Thanks for the info, the alert only comes on the screen when shifting into gear, D or R. I also noticed it showed when making a sharp left or right turn. But there is no continuous chiming, and removing the child seat does not have an effect. The alert clears after the vehicle has been turned off and parked for a while on its own... I have emailed tech support videos and pictures with a description and time stamps so they might look at the logs. The only mechanical thing I noticed was a bit off was the cover plate that glides behind the monopost springs forward suddenly when I move the seat using the easy access button, causing a single thump. The other seat does not do that.
