This car is experiencing symptoms exactly as described in the inverter module recall, whereby after highway driving, the electric motor will fail randomly, tripping all dashboard failure lights, and putting the vehicle in "limp" mode, where it either slows significantly or stops, and then thus poses great safety risk with surrounding traffic.

The rear switch on the tailgate is melted. When you push on the button if feels sticky and comes off on your hands. To replace this part it cost $100 for the part and $200 to install. When I looked online so many people are having this issue. Something is wrong with the making of this part. It has failed.

Rear latch melted, not due to temperatures in the city and state where I live but instead to a electrical component overheating. Lexus will not fix without a charge of over $200. This is clearly a defect

The rubber cover of the liftgate sensor melted. I am concerned about it catching fire. I have read multiple complaints online from owners with the same issue. The black rubber melts and sticks to fingers. I also causes the sensor to malfunction since the rubber piece interferes with the sensor.

I noticed my back door opener switch was starting to melt. At first we thought its from the heat of the summer but then after careful consideration we thought that we've had the car for 4 previous summers with no issues with said button. We thought that there must be some electrical component inside the automatic button that must be getting too hot that's causing the hard plastic to melt.

Just wish to report melted rear door latch... been getting gooey for months and finally came off - seems to be an ongoing problem with several Lexus and Toyota vehicles. Wasn't sure if this is heat related or electrical.

I was driving my 2008 Lexus RX350 on the freeway at 65mph and my son rolled down his window and instantaneously there was an extreme and painfull cabin pressure that Lexus call "normal cabin pressure". it startled me, I almost crashed with my wife and two kids in the car with me.it makes your ears hut, very painfull. I bought a Lexus because of T he quality and luxury that the Lexus corporation portays. I am vey disappointed because the Lexus dealership told me this is normal cabin pressure. The corporate office told me that this is normal and is no longer wanting to discuss this matter any further with me. They said that I will have to hire a lawyer if I want to pursue this matter any further. I think that the Lexus corporation is promoting false advertisement by claiming that they are commited to high quality and luxury while still mass producing the Lexus rx model with this deffect of "normal cabin pressure". this is so frustrating. I finally buy a luxury vehicle and it turns out to be defective with no apparent solution. Bassically I just have to live with this ear pearcing annoyance. What a disappointment with Lexus.I payed so much money for a disappointment!
