NHTSA Complaint #11708000 — 2020 TOYOTA HIGHLANDER

The contact's wife owns a 2020 Toyota Highlander. The contact stated that soon after purchasing a new set of tires, the vehicle made an abnormal rattling sound upon acceleration. The vehicle was taken to a dealer for an oil change and tire rotation, and the contact was informed that no defect was found on the vehicle. As the failure persisted, the vehicle was taken back to the shop, where the tires were purchased. The contact was informed that there was no defect in the tires, and the failure might be related to the differentials of the vehicle. The vehicle was taken back to the dealer, where it was diagnosed with transmission failure. The manufacturer was then notified of the failure, and the contact was offered partial financial assistance towards the purchase of a new engine. The vehicle was not repaired. The failure mileage was approximately 55,000.
