I get the same thing - always showing in the 70's with it near 100 out. My wrangler is always spot on.

Re: Outside Temperature Sensor Problem

I would love to read Chryslers logic as to why they designed the outside air temp reading to operate this way and not change as the temp changes.

Re: Outside Temperature Sensor Problem

I checked mine today. It said 77 when I started it up in the garage. By the time I left my development, about a half mile, it read 84.

This was 3 degrees lower than the local school was showing, and 3 degrees higher than Town Hall. Since I normally turn the screen off (the default on the MDX) that's close enough for me. When I need an accurate reading I open the window and stick my hand out.

On my 01 Pathfinder haven't had this type of an issue. The reading was spot on most of the time and was much faster to update. Seems like a step backwards for Jeep.
I went on another trip today this time longer. After couple of minutes on hway temp strated to creep up 79, 82, 85,89, 92, 95. The valid temp should have been 90F+. I don't care about plus minus couple of F but 80F is not even remotly in the ballpark. If the senor is crap and needs like 30 minutes to show correct info than show N/A instead of some temp which is vastly disconnected from reality.

As Milous has noted, this is being changed.

Re: Outside Temperature Sensor Problem

I just took delivery of my 2014 GC Limited last week and noticed this was an issue-almost instantly. This is simple technology that should operate and function properly within +/- a degree or two. Mine is consistently 8-10 off and occasionally reads 12 degrees lower than the actual outside temperature. Shame on Jeep. This is simple, basic technology that should not need to wait until q4 for a fix. Another 90 days to find the right part, notify owners, and have communicated to them the fix? This is a know Jeep issue going back to 2011. This is mind blowing to me. I've already had it to the dealer-they replaced the sensor-with another one that doesn't work.

Re: Outside Temperature Sensor Problem

My brand new JGC Overland, 5.7Hemi, 4x4 and Quad Lift only has 750 miles on it, and I am experiencing the same problem. Here in Austin it has been above 100 (Faren) for the last several days and the outside reading never goes anything above 7 degrees lower than reality. If it's 98 out, the temp sensor shows 91...etc for all other readings...7 degrees low. Not sure why we are experiencing this, since my 2001 JGC was within one degree (F) of real outside temp. Rather annoying. Is there are dealer fix?

Fix is coming. Not available yet. I believe it is entirely programming though not sensor based problem

Think the fix will be able to be done through owner Uconnect update or will a visit to a dealer be required for their wiTech hookup?

Good to hear...I hope the fix is available before Winter.

As it stands now, I don't even waste my time looking at my Jeeps temp display.

Re: Outside Temperature Sensor Problem

TMK it is WiTech programming... However there have been unconfirmed reports of some fixes that happened over the air that I did not think was possible.

This is interesting - the outside air temp sensor on my 2014 Grand Cherokee Limited seems to be malfunctioning. This thread has observed high temps. Mine is fixed low and eventually eases up after 10 minutes or more. Example. Today, it insisted that it was 42 degrees out. It was 26 degrees warmer (68). The other day it was fixed on 39 when I drove it two times during the day - it was 58 out. We've had several cars and I've never had one where the car didn't just display the outside temp right off and right where you'd expect it to be (i.e. the actual outside temperature). This isn't a complicated bit, so I'm surprised to have the issues and see these posts. Is Jeep using a poor quality part or are these too hot / too cold stories the odd exceptions? I'll be taking it in for its first service visit to get the problem resolved.

My outside air temp is erratic too. On start-up it is usually at the temperature it was when it was last driven...then it will take 4-8 minutes to start reacting to the real outside temperature. For example, start -up in the morning it reads around 75 degrees ( I live in sunny Ca), then in about 4-8 minutes it comes down to am temps of about 60 degrees or less. If parked on a hot day, say 100 degrees, and left overnight it will still read very high on start-up and then finally reach the corrected temp. If hitting the freeway right away, it will correct itself much more quickly...but in town driving with a lot of stops it takes way too long. Service writer says it can take as long as 20 minutes!!! says that it is taking a lot of readings and that it is looking for an average and that is why it needs so much time???...of course we know that is not right.. My 11 year old Duramax oat has always been perfectly correct on start -up and changes immediately with the temperature...as you would expect it to. Just another problem with the GC that will take some time to fix.

Love this forum and all the help all you have been on other posts. I like this jeep a lot but hope the electronic problems, transmission issues, uconnect issues, temperature and climate issues can be resolved. I really like the off road capability it has...the hill descent control is great as is the low 4-wheel drive in the "Rock" setting.

Sorry for the rambling on so..
