I would say something might be wrong. I know when I start mine in the morning, it'll just about run me out after about 10 minutes. Nitro doesn't have a spot in the garage yet and it's been in the low 30's over night.Ok, I picked up my Nitro 2 hours ago. Does anybody else have a problem with the heater performance? It just never seems to heat up inside the car. Makes a ton of noise but just doesn't seem to do much.
