Toyota has issued a global recall for defective airbags of 645,000 of which 49,000 are in North America, and including the 2016 Prius.

Specifically, the issue is caused by an open electrical circuit due to weak, peel-prone insulation layers. This may cause the vehicle’s airbag warning lights to turn on and its front curtain shield and/or side airbag not to deploy in the event of a crash.

The recall covers all Toyota Prii made between May 2015 and March 2016. All bad airbag sensors will be replaced at no charge by dealers after a check of airbag sensor serial numbers to determine if it is affected.

Other vehicles affected include model year 2016 Lexus RX and model year 2015 and 2016 Lexus NX crossovers, along with some global models including Toyota Alphard, Vellfire, Sienta, Noah, Voxy, Esquire, Probox, Succeed, Corolla, Highlander, Levin and Hilu. This issue is not related to the Takata airbag recall which has affected more than 37 million vehicles across 19 automakers to date.

Affected owners can visit the Toyota Recall page and enter their 17-digit VIN (vehicle identification number) to check current information, as well as the NHTSA recall page for the latest updates. Toyota has also provided a customer support number – 1.800.331.4331. Owners will also receive a snail mail notification as early as late March 2018.
