Here's the list of reports that I consider reliable, having good service records, regarding unmolested OM642 engines:

On another topic, with the same criteria, (actually I'm just bringing it back to the original topic of GLC 300), here's my list of reports that I consider reliable, having good service records:

I'm just listing the credible reports I've seen.
The list of SUBstantiated "failures" I've seen is also zero.
I have only seen an occasional reference to other UNsubstantiated rumors.
So, a more direct reply to your implied question is "What failures?"
It's not my thing to catalog rumors, but every one I've looked into has caused by a bad repair, or reuse of single-use parts.

All my brand certifications have expired.
Also my factory service and ASE certs.
Hoping to sell at least one roll-away tool chest to someone who will use it well.
All I have left is knowledge, subscriptions to Industry Rags, and my contacts in the industry.
My only claim to notoriety is that I was in the first class of 12 technicians who received the first emission certification in Colorado.

It will be interesting to see if the class action expands to the M264 and M254 engines because of their genetic heritage to the piston-cracking M274.

It'll be interesting to see if that firm can assemble enough complainants to proceed.
It'll be a better indicator of failures than the few that are actually reported on these forums.

I have a 2016 GLC 300 4-matic that I loved, until last Friday. I drive a lot of long highway miles and take immaculate care of my vehicle and perform all suggested maintenance. While driving home through a very remote stretch of highway, my GLC suddenly started shuddering. No smoke or loud sounds, just shuddering. I pulled over and popped the hood, like we all would do. I saw nothing out of the ordinary. I tried restarting it and the idle was low and vibration was still there. I had a 2 hour tow (thanks to MB roadside service) and made it home 5 hours late. The local dealer in Bend, OR (great guys) said the piston failed and was ruptured on the top edge and the engine would need to be replaced. It is about a $12k fix. I'm out of warranty, but am flabbergasted that a 2016 with 66,000 miles on it already failed. Does anyone know if this is a common thing with this model, or year? I'm wondering if the fix is worth it.

Yes, I very much wish that those who received help/compensation from MB would share what tactics/strategy worked, or what deciding factors made the difference. I'm helping my sister with her 2016 GLC300 that had piston crack at 49K miles. I've been perusing the forums and 80-90% of those with the issue appear not to receive help. But 10-15% do, and I would like to know what made the difference, but so far they've been very reticent to share and I'm not sure why. The only advice I've seen is to be persistent, which we have been, but it has not gotten us anywhere.
The only factor that could be a deciding factor is whether all regular service was done at the dealer, which was not the case with us (largest independent service center in the area), and has been held against us as another factor. Very frustrating to say the least.

A suggestion is to lawyer up, especially if you can present maintenance documents to the dealer and no progress is made.

its true for any dealer, mfg doesn't want to pay, and dealer wants to make money doing services telling customers it must be done by certify techs, who cares less what and how much oil to put in your car. Dealer makes 80% profit by doing services and only 20% comes from sales.

Here is a good explanation, its a federal law, if you have receipts, and work was done, they just cant deny coverage. Most people just don't know, and do trust advisers,

However, dealer profit is typically divided 1/3 each - Sales, Service and F&I.
The past year has been different with the shortages and markups, so the past year it's been 1/2 Sales, 1/4 each - Service and F&I. Reverting back to 1/3 each the past few months.
Also it's important that Mercedes pays (reimburses) essentially full retail rate for warranty claims, so they don't hesitate to do those repairs. It's money in their pockets.
Many manufacturers do not pay retail shop rates, and those dealers are more reluctant to dig deeper into a warranty complaint.
It's a really large advantage for Mercedes Owners.

The trouble with "emissions warranties" is that the EPA never formulated Rules to measure performance or compliance, so as long as the emissions equipment is present and operating, there's no violation. "Operating" is vague by EPA regs.
Bosch "et al" (most Euro manufacturers) sued the EPA twice - 2012 & 2016 - about "no regs" and won at the US Supreme Court, but the EPA never complied.
A big hole in enforcement.
It would be interesting if a Firm could find a way to cover piston failure under emissions, but I think it would be a stretch.
Especially since there hasn't been a recall.

c300
I purchased a 2017 C300 class Mercedes-Benz ("MB") in May 2021 from a used car dealship in Mobile, AL. At that time it had 36,000 miles. Less than 2 years later, on or about 12/15/22, as I was driving, the MB suddenly and without warning began to vibrate violently and immediately lost power. The car had @54,000 miles on it. I routinely drive interstate to and from work and had just gotten off of the interstate. I was lucky that I was driving at a low speed when this happened; otherwise, a serious accident could have resulted. The local MB dealership told me that the car failed a compression test in the #1 cylinder and that the engine would have to be replaced at $20,000. Of course, this was beyond warranty, washing its hands over its defective product, refused to act responsibly and replace the engine. Subsequent research on the cause of this total engine failure with low mileage relvealed that this engine has a chronic piston defect that damages the #1 cylinder, causing it to lose compression, and that MB has known about the defect for many years prior. MB has not alerted the public nor instigated a recall. In my pre-purchase research, i found no information from MB that the C300 class engine (M274) had a chronic piston defect that would damage the #1 cylinder which would, in turn, cause the the engine to lose power and the vehicle to vibrate and shake, creating a dangerous diving condition under all circumstances, but especially if the car was being driven at speed on a federal interstate highway. Despite demands by me and others, MB refuses to responsibly address the issue. MB prefers to allow this condition to exist so that the defective engine will get beyond its warranty obligations. In my opinion this is outrageous conduct by MB. The driving public is clearly in great risk of harm due to this defective engine and associated power train problems and MB is putting its profits over consumer safety and doing the right thing by this defective engine. It is patently unreasonable for MB to produce and market such a unsafe, dangerous and defective product that poses an unreasonable risk of harm to its customer and others, and causes significant economic loss to its customers. MB clearly putting profits before people. This car is crap and anyone thinking of buying one should run away as fast as possible. Buy a Lexus instead. I am trying to put together a portfolio of aggrieved MB customers to pursue a class action similar to the one currently pending in California. If interested to participate, please respond to this post and I'll make arrangments for contact.

Since @Westlawn1968%% seems to be fixated on pasting the same tale multiple times, I'm pasting my earlier questions to one of his/her/it's pastes:
If there were as many failures as are referred to by those folks, why isn't there a recall? I had a recall on a trim piece (it was fine) but maybe the NHSTA didn't find any damning evidence.
@Westlawn1968%% this is the fourth time you've pasted this here and there on the Site.
Is it a true story, or are you a lawyer trying to recruit for your lawsuit?
He she it gets "likes" from the usual suspects, who also haven't been able to provide any specific instances.Is it a true story, or are you a lawyer trying to recruit for your lawsuit?
