Take the batteries out of your key fobs and see if that cures the problem, your fob could have an internal problem that trips the trunk release.

Thanks for the response and I'll try that. If that is the solution, then do I need a new fob or what so I do?


i know its a old post but just in case im answering this question. So its actually the trunk switch is getting moisture inside. what i do is i take off the switch. blow the water out and add a lil bit of silicon around the rubber. thats it snap it back in

I had the same issue. They said I must be hitting the trunk release button on accident. I didn't even have the key for with me when the trunk popped open. The dealer reprogrammed the switch so it would have to be hit twice to open. Hasn't happened since.
