More news seems to be coming in every day on the effects that the Japanese earthquake has had on automakers around the world, and analysts are still not sure quite how widespread the problems will be. However, recent word from the automakers involved seems to indicate that issues will continue for quite some time.

"We have no idea how bad this really is. The one thing I'm absolutely certain of is that everything is completely uncertain," Rebecca Lindland, veteran auto analyst at IHS Automotive, told USA Today.

Although the full extent of the complications may not be completely known, automakers have given some indication of what the future problems could be. Honda announced that it will be adjusting production levels at many of its North American factories, in some cases slashing hours in half. Subaru also announced that it will be cutting production at many plants.

Toyota, meanwhile, has said that workers should expect "some production interruptions" at the manufacturer's North American plants, although it has yet to make any official announcements. Still, the automaker took steps to address the shortage of critical parts that many manufacturers seem to be suffering from. Toyota has placed restrictions on dealers ordering parts for their repair shops, hoping to cut down on franchises panicking and "hoarding" parts.

With production levels down, it's possible dealers could be seeing vehicle shortages in the near future. Drivers planning on purchasing a vehicle may want to act sooner rather than later.
