NHTSA Complaint #11717006 — 2021 TOYOTA HIGHLANDER

•The transmission malfunctioned and developed an abnormal internal noise at approximately 67,000 miles, which is an unexpected failure at low mileage. The vehicle had been properly maintained and had no prior mechanical issues. Atlanta Toyota inspected the vehicle and confirmed the transmission had failed and required full replacement. The dealer also stated that as a result of the transmission failure, other related components showed excessive and abnormal wear. A second independent service center inspected the vehicle and confirmed the same diagnosis. The vehicle is available for inspection upon request. • This unexpected transmission failure created a serious safety risk due to the possibility of sudden loss of power, inability to accelerate, or complete transmission failure while driving. I rely on this vehicle daily to transport my child to school and to commute to work. A sudden failure while in traffic could result in becoming stranded or involved in a collision. • The vehicle was inspected by an authorized Toyota dealer and an independent service center. Both stated that the failure was unusual given the low mileage and normal use of the vehicle. • There were no warning lights, messages, or diagnostic trouble codes prior to the failure and afterward. The only symptom was an abnormal internal noise from the transmission, which began suddenly at approximately 66,000 miles. • The vehicle has received regular maintenance and is used for normal daily driving. There was no abuse, heavy towing, or unusual use that would explain a transmission failure at this mileage.
