The top convertible motor got broken about two years after I bought it so I went back to the dealership and luckily it was under warranty so they replace it but now the one they put on that time now it's broken again and they want to charge me to get fixed.
Door locks not working properly. Both front door actuators need to be replaced which we were told is a very common problem with this model. This has been unsafe for our teenage driver having to crawl through back doors to unlock her vehicle especially at night.
Unintended acceleration while inching into parking space at very slow rate of speed. Engine raced unexpectedly and car jumped curb with all 4 tires, across a small median, and down another curb with 3 tires, striking a parked car, which stopped forward motion.
This is the third lexus I have had that the automatic door locks don't work. All 4 actuators are bad after I even had one replaced. I have had this happen I all three lexus' that I have owned. I have talked to lexus about this and the service people say that they see more than they should go. Bad boy. Lexus/toyota does not think it's a problem.

I would like to see either toyota or lexus step up and admit they have a problem and fix them.
