Federal safety officials have widened their investigation of Toyota's sticky gas pedals to see if the same problem could exist for other automakers.
The National Highway Traffic Safety Administration has sent a letter to CTS, the Indiana company that made the pedals behind Toyota's recall of millions of vehicles.
The safety agency wants to know more about pedals that CTS made for other auto companies.
CTS says it makes pedals for companies like Honda, Nissan and a small number of Ford vehicles in China.
CTS been adamant that the issues are limited to Toyota alone. Other automakers have also said their pedals are based on different designs and aren't at risk for the same problems.
