    December 2018: Judge Denies Motion to Dismiss Georgia Mercedes-Benz Mold Case

    On December 18, 2018, Judge Amy Totenberg of the U.S. District Court for the Northern District of Georgia denied Mercedes-Benz’s motion to dismiss the vehicle mold defects case, finding that the plaintiffs’ had sufficiently plead their claims against the luxury vehicle manufacturer based on allegations that defective heating and air conditioning systems in a wide range of Mercedes-Benz vehicles accumulate mold and mildew that gets pushed through the vehicle cabins when the HVAC systems are operating, rendering the vehicles unusable for their intended purpose.

    December 2018: New Lawsuit Filed December 2018 in Federal Court on Behalf of Mercedes-Benz Owners Nationwide

    On December 12, 2018, Lieff Cabraser and co-counsel filed a larger, federal consumer fraud class action lawsuit against Mercedes-Benz USA and Daimler AG over owner allegations of defective air conditioning systems. Filed in the United States District Court for the District of New Jersey, the lawsuit claims the vehicles in question have a faulty design that, during normal and expected conditions, fails to properly evaporate or drain the accumulated system condensation, creating a rich environment for the growth of bacteria, fungi, mold, and spores, which then are blown into the passenger cabin when the AC System is in use.

    March 2018: Georgia Federal Court Decision Rejects Mercedes’s Attempt to Dismiss Plaintiffs’ Claims in Moldy AC Lawsuit

    In March of 2018, U.S. District Court Judge Amy Totenberg of the Northern District of Georgia issued an order denying most of Mercedes’s arguments attempting to dismiss Plaintiffs’ putative class action against Mercedes over allegations of mold in Mercedes vehicle AC. At the same time, the Court confirmed the validity of plaintiffs’ claims that Mercedes-Benz misled its customers by selling them expensive cars Mercedes knew to have defective, mold-harboring climate control systems. Per the Court’s order, the case will now move into the discovery phase. In particular, the Court has asked the parties to consider how discovery already taken in the related California case (discussed below) can be applied in this case to save time and cost, and increase efficiency in the discovery process.
