WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

Check the tire inflation pressure and adjust to the tire inflation specifications as necessary.
The vehicle should not pull in either direction causing the steering wheel to be off center while driving in a straight line on a level.
Confirm that all tires are of the proper size and the same model and brand. If a mis-sized or non-matching tire model is present, inform the customer that in order for the vehicle stability system to function normally, tires need to have a uniform size and rolling diameter.
Inspect the serial data circuits and connections at the power steering control module and the electronic brake control module. They should be free from sources of electromagnetic interference and the connections should be clean and tight.
