Problem or just a nice feature?

New to Jeeps, but in my other vehicles it took quite a while for the temperature to get up enough to use the heater.

In my new 2012 JKU, I can pretty much fire up the heater in the morning and by the time I get out the driveway, I'm getting warm air.

My temp gauge runs consistently in the middle. By the time I get halfway down the block, it's 1/4 way up and within a half mile, I'm the gauge is at 50% and stays there. In previous vehicles, I'd have to drive for 5-10 minutes before getting any heat and getting the gauge up to operating temps.

Is this just a nice feature in the Jeep or is it warming too fast?

Completely normal. You can broil a steak with the Jeep heater, and your engine temp gauge will always be in the middle, unless something goes boom.

welcome to owning a jeep. they have some of the best heaters of any vehicle on the road. I haven't owned one yet that didn't run like that. Heck even with a shot blower motor my old XJ would still get warm in the cab.

My heater is like a blast furnace--turned up all the way, it actually hurts if it's blowing directly on my skin anywhere near the vents. The temp gauge sits comfortably in the middle at all times once the jeep warms up. Everything you've described sounds normal to me.

In February I was in the Allagash (far north Maine) coyote hunting and at -22F I was warm when driving on the logging roads and frozen 'skidder tracks'! BELIEVE me I had heat in an amazingly short time after start-up.......one of the single best things about my JK.

I had the top off and the temp dropped. I had feet on fire and a frozen head.

Great heaters and AC. Infact on a frosty morning not only did the heater defrost my windshield quickly it got the mirrors to not sure how that happens but it did it and I dont even have heated mirrors.

Sometimes your Sight Optical heat transmission index, (SOHT) can be quite high--depending on the amount of coffee you've had for breakfast !

Yes my TJ's heater actually warped the plasting for the defroster above the dash and the plastic right above the window.

Heheh. I've perfected the hunched back to get my face down into the blast zone. If there's no passenger, I reach over and shut the far right vent as well to force more air to the driver's side.
