DETROIT — Negotiations over a new four-year contract between Chrysler and the United Auto Workers have broken down as both sides refuse to budge on key financial issues.

The talks ended late Wednesday in a dispute over the number of workers who are paid an entry-level wage. Chrysler, which is losing money, wants no limit on cheaper entry-level workers. The union wants a cap on the number of those workers, who make $14 to $16 an hour, about half of what a longtime union employee earns. Chrysler factories continue to operate under a contract extension.

Detroit’s three carmakers are each negotiating labor agreements with the UAW, which represents 113,000 workers at the companies. The new contracts would be the first since two of the automakers — GM and Chrysler — nearly collapsed during the recession and needed government bailouts in 2009.
