I have used my remote start most of the time which could bring on different glitches like for example no heat in cab motor is warmed up fan is blowing changed settings floor to vents to air condition back to heat but no heat and this was the coldest day of the winter minus 35 - 38 Celsius ask me if I was impressed.I was fit to be tied by the time I drove to a dealer in which they said you are the third customer today with the same problem, I am a snowmobiler for 40 years but I never froze as much as being in this truck, drove it in the garage they cycle through all the setting for heat and venting yup it's cold shut it off restarted it and guess what heat.The other day remote start the truck no sound coming from the radio shut it off turned it back on and there is sound obviously I didn't pay enough for this truck not impressed if it's going to have a different problem every time you use the remote start.
