Story is still unfolding. Took it to the Chevy house Friday, they had it all day, said they found a "chafed" wire in the steering column. Repaired it and ran a scan, "everything read good". Took it on a day trip to visit my youngest son in Manhattan, Ks at Ks. State University and got about 20 miles out of town when the "security" light came on. Stayed on for the 160 mile trip. Back to the shop this morning, had it all day, idling, light never came on. Wife brought it home after work and plan is tomorrow after I get home from work is to take it out of town for a spin and see if the light comes on again. If it does I'm headed straight to the Chevy house. This is getting old, real quick.
