Volvo warns some vehicle engines may exceed emission limits
from Reuters via MSN
Sweden's Volvo said an emissions control component used in its vehicles was degrading more quickly than expected, which could cause engines to exceed emission limits for nitrogen oxides, sending its stock down sharply. The company, which makes trucks, construction equipment and buses, said the largest volume of potentially affected engines had been sold in North America and Europe, its two largest markets, and that costs to fix the problem "could be material".
