I just experienced several major electrical issues when water backed up in the sunroof drain, went down the headliner, and into rear of the dash. It caused the rear trunk to open during a storm and it shorted out a rear panel on the left side after it flooded because the drain was clogged in the trunk area. (make sure that is open, too.) Over $1,000 repair.

Make this a once a year maintenance task.

 

Sorry for your trouble, Daspyda. But thanks for the suggestion.
Did you clean all 4 drains?

 

Would you recommend doing something like this to clear out the drains?

 

My Indi did as part of the service. I would do so if you do this yourself as you're already there with the needed tools and supplies.

 

I didn't want to remove the liner since it takes time and efforts and what I did was to use a bore scope camera and find out where the drain holes are as is posted here almost 2 years ago. It has been OK so far but I think I have to clean those drains in accordance with Daspyda's suggestion soon.

 

one thing to remember is water must pass the seals to reach the drains. So the assumption is seals are not good, if drains are not good, problem. It's like saying your suspenders snapped, and your belt broke too. At this point you better keep an eye on your woman and your dog.

Very common on 4th gen Maximas, the drain goes into a metal Y with the power antenna. That breaks and water pools in the trunk. Why even in Calif you can see some with rusted out rear right 1/4s
