My 2011 was running just fine until I took it in for routine servicing at the local dealership. Now when I am driving at slow speed the steering becomes very stiff and hard to turn. I hear no changes in the engine and no check engine light.

Also, after having the plugs replaced by the service department, the car now idles rough at a stop. What in Gods name did they do to my car?

Steering issue sounds like air in your PS system that needs to be bled out. Did you authorize any power steering service?
A GM dealership did this?

As far as the rough idle goes, you'd need to disclose your specific engine for an accurate guess on what's wrong as plug replacement procedures are different between DI & non-DI engines.

You mentioned in another thread that your battery was (poorly) replaced. It's possible that the throttle re-learn procedure outlined in your owners manual wasn't performed after replacement.

Either way, sounds like they did a bang up job on your car. Maybe the mechanic called in sick and the detail kid was slow on work.

Oddly, I was just reading the recommended service needed for 100k provided by the service department and they mention that the PS needs "flushed." And now I am having steering issues?

I have contacted them about this and have yet to hear back from someone who can help. I have the 3.6L with the 6sp auto. I love the car, and it was running so well and now it has all of these issue. I should never have taken it to the dealer's service department.

Have you checked your power steering fluid level? I doubt that the dealer did unless you specifically asked them to or complained about power steering issues.

I did today. The Service Power Steering message appeared in the DIC. I did some reading and this video shows that it might be a wiring issue.

Odd, I take my car in to have the battery replaced and now my seat heaters and accessory plugs don't work. (I find two missing fuses)
I take my car in to have the spark plugs replaced and now it idols rough and I have a steering issue.

I sincerely believe that the dealership here in Vancouver WA is deliberately causing issues in order to facilitate more repairs.

Hopefully that wiring issue is the problem. That looks like an easy fix.

I would definitely find another shop for future service.

As mentioned already, the rough idle could be due to no tps calibration after the battery change. The procedure is in the owners manual. You can do it in a few minutes.

Good luck.
