A Toyota transmission, the vehicle’s powertrain, is under scrutiny after a test of the fluid showed it was contaminated with Zika virus.
The Centers for Disease Control and Prevention has said the virus is spreading rapidly and that there are no current reports of cases.
The agency has tested more than 100,000 Toyota vehicles, and the company says it has taken action to reduce exposure to the transmission fluid.
It said it has begun testing a variety of components in the transmission, including the engine, transmissions, brakes, brakes and tires.
The transmission fluid is made by Toyotas plant in Toyo, Japan, and is sold as part of a line of fluids that include air-conditioning fluid and heating oil.
Toyota spokesman Kevin Hickey said in a statement that the company has a comprehensive policy for protecting the health and safety of its customers.
“We have taken additional steps to reduce the risk of transmission of Zika virus, including removing the transmission fluids from our vehicles and conducting extensive testing,” Hickey wrote.
Toyotas vehicle is part of the Toyota Group’s Global Transportation Group, which makes and sells vehicles, buses and other equipment.
The company has about 700 factories worldwide, and has more than 400,000 workers.
