## Facts

- Heaton purchased a new Ford four-wheel-drive pickup for highway and off-road use and drove it about 7,000 miles without noticing abnormal performance.
- Heaton testified the truck was rarely driven off pavement and was not subjected to unusual stress before the accident.
- While driving at normal speed on a blacktop highway, the truck struck a rock about five to six inches in diameter.
- The truck continued operating for roughly 35 miles, then left the road and tipped over.
- After the accident, a wheel assembly showed separation of the rim from the spider (the inner portion bolted to the vehicle); the rivets connecting them appeared sheared, and the spider showed dragging marks.
- The wheel rim had a large dent, and the inner tube had a cut near the dent.
- Heaton sued Ford under strict products liability, alleging the wheel was dangerously defective when sold.
- The trial court granted Ford an involuntary nonsuit for insufficient proof; Heaton appealed.

## Issues

1. Whether the evidence, largely circumstantial and based on a wheel malfunction after striking a rock, was sufficient to allow a jury to find the wheel was dangerously defective when it left the manufacturer’s control.
2. Whether the asserted failure could support an inference that the product was unreasonably dangerous beyond ordinary consumer expectations, as required for strict liability under Restatement (Second) of Torts § 402A.

## Decision

- The Oregon Supreme Court affirmed the involuntary nonsuit for Ford.
- The court held the evidence did not reasonably support a finding that the wheel was in a dangerously defective condition at the time of sale.
- The court accepted that circumstantial evidence can, in principle, establish defect, but found the proof here too speculative because plausible alternative causes (including damage from the rock impact) were not sufficiently excluded.
- A dissent would have treated consumer expectations about a truck wheel’s ability to withstand an impact with a rock of this size as a jury question.

## Legal Principles

- Oregon applies strict products liability consistent with Restatement (Second) of Torts § 402A for products sold in a dangerously defective (unreasonably dangerous) condition.
- “Unreasonably dangerous” is evaluated by ordinary consumer expectations: whether the product is more dangerous than an ordinary purchaser would reasonably contemplate.
- A plaintiff may rely on circumstantial evidence of product failure to infer defect, but must present facts from which a jury can reasonably conclude the defect existed when the product left the defendant’s control rather than from ordinary accident causation or post-sale damage.
- Courts may remove a case from the jury via nonsuit when the plaintiff’s evidence cannot reasonably support the inference of an unreasonably dangerous defect.

## Conclusion

The court affirmed nonsuit because, although strict liability under § 402A permits proof by circumstantial evidence and uses a consumer-expectations standard, the record did not provide a sufficient basis for a reasonable jury to infer that a dangerously defective condition existed at the time of sale rather than that the wheel failed from impact-related damage.
