181 F. Supp. 3d 988
S.D. Fla.2016Background
- This is an omnibus Daubert/Rule 702 order on Ford Motor Company’s motions to exclude three of plaintiff Angela Sanchez-Knütson’s experts (Renfroe, Penney, Gaskin) in a putative class action about alleged carbon monoxide (CO) infiltration into 2011–2015 Ford Explorers.
- The court reviewed briefing, exhibits, and argument and applied the Rule 702/Daubert gatekeeping framework (qualification, methodology reliability, helpfulness).
- Renfroe (mechanical engineer) performed vehicle tests on Explorers measuring air/gas leakage, pressure differentials, and CO accumulation; Ford attacked sample/class and test methods. Court found such criticisms go to weight, not admissibility, but limited Renfroe from opining on diminution in value, toxicology, and HVAC replacement costs.
- Penney (CO researcher) proposed that WHO and EPA CO standards should govern acceptable in-vehicle exposure; Ford argued he advocated a zero-exposure standard and lacked testing. Court held Penney did not advocate zero exposure and his opinions on acceptable CO levels are admissible (he need not test vehicles to opine on standards).
- Gaskin (market research/conjoint analysis expert) produced a conjoint survey estimating diminished vehicle value (expressed as a percentage). Ford attacked sampling frame, variable design, lack of econometric regression, and speculative damages under FDUTPA. Court allowed Gaskin’s testimony, finding methodological attacks go to weight and that conjoint analysis can be a permissible FDUTPA damages approach.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of Renfroe’s testing and opinions | Renfroe is qualified; tests show CO/infiltration under certain conditions and are relevant | Tests are unreliable, unrepeatable, poor sample/class, and some opinions exceed his expertise | Admitted except excluded opinions on diminution in value, toxicology, and HVAC replacement costs; methodological criticisms go to weight |
| Admissibility of Penney’s CO-health opinions | Penney is a qualified CO researcher; WHO/EPA standards should apply to in-vehicle exposures | Penney allegedly advocates a zero-exposure standard, is speculative, and performed no vehicle testing | Admitted; Penney did not advocate zero exposure and need not conduct vehicle testing to opine on acceptable CO limits |
| Admissibility of Gaskin’s conjoint damages model | Conjoint survey valid to estimate percent diminution; results can be applied to class via pricing evidence | Sample/national frame, variable design, combining lessors/purchasers, lack of hedonic regression, speculative FDUTPA damages | Admitted; methodology challenges go to weight; conjoint analysis permissible for FDUTPA diminished-value damages |
| Use of damages percentage vs. actual dollar amounts | Gaskin provides percentage diminution; plaintiff will apply to class pricing data at trial | Ford: arbitrary $45,000 baseline and speculative without market regression or seller behavior | Court allows percentage-based conjoint results; Ford may present contrary market evidence at trial |
