DETROIT (USA TODAY) -General Motors announced three new recalls, not related to lastmonth's ignition switch recall, and said it will take a $300 millioncharge against first-quarter earnings to pay for the four recalls.

Thebig automaker said the trio of new recalls is "a result of (CEO) MaryBarra's request for a comprehensive internal safety review following theignition switch recall."

Last month's switch recall involves 1.37million vehicles in the U.S. and has triggered lawsuits and federalinvestigations. GM records show it knew of a problem with the switchesin 2001, and federal agencies want to know why it only now recalled thecars.

GM says it knows of 31 crashes and 12 deaths as a result ofthe problem. A new probe in Canada could link a recent death there tothe recalled cars.

The new recalls, which are not connected to the earlier action:

•Seat-mounted side airbags could fail due to a fault in the wiring in1.18 million full-size crossover SUVs, widely used as family vehicles:

2009-2013 Chevrolet Traverse

2008-2013 Buick Enclave

2008-2013 GM Acadia

2008-2010 Saturn Outlook

GMsays the problem happens if the airbag warning light on the instrumentpanel illuminates, but the owner doesn't take the vehicle to adealership to check the issue. Eventually, the wiring can fail and thebags won't work.

Dealers will remove a connector and solder and splice wires in the air bag harness.

GM says it has no record of injuries or accidents as a result of the problem.

•Aplug in the brake system of 63,900 2013 and 2014 Cadillac XTS full-sizesedans can come loose, allowing corrosion in the system, causingoverheating that can lead to engine-compartment fires.

GM says ithas reports to two fires at dealerships in dealer-owned cars, and tworeports of warranty claims, but not fires, in customers' cars.

No injuries have been reported.

•Unbeltedfront passengers in full-size Chevrolet Express and GMC Savanafull-size vans can suffer serious head injuries because the materialcovering the passenger-side air bag doesn't meet federal standards.

Passengers who wear safety belts are not at risk, GM says.

Involvedare 303,000 2009-2014 vans with gross vehicle weight ratings of lessthan 10,000 lbs. often known as standard-day and medium-duty models.Such vans mostly are for commercial use by plumbers, electricians,building contractors and so on. Some are used as passenger shuttles byhotels, airports and churches.

GM issued a "stop delivery" order for models still at dealerships, until a fix can be developed.

Thecar company says it is "working diligently" to come up with materialsthat will meet the head-injury standard for non-belted riders, but can'tsay how long that will take.
