Gurgling sound behind dash
My 2017 Pacifica Touring L (gas) with 66k miles has developed an occasional gurgling sound behind the dash. Sometimes it's heard after shutdown, about the time you can hear the shutters do their auto close. Sometimes it's heard on startup. But again, it's occasional. All started about a week ago, coincidentally after I did a UConnect update via USB stick (which went well).
Looking online, some say it's coolant or something with the radiator. Sound like a problem anyone else has dealt with?
