Just for future reference for other who might experience a similar issue, I may have found the solution I wanted to post on the forum. Last week I had two more instances of issues. First, where I forget to disable the start/stop function with the button, and it stalled at a stoplight while heading to work. The car refused to start and I was stuck at the light for about 2 hours waiting for a tow. The dash screens would light up but none of my outside lights worked. For the heck of it, before the tow arrived, I disconnected and reconnected the terminals and, low and behold, the car was working fine again. The second instance happened when I parked my car and later it simply wouldn't start (appeared unrelated to stop/start). Once again, I disconnected and reconnected the battery and it was starting fine. Strange as it sounds, my Cobra radar detector has a battery check function whenever the car is started and it told me last week the battery was bad. Exploring this potential cause, I discovered that the prior owner installed a standard, non-AGM battery in the car. According the owner's manual, stop/start cars specify a AGM-type battery. I installed an AGM replacement and haven't had any problems (at least so far). Admittedly, I'm a bit nervous about keeping the stop/start function on so I've been trying to remember to keep it off but check it's functionality every time I drive the car when parking the car to see if works. So far, about 20-30 tests without issue. Just to try to increase my confidence in the fix, when I took the old battery to the auto parts store to recycle it, I asked them to use their battery check equipment to verify the battery was bad. When they checked it, it showed as 'passing'. This didn't help me feel better but, like I stated, the car appears to be running fine now that an AGM-type battery is installed. Maybe the old battery was just starting to fail (?). I hope this information helps someone else out in the future.
