Ok guys. I have a small issue with the Z that is driving me up the wall. Dealership says this is normal and that they compared it to a new Z and that it's fine. My car has 7k miles on it btw and totally stock suspension, tires, etc.

If I'm driving on the highway and I make a gradual sweeping left turn and let go of the steering wheel the car will continue to turn left. The steering wheel does not straighten out unless the turn is more than "gradual" in which case it will "straighten" itself into a gradual left turn.

If I make the same gradual sweeping right turn and let go of the wheel, the car immediately straightens out, which is the behavior I would expect.

If I am driving straight the car might go straight or it might try to veer left, but it will NEVER try to veer right unless there is extreme road crown or bump that pulls me right. This behavior is MUCH more noticeable when it is cold. In the dead of winter on a 20 degree day after the car has been sitting it is downright PULLING left until something warms up.

Sometimes if I'm braking to a stop, and more consistently if the road is slightly bumpy, just a moment before the car comes completely to rest, the wheel will want to turn left quite a bit (1/4 turn or more). This never happens where it wants to turn to the right.

The effort to turn left is noticeably less than turning right. I'm not talking lock-to-lock turning, but the little left and right adjustments you might make to stay in a lane on the highway.

Visuallly, when driving the car straight, the majority of the time the steering wheel is turned to the left a few degrees (less than 10 degrees). This never happens where the wheel is turned to the right to maintain straight travel.

I've had the car in 3 times for this and every time I get the same story. "It's normal". "It's road crown". "It's aligned". When I got the car It did not feel this way. I hit a curb with the back wheel and replaced the back wheel and the lower swing arm, but it has never felt the same since. They even put it on an alignment rack and measured it and it aligns perfectly with the Nissan specs. I have the printout to prove it.

So guys, take you car for a spin and let me know if you have any similar behaviors. If you have any thoughts what it might be, I'm all ears.
