U.S. probes timing of GM reporting ignition problem: Secretary Foxx
"The questions we are asking are whether there was a timeliness issue" with GM bringing the problem to the attention of the National Highway Traffic Safety Administration, Foxx told a U.S. Senate hearing.
Foxx said if there are delays in the industry reporting problems, the Transportation Department will respond in a "very, very tough" manner.
