Re: mysterious cruise controlHad both the shop and OnStar scan for codes(a nice feature) , none. Just
brought the car in to the shop they said the cruise needed a software
update, there is a TSB on it. I'll try it for a few days and let ya know.
I haven't tried pulling the steering fuse. I attribute the drifting to the
overly sensitive electronic steering and the condition of the crummy roads
here. On a smooth road, my car will stay relatively straight. Never seen an
ION that held a hands-free straight line for as long as an S-series,
something to say about plain ol power fluid assisted steering.
