Washington — General Motors Co. said Wednesday it is recalling about 250,000 vehicles in two new recall campaigns, including about 196,000 Hummer SUVs and trucks after reports of three injuries related to fires.

The Detroit automaker said it is recalling 196,000 2006-10 Hummer H3 and 2009-10 Hummer H3T SUVs because the connector module that controls the blower motor speed in the heating and air conditioning system may overheat and catch fire.

GM said it is aware of three reported minor burns but no crashes or fatalities. GM said it has confirmed 42 fires in all.

The recall includes nearly 165,000 vehicles in the United States. Dealers will replace the affected portion of the connector and harness.

GM ended its Hummer brand in 2010 after a deal to sell it to a Chinese company collapsed.

Separately, GM is recalling 50,731 2014-15 Chevrolet Sparks and 2015 Chevrolet Sonics because of a radio glitch.

GM says in some cars with base radios and OnStar, the radio software may cause the radio to lock up in the OnStar turn-by-turn directions mode.

If this occurs, the radio display will go blank and all audio functions will cease, including vehicle chimes related to warnings for a key left in ignition and driver safety belt not in use — a glitch that would violate a U.S. safety standard.

GM said in addition to the chime malfunction, the radio may not turn off. That could drain the battery and prevent starting. Dealers will reflash the radio software.

GM is unaware of any crashes, injuries or fatalities related to the recall. The callback includes about 45,000 vehicles in the U.S.
