101 F.4th 983
8th Cir.2024Background
- Molitor Equipment, LLC purchased two 2018.5 model year John Deere RX tractors from Deere & Company, which did not include engine side shields as standard, unlike later 2019 models.
- Fires destroyed both tractors a year after purchase, while still under Deere’s express manufacturer’s warranty against defects in materials or workmanship.
- Molitor’s insurer, Secura Insurance Company, paid the loss and subrogated to pursue warranty claims against Deere, alleging the absence of side shields was a defect.
- Secura sued Deere for breach of warranty, claiming both a design and manufacturing defect; Deere moved to dismiss design defect allegations, contending their warranty covered only manufacturing defects.
- The district court dismissed the design defect claim and later granted summary judgment to Deere on the manufacturing defect claim, finding the tractors matched Deere’s intended design.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Does warranty for "material/workmanship" cover design defects? | The “material/workmanship” warranty covers design defects; meaning is unclear without discovery. | Warranty covers only manufacturing (not design) defects; unambiguous. | No—warranty is unambiguous and excludes design defects. |
| Is failing to include side shields a manufacturing defect? | Absence of shields was a defect, thus breach of warranty. | Tractors built as designed; absence was intentional, not a manufacturing error. | No—tractors conformed to design, not a manufacturing defect. |
| Can extrinsic evidence show warranty ambiguity? | Extrinsic evidence needed to interpret warranty scope. | Warranty is unambiguous; extrinsic evidence is inadmissible. | No—extrinsic evidence barred due to lack of ambiguity. |
| Is an implied warranty of non-defectiveness preserved by disclaimer? | Deere could not disclaim a supposed implied warranty of non-defectiveness. | Minnesota law allows disclaimer of implied warranties. | Disclaimer is valid under Minnesota law. |
