OUTSIDE Temperature Display is always 10degrees hotter than true outside temperature.

Has anyone else had this issue with their 2025 Rebel? Or any other vehicle?

I have noticed this as well, seems to always read higher than what my phone is saying.

I thought it was just me, so glad to know I'm not the only one seeing this discrepancy. I only just took possession of my 2025 Rebel GT and so far (aside from no hemi) this is the only noticeable thing. I traded in my 2015 Laramie and dang so many tech changes in 10 years, I'm sure there's more to discover

I’m not sure where the sensor is on my truck. The one on my Jeep is right by the radiator. So, if it’s anywhere near the engine compartment, that will greatly effect its accuracy.

Mine always reads high when I first start it, if it's a hot day. That's because the sensor is inside the driver outside mirror, and mine is black. After a few minutes driving it settles down and reads correct. Or not, Sometimes it never updates from when the truck was shut off. And then after a restart or two, it cures itself.

This problem is not unique to RAM. It was a common complaint when I wrenched on Toyotas. The dash value is calculated on them, based on the sensor (in front of radiator) and the solar load and who knows what else. I imagine Ram is similar. The Toyota owners' manuals even said it may take up to 4 minutes to read properly. That's the part we'd print and leave for the customer. Of course, we all know how deficient the owner's manual on our trucks is.

My Rebel is a '22. Outside temp reads high for 15 to 20 minutes of driving. After that long, it seems to drop to about what seems like the real temp.

The temp on my phone apps is from some nearby airport or other weather station, at least 6 feet off the ground, in the shade. Not going to read that low in the truck as I'm basically on the ground in the sun, like in a grocery store parking lot.
