A malfunction in the heating and cooling system of Hummer sport utility vehicles has led General Motors to recall around 196,000 of the vehicles; specifically the 2006-2010 Hummer H3 and the 2009-2010 H3T. The automaker announced the recall on Wednesday, saying that at least two Hummers were destroyed in fires caused by the electrical issue. While three people suffered burns from the fires, there have been no reported casualties.

These two fires are not isolated incidents. The National Highway Traffic Safety Administration (NHTSA) began receiving complaints regarding fires in the dashboard back in 2008, and Hummer drivers have lodged over twenty complaints about this issue. Additionally, Hummer representatives said that there have been 42 reported fires overall.

After an internal audit conducted this past June, the Transportation Department concluded that the NHTSA moved too slowly in completing investigations regarding consumer complaints. Safety agency administrator Mark R. Rosekind blamed the agency’s lack of resources for this failure when he appeared before a congressional subcommittee last month. It has been pointed out that Rosekind’s explanation is in direct opposition to his predecessors’ statements that the agency was satisfactorily funded.
