The recall, which covers 1.4 million vehicles dating to the 1997 model year, is needed because repairs from the first two didn't work. More than 1,300 cars caught fire after they were fixed by dealers, the company said.
In the previous recalls in 2008 and 2009, GM told owners to park the cars outside until repairs can be made since most of the fires happened shortly after drivers turned off the engines. A spokesman was checking to see if the same recommendation applies this time.
GM reports at least 19 minor injuries from the blazes, which have persisted since U.S. safety regulators first noticed them early in 2007. In 2008, a GM spokeswoman said the cars were responsible for 267 fires over the years, including at least 17 that burned structures.
