How often has your parking sensor malfunctioned due to it being frozen?

It's happened to me twice with the temp below -4 (25F).This morning it was -6 (21F)and put it into reverse and got a continuous tone which didn't clear until I put it into D.

I presume this is the parking sensor causing this?

 

I've had problems when the parking sensor was encased in ice and snow, and I've even had false alarms due to heavy amounts of snow falling in front of the sensor, but never just from it being cold, even at 2 degrees Fahrenheit.

 

It may be a build up of frost on the sensor

 

i have had this happen a few times...i had it happend when the road was clear and i was driving and it went crazy on the open xpressway with no one in site!! i would say that the cold does have effect and like the other members have said the snow and ice will also.

 

Doesn't it mention in the manual that cold and/or wet weather can do this? I believe it mentioned that on my old FJ Cruiser with park sensors.

 

actually mine is doing it....daily. annoying.

 

Just a reminder that you can turn off the parking sensors using the control panel near your left knee. I did this for a short time last year when my sensors got encased in a thick coat of ice.

 

I thought the front sensor is disabled after you drive faster than 5-10 mph?
