The National Highway Traffic Safety Administration (NHTSA) announced today that Toyota will voluntarily recall 550,007 examples of the 2021–2024 Highlander SUV, including its hybrid sibling, to fix a potentially dangerous flaw with the second-row seatback locking mechanism. Discovered during a routine inspection at the factory that builds Highlanders, the issue pertains to a backrest that may not lock in place after using the reclining feature, which could result in injuries in a crash.
