Toyota Avalon trunk lid keeps opening

djb8

I have a 2006 Avalon XLS with 62,000 kilometeres on it.
The trunk lid sometimes opens by itself when the weather is hot and humid, or when it rains. When the lid opens, I hear the beep just like when I use the Fob. Sometimes I can't get the lid to stay closed until I start the car. The dealer does not seem to know how to correct this.
Has anyone else had this problem?

Thanks

I think the problem lies in the remotes for the vehicle. IIRC the car only beeps when the trunk is opened with the remote. If you open it with the button in the car it doesn't beep. Try taking out the batteries of your remotes and see if the problem goes away. If it does there is a good chance one of your remotes is the culprit.

Thanks for your reply. Most of the time when the trunk opens I am not anywhere near the car, so the dealer does not think it is the remote.

Thanks again.
