Man o man !! that cant be clearer there is so many way for a car manufacturer to get out of trouble that its not even funny.
In conclusion no matter what one can do, we are always screwed
Anyways thanks a millions for your time , it was a really interesting response to my question.
Lets add a degree of complexity (and cost)
Lets say your "expert" says it "is" a defect in the engine. ( it would have to be a defect otherwise the OEM wouldn't be liable in most cases regardless once it leaves their control)
You will have to show whats defective and how it killed the engine- then you have to show it was somehow a defect in design, material or part.
That's very hard to do (and expensive)- then you have to provide all that data to them for their review and cross by their experts.
All of those billable hours keep on adding up.
Then, even if you win come the appeals.
Ask the McDonald's coffee woman the difference between what she was originally awarded versus what wound up in her pocket and you will get the idea.
