The National Highway Traffic Safety Administration has expanded its investigation into Chevrolet Cruze engine fires to two model years.
In April, NHTSA began investigating two complaints concerning fires erupting in 2011 Cruze engine compartments. Now, Reuters is reporting that the government agency has added 2012 Cruze models to the list, upping the number of total vehicles from 177,000 to 370,000.
General Motors told Reuters it has cooperated with investigators and there have been no reported injuries or accidents related to the probe.
According to a pair of complaints filed on NHTSA's website, two Cruze sedans were on the the open road when smoke began streaming out from under the hood. A few minutes later, the cars were ravaged by fire.
"In two minutes, the car was fully engulfed and flames were 15-feet high," one complaint said. "GM needs to find out and correct this problem before someone get [sic] seriously hurt."
