NHTSA Complaint #11442437 — 2013 CHEVROLET TRAVERSE

While driving 65 to 70 mph on the freeway, vehicle suddenly shudders and dash state "engine reduce speed" and "service stabilitrak" and "service traction control". It has happen about twice a month 6 months back. Took it to the dealership, no code so they couldn't find the issue even though I should them multiple videos. Today the vehicle shut off while driving 65 mph this morning in the fast lane. Luckily my wife put the Emergency lights on and we wasn't hit from behind but cats did brake fast and almost hit us. So far vehicle has left me on the side on the road 3 times today. Errors codes that are coming up is P1682 and c042-00. It also states replace ignition relay switch which I had done 3 times already. Once this happens I have to wait 10 minutes, then restart, then shut off, then reatart, then shut off then restart until to vehicle starts up how it should start up with no hesitation or shaking. Then I can make it home My fear is my wife will be driving and car shuts off while driving on the freeway with the kids. I know this issues was recalled with the traverse 2009 and 2010 and some other vehicle gm made.
