U.S. auto-safety regulators have opened up an inquiry into reports of fires in the doors of several models of Toyota vehicles, officials said Friday.
A Toyota spokesman said the National Highway Traffic Safety Administration investigation "involves potentially" 830,000 vehicles, with the focus on 2007 Camrys and RAV4s.
The automaker said it received a preliminary notice of the issue from NHTSA last week.
"However, we have not received an information request from the NHTSA. Toyota will fully cooperate with the agency in its efforts to investigate these allegations," he said.
The concerns came from six cases of fires erupting in the driver-side doors of Toyota vehicles.
Toyota's reputation was hit hard in 2009-2010 when it had to issue a recall for some 10 million vehicles around the world, most of them in the United States, for a series of technical problems.
