Hello guys,
​​​I am experiencing and issue with my front parking sensors, they usually start making sounds when im driving and no one is near infront of me. Just by themselves.
There was a broken sensor which I replaced and now all the sensors are good, but they still make sounds randomly even if there is no one near me. What seems to be the problem?

 

The G37's sold in North America don't have front parking sensors, so it might be difficult to get someone with experience to help.

 

I had the same problem but back sensors. After my car was rear-ended all sensors were replaced by a bodyshop, but there was random incorrectly reading of from the sensors. The bodyshop gave up and gave my car to an infiniti sealership to fix the problem.
Apparently the bodyshop damaged the cable and improper installed sensors (some of them incorrectly positioned).
