O'Connor v. Ford Motor Co.

Summary

The United States District Court for the Northern District of Illinois addresses competing Daubert motions concerning warranty experts Nathan Soderborg and Frank Bernatowicz in a putative class action alleging defective 10-speed transmissions in 2017–2020 Ford F-150 trucks. The court evaluates the relevance, reliability, and qualifications underlying the experts’ warranty-data opinions in advance of class-certification proceedings.

Holdings

1. Soderborg’s opinion that harsh-shift warranty claim rates varied substantially by engine type, drivetrain, and body/cab style was relevant and sufficiently reliable, and Soderborg was qualified to offer the statistical warranty analysis and related inferences. The motion to exclude Opinion No. 1 was denied.
2. Soderborg’s comparison of early warranty-claim rates for the 6R80 and 10R80 transmissions was admissible. Plaintiffs’ challenges to missing data, excluded vehicles, and the selection of the 6R80 as a benchmark concerned the weight of the opinion rather than its admissibility.
3. Bernatowicz was qualified to offer opinions responding to Soderborg’s analysis of Ford’s warranty-claims data.
4. Bernatowicz was barred from testifying that Soderborg’s use of estimated future rates or the Kaplan-Meier model was unreliable because that critique rested on a mistaken understanding of Soderborg’s analysis. He was also barred from offering additional undisclosed critiques of the model developed only at deposition.
5. Bernatowicz’s opinion that the 6R80 was an unreasonable benchmark because it had allegedly been subject to recalls and unacceptable performance was excluded as inadmissible ipse dixit.
6. Bernatowicz’s opinion that Soderborg’s dataset was incomplete because of omitted customer-care codes, potentially underreported claims, and excluded sources of customer contact was admissible rebuttal testimony.
7. Bernatowicz’s comparative analyses of warranty claims and NHTSA complaints were admissible. Ford’s criticisms of the data and competing conclusions went to weight rather than admissibility.
8. Soderborg’s rebuttal Opinion No. 11, asserting that the warranty claim set was inconsistent with a single uniform defect, was improper rebuttal testimony and was excluded.

Questions Presented

1. Whether Soderborg’s opinions concerning variations in warranty claim rates across vehicle characteristics and comparisons between the 6R80 and 10R80 transmissions were admissible under Rule 702 and Daubert.
2. Whether Bernatowicz was qualified to offer opinions concerning Ford’s warranty claim data.
3. Whether Bernatowicz’s critiques of the Kaplan-Meier model, the 6R80 benchmark, alleged underreporting, and comparative warranty and NHTSA data were admissible.
4. Whether Soderborg’s rebuttal Opinion No. 11, asserting that the warranty claims did not reflect a single uniform defect, was proper rebuttal testimony under Rule 26.
