Blind Spot Unavailable

[LKG]

Over the past few months I have had this warning a few times. It is progressively getting to be each time I start the Jeep. Once and awhile it will light up only the drivers mirror and warning, then after a minute or so the passenger mirror will light up.

I read through the threads during searches and never found what the fix actually was. I understand the dealer trip may be needed. But what is the malfunction that causes the warning and failure ?
Dirt ? Sensor ? Computer issue ?
Currently I turned it off which is ok for now.

Wasn't sure which forum to put this in so I figured I would start here.

Obviously this doesn't pertain to your issue but I think it's amusing. On narrow trails the blind spot not available message will pop up. The first time it happened, I had bushes scraping along both sides of the Jeep, the message poped up and I thought, yeah, no shit, I probably shouldn't change lanes right now.

I figured I would return with some new information.
Since this last post dated Aug 19th 2023 today being September 27th 2023 I have had the dual triangles light up both mirrors with no EVIC warning 3 times. I can not recall any instance that would correlate a common problem to cause this. First time maybe 2 weeks after the last post late August. Second time maybe a week or so later early September. Last time just the other day late September.
First time I didn't do anything and next start up it was gone and worked fine.
Second and Third time I went into settings while driving turned the feature off then immediately back on and it cleared and returned to functioning.

Currently I'm on 2.5 inch cheap lift with 37" tires. I have often wondered if the spare and its size had anything to do with it. This was never a problem in the 2.5 years prior to lift and tires.

There are a few sensors in the rear bumper (and maybe in the taillights?). Those bumper sensors can become loose, misaligned, or simply get too dirty. Touch them all to see if they're loose or not level with the metal of the bumper.

FYI, Just in case nobody has addressed this. here's what it looks like when you have the Blind Spot detection disabled, but the Park Sense enabled. The sensors in the bumper detect & alert us by beeping + display as shown in the pic below (bumper lights up).
