The check engine light and p0aa6 warning illuminated and vehicle went completely dead, could not start up. There were cracked body seams above the rear door strut mounts allowing water intrusion to flood the entire bottom well under the floor boards which shorted out the entire hybrid battery system. There were no visible signs of water intrusion inside the cabin of the vehicle, nothing was wet. Apparently, lexus has two tsb's on this issue, l-sb-0019-09 & l-sb-0045-09, on how to repair the seams since over time there appears to be a structural flaw allowing the seams to separate. The water intrusion happens silently and without warning and presents a severe safety hazard as you get water into an electrical system and parts begin shorting out without advanced warning. Imagine traveling at a high speed and the hybrid battery shorts and the vehicle abruptly stops! Or an electrical short starts a fire! Lexus is aware of the potential problem and how costly the damage is and the safety risks associated as a result and has chosen not to issue a recall or limited campaign to allow for a simple repair of the seams to prevent major damage from occurring.
2006 Lexus RX Hybrid body complaints

As I was pulling into a parking space on the 4th level of a 6 story parking building, I had my foot on the brake pedal and the vehicle was coming to a stop, suddenly the vehicle accelerated (lounged) forward. There were steel cables (rail guards) that stopped the vehicle from going over and nose diving onto the street below. The front bumper and the hood were damaged. I took the vehicle to the local lexus dealer and had them check the braking system for any defects. After doing a "health check" on the vehicle the lexus rep told me that there was nothing wrong with the braking system. I also filled a report with lexus customer service and they told me, a technical inspector will go to the dealership and check the vehicle out.
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?
My uncle bumped his leg on the door edge of his 2006 lexus400h, cutting his leg which required 5 stitches. The exterior panel is much bigger that the interior panel which leaves a huge pointed section that sticks out rather than tapering safely in: if you look straight down on it you can see how it sticks out.
As I'm 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 federal safety agency 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.

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.
