My car is only a week old. I noticed today on a cold start, first start of the 90 degree day, it was immediately at 4 bars (or at least it was there after only a minute or two when I thought to check it, having not noticed it displaying less bars previously), which is where I would expect it to be when warmed up. It didn't start with no bars or fewer bars and light up more bars as it warmed up, which is what I would expect. Is this normal? I doubt that it is, I know it's not a super-helpful gauge, but I would expect it to display more bars up to the normal 4 as it warms up. Coolant looks to be at the normal level.
