Hello guys. Long time lurker here. I'm having an issue with the electrical system with my CX5. After washing the car the blind spot indicator sometimes flashes with the turn signal and it seems after it dries out it goes away. This was livable but now the problem seems to have worsened with draining the battery everyday and I now have a keyless entry malfunction message appearing. This is what I've done so far:

1. Replaced vehicle battery in Dec 2023

2. Pulled fuse to trailer wiring in case there was a bad connection. (The trailer plug was ripped off by the previous owner)

3. Checked fuses and no issues there.

4. Checked grounds in engine bay and all look fine.

I noticed the worse issue with the damp wet weather we've been having in Canada. Has anyone else had weird ground issues with their CX5? Thanks!
