My experience was not exclusive to length of warranty but applies to any AEM disputes.
I hope you can understand my confusion because the only thing you stated was your experience getting your warranty coverage increased. That is a matter of exact dates and clearly spelled out verbiage not really a "dispute" other than the dealer could not do math. The information you have provided does not provide a precedent for overturning a dispute regarding vague terminology and open ended terms for what parts are covered. Which again, see below, does not even apply here in the first place anyway since the defective part is NOT KNOWN.
The lawyers have been paid to remain in the loop and assist when called upon but by all means have at it.
And again, what assistance can they be called on for? You are advocating for legal intervention to enforce a contract yes? That contract (as are all contracts) is specific and apply to certain conditions and in this case parts. I am merely pointing out that I do not see how you would expect a lawyer to argue to enforce a contract without the specific item wishing to be enforced being known. It is impossible to argue that a component qualifies for the warranty when you don't know
what that component is.
Lawyer: Judge, I request you rule the defendant uphold this contract for defective parts.
Judge: What part is defective and where is it in the contract?
Laywer: Um, I don't know your Honor......
Sounds good, totally don't see that judge throwing his gavel at that guy.
I have no idea why one would want to skip to step 3 without taking the time to do 1 and 2, but you have at it.......
