Yes, she settled with DMCH. Here was the essence of the agreement as written in the District Court decision in the dismissed second lawsuit:
"First, the Settlement Agreement is not merely retrospective. Instead, it both resolves all claims that were sought and could have been sought in the 2014 action and recognizes DMC Texas’s rights to use these marks in the future. Those rights, as explained above, include the enforcement of DMC Texas’s marks and licenses to those marks. Second, the Settlement Agreement expressly carves out specific areas in which the Estate retains its right to pursue legal action against DMC Texas—namely, any other use of the name DeLorean, any aspect of John Z. DeLorean’s life, and any depiction of his likeness. That the Universal Agreement is not mentioned in the Settlement Agreement suggests that the parties did not intend to permit the Estate to be able to sue DMC Texas for attempting to enforce its rights to the marks against other entities, including Universal. Accordingly, we find that the Settlement Agreement shields DMC Texas from suit brought by the Estate for the conduct at issue here."
