The issues with my car: the rear door wouldn't open with the remote, the roof rack wouldn't move back and forth, the leather under the head rest was torn, the wiper mist was not working. They don't charge me for fixing these issues. But my understanding is that some of these issues are not supposed to be issues because they are supposed to get inspected before they certify it. So I guess you can not really believe the Lexus certification process. Also the rear door issue seems to be a recurring issue. It still wouldn't open some times after 3 attempts to fix this.
Do not grey out the navigation when the vehicle moves.
