The National Highway Traffic Safety Administration (NHTSA) announced Wednesday that Tesla Inc (TSLA.O) is recalling 26,681 cars in the United States due to a software fault that might cause windshield defrosting issues.

According to Tesla, the issue might induce an inadvertent opening of a valve in the heat pump, trapping the refrigerant within the evaporator. Tesla will fix the problem with an over-the-air software upgrade.

Some Model 3 vehicles from 2021-2022, Model S vehicles from 2021-2022, Model X vehicles from 2020-2022, and Model Y vehicles from 2020-2022 may fail to meet a federal motor vehicle safety requirement. It's the latest in a long line of recalls for the Texas-based electric vehicle maker.

Tesla claimed it was not aware of any injuries or incidents as a result of the recall, but the National Highway Traffic Safety Administration stated it might impair windshield visibility in certain situations, thereby increasing the danger of a collision.

Customers complained in December about a loss of heating effectiveness during extremely cold weather, according to the business.

Tesla issued a software update on Jan. 15 to fix the issue as a preventive measure. Tests were done to check the compliance of new cars supplied with the software command after consultations with NHTSA and Transport Canada.

Tesla has issued a slew of recalls in recent months, many of them due to software concerns, as it has been under fire from US authorities and politicians.

Tesla has issued at least nine recalls in the United States since October, in response to regulatory inquiries into its driver assistance system Autopilot and an in-vehicle gaming function.

Tesla agreed to recall 135,000 vehicles with potentially defective touchscreen screens in January 2021, after the National Highway Traffic Safety Administration took the uncommon step of publicly requesting the recall.

Touchscreen failures, according to the agency, can result in the loss of rearview or backup camera pictures, exterior turn-signal illumination, and windshield defogging and defrosting systems, among other things.
