Re: Serious Steering Problem
I can't recall ever seeing it on a new car, doesn't mean it can't happen though. So you're saying this has been like this since new? You just lived with it? Mighty tolerant person if that's the case.
I assume you understand road crown and that it is not your issue in your opinion. Letting go of the wheel and having it move one way or the other is normal due to road crown but it would be something you could duplicate on another similar vehicle too. If you take another '13 Malibu down the same road, does it do the same thing? I doubt you will find this to be the case here, I think you have an issue.
In the old days, if you did the over center adjustment too tight on a steering box, you lost the center of the steering box. The wheel would be right or left of center but there was no center. These late model electric racks are pretty good, or at least I haven't seen one bad yet in this respect, let's just say that.
You may very well have the dealer say this is normal. I haven't driven the car, I'm just going by your description, going by that I think there is an issue. If the shop foreman or service manager drives it and says it's normal, have them get another '13 Malibu off the lot and you drive it and see if it does the same thing as yours.
I think, going by your description, you have a calibration issue with the steering angle sensor for some reason. Hopefully the dealer scans the whole car for codes, even though there are no warning lights on by your description, it only takes a couple minutes to check. My next step would be to check for PSCM calibration updates, not all updates have bulletins to alert us as techs to the updates existence. The latest calibrations are an absolute must anymore when problems arise. We fix quite a bit with calibration updates alone sometimes. After checking/updating the PSCM calibrations as required, I'd do the relearns I spoke of in my first post, then retest the car. If the problem still persists after that, I guess I'd do a quick alignment check and then maybe a call to Technical Assistance from there to see if there are any other cases of this type of thing.
It is absolutely not normal from what you describe, nor should it be expected. Still, not everything is always perfect right off the assembly line either. One way or the other you need to address this though. Good luck.
