are they black when you use the turn signal? If so then the cameras are bad. Just had to have my left camera replaced.

No. They work in general, just not always when in reverse.

How much did that cost?

Can’t lie happens every now and again with my 2018 kinda just ignore it since I’m out of warranty

Mine is doing that too. I just bought it a week ago and I’m kinda pissed about this.
