Hi
Over the past three or four days. The factory alarm in my 2006 is250 manages to set itself off randomly throughout the day and night. No idea what is setting it off. I've tried locking it with the key, leaving it unlocked etc but it still manages to go off. Making it very hard to go anywhere to do jobs as I have to keep disconnecting the battery. Have called Lexus in Perth, Australia where I am based and they have said that in order to figure out the problem, they will need it in the shop to wait for it to go off.. At the price of $180 an hour so I am trying to find out if anyone has had a similar problem and would happen to know any causes and or fixes
cheers
