Tesla faces a proposed class action claiming it speeds up odometers on its electric vehicles so they fall out of warranty faster, saving Elon Musk's company from having to pay for repairs.

Tesla's basic warranty is active for four years or 50,000 miles. In a new class-action suit, one driver says his Tesla inflated miles driven by 117% over what he actually drove.

Tesla is facing a proposed class action lawsuit in California. The plaintiff alleges the company inflates the readings on the distance-measuring odometers in its vehicles to reduce warranty periods and steer people to purchase extended warranties.
