Rear bumper sensor fading

Hi guys, I’m experiencing fading on the 2 rear parking sensors on the bumper (on the plastic portion). I was wondering if anyone else has this issue and the fix? I’m not sure if paint or plastidip will render the censor useless….thx

 

I have one that’s doing the same exact thing! I actually thought about taking some sharpie to it hahha

 

Pics?

 

I’ll grab some photos when I get home.

 

Here is a pic

 

Hi everyone was wondering if you guys ended up fixing this issue and if so how? I bought an extended warranty and was hoping the dealership would take care of it. But they said it’s not covered.

 

My 2021 SR5 rear ones are all starting to do it too. Would be interesting in a fix too.

 

If you guys had warranty would you fight to try and have this fixed under warranty? They said because it’s not mechanical. :/
