The lawsuit alleging Tesla used a software update to throttle charging speed and maximum battery voltage on some Model S cars is over. And Tesla has agreed to pay up.
The offending update was released back in 2019 and affected roughly 1,743 vehicles, according to plaintiffs. And Tesla has now agreed to pay the owner of each affected vehicle $625 as part of a proposed settlement (via Reuters)

Certain Tesla Model S cars experience drops in range of around 12 to 30 miles following the 2019.16.2 software update, which also reduced the speed of DC rapid charging at Tesla's Supercharger stations.
At the time, Tesla told Elektrek that the update was designed to “protect the battery and improve longevity” and that it only affected “a small percentage of owners”.
However, those owners weren’t happy, and the result was that Tesla has been sued in multiple territories in an attempt to get compensation. One lawsuit in Norway led to the company being ordered to pay 136,000 kroner ($16,000) to thousands of affected customers. Tesla is appealing that decision.
In the U.S. it appears everything is all sorted out, and the final result involves a $1.5 million settlement. That includes the compensation for affected users and $410,000 in the plaintiffs’ legal fees and costs.
The owners’ lawyers did their own investigation and claimed that “voltage limitation was temporary, with a 10% reduction lasting about 3 months, and a smaller 7% reduction lasting another 7 months before the corrective update was released in March 2020. Following that second update, the vehicles’ voltage showed steady restoration over time.”
Tesla’s own data claims that 1,552 vehicles had their maximum battery voltage restored, while 57 vehicles had battery replacements. Other vehicles should see their maximum voltage restored over time, according to the court documents.
This settlement is “many times the prorated value of the temporarily reduced maximum voltage, and thus represents an excellent and efficient result for the Settlement Class”, according to court documents. It's not entirely clear how plaintiffs will receive their money, though a U.S. district court judge is set to convene a hearing on the proposed settlement on December 9.
While that’s still a way off, this hopefully means Tesla will think twice before trying this sort of thing again. Or, at the very least, it will give drivers who might be affected plenty of warning and explanation as to why.
