Summary: Combustion Engineering Expert Witness testimony allowed even though the defendants argued that his opinions were unreliable based on his reliance of conclusions of one problem vehicle.
Facts: This case (Counts, et al. v. General Motors, LLC – United States District Court – Eastern District of Michigan – June 9th, 2022) involves a claim by consumers who purchased a 2014 or 2015 Chevrolet Cruze diesel from the defendant. The plaintiffs allege that they overpaid for their vehicles because they were tricked into purchasing a Cruze with “defeat devices” that made its emissions comply with numerous state and federal regulations. The plaintiffs claim that their Cruze vehicles emit dangerous amounts of oxides of nitrogen, which exceed state and federal emission standards. The plaintiffs hired Combustion Engineering Expert Witness Juston Smithers to provide expert witness testimony in this case. General Motors has filed a motion to exclude this expert from testifying.
