Toyota is recalling 50,000 2014 Toyota Highlander and Highlander Hybrid crossovers in the U.S., according to the National Highway Traffic Safety Administration.

The vehicles are being recalled for improper seatbelt-restraint software.

Toyota has asked its dealers to stop selling the vehicles until repairs are made.

"The affected vehicles may have improper software installed in the airbag electronic control unit for the operation of the front-passenger seatbelt force limiter, and as a result, the force limiter may use the restraint setting designed for small occupants, such as those that weigh approximately 110 pounds, for all occupants regardless of their size," said the NHTSA regarding the issue.

Toyota has not said if any injuries, crashes or fatalities have occurred as a result of the issue.

No other Lexus, Scion, and Toyota vehicles are involved in the recall, according to the automaker.

"There are no warnings that this condition exists," Toyota told safety regulators.

The issue was first discovered during internal confirmation testing.

Toyota dealers will install a software update in the airbag electronic control unit if necessary.

All repairs will be completed free of charge.

"In the event of a crash, a larger front-passenger seat occupant may not be properly restrained and be at an increased risk of injury," said the NHTSA.

The recall will begin sometime before the end of this month.
