The recall affects approximately 482,000 vehicles in the U.S. and includes the 2010-2012 Prius, 2010-2012 Prius Plug-In Hybrids and 2011-2012 Lexus CT200h. According to Toyota, the involved vehicles are equipped with curtain shield airbags (CSA) in the driver and passenger side roof rails. Those airbags feature inflators composed of two chambers welded together and some inflators could have a small crack in the weld area joining the chambers. As a result, the crack could grow over time and lead to the separation of the inflator chambers.

If an inflator separates, the CSA could partially inflate and in limited circumstances, one or both sections of the inflator could enter the interior of the vehicle. This increases the risk of injury if an occupant is inside the vehicle when this occurs.
To resolve the issue, Toyota and Lexus dealers will install retention brackets on the curtain shield air bag inflators at no cost. The retention brackets are designed to prevent the inflator chambers from entering the vehicle interior if separation occurs.
