Two problems related to wiper have been reported for the 2021 Lexus RX. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2021 Lexus RX based on all problems reported for the 2021 RX.
Front wiper motor damaged two times in fourth years. First time on 2023 and was replaced by warranty at the Lexus dealer and the second time was damaged on August 22, 2025. Now it is damaged but not covered by warranty at this time with 52,000 miles on the car. The wiper motor was damaged and it can not move down to hide inside down the hood, when the front wipers on they moved and the wiper hits the hood and peel the hood's paint.
On my 2021 Lexus Rx350l, the left-hand side outer rear-view mirror vibrates. This can be observed when the car is driven >35mph or when driving on rough roads. At freeway speeds, the mirror vibrates to such a degree that it is difficult to see from it and causes perception issues. I noticed this issue even more pronounced on some other 2021 Rx350 vehicles that I test drove before purchasing the one I own. The issue seems to mimic that of l-sb-0058-22. I suspect the cause and remedy are likely the same.
