Does the blis system go bad? It is only detecting cars randomly. I tried wiping off the lens with no improvement. Anything else I should try before going to the stealer?

 

Could you elaborate on randomly?

 

Are you out of warranty? If not, take it in. Warranty issue.

 

my 2016 messed up infrequently, but it was giving the red backup warning when nothing was there.

Agree if it's under warranty, head to the shop.

If it's not, well......just the sensor replacement in my tail light was over 300 bucks....
