Case Facts & Court Holding
Key Facts & Case Background
Magdalene Smoot was injured when the airbags in her one-year-old Mazda deployed after she struck a pothole or a piece of asphalt while driving 35-40 mph. The day prior, she had received a recall notice from Mazda warning of an “increased risk of airbag deployment in a low speed crash or minor impact to the undercarriage.” The Smoots sued Mazda for products liability, intending to rely on the doctrine of res ipsa loquitur to establish a defect without presenting expert testimony. The car was repaired and sold before the lawsuit, preventing inspection of the airbag control unit. After the district court ruled that res ipsa was inapplicable, the plaintiffs retained an expert, but the court excluded his testimony as unreliable under Fed. R. Evid. 702. The district court then granted summary judgment for Mazda, and the plaintiffs appealed.
