Toyota Motor North America is recalling 21,700 vehicles in the U.S. after discovering two defects that could lead to fires.

The separate recalls affect 11,800 2018 Toyota Camry sedans and 9,900 Lexus vehicles including, RC F vehicles from 2015-18 model years, GS F vehicles from 2016-18 model years, and 2018 LC 500 vehicles, the company said Wednesday.

The Toyota Camrys could have fuel pipes and fuel hoses in the engine compartment that were connected improperly, which could lead to a fuel odor or leakage and possibly result in a fire, Toyota said in a notice.

Owners of the affected Camrys will be notified by mail starting in late March, the company said. Toyota dealerships will check the fuel lines in the recalled vehicles and properly connect them, if needed.

In the recalled Lexus vehicles, which come with two high-pressure fuel pumps, the cover of one of the pumps could potentially "become damaged over time," and result in a fuel leak that could increase the risk of a fire, Toyota said.

Starting in early April, owners of the recalled Lexus vehicles will be notified by mail, Toyota said. Lexus dealers will replace both high-pressure pumps with updated ones.

A Toyota spokesperson declined to comment on whether the company is aware of any injuries or crashes are related to the recall, citing company policy.
