Tesla's warranty covers the Long Range and Performance battery for 8 years or 120,000 miles, whichever comes first, with at least 70% retention of battery capacity. Standard Range cars are covered for 100,000 miles.

OEM warranty

Low

The displayed range can fall without a matching loss of battery capacity. Tesla's warranty calls range estimates "an imperfect measure of Battery capacity because they are affected by additional factors separate from Battery capacity."
