Are all headbolts on 09-10 C63 going to eventually fail?
I am in the market for a C63 but the whole head bolt failure issues points me in the direction that I should shoot for an 2011 or up.
Is it inevitable that the older designed bolts will fail? Or is this happening to modded cars only? I plan on keeping the car stock... tune at most... but not if these bolts will fail.

no one seems to have a definitive answer to this question. the issues with the older bolts led to MB to change parts mid production. yet, there are plenty of 08-10 owners that haven't had an issue and there is no full recall yet.

My vote is this:
If you look at it from the mb's standpoint, it needs to make financial sense to do a recall. If too many engines fail, it costs mb more to repair after the failure than before, so mb may consider a recall. Otherwise they would repair each incidence under a tsb. Conclusion: at this point probably very few 156s are failing.

From the VIN, someone with STAR TekInfo access can get the engine number. From the main thread on this issue (https://mbworld.org/forums/c63-amg-w...oncerns-2.html), there is this:

Its rare. My local dealer hasn't had one fail at all.
I wouldn't be overall concerned about it.
The price of replacing with ARP head studs is not cheap, thousands. The parts alone are 900$ Labor probably $2500-$3500
I have a spare engine if you hydrolock yours
In reality, guys are seeing coolant loss, aka coolant is seeping into the cylinders and being burned off. It would take about 100cc+ of liquid quickly entering the cylinder to hydrolock the engine.
If you are seeing the low coolant sign, you have a serious problem and need the headbolts replaced immediately.

My car has a build date of May 12, 2010. There are about 1000 engines between mine and the last one before the new headbolts were installed on all '63s.
I won't own the car out of warranty because it is within the range. If I were buying one used I would only consider a CPO car with an extended warranty covering the whole drivetrain.

That's complete bullsh{t
An engine does NOT lose coolant unless there is a leak. If there is no leak, the engine is burning it and there is a head gasket sealing issue.
I would fight this with them as they are just shoving you off and hoping it doesn't fail while the car is under warranty.
There is a bulletin in Canada for cars burning coolant now I believe, check around for it and educate yourself.

I just had mine into the shop today on suspicion of having this issue. They couldn't tell me anything about it. They topped off my coolant and sent me out.

It's unfortunately the owners would have to wish for the failure to happen soon so at least it will be covered under warranty. Well, I guess it gives me a reason to trade it in for another vehicle before my full 7 years warranty runs out.
Gosh, I'm gonna miss the last N/A AMG engine (not counting the SLK55).

Please have him inform us as to what those warning signs are other than coolant loss. I'd like to know.

Exactly....mine had the head bolt issue and there were no signs at all. No leaks and no loss of coolant. It happened to me on the highway just when I started to push her hard and all of the sudden puff of white smoke...looked down and my car was in limp mode. Got it towed to the dealer, $20k later I have a rebuilt engine courtesy of MB Canada.

After more research, the headbolt is technically be considered a fastner, which is not covered by Fidelity Platinum or MB for that matter. If you have a good relationship with your service advisor and kept the car up, MB may be willing to help you out.

Not covered by MB, either? Then what's the point of getting the factory extended warranty? Might as well use the cost of the extended warranty to pay for the elective head bolt change.
