GM confirmed the recall to Autoblog via an emailed statement (which we've included below). According to the statement, the issue at hand in what is the company's 69th recall of 2014 covers the chassis-control module. Automotive News is reporting that a problem in the chassis-control system could cause a short in the module, which could cause the engine to stall or fail to start. The fault could also affect the trailer-brake control, provided it's equipped.
According to GM spokesman Alan Adler, the company doesn't know of any crashes, injuries or deaths due to the issue, and only one percent of the vehicles being recalled will need to have their chassis-control modules replaced.
