Front Driver Side Air Bag Inflator problems of the 2006 Lexus IS250

I received a Lexus safety recall notice on 7/18/16 regarding the takata front passenger airbag inflator (NHTSA recall no. 16v-340). The propellant in these inflators may degrade after prolonged exposure to high absolute humidity and fluctuating high temperatures. Degraded propellant can cause inflator rupture during airbag deployment. In the event of an inflator rupture, metal fragments could pass through the airbag cushion material, striking the vehicle occupants and result in serious injury or death. My car is used to transport my family, which includes my 6 month old son. We do not feel safe driving my car and would like to receive a loaner until the airbag parts have been replaced. Also, we live in an area where temperatures reach up to 100 degrees in the summer months, which may increase the risk of the propellant in these inflators to degrade.

Takata recall - airbag light has been on. They replaced recalled inflator. Light is still on. Dealer now says it's a wiring harness. About $2500 to replace. After researching on internet, many people are having same problem. A technical service bulletin ya been issued to the dealers and covered by warranty to 72 months or 70,000 miles. My car has 88,200 miles. Most people that solved the problem in their own have said this is connection issue from the harness connectors to the igniters. They are vibrating loose. I am disappointed Lexus doesn't offer more support on this issue as it's severely hazardous for many in this situation. If it's a connection issue, it's ridiculous dealers are charging thousands of dollars to fix an entire harness. Can anything be done?.
