Takata recall - immediately after purchasing this used car, I noticed the red light, but was not aware at the time that it was warning light. So my airbag red light remains on all the time once the car Is started. I later was informed that this should not be happening and I am now fearful and see this as an airbag defect that could lead to serious concern of questionable safety. I think it Is unfair that Lexus now wants to charge me $280 for a diagnostic for the root of this problem, when in fact they know that these takata airbags are not safe and millions of cars have already been recalled.
