The lawsuit was filed this week in Northern California federal court. The plaintiff, David Rasmussen, who owns a 2014 Tesla Model S 85, has claimed that the range of his car was suddenly cut to as low as 64 kilometres.
Rasmussen has alleged that his car lost the equivalent of 8kWh of battery capacity. The plaintiff is reportedly seeking class action status for the owners of older Model S and Model X who have suffered from the same issues.
Moreover, Rasmussen has alleged that despite his attempt to repair the car under the warranty, Tesla claimed that the battery capacity degradation was normal.
According to Reuters, the problem with Model S and Model X batteries has been widely discussed by Tesla’s customers on online forums, including TeslaMotorsClub.com. Many of the owners claimed that the travel range they were used to has drastically declined following a recent software update, forcing them to recharge their cars more often.
Tesla responded by claiming that only a small number of older Model S and Model X cars was affected. As cited by Reuters, the company promised to address the issue by rolling out new updates that it was already working on.
Following the news of the lawsuit, Tesla’s stock saw a slight decline of 0.7%. At press time, the company’s shares were trading around $236.
