The only time mine wasn't working right was when I went threw the car wash when it was cold and ice formed on the bumper, and it went off every time it was in reverse. As soon as it was warm it was fine again.rrumaner said:Has anyone else that has the sonar system had this problem?
I put the vehicle in reverse in an open parking lot and the alarm goes off.
I put it in reverse in my garage and it doesn't.
I put it in reverse to parallel park and I don't get any tones.
It seems as if it is working backwards (no pun intended) and only goes off when there is nothing behind me.
Thoughts? Suggestions, other than to take it in and have them look at it?
