2016 ES300h, 31k miles....recently noticed the outdoor temp display in dash was not accurate, especially for the first 30 minutes or so after startup. After that, the reading gradually normalizes. I am guessing that this temp reading controls the climate system, so it may be more than an annoyance. I have a dealer/warranty appointment tomorrow, but suspect they may not be able to duplicate the malfunction, since I will be driving more than 30 minutes to get there, and it will probably be ok by then. Anyway, at least I will have documented the complaint before warranty expires on Aug. 1st. Has anyone else had this problem?

 

How innacurate? It is normal for the sensor to read ~10F higher if parked in sunlight, especially on black asphalt. If then drops once you start driving as the sensor cools down by incoming airflow.
