Toyota Motor Corp. asked U.S. dealers to limit replacement-parts orders to those that are "critically needed" because supplies of some components from Japan likely will be disrupted, reported Bloomberg.

“Damage sustained by certain Japanese parts suppliers will interrupt their normal production,” the Toyota City, Japan- based company said in an e-mail to dealers today. While replacement-part inventories are adequate for now, about 233 components have been placed on controlled allocation out of more than 300,000 in use, Toyota said.

Toyota, the world’s largest automaker, has suspended most auto and parts production in Japan since the magnitude-9 earthquake and tsunami that has left more than 27,000 people dead or missing. The company said last week it expects some North American auto production to be reduced because of likely parts shortages.

Toyota’s U.S. sales unit is based in Torrance, California.
