Tesla Model 3 and Model Y owners complain about heat pump failures at low temperatures

During the winter time, the heating function of cars is essential for safely driving a vehicle with reasonable interior temperatures as well as clear windows that do not fog up. However, disgruntled Tesla Model 3 and Model Y owners have once again reported that the heating function of their EVs stopped working in low temperatures due to a defective heat pump. Most of these complaints seem to originate from northern US states as well as from Canada, which has been hit by a cold front that caused extreme temperatures of -20 degrees Fahrenheit or colder.

It is well known that heat pumps cannot work efficiently at such low temperatures, but a complete failure of a car’s heating system could lead to life-threatening situations in the worst case. The California-based automaker asserts that these Model 3 and Model Y heat pump issues can be resolved with a rather simple software update, but a Tesla owner from Toronto has allegedly received a horrendous repair bill for this exact defect in his electric SUV. In his case, the AC compressor and a manifold had to be replaced, which apparently would have cost a total of CA$5,000 had it happened after the warranty expired.

Even though not too many regions around the world suffer from such extremely cold winter temperatures, these reports still suggest that driving an electric car in the depths of winter can result in various issues and disadvantages. But while these repairable Tesla Model 3 and Model Y heat pump failures are certainly a nuisance, it has to be noted that cars with traditional internal combustion engines may also struggle in severely low temperatures.
