The factory installed alarm system may sound for no apparent reason. A revised hood latch assembly is available which should correct this concern.Google+

Alarm goes off for no reason. Keys are not anywhere where the alarm button might get pressed by accident. Started happening 5 days ago, is now happening about once or twice every day.

Alarm sounds, periodically, for no reason. Happened 3 times at dentist office; two weeks later at home, two days later at home again. Frustrating.

Alarm goes off in the middle of the night and I key fob will not shut it off. Last night it happened 3 times and I have the horn going off in my head. This should be a recall as I fell if a security system fails what can a consumer do other then go to the dealer. Toyota must know they have issues and should come clean and admit this a recall situation.

Alarm sounds for no reason now and then, Toy shop said it was hood latch switch and had to be repaired at my cost. I bought a Toyota so I wouldn't have these problems. They said wind or vibration can set it off.
Not fixed I will have to find a bypass or a temp fix until I can find a way to get it fixed
