The largest of the four recalls covers 1.34 million Buick Enclave, Chevrolet Traverse and GMC Acadia sport-utility vehicles from 2009 to 2014 and Saturn Outlooks from 2009 to 2010 for front safety lap belt cables that can separate over time, the Detroit automaker said Tuesday.
The company also recalled nearly 1.1 million Chevrolet Malibus from 2004 to 2008 and Pontiac G6s from 2005 to 2008 because shift cables could wear out over time.
GM last week agreed to pay a $35-million fine as part of the U.S. government's regulatory investigation into how the company handled the recall of 2.6 million cars with potentially faulty ignition switches that have been linked to at least 13 deaths.
After GM last week recalled 2.7 million vehicles in the U.S., the company said it expected to take a charge of as much as about $200 million in the second quarter, primarily for the cost of recall-related repairs announced in the quarter.
On Tuesday, GM increased that to $400 million. GM took a $1.3 billion charge in the first quarter.
Other actions cover lower-volume 2015 models: 1,402 Cadillac Escalades and Escalade ESV SUVs and 58 Chevrolet Silverado HD and GMC Sierra HD pickups.
No fatalities are associated with any of tTuesday's recalls, GM said.
