TOYOTA issued a recall on the RX 350, and RX 450H models

On certain vehicles, the driver’s knee airbag inflator may have been assembled with an improperly located weld seam. If this condition is present, the weld could be insufficient or be damaged during the clinching process after the inflator was filled with gas, which could cause the stored gas to leak. Leakage of the stored gas could affect the performance of the knee airbag. Failure of the airbag to fully deploy during a crash (where deployment is warranted) could increase the risk of personal injury to the seat occupant. Correction: Dealers will inspect and, if necessary, replace the knee airbag assembly.
