On my '07 LTZ, my back up sensor beeps when the first yellow light comes on and that is it...it does not beep when the 2nd yellow light comes on or the red light...whats up?

 

Mine behaves the same way. I thought it would start beeping faster until a constant tone like Ford's (egads!!) backup sensors.

 

Yep. same with mine. I've already run into a wooden stake I didn't know was there and it didn't start beeping fast until I hit it. Never trust it.

 

Same here..I don't trust it.

 

Yeah, same here, not the most reliable!

 

Thanks....I trust it pretty good to two yellow lights, but then after that, I start making two point turns if necessary....as far as I am concerned, RED means you hit something....I do like the back up camera..it is very accurate.
