NHTSA Complaint #11568772 — 2017 CHEVROLET SILVERADO 2500

I was driving with my front and rear motoried window defrost on because its cold outside right now when I started smelling something burning. I turned down the defrost knob. I opened the driver side window to air our the smell when suddenly the rear motorized window defrost sparked up into flames while I was driving. It was in full on burning up in flames. I pulled over and luckily I was able to put out the fire. I have contacted GM because when I google this issue it states GM put out a recall on 2014-2019 Silverado HD trucks but upon speaking with a GM customer representative my truck there is no such recall on these trucks. I could have been killed or worse killed someone else on the road. I am considering getting a lawyer involved with this issue.
