Toyota is recalling about 645,000 vehicles worldwide to repair airbags that can fail to deploy in a crash, with about 49,000 of those cars in the U.S.
The automaker says the 49,000 include the 2016 Prius, 2016 Lexus RX and 2015-2016 Lexus NX. Recalled outside the U.S. are the Toyota Alphard, Corolla, Esquire, Highlander, Hilux, Levin, Noah, Probox, Sienta, Succeed, Vellfire and Voxy.
The National Highway Traffic Safety Administration hasn't released details about the recall, but Toyota says all the recalled vehicles were built between May 2015 and March 2016.
The automaker says open circuits could be created over time in the airbag systems and cause warning lights to illuminate and failures of the front, side and curtain airbags to deploy in a crash.
Toyota didn't release information about what's causing the open circuits or how the problem was discovered.
Toyota and Lexus dealers will inspect the serial numbers of the sensors and replace them if necessary when the recall begins in March 2018.
Affected owners may call Toyota at 800-331-4331 or Lexus at 800-255-3987.
