrist pin issue, I feel its just MB pistons are sub-par mass manufactured rubbish. They have to have a flaw in them too ? Maybe the M274 just needs some aftermarket forged pistons.
Someone please correct me if my understanding about the engine number is incorrect.
Anyway its now been 5 months and with 2,002 km on the engine and is already more noisey on cold starts that the original engine. Transmission also notably louder. I don’t know what to do, I just know I don’t trust this engine, or MB and I will never buy another MB again. Is it all in my head or should I flick it.
If you are interested in what a new m274 long block sounds like with 2,002 km you can download my videos at recorded on a iPhone 101a M274 2018 Cold Start 3m 30sec - 37-40 deg celsius.mov https://www.icloud.com/iclouddrive/0...40_deg_celsius
No warranty was offered on the new long block as it was done under warranty.MB also returned it with a broken PVC line (crank case vent line) and a torn aftermarket pod air filter. Fortunately as soon as I drove it the 2k drive home I inspected their workmanship. Had I not caught this vent line it would not have been too long before I was back for another engine replacement.

Hi chassis, they want me to pa $9K just to pull it apart to see if indeed is piston/ wrist pin. What they did was they checked compression and via spark plug hole they looked inside and saw scratched wall... So most-likely it is piston. Mechanic told me with this new injection system sometimes computer adds more gas and it is possible to have secondary explosion that cracks piston.... I do not know if that was a reason or something other... will keep you guys posted. Still looking into other options.
I've always wanted to know how to capture the sky with stars like that. Does it require being in the boonies away from city lights, on a high peak and using long exposure? (I suppose I could google it)

Hi Benzdue, that is exactly how my conversation with my dealership started for my 2018 C300 at $13,000. I was quoted 8K after they pulled Cylinder 1 sparkplug and had a look inside with their lenses. 1. they already know the problem, 2. paying to diagnose their own product is utter madness, 3. I feel this is a trick they use to cover some or all their costs IMO See my original post.

Sorry, about your troubles. $20k was exactly what i paid for my 2015 CPO with 16,000 miles on it. All these stories make me nervous, but i love my car.
The MB dealer you went to is not giving you correct information. All MB dealerships work on all MB cars regardless of where they're purchased. Federal law states that ou also don't have to have your oil changes done at an MB dealership to get help. I suggest you try another MB dealership.
The federal law you are thinking of is for warranty coverage only. He has no warranty. They are perfectly within their right (although it sucks) to not help the guy out if he didn't get services at that dealership. They can make whatever criteria they want when it's not warranty.
The law you refer to states that anyone can maintain a car under warranty and the warranty must be honored as long as the services and parts meet the manufacturer standards. No warranty- no legal protection.

Hopefully nothing bad happens to yours, your car has some very uniquely yours mods, like forum member Keith66.

Did you ever get your car fixed? If so which option did you end up going with?
