one month ago,i turned the car too much,so it hid the side of the road. the steering wheel was askew,so i took the car back to dealer for reparing. they did the 4 wheel alignment. the steering wheel is straight now,but sometimes when i stop the car for red light. the steering wheel turned itself to right or left automatically,so i have to make it straight.is this normal ?

 

I would take it back to the dealership that did your alignment, something isn't right.

 

I'd like to know what the deal is with that issue when you find out. I have the same problem but only on roads that aren't flat. My car has always driven that way though. I just assumed all Zs were like that.

 

Sometimes it's a warpped rotor, scarred rotor on the side it pulls to, if consistantly. Otherwise, a loose end link might be the issue? Take it back it's not right. I also have noticed certain tires seem to be like that. At least on my old Z with some tires the car was squirrely on the road and coming to a stop. I just thought it was worn components with 200K on her. I rebuilt the front end completely and still there..... later, I replaced the tires and it ran straight tire smooth and didn't pull anymore. DOH !!!
Now, I realize how different tire construction can affect you car. Those we Yokohama tires A008's. I put on BFG Sports and couldn't have been happier. Just weird ....

Here she is ... the old Z:



If '07 comes with T-tops I'm in trouble .... loved those tops !!!

 

If it's an intersection where 18 wheelers travel often they can put grooves in the road and your tires might be following the grooves. Every vehicle I have owned does this in a few spots around town. As soon as I slow down the car cuts to the left at one particular spotlight.....doesn't matter if I'm in my Z, my truck, or somebody else's car. I just assume it's from heavy freight breaking right there or it might just be the way it was paved, I dunno. I just blame it on the big rigs cus I hate em lol. Always throwing rocks and **** at my cars.
