I woke up to my alarm going off this morning, went out to turn it off and inspected the car for any damage or signs that someone was trying to break in. Nothing of the sort so I went back inside, the alarm started going off again. It went off about 10 times before I decided to go to the dealer. They did a battery check, passed their tests, no appointments available until late next week so I went on my way.

I got home, let my car in the driveway and didn't hear my alarm for 2 hours. I left in another vehicle for a bit and came back 2 hours later to a dead battery. The lights on the side of the car in front of the front doors were dimly flashing, and my gauge cluster was flashing when I opened my car door. Put the key in, tried to start it, nothing. Took the key out, and the gauge cluster started blinking again (not an engine light blinking, the whole tach/spedometer).

Any thoughts? Car is an 08 TL Base, with the original battery. I initially thought the battery since it's never been changed, but the dealership said it passed their test. Tried reading up on it, but couldn't find anything solid.

 

Charged the battery up and hasn't acted up since... Thinking something to do with the heavy rain we had, possibly a leak somewhere (windshield??). Having the Acura dealer check it out this week to run the alarm codes and see what tripped it.

 

Check your sunroof drains.

My sunroof drains were clogged and water ran down the A-pillar into the fuse box. My alarm kept going off, I couldn't unlock the doors with the remote, windshield wipers only worked on fast, and the turn signals didn't work.

 

Haven't messed with the sunroof before, where are the drains?

Much appreciated!

 

Had the dealer run the codes for the alarm, there was a "body code" pulled from it saying "Lack of communication with the front drivers door".. Dealer had no clue what this meant.. anyone get this happen before?
