I got my '18 Touring in April, pre-owned with 3600 miles, and from day one the front parking sensors have gone off randomly when I'm stopped at a traffic light. Sometimes it's a very brief one-alarm beep, others it's a 2-3 second three-alarm alert. Has anyone else experienced this? I've seen some random posts on other sites but want to check here. Would this be something for Honda to recalibrate, and would this potentially be under warranty to do?
