While driving on a state route I hit a bump in the road and immediately felt the steering wheel shift from even to the left about 45 degrees with a thumping sound . Also the stability light came on. I tried to steer the car properly but encountered a pulling to the left. I pulled off the road into a lot and discovered the rear left wheel and side (driver side} was lower than the right and the wheel was tilted inward. Further inspection revealed that the connection to the suspension was compromised. We had the car towed on flatbed to my local mechanic. He is located near the local Nissan dealership so we hope to get it resolved with his selp. My research on your site indicated that several (1000's) of 2013 vehicles experienced this problem but not many 2014 models. I believe the problem is not just for the 2013 models and the 2014's age is about at the same time when the 2013's have failed. (6 years old). I am hoping that Nissan follows suit with the 2014 models like canada did last year.
