Detroit ? Consumers frightened by the prospect of losing their jobs stayed away from auto showrooms again in January and sent U.S. car and truck sales falling 37 percent, a familiar refrain for the struggling industry but an unwelcome start to a critical year for U.S. carmakers.

Devastated by an economy in which few people have the spare cash to buy a car or can obtain the financing to do it, Chrysler’s domestic sales for January were less than half what they were a year earlier.

Sales fell 49 percent at General Motors and 40 percent at Ford. Toyota and Nissan’s sales each fell at least 30 percent.
