A few days ago I noticed that there appears to be excessive roll in the suspension. It appears that there is a delay between the time I turn the steering wheel and the cars reaction (roll). Is this a failed end link or could it be something else? I recall hearing a clunk at full lock turn at low speed but not all the time.

That could be you tie rods too. Does it clunk when you roll? If so that could be an axel. Either way take it in and get it checked out.

 

This could be any number of things, best to just get the car on a lift and have them check it out. You are under warranty, thats what its for
