I have a 2017 Pilot with 80,000 miles. One day after exiting the car and locking the doors I heard some strange clicking beeping type sounds from under the hood. I looked through the window at the dash and the dash along with all interior lights were flashing/blinking in addition to the clicking beeping type sounds I could hear from under the hood. It had a mind of its own. It wouldn't stop even though the car had been turned off. I opened the door and started the engine. Engine started fine and car acted normally while running. Turned the car off and for the time being it seemed normal. Next day it did it again. I took into honda and they could not duplicate the symptoms. They tested the battery and alternator. Both passed but they said the battery was about 30 cranking amps lower than its rating. They suggested I change the battery but they didn't have any batteries in stock. I went to autozone and bought the Platinum Duralast model. Problem seemed to be solved at that point. Now two weeks after installing the new battery the problem has returned. The problem only shows up here and there. Not everyday. it seems to act up just after I have a day of a lot of driving with many starts and stops (I'm an outside salesman by trade). Makes thing something is heating up before the symptoms kick in? The strangest part to all of this is the car behaves perfectly fine while running. This issue only shows up AFTER I park the car and turn it off. Some sort of voltage drop or short/bad ground is occurring while off. Any ideas would be greatly appreciated. Shops just aren't interested unless the problem can be witnessed. Right now its not happening often enough to be witnessed on demand. But that's the point. I want to fix it before it becomes so bad that I get stranded somewhere. Anyone have similar experience?
