We have been having a rhythmic clicking sound that almost sounds like a small washing machine that occurs when we turn the van off. It sounds like it is coming from the dash. The sound shuts off after about two minutes and only occurs when the vehicle is off. If you open a door, the sound starts up again. Otherwise, the vehicle has been running fine. Has anyone else experienced this? 2018 Hybrid 10,000 miles. All recalls and RRT’s completed with no issues found.
