Earlier this year I noticed cracks showing up around my ignition, those cracks have spread up to the top of the dash on the drivers side. Now, there are cracks on the passenger side leading up to and around the airbag. Just this week, I noticed the dash is starting to get tacky and dust is starting to stick to it. I am beginning to be concerned. About the safety as it appears the dash is deteriorating more and more as the days go by and am concerned for anyone riding with me. I understand Lexus has been aware of this problem for quite sometime but have failed to correct the defective dashes.

The dashboard on my 2006 Lexus RX330 has deteriorated over time. There are cracks in the dash, and soft spots that reflect sunlight as glare to the occupants of the car. My Lexus dealership (Lexus of tampa bay, fl) has so far been unable to help me with the dashboard defect. They told me Toyota corporate won't acknowledge the defect, nor provide any relief, especially since my car is out of warranty. I should note my car is kept in a garage, and the dashboard is only exposed to the Florida sun when I am driving (with the air conditioning on).

Multiple cracks and melting dashboard. The dash is very sticky and is falling off in pieces. I'm concerned if the airbags ever deploy this defective dash will become an ied!

The vehicle developed cracks in the passenger side of the dashboard. We were told this could be a safety risk related to function of the airbag. Lexus offered to provide a new dashboard if we paid the labor charge of $800. Eventually the dealer split the labor charge with us and we replaced the dashboard.

The car is a hybrid. It would not start (the ready light would not come on), therefore it was inoperable. Fortunately, the car was parked and did not die while driving. If it would have died while driving, many dangerous possibilities could have incurred. After having it towed to a Lexus dealer in columbus, the source of the problem was diagnosed as water in the hybrid battery area. After lengthy discussion with Lexus service personnel, they concluded that "welds" near the hatch hinges had come apart, which allowed water to seep into the interior of the car to the hybrid electronic controls. Lexus service had experience these problems before, and had guessed at a variety of reasons (such as excessive opening and closing of the hatch, wind catching the hatch while it was open, and other lame reasons). There is no ticker on the hatch to count how many times it was opened nor what there any gust of wind that would have cause the welds, two welds, to break allowing water to seep into the car. My conclusion is that since the problem has occurred before, that there is either a manufacturing issue, an engineering issue, or both. I am neither an expert in these areas, but do have some common sense. Lexus corporate or the dealer would not confess to the wrongdoing and therefore I had to shell out over $1600 in repairs. They wanted another $1100 to re-weld the 3 inch gap on both sides with painting included. Due to the expense, I had to opt for using silicone to seal the gaps and am forced to drive the car in dry weather.

The black plastic finish trim on the driver side rear triangular window blew off on the freeway at 65 miles per hour. Apparently this is a very common occurrence, since now that I am aware of it...I have noticed that other Lexus SUV's of the same or similar models have that piece missing! I saw 3 others just yesterday! I am thinking that whatever is suppose to hold that piece on is not sufficient to do so!

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?

As IżM sure you are aware ż 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.

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.
