However, the battery warranty periods differ slightly depending on the model. For the Model S and X, the coverage period is eight years or 150,000 miles, whichever comes first. The Model Y and Model 3 Long Range and Performance have a battery warranty of eight years or 120,000, and finally, the Model 3 Rear Wheel drive is covered for eight years or 100,000. While eight years might sound impressive, this isn’t Tesla’s doing – the eight-year coverage is mandated by the federal government, and several OEMs extend the period to 10 years.
The company believes its cars are capable of lasting much longer than this, though, with many pointing to a post on X by Elon Musk in 2019. Then he said, “Current battery modules should last 300k to 500k miles (1,500 cycles),” with a complete cycle being a complete discharge and recharge of the battery. If we’re to believe these numbers, and with the improvements since then, the company probably thinks the first, second, or even third owners shouldn’t have to worry too much about the batteries.
