Steering problem/question
At slow speed (idling around parking lot type speed)when I turn the wheel and let it go it doesn’t return. I can go in circles. Every vehicle I have ever driven will straighten it’s self back out. Once I get going down the road it is fine. Any thoughts?

Just had an alignment last week and it’s still doing it I thought it would help, but it didn’t. What is Ackerman effect? If it’s the wide tires wouldn’t they all do it. Maybe they do I’ve never driven another one.

Your C5 is equipped with a function called Magna-Steer (it's also officially called VES, or Variable Effort Steering). Basically the way it functions is depending on what speed the car is traversing either more or less power steering effort is applied to the car to make the car steer easiest for whatever driving situation the car is in, i.e., if you are in a parking lot, the system will be working at high capacity to make parking lot steering really easy.
The system works off a combination of the SWPS (steering wheel position sensor), the power steering pump, and the EBCM. If any of those items are failing or have failed then the system will default to the "highest boost" (as in applying the most force to the system) at all speeds.
It does ultimately sound like the system is working correctly for you. At parking lot speeds there will be a lot of force applied to easily turn the wheel, but it should not return easily. If you are at highway speeds and the steering feels exactly like it does in the parking lot then there is a problem.
