General Motors has issued six new recalls to address a range of flaws in more than 3.5 million vehicles worldwide. Included in that number are nearly 3.4 million Buicks, Cadillacs, and Chevrolets that may suffer from an ignition switch problem similar to the one that's kept GM in the headlines since February.

Here's a rundown of all the new recalls:

RECALL #1: Buick Lacrosse, Lucerne, Regal; Cadillac Deville, DTS; Chevrolet Impala, Monte Carlo

UNITS AFFECTED: 3,360,555

The biggest of today's recalls is similar to the ones involved in GM's ongoing "Switchgate" saga. In the vehicles listed below, GM says that "the ignition switch may inadvertently move out of the 'run' position if the key is carrying extra weight and experiences some jarring event".

Should that happen, the vehicle in question could lose power, disabling the power steering and brakes and making it much harder to control. In certain instances, GM says that losing power may prevent the airbags from deploying.

Unlike the Switchgate recall, however, the fix for these models centers not the ignition switch, but on the key and the slot it contains for accommodating key rings: "GM will add an insert to the ignition keys of the recalled vehicles to close the slot and leave a 4x6-millimeter hole through which the key ring could be attached. In vehicles where the key cover has been worn, new keys with holes instead of slots will be provided free of charge."

The vehicles included in this recall are

2005-2009 Buick Lacrosse

2006-2011 Buick Lucerne

2005 Buick Regal LS & GS

2000-2005 Cadillac Deville

2007-2011 Cadillac DTS

2006-2014 Chevrolet Impala

2006-2008 Chevrolet Monte Carlo

GM hasn't given a timeline for this recall, but says that owners should be notified "in the next few weeks". In the meantime, owners are urged to remove their car keys from key rings and to drive with only the ignition key.

RECALL #2: 2013-2014 Cadillac ATS, 2014 Cadillac CTS

UNITS AFFECTED: 109,031

This recall is meant to fix a dodgy shift cable on vehicles with automatic transmissions. In certain instances, GM says that the cable may detach from the shifter bracket or transmission bracket. If that happens, the driver won't be able to switch the vehicle in or out of gear.

GM hasn't given details about the fix for this problem or when the recall will begin.

RECALL #3: 2015 Chevrolet Silverado 2500/3500 HD, 2015 GMC Sierra 2500/3500 UNITS AFFECTED: 65,125

In some of these trucks, the power steering hose may not be properly clamped to the power steering pump. If the hose becomes disconnected, it could result in a rapid loss of power steering fluid, which, in turn, would result in the loss of power steering assist and Hydro Boost powered brakes. GM points out, however, that manual steering and brakes would remain fully functional.

Though GM hasn't indicated when this recall will begin, the automaker says that when it does, dealers will inspect the clamps on the power steering hose to ensure that they're properly attached.

RECALL #4: 2011 Cadillac CTS

UNITS AFFECTED: 18,279

In certain CTS models with all-wheel drive, a gasket leak may cause sensors to believe that the car is experiencing a rollover. If the rollover sensor is activated, the vehicle's roof rail airbags can deploy, causing a serious distraction at best, or at worst, injuring occupants.

GM knows of 15 unintended deployments of airbags but says that data on occupant injuries hasn't conclusively been linked to the airbags. The automaker hasn't detailed the fix for this problem or a timeline for owner notification.

RECALL #5: 2014 Chevrolet Corvette

UNITS AFFECTED: 961

This recall involves Corvettes that were delivered with Competition Sport Seats. If a child is traveling in the passenger's seat, and if that child isn't wearing a safety belt, a problem with the door trim could prevent the passenger's seat side air bag from deploying properly in the event of an accident.

The fix for this problem involves a redesigned airbag, which dealers will install free of charge. GM hasn't indicated when this recall will begin in earnest, but asks owners not to allow small children in the front seat until the vehicle has been fixed. (Pro tip: that might be good advice to follow even after the vehicle has been repaired.)

RECALL #6: 2014-2015 Chevrolet Silverado; 2014-2015 GMC Sierra UNITS AFFECTED: 184

The smallest of today's recalls involves pickup trucks that came with vinyl floors and all-weather floor mats. The factory mats have no attachments to hold them in place, and in certain instances, they can slide beneath the driver's feet.

GM hasn't said when it will send out notifications about the problem, but once that happens, owners will be able to take their vehicles to a dealership for a complete refund.
