General Motors has issued a recall on more than 55-thousand vehicles. The vehicles can be shifted out of park and roll away, even when the key isn't in the ignition. The 2013 models of Chevy Avalanche, Express, Silverado, Suburban, and Tahoe are all included in the recall. The GMC Sierra, Savana, and Yukon and Cadillac Escalade are also on the list. Dealers will fix the problem free of charge.
