Federal regulations require dealerships to disclose known defects in used vehicles before the sale, and dealerships must ensure the vehicles are safe and meet safety standards. It is always a good practice to research and verify the vehicle history, ask for maintenance records, and have a pre-purchase inspection conducted by a trusted mechanic before purchasing a used vehicle.
As information can quickly change after my knowledge cutoff, it's always best to consult the latest official sources, such as the National Highway Traffic Safety Administration (NHTSA) website or the Toyota website, for the most up-to-date information on recalls, safety issues, and any ongoing concerns.
