General Motors says parts shortages caused by the earthquake in Japan still could hurt it.

But the company doesn't expect the shortages to have a big impact on its financial results for the year.

GM said in a statement Wednesday that it still could be forced to temporarily suspend production at factories around the world. It also may change production schedules.

But the company says it will make the best use of parts that are in short supply.

So far GM has seen little impact from the March 11 earthquake and tsunami that damaged many auto parts plants in northern Japan.

The damage has forced Japan-based automakers such as Toyota, Honda and Nissan to temporarily close plants or run them at half the normal output.
