    My PEM never seems to go below the third blue bar and also rarely goes above it. That doesn't seem right — that after a 75 degree night, I walk out in the early AM to find the PEM on 3rd blue. And if I walk out to the car in the middle of a 100 degree day with the car parked in full sun, I find the PEM on 3rd blue.

    Shouldn't the PEM temp be a little more fluid? Dropping below 3rd blue on those cooler nights and going above it on those wicked hot days?

    That behavior is normal. BUT I'd keep an eye on it. Not too much farther and you might experience Temp faults.

    Sharing experiences with my Roadster, mine does fluctuate. It does go to 2nd bar eventually after cooldown, and I get up to 4th bar driving around on hot/warm days. (2011 Roadster may be different from yours, in case that matters)

    Aspirant, Just realized your vehicle may be idle for the conditions you are talking about.
