Tesla is recalling all 3,878 Cybertrucks it has shipped since the vehicle was released in late 2023, according to a Friday filing from the US National Highway Traffic Safety Administration (NHTSA), following reports of a faulty accelerator pedal.

Cybertruck owners reported the vehicle’s accelerator pedal pad could come loose and get lodged in the interior trim, causing the vehicle to accelerate unintentionally, and increasing the risk of a crash, the auto safety regulator said in a notice.

While recalls are not uncommon in the auto industry, the stop-sale order is a major blow to Tesla, which began deliveries of its Cybertruck electric pickup truck late last year after a two-year delay due to production problems and battery-supply constraints.

The company’s shares fell nearly 3% before the bell on Friday, adding to its five-session losing streak during which the stock lost about 14%.

Tesla will replace or repair the accelerator pedal assembly at no charge and owners will be notified through letters mailed to them in June, the NHTSA said.

In the first quarter of 2024 the EV maker had three recalls affecting about 2.4m vehicles, according to a report by recall management firm BizzyCar. However, most issues related to Tesla recalls are usually resolved through over-the-air software updates.

In February, Tesla recalled about 2.2m vehicles in the United States due to an incorrect font size on warning lights and US safety regulators upgraded their investigation into the company’s vehicles over power steering loss to the status of an engineering analysis.
