I don't post here all the time but I do read quite often. Searched high and low and Im not able to find much.

I have a 2011 Coupe AWD and completely stock. I am the second owner of the car. More recently I notice the car is all over the place (highway speeds). Almost feel like wind is pushing me back and forth. When getting off an exit theres that feeling that the car will either flip or spin out of control

Just had brakes done in the front and mechanic said my end links are shot.. car is under warranty and dealer says they cant replace until they actually break off..according to SA they have some play purposely to give the car better handling.

Any ideas what could be wrong here, tires are in good shape too.

 

What tires are you using? Are they all the same?

 

yes all the same. Not sure of size but the car came with m37 wheels

 

If they are good year rsa then that's the problem those are horrible tires come on the g37 same happened to me when I got my sedan, not sure if the m37 wheels came with the same tires

 

come to think of it they are hankook ventus (v12 possible)

 

could the sway bar end links have anything to do with it. Car just wont stick to the road. Even Steering wheel feels loose.

 

The steering, tires/wheels, and suspension need to be thoroughly examined. You likely have a loose, worn, or broken part somewhere.

 

That what I think. I had the car at the dealer and they say well it is a 2011 what do you expect.. or the car runs perfect.

 

If you have worn out suspension parts its easy to cause the alignment to get out of spec which can cause excessive movement at speed.

 

Take the car to Infiniti, get a thorough inspection done. Once they have determined the issue, order the parts online and get installed either at dealer or other shop to avoid the general stealership fees

 

I would purchase some new sway bar end links (stablizer bar link on ROCK AUTO) and get those installed. After new links are on then go get your tires balanced and aligned. I attached a screen shot of the links for your car on rock auto . com

good luck.

 

There should be no visible play in the sway bar end links.

The worn sway bar end links have no effect on highway stability, and you won't notice anything different when you turn.

I would have the suspension inspected and get an alignment.

 

Just for fun, what's your tire pressure?

 

My guess is either tie rod, or sway bar end links. More so tie rod. Just a guess.

 

I'd get the alignment checked, tires may be tramlining which can feel very unstable at higher speeds, Some tires are much more prone to this than other, not sure about the Hankooks. How many miles are on your car, and on those tires?
