Tesla Model S & Model X Software Update Battery Drain

WHAT’S THE ISSUE?

Hagens Berman has filed a lawsuit on behalf of owners and lessors of Tesla Model S and Model X vehicles, alleging that Tesla's automatic software updates are responsible for a drastic drop in battery performance and driving range in affected vehicles. In some cases, attorneys allege, the software update renders batteries fully inoperable, and drivers are told they must purchase a new $15,000 battery.

• Tesla Model S
• Tesla Model X

TESLA AUTOMATIC SOFTWARE UPDATES EXPLAINED

Tesla routinely performs automatic software updates on its vehicles. Typically, if an automaker wants to update vehicle software, the automaker will notify drivers, and include a brief description of and reason for the update. This gives customers the opportunity to choose to receive the update, and ask questions about potential downsides or effects.

Because Tesla owners connect directly to the automaker via Wi-Fi, Tesla can push its software updates onto its customers at any time without their consent or the opportunity to ask questions.

ABOUT MODEL S & MODEL X DIMINISHED BATTERY PERFORMANCE

Attorneys say that Tesla markets its vehicles with the promise of a battery “designed to function for the entire life of the vehicle,” but following software updates, Model S and Model X drivers reportedly experience drastic drops in battery performance, resulting in a decrease in vehicle driving range of up to 20%. In some cases, software updates render Tesla batteries inoperable, and drivers are told to purchase a new battery at $15,000+ apiece. 

At no point has Tesla warned customers that its software update would derate the battery or result in the depletion of battery life, and drivers are told they have recourse if they encounter performance issues following a software update. Updates cannot be canceled once they begin, and Tesla tells consumers it is not possible to revert to previous versions of the vehicle software.

WHAT TESLA KNEW ABOUT SOFTWARE UPDATES & BATTERY PERFORMANCE

In prior litigation, Tesla has not challenged claims that its software updates can and do lead to diminished battery performance, and admitted that data showed a May 2019 software update caused a 10% decrease in battery performance in 2012-2016 Model S vehicles. In a separate lawsuit that was settled in 2021, Tesla agreed to pay $1.5 million to settle claims that its May 2019 software update temporarily cut the maximum charge of some of its vehicles, and a court in Norway ordered Tesla to pay $16,000 each to 30 plaintiffs who experienced a drop in battery performance and charging speed following that same 2019 software update.

WHAT TESLA OWNERS ARE SAYING

Tesla owners have taken to online forums to share stories of reduced battery performance following software updates::

• “So far the battery capacity decreases every time I drive.”
• “How do they explain the sudden loss of range. Gradual reduction in range is or can be normal but I don’t know how they can say a sudden drop-off-the-cliff in range is normal or gradual.”
• “This whole thing follows the Tesla mode of operation: throw out a fix and deal with the consequences later.”
• “Any range loss that is due to a software change and not due to degradation is theft even if they never advertised explicit battery…capacity.”
• “I’m already fine with never getting another update and don’t want one with the fiasco that v9 has been…I’ve removed all saved wifi Aps and turned wifi off hoping that I’ll never get an update.”

YOUR RIGHTS AS A VEHICLE OWNER

Attorneys believe that Tesla’s automatic updates may violate the Computer Fraud and Abuse Act and state consumer protection laws, and we find it unacceptable for Tesla to impose automatic updates that decreases vehicle performance suddenly and without warning. We believe Tesla needs to be held accountable to its customers who have the right to replacement costs of vehicle parts. Model S and Model X owners and lessors deserve a real answer from Tesla about the link between automatic software updates and battery performance, as well as peace of mind about their vehicle performance.

HOW CAN A CLASS-ACTION LAWSUIT HELP?

Through a class-action lawsuit, individual consumers can collectively bring claims against large corporations that would otherwise have the upper hand, like Tesla. A class-action lawsuit seeks to level the playing field, bringing strength to collective action to change corrupt practices and negligent responses to customers. Though these measures do not bring immediate relief, they are a time-tested method of holding companies accountable for wrongdoing, including automakers’ failure to sell reliable vehicles to their customers.
