general problems of the 2006 Lexus Rx400h

2006 Lexus Rx400h (and other Toyota/Lexus models). Anti bacterial / mold coating on a/c evaporator begins shedding with age/time and blows white powder/dust through vehicle. Lexus says it's aluminum hydroxide, and it's perfectly safe. How can it be safe to inhale / ingest a foreign substance? has Lexus / Toyota done any studies regarding aluminum hydroxide. If it's safe, why does Lexus / Toyota now offer (and install in new vehicles) an a/c evaporator without the coating?.

While driving my 2006 Rx400h, I slammed on the brakes and my heel went through two carpets and the floor board. My heel was stuck in a hole in the floor board. I can now place my finger into a hole and feel wires and empty space under the gas and break path. Lexus has agreed to fix the problem for a fee. (50%) the sales manager informed me that the design of the front floor board has ripples. (like peaks and valleys). There are two holes lined up directly under each pedal. The consequence: heels and ripples under a floor board don't mix. . . . Thank you for your time.

As im sure you are aware hybrid cars are very quiet and thus present a danger to people walking through parking lots. The danger is particularly serious when those driving the hybrids are backing out of parking spaces - no matter how carefully the drivers are backing out! pedestrians depend on their hearing to alert them to cars backing out, so they simply walk right behind a car that is already moving. I own a 2006 Lexus 400h and I have been trying to purchase replacement back-up lights that beep to alert pedestrians, but none are available from any source. I urge the national highway traffic safety administration to take quick action to ensure that future models include external sound for hybrids when they are backing up and also to make it possible to purchase replacement back up lights that provide that same capacity for older hybrid models.
