I'm having the same issue for my 2017 Touring-L. The outside temperature gauge sometimes takes 8-10 minutes to update or it does not update at all. As suggested in this thread, I PM'd ChryslerCares with my VIN and the issue. I also already scheduled an appointment for the two recalls and will bring up the temperature gauge with them as well (but it doesn't sound like many on this thread had any luck with the dealerships on this issue).

On a somewhat related note (as far as time goes), does anyone know how to stop the vehicle from "Updating Address Book" for their phone every time you start the vehicle??? This annoying process takes five minutes every time I start the vehicle. During the update, I'm unable to verbally request a call be made to someone. This is irritating b/c I often want to call my spouse or someone that I'm on my way or whatever. I've learned I have to physically touch the console and thumb through Recent Calls to make the call or wait 5+ minutes until the update is finished.

Should have upgraded the 5" screen.

On my '18 the outside temp indicator is very light in color. Not bright white like the rest of the indications. Is this normal?

Outdoor temperature way off, AC won’t engage

We bought a 2018 Chrysler Pacific just over a month ago. This morning my husband ran to get food and the temperature read that it was 30 degrees outside. We are in the south and it doesn’t get lower than 70 degrees in the summer. Later this afternoon we tried to run errands with our small children and the temperature display dropped to as low as negative 16 degrees and our our AC would not engage and only blew very hot air. We tried turning the air off and on, changing from vent to floor and back, recycled and outside air and nothing worked. We have an appointment scheduled with the dealer in a few days. Has anyone experienced this before? I saw another post about the temp being off by a few degrees but this is a huge difference and is affecting our AC.

Welcome the forum.

The dealer will probably have to update the software or change a sensor. The ambient temperature sensor was replaced on my van since software updates didn't fix the problem I had with a stuck/delayed cooler temperature reading. It was winter at the time so it didn't affect the AC.

Some things you might try before you go to the dealer are:
Try changing the Units in the Uapps, Settings, touchscreen display to Celsius and then back to Fahrenheit.
If you have the climate on Auto settings, try the manual settings and set the temperature to all the way hot (84) and then all the way cold. Probably won't change anything, but at least you've tried to do something.

When my back up sensors don't seem to be working as well as I think they should I go through the car wash and they seem to improve. The van doesn't get that dirty, but there is a lot of dust here. The ambient temperature sensor is toward the front of the van, so maybe check to see if any leaves or debris could have come in somewhere near the windshield or engine.

I hope someone has some better suggestions.

If you put your van info (year, trim, gas/hybrid, etc.) in the signature line of the UserCP it might help others assist you.

It could be pack rats. A couple of years ago, I had a Mini that pack rats loved, especially the wiring to the ambient air sensor. They got the Mini twice, then I installed an ultrasonic device to keep them away and the car was fine.

Outside Temperature sensor reading below actual reading

I have a 2017 Pacifica Limited, and noticed that in some hot days the temperature reading can be up to 20 F below actual. It will sometimes take 5-7 minutes for the temperature to start updating but sometimes it doesn't at all. I also feel how the A/C is not cooling right from the start. I have several cars, so I know what is the normal cooling time when car is parked outside in the sun, but the Pacifica is just not right. I already bring to dealer and couldn't find anything wrong. I have been 3 different times, and since it is an intermittent issue the service tech just can find nothing wrong.

There is a Star Case #1608000133 for ambient air temperature issues. The ambient air temperature sensor was replaced in my van. Of course, I shouldn't be the one telling you this, but you can give the info to your service department if they can't find it.
I probably found the info in the forum to give to my service department.

@irpilot Maybe the threads should be merged?

They replaced the ambient sensors(in and out) with no luck. Turns out there was a harness running along the grill that was allowing air/water to get forced into it causing sensor issues. They replaced and rerouted it and it has been fixed for now.
