Had this car for 2 years no issues. Now all sudden when it rains alittle. An I drive my car an go to back up it slams it breaks on me. I took to Nissan dealership in Johnstown told them what was going on and she told me that it had dirty in the sensor. Ok could have been. Well now everytime it rains I have issues an when I back up it slams it brakes. I have got stuck in the middle of the road several times. I’m either gonna get hit or hit someone an Nissan is pretty telling me there is nothing wrong with my car
