310 F. Supp. 3d 699
United States District Court2018Background
- Plaintiffs (19 named, from 17 states) allege design defect in Ford’s Gen II electronic throttle control (ETC) with three-track pedal sensors caused unintended accelerations (UAs) in vehicles purchased/leased 2002–2010; claims include breach of warranty and unjust enrichment.
- Plaintiffs contend the ETC is not fault-tolerant and should have included a failsafe (e.g., Brake Over Accelerator/Brake Override) to stop or mitigate UAs.
- Many named plaintiffs alleged UAs, but only two originally had experienced a UA at early stages; most do not claim personal injury — damages are economic (overpayment/diminished value).
- Plaintiffs’ design experts identified hypothetical failure mechanisms (sensor wear/contamination, wiring chafe, corrosion, EMI, etc.) but none inspected or tested the plaintiffs’ individual vehicles or linked those mechanisms to specific UA events.
- Ford’s expert inspected and tested ten available plaintiff vehicles and found no abnormal ETC conditions or sensor/electrical faults that would cause throttle control failures; Ford moved for summary judgment on warranty and unjust enrichment claims.
- Court required proof of causation: a manifestation of the alleged defect (a UA) must be shown to be caused by the ETC defect; plaintiffs failed to produce competent expert testimony or objective vehicle-specific proof tying their UAs to the alleged defect.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether plaintiffs may pursue breach of warranty/unjust enrichment absent a defect manifestation in their own vehicles | Plaintiffs: defective design itself is a manifestation; overpayment/diminished value is actionable even without a realized UA | Ford: no injury where vehicle performed satisfactorily; must show actual manifestation (UA) caused by defect | Court: Plaintiffs without a UA (or without proof defect caused UA) cannot maintain warranty or unjust enrichment claims; prior rulings upheld this rule |
| Whether plaintiffs produced competent evidence tying alleged UAs to ETC defect | Plaintiffs: experts identify plausible ETC vulnerabilities and opine consistency with reported UAs | Ford: experts did vehicle-specific inspections showing no ETC faults; plaintiffs’ experts did not inspect plaintiffs’ vehicles or offer vehicle-specific causation opinions | Court: Plaintiffs’ experts failed to provide vehicle-specific causal proof; summary judgment for Ford on these claims |
| Sufficiency of expert testimony at summary judgment | Plaintiffs: general/design-level expert opinions are sufficient to raise triable issue | Ford: general hypotheses without inspection/testing of subject vehicles are insufficient under summary judgment/Celotex standards | Court: General hypotheses insufficient; need competent expert testimony and objective proof linking defect to each UA |
| Burden at class certification/individual causation pre-class | Plaintiffs: class claims focus on common defect; individual manifestations not required pre-certification | Ford: before class, individual plaintiffs must show causation for their own claims at summary judgment | Court: On summary judgment, focus is individual plaintiffs’ evidence; lack of causal proof defeats warranty/unjust enrichment claims |
