Tesla will have to pay $16,000 to each of the thousands of affected owners in the country. The fine could be even larger as other similar lawsuits are ongoing in other countries.
In 2019, Electrek published an article due to various reports from some Tesla owners that they saw significant drops in range from 12 to 30 miles after a software update.

Only the Model S and Model X vehicles with 85 kWh batteries, which were discontinued in 2016, appear to have been affected.
For most owners, the range drop occurred after updating to Tesla software updates 2019.16.1 and .2.
The owner of a Tesla vehicle, David Rasmussen, was among those affected and had one of the most severe range drops we have seen.
In addition to the loss of range, the DC fast charging rate at Supercharger. Affected owners are seeing much slower charging times.
When Electrek reported the issue, Tesla stated that the goal of the update is to "protect the battery and improve battery life" and only resulted in a loss of range for a "small percentage of owners.".
This created a lot of confusion among owners affected by the update, who wanted more details about the sudden need to "protect" the battery.
This led to a series of lawsuits in different markets for Tesla to compensate affected owners.

One of these lawsuits was filed in Norway, and the court has issued its ruling – finding that Tesla did indeed drop charging speeds with the update.
According to the Norwegian Nettavisen, Tesla did not respond to the lawsuit and the 30 owners behind the case were automatically given 136,000 kroner each in compensation.
