•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.
3 wheel alignments in same vehicle needed in less than 30 months: <5,000, 30,000 and 35,000 odometer readings it’s not from pot holes; I have owned about 14 cars in family fleet and have never had 1 vehicle need more than 1 alignment during it’s time of ownership of over 1,000,000 miles driven something is wrong with vehicle design or mechanical components to go out of alignment so frequently.
I was forced to change lanes quickly from the left lane to the left shoulder of an interstate when a double tandem tractor trailer moved into my lane of traffic. The interstate was dry and the left shoulder was in excellent condition and wide enough to accommodate my vehicle easily. All lane assist options were turned off, the driving mode was set to “economy” and the cruise control was turned to “off”. A few seconds after entering the left shoulder of the interstate, I felt the rear end of my vehicle sway from side to side for a few seconds. After the swaying ended, I thought there was a brief loss of vehicle control after which the vehicle returned completely to my control. My vehicle is a Toyota Highlander limited awd gas engine SUV with about 2700 miles when this occurred. I drove my vehicle without any emergency steering maneuvers 2700 miles prior to and 500 miles after this incident without any problems. I had my Toyota dealer examine the suspension, steering and event recorder of the vehicle and test drive it. They found the vehicle to be performing within manufacturers specifications and without any defect in the steering or suspension and found no codes found in the event recorder.
