The 2013 Toyota Highlander has 3 recalls, the most serious being a second-row left seat that can fail to lock into its track in certain forward positions, leaving the seat free to shift in a crash and raising the risk of injury to that occupant.
A related recall covers the same left second-row seat track and its ability to meet required strength standards when positioned in those same forward adjustment slots. Prior repair attempts may not have fully resolved this issue across all jurisdictions, but the physical concern is the same: the seat may not stay anchored under crash forces. There is also a separate concern involving the front passenger seat's occupant sensing system, which detects whether the seat is occupied and adjusts airbag deployment accordingly. If that sensor falls out of calibration, the front passenger airbag may either fail to deploy in a crash or deploy with too much or too little force for the person sitting there, neither of which provides the protection the system is designed to deliver.
