I'm having the exact same issue with my alarm system on my 2008 Highlander that I just purchased on 09/20. It goes off randomly for no reason and I think my co-workers are planning to put a hammer to it soon. Did you ever get this resolved? If so, how did the dealer resolve this and which dealer did you take it to? I'm bringing mine in next week and want to give the dealer something to work with.In the last week, several times when I have left my '08 Hylander, and locked the doors via the remote....several minutes later the alarm was going off. Has anyone experienced this before? No windows or doors have been open.
'08 Hylander Sport
doesnt matter how you lock it. it's the hood latch switch thats acting up. i had my car for 9 months and it just started to act up last sunday.Just curious, I have a 2008 highlander hybrid model and haven't experienced it eversince. Is this a model wide problem for the 2008 highlander? Well, I locked the car by pushing the black button in the door handle, very seldom I used the remote. Does it matter?
