Same issue here. Sometimes I come out to find that my trunk opened (from the key fob in my pocket).

Yup. I had the exact same issues.

To prevent the lock/unlock cycle, like the others said, keep the keys in your car. Or let it just keep locking and unlocking (like I did, since it didn't bother me).

For the alarm issue, there is a TSB. I still haven't been to the dealer to fix it.

For the trunk issue, it's because the button on the keyfob gets pressed easily. Happened with my wife thrice when the keys were in her pocket and she bent down to put on her shoes (trunk popped open). Hasn't happened with me since I wear loose jeans/pants.

Same problem for me, right down to the alarm going off. I leave my key about 30-40' from the car now when washing and don't have any issues.

I will do that when I'm back home but you should be able to find it on this forum. It's in an earlier post. I had printed the tsb number off from the prior post and taken it into my dealer.

This could be wrong but a google search yielded this. I remember the other thread but I can't seem to find it now.

I had the same thing happen to me the first time I washed the car. After a few minutes, I just put the key fob inside the car and that solved the problem.
