GM Recalls Another 2.7 Million Vehicles

General Motors Co. is launching five simultaneous recalls covering a combined 2.7 million cars and trucks most of them with taillamps and cruise control problems.

The flurry of campaigns underscores GM's newfound effort to find and fix safety problems faster. The company has launched more than two dozen recalls involving more than 11 million vehicles some of them part of multiple campaigns so far this year.

The primary recall involves 2.4 million cars with wiring harnesses that could corrode. If so, the brake lights may not work when they should or illuminate when they shouldn't. The same problem could disable the vehicle's cruise control, traction control, electronic stability control and panic braking assist features.

Affected cars include 2004-2007 Chevrolet Malibu Maxx hatchbacks, 2004-2012 Chevy Malibu sedans, 2005-2010 Pontiac G6 sedans and 2007-2010 Saturn Aura sedans.

GM also is recalling 140,100 of its 2014 model Chevy Malibu sedans equipped with the base 2.5-liter 4-cylinder engine and automatic engine stop-start. The campaign will reprogram flawed control software that could cut off brake boost, thus making it significantly more difficult to stop the vehicle.

A third large campaign covers 111,900 Chevrolet Corvettes from the 2005-2007 model years. GM says underhood heat could flex and eventually crack a wire to the low-beam headlamps, which would disable the lamps intermittently or permanently. GM says it also will fix the same problem in an undisclosed number of 2008-2013 Corvettes under a less rigorous customer satisfaction program.

Finally, GM plans two more small recalls. One will fix a problem that, under unusual conditions, could make the windshield wipers stop working on 19,200 of its 2013-2014 model Cadillac CTS luxury sport sedans. The second campaign will replace improperly installed steering tie rods on about 500 of its 2014-2015 fullsize Chevy Silverado and GMC Sierra pickup trucks.
