DETROIT (CNN/Money) - General Motors Corp. is recalling more than 2 million vehicles, mostly sold in the United States, on a variety of potential safety defects, the company said Monday.

GM said it knew of no injuries incurred due to any of these potential defects, but that it was aware of two minor crashes.

GM (down $0.41 to $26.33, Research) shares fell in early Monday trading.

GM, the world's largest automaker, said the largest of the recalls includes nearly 1.5 million pickup trucks and sport/utility vehicles with second-row seat belts that may be difficult to properly position across passengers' hips.

Dealers will repair the safety belts for free, the company said in a statement.
