I am new to the forum and would appreciate anyone's/everyone's reaction to the following. I was just about to trade-in my 2011 GC Overland Summit Edition for the 2014 GC Summit with 5.7L at a dealer in or near Westchester, NY. I love the Hemi and need that new 8-speed tranny. After reading the absurdly long list of loyal jeep fans complaining about The Heater Issue, I am taking a pause on the trade-in to ask those who have gone before me whether I should a) wait to see if Jeep does a proper Recall and Repair for the afflicted vehicles, b) buy something else (but what would come close to a Hemi/8-speed, etc?), or c) take my chances and buy the 2014 and hope I don't get stuck with a bad one? If I do move forward with the trade-in, is there any sure-fire way to confirm that a particular vehicle is not infected with The Heater Issue? Is there a more comprehensive delivery checklist available for any other potential issues that I should follow? Thanks folks.

There is no definite, absolutely repeatable test. My vehicle has done it every time from the time it was delivered (except for one time it was "normal", a few days ago). Other vehicles vary.

Here's the best experimental design I can come up with: test on a cold day, obtain a digital oven thermometer (as in jeepwes' video), allow the Jeep to warm up, set the thermostat to 62 F, turn the blower speed to max, and watch the temperature measurement readout for the vent air temperature.

Vent air temp shouldn't exceed 105 F or so. If it gets to 120+ F then that's too damn hot (mine goes to 140+ F). Ideally, you would repeat this experiment on multiple occasions to reduce the odds you caught the vehicle on a "good day". As noted, you must wait until the engine has warmed up enough to be able to blow hot air, so it takes a few minutes before the cold-started vehicle begins to incinerate the passengers.

Testing for whether it will schizophrenically cycle between blowing very hot and very cold takes much longer because it is dependent on whether the thermostat believes the cabin needs to be reheated. You have to wait until the cabin temperature reaches the thermostat setting (again, there is no manual mode on these vehicles). If it happens, the temperature swing can be +/- 70 F in under a minute.

Re: Problem With 2014 Grand Cherokee Heater

Yeah so frustrated. I have never owned a car that blows such hot air and then switches back so quickly. Seems there is no middle ground on the heater.

The jeep case asked if I would be willing to try another dealer and said yes. Told him if you find a fox there are alot of people that would benefit. And if jeep is not trying to fix it, then they can have it back. Getting more frustrated as the drags on.

Re: Problem With 2014 Grand Cherokee Heater

Not much of an update, but I (finally) did hear back from a different Case Manager, after I wrote to the original Case Manager asking for a status on an engineer who was supposedly flying from Detroit to Denver to look at the car on 2/28.

Here is what the second Case Manager said:

(I am also having the problem of intermittent functioning of the remote door lock/unlock)

"I'm contacting you on behalf of your case manager, Edgar, regarding your 2014 JEEP GRAND CHEROKEE. New information has been provided to assist our engineers, and they are doing further research into the concern with the heater. Because of this, I will be escalating your case to another department, who will follow up with you, when new information is available to us. No definite time frame is available regarding when this information will be provided. However, Edgar will continue working with you in regards to the keyless entry concern, and will remain your point of contact while JEEP is working on a resolution for you. I apologize for the current situation, the time youve spent taking your vehicle back to the dealership and hope to have more information available soon!"

She gave no indication of what the other department she escalated this to, but I at least have a dealership that acknowledges that there is a problem. As more people report this to Chrysler Corporate (in addition to their dealers), this will gain more visibility. Like others, I can't wait to see how this functions in the summer.

Hey, that's much better than the dismissive responses many others have received. Hope it pans out.

Actually, I am concerned about that for perhaps a different reason than many others. From what we have heard from some reports, the vehicles are tolerable during warmer weather. That's a problem: if the system can't be made to demonstrate its insanity then the chances of having the problem identified diminish greatly.

That would leave a tight window for some of us to lemon out a vehicle with an intolerable HVAC system before being stuck with the vehicle.

Re: Problem With 2014 Grand Cherokee Heater

Update, no update really. Jeep rep emailed today. More delays/stall tactics, told me he would get back to me on Thursday. That is what he told me twice before. Great customer service!

NOOOO I turned in my 2011 and regret it every day. I had ZERO issues with ANY jeep i have ever owned until now. I HATE this new one... too bad, it could be awesome but NOTHING seems to work consistently!

its horrible... yes, nothing has broken down (for me at least) but it feels like they just stuck a bunch of mismatched non-tested gadgets in this thing and put it up for sale!

Re: Problem With 2014 Grand Cherokee Heater

I agree. Keep the 2011 until this issue is resolved. I wish I had my 2011 back. I had zero problems with it. Also, when I used remote start in cold weather, the defrost (front and rear) came on along with the seats, which I liked. Now, with the 2014, only the heater and seats come on, not front and rear defrost. This car is a disappointment in several ways.

Thanks for the feedback. For what it's worth, I bought my 2011 JGC Overland Summit Edition from an out of town dealer in NJ that I checked-in with today and was going to have a discussion with. He is supposed to call me back tomorrow. I want to get his 2 cents on the build quality and service record of the 2014 models. I am curious whether he comes clean on any issues that are reported in the forum. I'm not inclined to do the trade but, to be honest, the tranny on the 2011 is kind of mediocre and seems to be lurching a bit now (at 45k miles). If I don't do the 2014 JGC I will be looking for an alternative. Thoughts?

Re: Problem With 2014 Grand Cherokee Heater

I really don't know what to suggest. If I had to buy something other than a Jeep Grand Cherokee, I would be dissatisfied with whatever it would be, because to me the Jeep GC is the perfect overall design that suits me better than anything else. GM doesn't offer anything comparable, I don't like Explorers, and none of the imports hold any interest for me. The new Lincoln MKC coming out this summer looks interesting, but I don't know. I sure hope Chrysler/Jeep gets this problem resolved.

Re: Problem With 2014 Grand Cherokee Heater

I purchased my 2014 limited in June of 2013. I did not have this issue. I recently brought the Jeep in to have the TSB done for the remote start issue. This issue was that the heater shut off after the drivers side door opened, using remote start. Now after the TSB was done I have this heater issue, where it blows out incredibly hot air, and I have to keep turning down the setpoint. I never had to do this before the flash was done for the TSB. And to add misery to pain, after 2 days the heat is now shutting off when I open the drivers door just like it did to beging with. WTF???

Re: Problem With 2014 Grand Cherokee Heater

Very interesting. Def sounds like a bug to me. Jeep case worker told me to call this other dealer and they will help. I called them and they said sounds like it is working correctly, there is no real manual mode. Ok, so guess I need to go re-read the owners manual I have to see what it says about manual mode. At this rate ready for my third attempt and lemon this thing if it can be.

Update. According to the owners manual you can adjust the fan speed and direction of air. It mentions nothing of adjusting the temp. Argh! Who the hell designs a car with no option for manual override. Every other car I have owned has had a manual option. Leave it to American cars to do something so stupid. Guess we will see what the next appointment brings.
