“Gm removed my engine block heater in july. It is now december and the forecasts call for single digit temperatures. Contacted GM and the dealership and they have no idea when I will get the new engine block heater installed.”

NHTSA complaint #11287658, filed 2019-12, 20,000 miles

“Diesel l5p 2017-current. When having the engine block heater plugged in, I have seen multiple trucks burn down from having a short somewhere. I have also seen the cord for the engine block heater rub against the wiring harness and rub the insulation off exposing the bare wire. I believe when this happens, an electrical arch jumps from the wire to ground a starting a fire. Please investigate engine block heater cord and it rubbing against sharp edges exposing bare wire.”
