Complaint Summary
POWER TRAIN
Owner Narrative
Transmission. My 2021 Toyota Highlander with approximately 94,500 miles developed a consistent whining noise during acceleration. The issue occurs daily during normal driving and appears to be worsening. A Toyota dealership diagnosed the problem and confirmed the noise is coming from the transmission and that the transmission requires replacement. This appears to be a premature failure of a major drivetrain component. The condition could lead to loss of power or transmission failure while driving, creating a potential safety risk. There was no prior warning, and the vehicle has been properly maintained.
