Another useless piece of electronics to go with the rest of the infotainment system. Really, pathetic.It's completely inaccurate no matter how much time is spent driving. My Android Auto home screen shows weather and the car can read as high as 8 Celsius (14 F) higher
Hi TomMac,My 2018 Stelvio outside temp is worthless. Took it to the dealer last Wednesday.....the sensor is in the right outside rear view mirror. They did the troubleshooting working with AR Star Service. Mirror has to to replaced. Still at the dealer waiting for the mirror assembly to come in. Will post if and when I get my car back as to resolution.
Every car I've owned in the past has been fairly accurate once I've been driving for 10 minutes or so and the sensor has a chance to stabilize and read the ambient air temp. My Stelvio, even after driving for a long period of time is nowhere near the actual temp. Example: I was on a 3hr road trip, cruising speed of 85mph, and the temp gauge said it was 98 degrees F, actual temp was 82. I've done this same road trip with other vehicles and none have been that far off. At the end of the day it doesn't really matter because it doesn't really affect anything but it's just silly they couldn't put a little more effort into getting it more accurate. I guess just chalk it up as another weird oddity about this vehicle.Does anyone really expect a simple thermometer on the underside of the passenger side mirror on a car to be consistently accurate? I sure don't. My car is in and out of the sun/shade at varying speeds and other changing heat environments.
No offense, but how do you know it was actually 82 degrees? Just like how did ViscontiVerde 164L know that his last several cars have been accurate within a degree :wink. On previous trips was the weather exactly the same, same amount of sun, etc. Were the sensors in the same location on the cars?Every car I've owned in the past has been fairly accurate once I've been driving for 10 minutes or so and the sensor has a chance to stabilize and read the ambient air temp.

Look, I don't care about all the technical details of how it does or doesn't work. The fact of the matter is I've done this same road trip once or twice a month for the past 9 years. I'm in SoCal. The weather couldn't be anymore consistent. I can check the weather at a local weather station and compare to my vehicle. All my past vehicles it was always within a couple of degrees F from the local stations (and as I mentioned before this is assuming I've been moving around for a bit). The Stelvio was 15 degrees off. Please explain how other manufactures can get it pretty accurate but AR can't?No offense, but how do you know it was actually 82 degrees?

Here are some facts. It is actually a thermistor and not a thermometer in your car. The thermistors are actually quite inexpensive and accurate. However, our problem is that a car is a difficult environment for a temperature sensor. Many cars have the sensors near the front bumper and the engine, heat sources. These are also too close to many times a very hot roadway. Placing the sensor in the side mirror like AR is actually better than near the engine. British Rover brand sedans used to have an Ice-Alert safety sensing system near the front bumper which would warn the driver as the temp on the road neared freezing, but that was its singular safety purpose. There are no good locations on a car for a temp sensing thermsitor for consistent every day consistent use. They are all too close to the engine, concrete or asphalt road, glass, tires, direct sun exposure, etc. Note that most weather stations also have thermistors but locate them in ideal places away from buildings, trees, etc. and they place them fairly high above grass or soil and they are sun/solar shielded, etc. A temperature sensor on top of a hot building is a poor location. The temperature bank signs above hot asphalt parking lots usually read inaccurately high.
The times that your car temp sensors will be most accurate are in cloudy weather or at night. I still would not consider any of them to be very accurate. Just a sometimes fun feature, but don't bet your life on them. If you want to check the general accuracy of your Stelvio or Giulia temp sensor wait until it is in your garage or enclosed building like a parking lot for some time and compare the reading to a fairly accurate thermometer you might have that you place for a test comparison on or near the mirror. I'll pick a thermistor sensor in my passenger mirror any day over one behind the front bumper! I'll take both of them with a huge grain of salt.
Here's what a supposed expert says. There are many of these. I'll only bore you with one. :smile

It's obvious that you really don't care about the technical details of how it does or doesn't work (of course they are all nonsense anyway, I was just making it all up) so I won't explain. I wasn't offended. My round table meter is registering 82. Sounds about right.Look, I don't care about all the technical details of how it does or doesn't work.

Please explain how other manufactures can get it pretty accurate but AR can't? Actually don't explain because I don't really care. I know what I've experienced.
