JIM WANG; DEAN WANG; YU BAI v. MASERATI NORTH AMERICA, INC.; JOHN DOES 1-10
The Third Circuit affirmed summary judgment for Maserati because the plaintiffs failed to provide expert testimony proving a vehicle defect caused a garage fire. The court clarified that while expert testimony is not always required for complex instruments, it is necessary when the average juror cannot deduce the cause of failure without technical knowledge.
