It will eventually happen.
And you may have some success with the lawsuit.
I have a 2001 Dodge 2500 with the Cummins diesel. There was a known issue from 98.5-02 where if you had a "53 block" (you can google it) you would likely end up with a cracked block. The casting on 53 blocks was incorrect (Cummins outsourced to Brazil I beleive). People had failure after failure after failure for many years. Finally, enough folks banded together and sued. I received a class action settlement notice in the mail. I didn't buy the truck NEW, so I didn't qualify, but it was still sent a notice sent to me about the settlement.
If you are serious about starting a class action - then get serious about it. Actually contact a law firm. Most likely, the first thing they will tell you is the same as the first rule of fight club.. If you're going to sue someone, you don't freaking talk about it. Especially on the internet. Wait until they open a call for other owners to JOIN the lawsuit. Honestly, since you are an original owner... you probably have a better shot than most.
