The rubber cover for the rear hatch is "melting" very sticky and will not open the door.

Brakes did not apply as expected, experiencing a significant "push" while braking at low speed. It was so obvious that I had to step on the break pedal to keep the car from running out into the car in front. This one time I crashed into front car. I took it to dealer to check the brakes, and he is saying they are hybrid and thats how they work. This is not acceptable as the brakes are meant to stop the vehicle with immediate effect. This is not happening with my RX 400h, I bought this car in Sep 2014 and within 2 months I met with accident. I never had history of accident with other cars.

Car was being pulled into space in restaurant parking lot -- space was on grass up a slight incline (approximately 12 inches) -- as car was moving up the incline a small bump was felt under the car and the car suddenly accelerated and continued to accelerate -- brakes were applied immediately but were unable to stop the car -- the car swerved and hit a tree approximately 20 feet from the parking spot -- believe the "bump" felt under the car caused the sudden acceleration -- above account can be verified by the other person in the car who had the same description of events.

Having enjoyed owning a Lexus rx300, I made a huge "investment" and purchased the 2006 Rx400h. In April of 2014, the vehicle would not start due to a failure of the hybrid system. I attempted to jump start the vehicle as suggested by the Lexus dealer. Upon further investigation I discovered the carpet inside the cabin area was soaking wet! the car had been outside in the rain with the windows, sunroof and doors closed. Also, I take the car to an automatic car wash on a regular basis. While loading the car on to the jerr-dan tow truck, a large amount of water poured out of the rear trunk area. The tow truck operator was amazed at the amount of water that was pouring onto the driveway. The vehicle was taken to the Lexus dealer. After several days, a leak in the rear hatch area was found to be the source of the water. There apparently is a metal seam where the welds do not hold up or were not welded properly. Water collected in the hybrid battery area causing over $7000 damage. Of course, luckily for Lexus, the vehicle warranty had expired. The only recourse I had was to make a claim to my insurance, which only covered the damages but not the cause. My out of pocket expenses are approximately $3000. Water leaking from the outside into the cabin of a vehicle, especially one of this price, is unacceptable. And to have water collect into the "heart" of the vehicle and render the vehicle inoperable is frightening. I could have been on an isolated road or a busy highway and the vehicle could have suddenly quit. Lexus knew about this potential problem but did not advise their customers to watch for any signs of moisture. The repair to the popped seam could have been done by any body shop or, I'm told, the use of a good quality silicone. There is a technical service bulletin from 3/10/2009 that specifically addresses this problem: TSB-l-sb0019-09 rev 1.

While slowly pulling into a parking space in a parking structure, the car suddenly accelerated and crashed into the cement block wall in front of me. Since the distance from half-way into the parking space to the wall was small (probably three to four feet), I had no time to slam on the brakes before impact. The car was towed to a Lexus dealer. I was immediately referred to their legal department who handled all transactions after that. An independent evaluator inspected the car, retrieved the crash data retrieval recorder and issued a report. The cdr indicated that the accelerator and the brakes were not pushed until after the crash, and that the speed in the few seconds before the crash went from 3. 7 to 60. 9 mph. Lexus refused to admit there was a problem, stating only that the brakes, accelerator and floor mats seemed to be in good working order. I refused to drive the car again or have only the body fixed and sold to an unsuspecting third party. It was eventually declared a total loss by our insurance company. There was no help or admission of a problem from Lexus, except to try to charge us for car storage at the dealership during the process.

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.

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.

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 if you look straight down on it you can see how it sticks out.
