exterior temp reading inaccurate

[iadslgladiator]

I talked to the dealer and they basically just apologized. They know it's a problem but have no fix.

Im running into the same problem 2021 high altitude gladiator got off work remote started the Jeep for 10 mins went out to the Jeep and the heated seats and steering wheel wasn’t on. Temp was 33 but the Jeep was saying 46 until I drove down the road for 2 miles then it corrected itself. Has anyone actually went to the dealership? I’m going in this week

Did you set this feature to come on with remote starts or all starts in the U Connect settings??
Just saying, before you go to the dealership and possibly embarrass yourself.?
Let us know.

Which problem are you referring to?
Inaccurate temp reading or lack of heated seats and wheel at startup?
Who did you talk to?
Sales, service writer, tech?
Most known problems have TSBs.
Or just turn out to be operator error on setup.

Service manager. Temp reading incorrect, which causes the other things to not automatically come on.......the sensor is designed to work/ be accurate while the vehicle is in motion. they designed a function to work off a sensor that is only meant to be accurate when the vehicle is in motion when the function is only applicable while the vehicle is stationary.

News to me, I thought it was controlled by the settings in U Connect, but I suppose that is temp reliant, don’t really want them coming on when it’s 90 out.?
Sounds like there should be a software update for this?

I’ll ask the boss to check this out when she goes back to work tomorrow, because that’s shitty. Especially with winter weather here now.

Umm... really guys?

EVERY vehicle I've ever owned including multiple Jeep and Ram products has been intentionally programmed to work this way.

The ambient temp sensor is located just inside the grille. This is the best place to put it because it's shaded from direct UV which would give erroneous readings, and it's free from engine heat while driving because it's upstream. However, if you are stopped and the engine is hot, THEN the ambient sensor could potentially be detecting some warmth from the radiator which is why it's only accurate while driving down the road. 100% normal and intentional operation.

On the first cold start of the day, the ambient reading may be accurate immediately because the engine has cooled off. But if you've been driving and the engine is warm, starting the engine will result in higher than accurate readings initially until you start driving.

This isn't rocket science. And there's nothing a dealer will do about it because there's nothing a dealer CAN do about it.

But, the issue as some have mentioned is an overnight cold start is reading an incorrect ambient temperature in comparison to actual and not activating the seat and wheel heat when it should. Then only after driving does the correct ambient temperature display.
Weird.

This is a known thing. Not REAL common, but I've seen it.
The inaccurate temp reading leads to the heated seats not being on. I've seen it - but generally mine isn't that far off.
There's no TSB for this. People have made comments about this happening for 2 years.

My issue the last few days is that it may be 35 outside but 41 in my garage........... it's a non-attached uninsulated unheated garage but still, any closed area can be a few degrees warmer than the outside.
When I had it parked outside is when I noticed that it might read 45 when it was really 30. At times it had the last temperature from when it was driven the day before. My wife has seen it on her Grand Cherokee once if I recall correctly.

This isn't operator error - he'd know that because it would NEVER turn the heated seats on even when the temp did read correctly - he'd know better than that.

Naw, mine normally works fine. We did shopping yesterday - several stops. Each time I came back out and started it the seat heat was on.
Mine normally works perfectly fine. Only on occasion has it been wrong and it's the FIRST START OF THE DAY, never any problem with several trips in one day.

If mine misbehaves, it's the FIRST start.
35 out, drive to town (30 minutes) park, shop, come back out, start the truck - heated seats are on. Drive 10 minutes to bank, come back out, start truck - heated seats are on.
But tomorrow AM if I started it, it might have a wrong temp reading.
Sorry, but mine has never fit your "subsequent starts" scenario.

In short - if mine has a wrong reading, which it has on occasion, it's the FIRST start.
Once I've been driving it - it's always correct, always spot-on..

That's what's weird - the vehicle is warmed up, engine hot from a long drive - and that's when the heated seats and wheel always work!

Haha I sure did it’s on all starts I checked that first thing haha it’s in the shop right now I will let everyone know. It will be with them for alittle they are doing a lift and tires and some paint fix so when I find out I will update

Shouldn't it be on remote start ?

He said it was "on" all starts - that means you in the truck pushing the button on the dash or you in the house pushing the button on the fob or using your phone to start it.
You can turn that feature off, on for remote starts only, or on for all starts.

 

[s alex]

I set mine on remote start, and all the heating functions work as they should when I command start it. On "all starts" sometimes they were, sometimes they weren't.

 

[Idok]

Uh, really? Bashing a guy for asking? And this DOES impact other functions. You try getting your ass out into a 18 degree vehicle where the heated seats and wheel won't work as intended because the temp reading is off. You pay for those features - and they won't work when the damn thing says it's 45 out and it's really in the teens. You do a remote start expecting the seats and wheel to be a bit warmed up. The rear window and mirror defrost won't even work when it acts like his is doing.
This is the sort of response that keeps others from even asking questions - being told their issues aren't important.
So you come just to mock?
Maybe your HVAC will stop working and features you paid for will stop working so you can experience some frustration.
Good god, why can't people just try to help or answer instead of making people feel like idiots for even asking?

Amen brother!
