The wife drives a 2014 Chevy Equinox. It's got 61K on it. We took it to Alva yesterday and, while in Alva, the "Service StabiliTrak Sytem" notice came on. Some pretty hard curves between Enid and Alva, but no slipping or sliding or skidding. No noticeable difference in handling. It's been shut down and re-started several times since then (which the owner's manual mentioned doing). Turned the system off, then back on, a few times and made no difference. We put the son's Bosch code reader on it, and it doesn't throw any codes. Ideas?
