(WWJ) General Motors is recalling 320,000 big pickup trucks because of a fire risk.
The recall includes 2017-2019 heavy-duty Silverados and Sierras with diesel engines that have optional engine block heaters.
WWJ Newsradio 950's Jeff Gilbert reports a short circuit can develop in the cables or terminals, leading to smoke in the cabin or a fire.
GM said it had 24 fires reported in connection with this issue, but no injuries.
Some of these vehicles were recalled earlier, but will need another repair, according to the automaker.
For now, dealers will disconnect the engine block heater while GM works on a permanent fix.
Vehicle owners will be notified.
