Federal safety inspectors have reported that Tesla is recalling 2.2 million of its cars on US roads due to warning light text sizes that are too small.

The National Highway Traffic Safety Administration, which said it found the issue during a routine examination of Tesla vehicles, issued the recall.

The agency’s notification states that “warning lights with a smaller font size can make critical safety information on the instrument panel difficult to read, increasing the risk of a crash.”

According to Tesla, there have been no collisions or injuries as a result of the issue.

An over-the-air software update will resolve the issue, saving Tesla customers from having to take their cars to a service facility.

Most Teslas on US roads are covered by the recall, but not all of them. The recently announced Cybertruck pickup, the Model S and Model 3 car up to and including the 2023 model year, and the Model X and Model Y SUV up to and including the current 2024 model year are among the models that are covered.

Compared to some of the other recalls the manufacturer of electric vehicles was ordered, this one is significantly less serious. Following the NHTSA’s two-year investigation into about 1,000 crashes in which the Autopilot feature was activated, another over-the-air recall was mandated in December to restrict the usage of the feature.

The NHTSA discovered that cars using the feature would break traffic laws, such as “traveling straight through an intersection while in a turn-only lane, entering a stop sign-controlled intersection without coming to a complete stop, or proceeding into an intersection during a steady yellow traffic signal without due caution.” A year ago, Tesla also recalled all 363,000 US vehicles that were then on the road with its “full self-driving,” or FSD, feature.

Additionally, incidents involving Tesla vehicles using various driver assist technologies are being looked into by the NHTSA and the National Transportation Safety Board. These occurrences include a number of crashes into emergency vehicles that were responding to other accidents.

Although technology is still in the beta stage, Tesla’s promise of a self-driving car is a key selling factor to investors and consumers alike, even if the firm now charges more for FSD.
