This is due to the incorrect font size of the warning lights, which increases the risk of an accident. This was announced by the US National Highway Traffic Safety Administration (NHTSA).

This is Tesla’s biggest recall yet, Reuters reported. Two months ago, Tesla had to recheck 2.03 million cars to install new safeguards in its advanced Autopilot assistance system. At the same time, Tesla is under scrutiny from the NHTSA because of its driver assistance system, which is supposed to allow vehicles to automatically steer, accelerate and brake within a lane.

The recall affects vehicles of various models, including the 2017 to 2023 Model S, Model X, Model 3, Model X and Cybertruck pickup trucks. Tesla added that Cybertruck cars now in production will have an update to fix the problem.

“Warning lights with a smaller font size can make it difficult to read safety-critical information on the instrument panel, increasing the risk of a crash,” according to NHTSA.

Tesla has started releasing a free software update over-the-air, i.e. without the need for a physical connection, to fix this problem. This will increase the font size of the brake, parking system and ABS warning lights.
