I have a 2015 SRT with the 8.4AN and Harman Kardon radio system with the latest software update and was wondering if anyone else has heard the sound system "pop" when the car and radio is off? The "pop" is similar to when an amp is just turn on or off and a capacitor discharges all at once. I am posting here as I don't think this would be limited to the SRT's.
At this point, I have had the dealer look at the systems to see if there is an issue but everything checks out OK and, of course, they can't reproduce the issue to diagnose. I also cannot figure out how to reliably reproduce the issue myself. Sometimes I hear it "pop" when I am walking away, and sometimes it is not long after I open a door or close a door (including the rear hatch). This does happen about 5% to 10% of the times I open and close the doors while the car is off. To add, it doesn't seem like it matters at all how long the car has been sitting.
This wouldn't be a big issue except that I have a daughter with cerebral palsy who startles extremely easy and sometimes when startled, sets her off crying. This has happened a couple times since November (month I bought it) when I get out, close the door, and go to get her out of the back seat.
Any ideas or help would be much appreciated!
