Question juridique clé
Whether the cantonal cassation court acted arbitrarily in annulling the first-instance judgment and rejecting the claim for warranty reimbursement.
Solution extraite
No. The Federal Court found the cantonal court's assessment sustainable and not arbitrary.
Motifs extraits
The appellate court could exclude an initial defect because the buyer did not prove that the timing belt was excessively worn or that the vehicle's value or usability was reduced at sale; a manufacturer recommendation to replace the belt at 60,000 km did not itself prove a legal defect.
