Occasionally, when the 2016 Trax has been sitting outdoors in 0° weather, I start it up and there's the smell of burning oil, and blue smoke comes from the tailpipe. After driving a mile or so, everything's fine - no smell, no smoke. Then it won't happen again for a few months.
I've had it to a Chevy dealer service center, a Meineke, and a privately owned mechanic, and no one can find a problem. Any ideas? Thanx!

May just be oil sitting in the intake from the PCV system which isn't the best design on these. Make sure the PCV regulator hasn't started to leak on the valve cover. This problem starts with a pin hole and very gradually gets bigger with time until you get the trouble code by then it may be too late. If you have any erratic idling this may be the beginning. If putting your finger over the regulator hole improves idling then you found your problem.
