Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

seems like mercedes owners have had it with engine failures while the manufacturer apparently ad known about the issue for quite some time...
humm... that remind me of something similar at Porsche... Someone says IMS
Seems like Porsche could do well by installing the LN Engineering fix proactively.
Otherwise, it may be "996 owners of the world unite. We have nothing to lose but our faulty IMS bearings."
Mercedes-Benz is reportedly facing a class-action lawsuit in the U.S. District Court of New Jersey for alleged defects in the company's M156 V8. According to the plaintiffs, premature internal wear occurs because the engine uses cast nodular iron camshafts and 9310-grade steel valves. Something about that combination causes early failure, either due to improper offset of the components or inadequate heat treating.
The plaintiffs also allege that Mercedes-Benz and AMG have known about the issue since 2007, when
Daimler released a service bulleti
n on the problem
. At this point, it's unclear how many engines this alleged defect covers, or exactly when or if the lawsuit will go to trial.
One reason we won't see a TSB on IMSBs
The funny thing is--I have not seen many AMG engine failures (from surfing the Mercedes sites). Quite a few suspension failures (at about $10K repair) but no engine problems. . .
Aftyer reading the entire claim document one can see that there are many similarities to the IMS and even RMS issue, the following comment from the board is insightful --
"The Complaint sets out the engine defect. Complete failures will be at higher mileage. AMG cars will typically have less mileage though. It's not about the complete failure, it's about Mercedes knowingly not issuing a recall on defective parts so they either deny warranty repairs or wait for the failure to come about after the warranty period when the warranty explicitly states they will replace parts."
This also "fits".
The "defect" with the 996 IMS is the use of a "sealed bearing". A jury would love hearing about that particularly when they hear that "complete engines were routinely pulled and sent airfreight back to Germany so they could investigate the cause of the problem and they tried a few upgrades over the years but never really fixed what is a totally unpredictable problem because no maintenance (or lack thereof) issue can effect a sealed bearing because the actual layout/design was inadequate so in the end they did a whole redisign as seen in the latest engine"
Similar claim for the rMS -- that is the crank not being in the middle of the "hole", or the crank not being properly supported or not stiff enough etc
There is saying in plaintiff lawyer speak "if a jury can smell it it's a winner"
Come on -- someone in the US please give Porsche a wake up call -- and do not think you would be doing "the community" a diservice because the market values of 996's could not be pushed any lower now that I read of parting out as a viable alternative to engine replacement / major overhaul
I'm very surprised that nobody has tried a class action lawsuit.
I'm also betting that there are alot of 996 owners who would shell out $100 in legal fees to get the ball rolling.
