My TX-350 with just 2000 miles just started beeping when parked and off approximately every 30 seconds. Checked all doors, lights and windows. Nothing is open. Have restarted and driven and still beeps. Suggestions?

 

Dealer time. I think I have similar, but opposite problem where system does not notice person in back seat and would not beep even if the person does not click seat belt. American built Lexus has tons of small built quality problems 😬

if you put cargo on a seat before starting the car it will not beep.

same concept with persons sitting before starting.

 

[QUOTE=sheetmetalfab;11759291]Really???
I thought that was error 🤔

 

[QUOTE=hyunwoo198;11759346]there’s a limited time period where the sensors are active.

for example a kid moves from one seat to another and the beeper goes off.
(kid has to rebuckle the seat belt in the empty seat)

i just tested this extensively on a 7600 mile road trip. (2-4 kids riding along at various points)
