Here is the list of issues I'm experiencing:

1. Alarm sometimes trips on its own. always at night. it has been raining a lot lately
2. VSA, ABS, brake light and flashing "D" light.
3. Key fob doesn't lock/unlock.

Looking at the problems others have had in the past it appears to be water. I confirmed as the carpet is damp below the fuse box on the drivers side. The sunroof drains are not clogged. I poured water into the sunroof tray and water gurgles down the holes and I can see it exiting the bottom of the car.

I pulled the front of the headliner removing the center light cluster and both visors and A pillar covers. The drivers side curtain air bag was damp and I could see water in the rubber door seal.

The only thing I could see is that the space between the black sunroof tray and the van body is allow water to enter (front of the van). I sprayed a hose and water does enter that gap. I'm going to seal up the gap with some silicone to see if this takes care of my water problems.

I would be interest to know if anyone else has had a similar issue and what they did to address it.

Thanks.

I've had the felt under my rug get saturated but no electrical issues. Being winter I can't tell if it has gotten wet again since I dried it out. Can you post a picture of where you think it's coming in? If you found the culprit it may help someone else in the future.

Water intrusion is common. It will ruin the fuse boxes if you don't get it fixed.

Sorry, I didn't take any pics when I had the headliner partially removed. Anyone who has this water intrusion into the cabin should remove the a-pillar cover to see if there is moisture in the curtain air bag. The leak is most likely a clogged drain hole. Remove the visors and center light array (4x 8mm bolts) to remove the front of the headliner.

I placed a hose on the roof for 10 minutes while the headliner was removed. I could see water exiting from the front fenders and no water was entering from the sunroof tray. I didn't seal with silicone as was my original plan. I don't believe it was the roof rails as the headliner was not wet or discolored indicating water. There was no water entering from the windshield either.

I did remove the aftermarket sunroof wind deflector that may have contributed the leak issue. I left a fan on the fuse box and some dessicant to dry up any moisture. There are no lights on and the FOB is working. I have the horn fuse back in so I will see if the alarm trigger again. Rain is in the forecast in a few days so I will report back.

Had the exact issue plus most of the guages were on (key out) fuel gauge etc. Engine wouldnt start but when it did it kept running when I removed the key.
I removed the fuses by drivers foor one by one think it was the #5 interior light everything normal with it out. That was after a heavy rain.
Even after it dried it wouldnt go away.
