Do you have a hitch in your receiver?
I have had issues with the sensors and remedied it by removing my trailer hitch from the receiver. It is a larger hitch with provisions for load distribution, so it was big enough the sensors saw it and would go crazy.
Just observed the bubble for this frist time this week. Never saw it before but I figured it was because I do not have many of the assistive technologies (no 360 camera, no copilot).
Rough Country UCAs fit, but there is no provision for the headlight adjustment sensor found on higher trim levels and a custom bracket must be fabricated to retain its functionality.
