I think a class action against BRP to have them uphold warrantee commitments to existing owners might be a good strategy. I was trying to research US law and there may be an obligation if the new owner to fulfill commitments of the old owner - even suppliers seem to have a possible commitment - 40 CFR § 1037.620 - Responsibilities for multiple manufacturers - starting point?
Really need a lawyer to weigh in on this but thinking we have an argument that BRP may have product support and warrantee commitments.
