My Lexus RX450 2016 started doing this last year, you it went off 22 times in 2 days, always at night. Lexus said that the alarm is very sensitive and there was nothing they could do, they cleaned out the interior and said it may have been spiders moving about. That cured it for a while but this year it happened again, also at night. I took it back to Lexus and got the same result. I took out an extra two years warranty and their work cleaning was free, the waranty has run out now so I am waiting for the next time it goes off. If anyone comes up with an answer please let me know At the moment I feel that the car is not for for purpose.
