Same here. I had the stupid thing bump about 6 times. I noticed that my rear door lock would not unlock/lock off and on. Then one day it just died. Then a few weeks later the other side died too. Replaced both door locks. Tip if you DIY, be careful when taking off your door panels. The corner is kinda tight and if you have the crappy sticky/cracking door panels like me, I took a huge chunk out of my door panel.
With all my other cars, never had I had a crappy dash nor have multiple door locks failing,. Lexus is a POS and I am counting the days to getting rid of this turd.
