While the A/C is on, The Jeep randomly blows HOT air from the floor vents for 3-5 mins then stops

[Mjclay]

We just took my JLU sport to Indiana for my brothers wedding and definitely noticed this happening. The weird thing is we were on the highway and the air was on (no auto). It was set to low and fan was at 4.

This needs to be addressed by the maker, I am hearing more and more comment on this

So i have noticed that my JLRU will blow hot air (90 degree or so) even though i have the AC set to LOW.
Its coming from the vents in the footwells even if i have it selected to blow only out of the top vents.

Anyone else notice this or have the same problem

I have noticed this too. I thought it was just me imagining things, but on several occasions I have noticed warm air out of the foot well when it’s hot outside and th AC should be cooling.

Here is my experience at the dealer and some info straight from FCA via the dealer.

I have the problem you are all describing. It will be blowing nice cold air and then POOF a blast of hot humid air will blow in on the floor for a very brief moment. While at dealer I mentioned it and they said there is an A/C software update but they don't know what the update exactly does, they just know there is an update. So they do the update and within the hour FCA is on the phone with the servivce manager because he saw my complaint and software update hit their system. He asked him what am I experiencing so the service manager told him and the FCA rep said the following...
"Owners are experiencing lack of cooling or bursts of hot humid air. Check the lower left corner of the condenser for leaks if A/C is not blowing cold enough (they have some leaking units). For the bursts of hot air explain to the customer that if you are driving for long periods of time with the recirc button on the computer will open the damper and allow a burst of outside fresh air in so that oxygen levels will not get low" NO I'm not making this up!
He also said that this occurs while it is on MAX A/C only but I told that service manager that's not true.

The service manager was kind of chuckling and says that this falls under "normal" because the Jeep was designed that way. I told him I have tried to replicate it by opening the recirc damper and can't get the same effect which leads me to believe there may be another port which allows this air in. When I simply hit the recirc button to go to fresh air the A/C easily handles the humid air from outside and chills it. If there is some other damper we don't know about that allows straight up hot air in directly from the outside that would explain it.
So... it is normal BUT maybe this software will do something. The longer you drive the more likely it will happen because the computer reads the recirc closed longer. I'll see if it resolves the issue and post back.

My wife said the same guy who designed the A/C to work like this was probably the one to have auto stop/start set to on

@ JeepCares you are correct that people need to report this. This is on FCA's radar and they are aware of the issue. The more reports the more likely to keep progress on it.

Same here on a 200mi trip.

@mgroeger i love your detailed response and it kinda makes sense but I hate the fact that FCA is watching over us like Big Brother and then tell the service folks to spin us a bedtime story, I feel like I am in the land of Oz and told not to pay attention to the man behind the curtain which is FCA

I hear ya man. Even the service manager was shocked at getting that call. Kind of creepy, but until I can afford my '67 or '72 Stingray everything is going the way of the computer.
To others on this post regarding how they have their A/C set... it appears that it does not matter what the settings are other than it being on recirc. If someone wants to drive with no recirc and see if it still does this please let us know.
Around town we need the recirc on, I'm taking a trip in a few weeks and will test it with no recirc.
