The National Highway Traffic Safety Administration (NHTSA) has opened two separate investigations into reported electrical fires in General Motors vehicles, according to an AP report.

One investigation concerns the 1995-1997 models of the Chevrolet Cavalier and Pontiac Sunfire. The second investigation is for 1998 C/K trucks.

The report says that the NHTSA has received 18 reports alleging a steering column fire in a Cavalier or Sunfire. Ten complaints said the ignition was off when the fire started, and two people reportedly were injured by smoke inhalation.

The report adds that at this point in the cases, the agency is exchanging paperwork with the manufacturer. Investigations can lead to a subsequent recall, but many are dropped.
