I have a 2011 SCREW, 4x4, with 17,000 miles, completely stock - no mods.

Maybe around 15,000 I started noticing the steering not responding like normal. It's not all the time but random and usually when at highway speeds. The truck may begin to drift a little and I'll try to correct it, but there seems to be a slight delay before the tires respond to the steering wheel input.

At first I thought I was just imagining it but it has occured enough that now I think it is something. Anyone else notice anything like this?

It is random so I'm guessing it's a waste of time to take it to the dealer, unless it's a code they can read or something.

 

This could be a serious safety issue if you need to swerve to avoid an accident. I would take it in anyway.

 

X 1,000,000

If it was the engine maybe you could wait. Brakes, steering or safety components? I would hate for that to be your last post, friend.......

 

they can test drive it on the highway with you...

 

Look up EPAS. Get it fixed. I had the same issue around 6000 miles. It took me 32 days start to finish... hopefully you have better luck.
