The largest recall is for 414,333 vehicles and involves a problem with a potentially loose bolt on seat adjustment mechanisms. The recall includes: Chevy Camaro (model year 2011-2012); Chevy Equinox (2010-2012); GMC Terrain (2010-2012); Buick Regal and LaCrosse (2011-2012 for both); Cadillac SRX (2010-2012).
GM says that the bolt that secures the height adjuster actuator may become loose or fall out. If the bolt falls out, the seat will move up and down freely because it is no longer attached at the height adjuster.
Owners of these vehicles are advised to NOT use the power height adjustable feature until dealers can replace the height adjuster bolt.
The car maker says it knows of one crash and three injuries (no fatalities) related to this defect.
This one is for 124,007 vehicles — Chevrolet Caprice (2014), Chevrolet SS (2014), Chevrolet Silverado LD and HD (2014-2015), Cadillac ATS (2013-2014), Cadillac CTS (2014), Cadillac ELR (2014), Buick Encore (2013-2014), GMC Sierra LD and HD (2014-2015) — that GM says may have an incomplete weld on the seat hook bracket assembly.
Dealers will inspect the weld on affected vehicles to determine if it is sufficient. If so, no further action is necessary. If it is insufficient, dealers will replace the lower seat track at no charge.
GM, which says it knows of now crashes or injuries from this problem, believes that fewer than 1 percent of welds are expected to require seat track replacement.
Another 120,426 vehicles — Buick Regals (2011-2013) and Chevrolet Malibus (2013) — are being recalled over a problem with the front turn signals. These cars have two bulbs in each of the signals. When any of the bulbs fail, the driver should be signaled by a rapidly flashing turn signal arrow in the dashboard. But this is apparently only happening when both bulbs fail. If only one bulb on either side burns out, there is no signal to the driver.
GM says that its dealers will reprogram the body control module to fix the condition.
This one involves 57,242 Chevrolet Impalas (2014) equipped with belt-drive electric power steering.
According to GM, customers may experience reduced or no power steering assist at start-up or while driving due to a poor electrical ground connection to the Power Steering Control Module.
The cause of the problem is believed to be paint that may have seeped behind the nut on the power steering control module ground stud.
To fix the issue, dealers will inspect and clean paint from behind the ground nut, re-torque the nut and update the power steering control module software at no charge.
GM knows of one crash related to this problem, but says that no injuries or fatalities resulted.
This relatively small recall of 1,919 Chevrolet Sparks (2014-2015) involves vehicles imported from Korea that were assembled with a lower control arm bolt not fastened to specification.
The condition could result in noise from the front suspension and separation of the lower control arm from the steering knuckle while driving resulting in loss of steering control.
Dealers will inspect the left and right hand lower control arm attaching bolts to assure they are tightened to specification.
GM is recalling 22 model year 2015 Chevrolet Tahoe/Suburban and GMC Yukon/Yukon Denali vehicles on which the roof carriers may have been attached with the wrong retaining nuts, resulting in holes or tears in the roof rail air bags if they deploy.
This recall is even smaller than the 22 number might indicate, as 8 these vehicles are still in dealer stock.
