The parking sensor, near driver fog light, keeps beeping when back up or in drive at slow beep. I thought snow or leaf sticking to sensor, but it doesn't go away after a car wash. Any similar experience?

 

I had a same issue on my Canadian 2016 RDX Elite 1.5 months after purchase. Washed my car, cleaned the sensors' surface. Nothing. Took it to the dealer and had them replace the sensors. This did not fix the problem. They then replaced the entire module that controls a few sensors. That fixed it. No problems since. Its been about 5 months now.

 

These sensors seem to be a growing problem and I just had my rear sensor replaced

 

Dealer unplugged my sensor while waiting for part. A real concern for those who keep it long. Not a concern for me as I keep car 2, 3 years. But troublesome as I have to take day off. Single problem normally takes 2 visits if part order needed.
