“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.”
NHTSA complaint #10664822, filed 2014-12, 104,000 miles“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.”

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. …”
NHTSA complaint #10483763, filed 2012-11, 40,000 miles“The rear switch on the tailgate is melted. When you push on the button if feels sticky and comes off on your hands.
