LEFT AND FORWARD COLLISION WARNINGS SUDDENLY very active

[Hebden]

Today, for the first time have had multiple red collision and P warnings on the left and front. Having read through the manual these are definitely parking sensor warnings. Nothing really to cause this.  Is it likely to be a camera or sensor fault or is there a recall of some kind out? Also wondering if anything has accidentally been adjusted or reset.  We usually set off with the forward white line crossing turned off.  Appreciate advice.
