My 2017 Grand Caravan seems to have maybe an electrical problem. It has 82K miles,only driven about twice weekly for 60 or so miles and occasionally will take a short trip of about 200-300 miles. I've noticed when connecting to my cell phone via Bluetooth lately it skips a lot of the conversation as well as reading text messages received. The dash clock is now losing time and one of the sliding back doors seem to be slower to open (but, that may be me expecting electrical trouble). My car battery is about a year old. Suggestions?

Thanks,
