As automobile manufacturers and part suppliers continue to experience delays in reopening factories in Japan after last weeks earthquake and tsunami, part shortages are starting to slow automobile production world wide. Toyota, Lexus, Honda, and Mazda have extended shutdowns in most of their Japanese factories, and the ones that have been reopened are not working at full capacity. According to analysts, auto makers will feel the worst of the shortages by early may and as many as five million vehicles will end up not being built because of it. It is estimated that about 13% of the world’s automotive production is out of commission.

The components most affected include semi-conductors, integrated circuits, sensors and LCD displays, but it won’t be long before shortages will also be seen in resins and synthetic rubber, power train parts, specialty materials such as silicon and certain types of glass and metals. General Motors announced that they will be suspending production of the Chevrolet Colorado and GMC Canyon pickup trucks in their Louisiana factory and plants near Buffalo, New York that makes engines for those trucks. Other automobile manufacturers, are expected to suspend building in some of their U.S. factories as parts continue to become more scarce.
