Longtime Tesla owner, enthusiast, and EV evangelist Bjorn Nyland has discovered that his previous generation Tesla Model 3 (before 2021) has been plagued with an over-heated footwell issue. The footwell temperature elevates up to 50 ℃ (122 ℉ ) as the HVAC system tries to warm up the car interior during a drive or pre-conditioning the cabin before taking the car for a drive in cold weather.
Bjorn checked both the 2021 Tesla Model 3 and the slightly older Model 3 which can be called the previous generation or pre-design-refresh versions (2017 – 2020).
When Bjorn scanned the temperature of the pre-conditioned cabin of the 2021 Model 3 with a thermal imaging camera, 31.7 ℃ (89 ℉ ) was the max and ~28 ℃ (82.4 ℉ ) was the average temperature at the footwell area.
With the older version of the Tesla Model 3 he owns, the temperature of the footwell reached as high as 50 ℃ (122 ℉ ) — this is too hot for the feet. He did this test when the outside temperature was -11 ℃ (12.2 ℉ ), so manually stopping the footwell air blower would make the area too cold during the drive.
According to Bjorn, several other Model 3 owners of the previous generation are facing this issue. Several owners on Reddit and YouTube have confirmed that they are having the extremely hot Model 3 footwell issue.
Bjorn also knows about an owner who went to a Tesla Service Center and he was able to get this issue fixed. According to that owner, the Tesla Service team changed the faulty temperature sensor that is located under the center touchscreen (see image above).
Tesla should be able to fix the temperature sensors with its Mobile Service rangers or fix the cars with short turnaround time at the service centers, shouldn’t be a big deal installing new and better temperature sensors.
During the Q4 2020 Earnings Call, Tesla President of Automotive Jerome Guillen said that the electric car maker is working hard on improving the after-sales service. This year, the service appointment time will be further reduced and the overall customer experience will be enhanced, he emphasized.
