exterior temp reading inaccurate

[iadslgladiator]

anybody else notice their exterior air temp reading incorrectly?

i've had it happen twice now.......i remote start my jeep and when i get it the exterior temp reading is at least 25 degrees off.

first time it happened.....a couple days ago in the afternoon around 2 p.m. actual outside air temp was 25 degrees. i had remote started my jeep from the office (ran for approx 5 minutes) and when i got it the the seat and steering wheel heaters weren't on and the blower wasn't blowing on high speed. i noticed the exterior temp display said 53 degrees. after i started driving the temp reading changed to the correct air temp of 25 degree. didn't think much about it.....figured it had something to do with the sun actually shinning that day and warming the sensor (where ever it is) or some other abnormal thing.

this morning 7 a.m., i remote started my car from the house, again had been running about 5 minutes when i got in it. outside air temp was actually about 18 degrees, neither the seat or steering wheel heaters were on and blower was not blowing high speed. interior was still ice cold and windows had barely begun to defrost. sun was barely up so there was no way the outside air temp sensor could have been manipulated by it. again after driving down the road a little ways it started reading correctly but obviously by then i'm already in a cold car driving down the road which defeats the purpose.

obviously not a dire problem, just frustrating being that its a 65k vehicle. it should be able to read air temp correctly and initiate the correct warming functions/sequence.

i rarely have good experiences at the dealer so i have no desire to have them try to trouble shoot it. wondering if any of you have noticed similar and if so, did you figure out what was causing it or was it something the dealer was able to easily diagnose and remedy?

I've noticed the same thing. For me, when I remote start the truck in the morning in the garage (with the garage door open of course), the heated seats and steering wheel don't come on, and the temp reads 41 degrees. As soon as I pull out onto the road, it drops down to an accurate reading. It's not a heated garage or anything.

I wonder if the heat from the engine running throws off the sensor when the truck is sitting still.

I take it the seats and steering wheel heaters have worked for you at some point with a remote start? Like they are enabled?

is it reading incorrectly when you are driving?

Mine will also do this heat and miss. It’s not picking up engine warmth because it’s been outside, overnight. Mine won’t fit in my garage...

There are multiple other threads on this - some find that it's keeping a temp from the day before and once started, it adjusts accordingly - like mine - if it's 50 yesterday when I drove it and shut it off, and it's 35 now, it will show 50 until I start it and watch the temp slowly drop and it's then accurate.

Others seem to be seeing something else.

There are at least 2, perhaps 3, other threads dating back to last winter on it so yes, others have seen this.

The only frustration for me is how our temps here swing wildly so if I last drove it when it was 45 or so out and then the temp drops to 35 and I do a remote start, the heated seats and wheel won't be triggered. Next start later that day it will be fine.

It is not engine temp throwing it off. It just did it to me again exterior temp reading 43 degrees, no heaters/warmers on when I got in it. Drove down road and temp changed to 28 degrees.

Seems to read correctly while driving

Same on my end

So who's taken it to the dealership and had it looked it? Or are we hoping it'll fix itself.

That's sort of funny because as I mentioned, this is not the first thread on this topic. I know it's been mentioned at least 2 or 3 other times, this could be the 4th, with multiple "Me, TOO!"s in there - and yet, I've seen nothing other than group "me, too"s.
Sort of like once I hear someone else has the problem, I feel better and won't do anything about it.

I'm curious - not that I see mine as a real problem - but for those who do see it that way or have a bigger issue with it - has anyone gone to a dealership to address it under WARRANTY?

Hi Andrew, try this. When you get home in the evening make a note of the temperature reading. The next morning check it again. It may be retaining the previous reading. I'll check my JL if I can remember to do so.

Later,
Johnny

Sounds like it is only an issue with the first start of the day, then it acts correct.y. I’ve noticed the same when I start it in the garage, but thought it was just warmer in the garage than outside. I don’t think I had this problem when it was new so wonder if there was an update that broke this feature.

I know mine is not retaining the temp from the last shut down. It hasn't been over 30 degrees for several days and the last 3 or more times it done this the temp has read between 42 and 53 degrees. Its not just on the morning starts either. The first time it did it was an afternoon start about 2 pm. It did it again today when I left work around 5.

Your engine is warming the ambient air directly around the sensor as it sits. Once you start moving and get it fresh air it adjusts.

I'm surprised nobody has even heard of a solution as it is seems to be relatively common. I really feel like a bitch complaining about these upscale ammenities in a jeep but like I said, for a 65k vehicle i expect shit to work right......
Ill probably call the dealer and see what they say. I have no intention of letting them have it for several days to screw with it. But if they claim to "know" ill probably let em take a crack at it.
