We received a safety recall letter 0n July 2016 . It says that continued exposure to high levels of absolute humidity may cause the passenger frontal air bag inflator housing to rupture and deploy abnormally in the event of a crash necessitating deployment of the frontal air bag . Metal fragments may strike the occupants the vehicle. . We call several dealers to fix the bproblem , but they said that the parts were not ready and they were going to call us back. . Somebody told us that theay were going to give us a rental car while this problem was fixed. Then on October /2016 we received another safety recall letter saying that it is possible that water may enter the front suspension lower arm ball joint fitting during driving. We have called the dealers and they said that the don't have the parts ready. This is our main family vehicle and we don't have any other means of transportation.
