“The Feinberg facility is a settlement program,” said Jim Cain, the G.M. spokesman. “It is designed to settle claims, rather than make rigorous engineering or legal judgments about the definitive causes of the accidents.”

In the fund’s regular weekly update released on Monday, Mr. Feinberg said that more than 4,300 claims for deaths and injuries had been filed.

Of that total, the fund has so far approved payments for 100 deaths and 184 injuries.

There are still 37 death claims and 589 injury claims that are under review, the fund said.

Camille Biros, the deputy manager of the program, said that many of the eligible death claims involve younger victims in their teens and early 20s. She said the fatalities involved passengers as well as drivers, including people sitting in the back seat of vehicles.

Some of the claims were made for accidents that occurred after G.M. began recalling the small cars last February. But Ms. Biros said there was no precise number available for post-recall victims.

G.M. set up the compensation fund last year after its internal investigation showed that dozens of engineers, lawyers and investigators inside the company had known about ignition problems for years but failed to fix them.
