Ford, General Motors and DaimlerChrysler all lost some of their weekly production in the US and Canada because of this week's winter storms, Bloomberg News reports. Ford expects to lose production on about 11,000 vehicles this week, or 13 percent of its average weekly total, spokeswoman Della DiPietro told Bloomberg. The company expects it will be able to make up about 40 percent of the lost output. Both GM and DaimlerChrysler said facilities were affected, though they didn't disclose exact production figures.

The storms on Monday and Wednesday made it hard for employees to get to work and delayed suppliers' deliveries of parts to assembly plants, DiPietro said. Some Michigan counties received as much as 18 inches of snow on Monday, and Lenawee and Monroe counties south of Detroit got another 5 to 7 inches on Wednesday night.

"I can't think of an assembly plant that hasn't been affected by this," DiPietro said.

The Ford plants most affected by this week's storms were 13 factories in Ontario, Ohio and southeast Michigan, as well as the company's Twin Cities plant in Minneapolis. Some Ford stamping and powertrain plants may have lost some production, though they never shut down, Bloomberg said.

All of this comes after Ford said earlier this month that it would build 1.07 million cars and light trucks in the fourth quarter, down from a previous forecast of 1.11 million.

GM's Flint, Michigan, truck assembly plant shut down for the first shift on Tuesday morning after Monday's heavy snowfall blanketed cities including Flint and Pontiac, where the Pontiac East truck assembly plant was affected by workers unable to get to work after more than a foot of snow fell there, GM spokesman Dan Flores told Bloomberg News.

Flores also that said assembly plants such as its Baltimore van plant that builds the Chevy Astro and GMC Safari shut down its second shift yesterday after a supplier was unable to ship in needed parts. Other plants affected included Fort Wayne, Indiana; Wentzville, Missouri; and its Janesville, Wisconsin factory that builds full-size sport-utility vehicles. Most of the plants outside of Michigan were affected by parts shortages, he said.

Flores said some production was lost, though he declined to disclose the figure for "competitive reasons."

DaimlerChrysler plants "had some issues in terms of parts delivery," spokesman Trevor Hale told Bloomberg. He said DaimlerChrysler plants that were affected were in Michigan, Ohio, Ontario as well as its Belvidere, Illinois assembly plant west of Chicago that builds the Dodge and Plymouth Neons. He declined to say how much production was lost.
