Re: Problem With 2014 Grand Cherokee Heater

I just read through all 9 pages and its very unsettling to me that no one from all over the map found a resolution to rectify the heat in their G.C.. I too am experiencing the same issue. I bought the G.C. Summit on 12/24 and the next week the heat was really bad. The Jeep was built 11/2013. This is the third day its in the dealer to "fix" this issue. I hope they can resolve it. My radio jams if I use the usb or mini sandisc. I spent over 53K and I feel like I bought a 16k car. The way things look I'm glad i bought the MaxCare Warranty. That suspension can be very expensive. I hope one of us can post a resolution here soon.

Re: Problem With 2014 Grand Cherokee Heater

I called Jeep care today 1-877-426-5337, of course with tier one person who could tell me nothing. I am to be getting a call back from them supposedly within 1-2 days.
If they cannot resolve it I will happily post the video to Youtube and link it to any Jeep review I do on the car sites. Let's hope they can fix it, since other than my Jeep Sauna car things are going well.

Re: Problem With 2014 Grand Cherokee Heater

I had the overwhelming heat for one day after having one of the updates (not uConnect) done at the dealership. No matter what I did it just kept blowing hot air. I couldn't get back to the dealer that day, and by the next day, and ever since, my 68 degree setting has been holding OK.


In that one day I learned how frustrating and uncomfortable that can be.

Good luck to all of you.

Re: Problem With 2014 Grand Cherokee Heater

An update for my personal situation:

The replacing of the sensor does seem to have helped. It's no longer extremely uncomfortable; unfortunately, the system is still very sub-par. I've been waiting for a while to see what would happen.

At least now I'm not getting completely frozen when it's cold outside, but it still does not maintain temperature very well in any given conditions. I get cold air when the cabin hasn't warmed up yet sometimes, but it's only mildly cold.

I'm going to leave it alone for another couple of months and see what happens. I'm a bit afraid that I've gotten to their "nominal" working state, and it just really isn't very good. At least now it's no longer unacceptable in my vehicle.

Good luck to you guys getting your issues resolved!

Re: Problem With 2014 Grand Cherokee Heater

I wrote Chrysler in December 2013 about this problem, and never got a reply. So today I called the customer service number 1-877-426-5337 and spoke with a representative. She looked into my records and noted that my letter had been received. I reaffirmed my problem and the need for a resolution. She said someone would be in touch. About a half hour later, someone indeed did call and said they would forward my concerns to the engineering department, and that all I could do was to wait until they issue a repair notice to the dealers. I am not sure what more I can do, but wait and see if they actually do this. My feeling after the call is that everyone should write a letter to Chrysler, or at least call them, and file a complaint about this problem. My gut feeling is, that when we go to the dealer and complain, that kind of complaining does not reach Chrysler. We need to let Chrysler know directly that there are many, many people having this problem.

The number is 1-877-426-5337. To write, the address is:

Customer Service
Chrysler Group LLC Customer Center
PO Box 21-8004
Auburn Hills, MI 48321-8004

Re: Problem With 2014 Grand Cherokee Heater

Had my car back to the dealer for the fifth time on 2/10/14. First time they replaced the AC module, this time they replaced the main control module and reloaded the software again. Unfortunatly they problem is still there. All they can tell me was that they need to discuss with Chrysler Engineering to see if they have any suggestions.

I had it in to the dealer to fix the check engine light and throttle control light issue (at 850 miles), and asked about the heater. They said it checked out normal, but after freezing on the drive back later, I took it back into the dealer and demonstrated it. They absolutely said there is an issue, and that they were going to talk to their Tech rep.

Thanks in advance.

I think that's all most of us can hope for. There's no manual mode in this system: the two options are "fully automatic" and "semi-automatic". I, for one, would be okay if an actual manual mode (aka. "heat throttle") were available. That is to say, I could tolerate a sub-par (or insane) automatic system if I could just set a heat throttle level and fan speed.

It would be interesting if there were a poll for those of us with the issue. Engine type or build date would be the most interesting data points (uncertain which would be more likely to correlate with problems). I'm a mid-December build Summit diesel, cruising around in 0 F weather with the thermostat set to LO (freezing is better than burning).

Re: Problem With 2014 Grand Cherokee Heater

I called Jeep customer care last week. They called me back about three days later to discuss the matter and they advised to take it back to the dealer again after speaking with the dealer.

Not sure how the lemon law works or if this would qualify but plan to look into it as I really cannot drive this thing in winter and be comfortable.

This time I am taking two temp gauges with. One for the vent itself and the other for the dash of the car. I tested it and it was blowing 84 when set at 60 and I could,not hold the temp gauge in front any longer as my hand was burning , so not sure how high it really went.

I tried it again bearing through the sauna with fan on 3. Once it hit a really warm temp(no gauge with me) then it starts blowing cold air from outside. Lmao. What a pos. I doubt this third trip to the dealer is going to any good use of my time. Last time the kid was sort of a smart ass to me telling me its a thermostat! Yes, for auto I would agree with that, but not a manual mode dumb dumb.

Hopefully they find a fix as this is my only issue right now.

For the vent temperature you might try a meat thermometer (they have a long stem). Similar thermometers are sold at AutoZone, etc, for use in AC system work. Stick one in the vent and you don't have to hold it... this helps if you want to take a picture to document the insanity.

There is no true manual mode on these trim levels—just fully automatic and semiautomatic modes. The thermostat is always engaged and in control. What people are calling "manual mode" is "the system allows you to control blower fan speed" mode. There is no way to directly control how much heat is pouring from the vents.

That may be, but last time I checked my house doesn't go from 50 to 90 when I have it set to 70!
