Tesla Inc (TSLA.O) is recalling more than 475,000 of its Model 3 and Model S electric cars to address rearview camera and trunk issues that increase the risk of crashing, the U.S. road safety regulator said on Thursday.

Tesla shares fell as much as 3% in the morning but rebounded and were last trading slightly higher around $1,088.76. The federal regulator has been discussing another camera issue with the automaker, while probing the electric vehicle manufacturer’s driver assistant system and other issues.

The model years affected in the recall range from 2014 to 2021, and the total number of recalled vehicles is almost equivalent to the half a million vehicles Tesla delivered last year.

The U.S. electric vehicle manufacturer is recalling 356,309 2017-2020 Model 3 vehicles to address rearview camera issues and 119,009 Model S vehicles due to front hood problems, the National Highway Traffic Safety Administration (NHTSA) said.

Tesla could not be reached for comment.

For Model 3 sedans, “the rearview camera cable harness may be damaged by the opening and closing of the trunk lid, preventing the rearview camera image from displaying,” the NHTSA said.

Tesla identified 2,301 warranty claims and 601 field reports regarding the issue for U.S. vehicles.

For Model S vehicles, front hood latch problems may lead a trunk to open “without warning and obstruct the driver’s visibility, increasing the risk of a crash,” Tesla said.

Tesla said it was not aware of any crashes, injuries or deaths related to the issues cited in the recall of Model 3 and Model S cars, the NHTSA said.

CNBC had reported that Tesla was replacing defective repeater cameras in the front fenders some U.S.-made vehicles without recalling the parts.

The NHTSA has been investigating 580,000 Tesla vehicles over the automaker’s decision to allow games to be played on car screens while they are in motion

Tesla has subsequently agreed to stop allowing video games to be played on vehicle screens while its cars are moving, according to the NHTSA.

Under pressure from NHTSA, Tesla in February agreed to recall 135,000 vehicles with touch-screen displays that could fail and raise the risk of a crash.

In August, the NHTSA opened a formal safety probe into Tesla Inc’s driver assistance system Autopilot after a series of crashes involving Tesla models and emergency vehicles.
