98 F. Supp. 3d 919
N.D. Ohio2014Background
- Plaintiffs move to exclude three defense experts (Paul M. Taylor, Ph.D., P.E.; Christine T. Wood, Ph.D.) and defendant moves to strike plaintiffs’ expert (R. Scott King) under Fed. R. Evid. 702, 703, 401, and Daubert/Kumho standards.
- Dispute centers on whether experts’ opinions (vehicle maintenance/repair cost analysis, human-factors materiality opinions, and spark-plug defect/repair-cost opinions) are qualified, reliable, and relevant to consumers’ disclosure/materiality and defect issues.
- Taylor offered opinions comparing overall maintenance/repair costs of subject vehicles to comparators using third‑party data and his 25+ years of automotive engineering experience. Plaintiffs argued his opinions lack reliable methodology and omit spark‑plug cost specificity.
- Wood, a human‑factors expert, opined that spark‑plug information would not be material to reasonable buyers (first three opinions disputed); plaintiffs challenged her qualifications for some opinions and the scientific basis for her materiality conclusion.
- King, plaintiffs’ mechanical expert, opined spark‑plug breakage is abnormal, caused by a defect, increases owners’ costs, and that Ford had prior knowledge; defendant challenged relevance, foundation, and a specific $105 labor figure.
- The court conducted a Daubert/Kumho gatekeeper review and denied all three motions to exclude, finding the experts presently meet Rule 702’s qualification, relevance, and reliability thresholds.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of Paul M. Taylor (cost/repair opinions) | Taylor’s cost opinions are unreliable, lack scientific method, rely on unexamined third‑party data, omit spark‑plug replacement costs | Taylor is experienced, relied on industry data and recognized sources; opinions help compare overall maintenance costs | Denied — Taylor qualifies and his opinions meet Rule 702 at this stage |
| Admissibility of Christine T. Wood (human‑factors/materiality) | Wood is not qualified for specific materiality conclusions and lacks valid scientific basis, especially for opinion that disclosure would not affect buyers | Ford asserts Wood is qualified and her first three opinions are supported; Ford does not rely on her fourth opinion | Denied — Wood is qualified and her first three opinions have a sufficient evidentiary/scientific basis now |
| Admissibility of R. Scott King (plaintiffs’ mechanic/defect opinions) | (Defendant) King largely parrots documents/testimony, offers irrelevant ‘‘consistent with defect’’ opinions, lacks support for $105 labor estimate | King is qualified by experience; his opinions assist jury on consumer expectations and are relevant under low Rule 401 bar | Denied — King is qualified and his declaration is sufficiently relevant and admissible now |
