General Motors made its first cash offers this week to 15 people it says have legitimate death or injury claims involving a faulty ignition switch in a group of cars dating as far back as 2003. The Detroit automaker’s internal compensation fund also said it has received an additional 175 injury or death claims since Friday, putting the total at 850, according to Reuters.

But critics say GM should greatly expand the number of cars whose owners could qualify for compensation, because millions of the company's other vehicles have similar key-slippage problems.

GM has so far accepted 21 death claims, and four claims related to serious injury such as paralysis or amputation. Those figures will rise as more claims are submitted. The company is offering at least $1 million for each death and set aside $400 million earlier this year to cover these costs.

Earlier this year GM established an internal victims’ compensation fund for its so-called Cobalt family recall announced in February and March in which the ignition switch can cause the car to stall, disabling airbags. But aside from the 2.59 million cars in the Cobalt family recall, GM has identified millions of other cars in which the ignition key can slip out of position and cause the same problem.

So why the distinction even if the results could be the same? According to GM spokesperson Alan Alder, the Cobalt family recall is the only one “that involves replacement parts.”

“The other vehicles recalled for this condition are receiving only a reworked ignition key -- making a hole where the slot was -- and/or additional key rings to separate weight on the key chain from having a levering effect and pulling the ignition to accessory mode from run mode,” Adler added in an email Wednesday to International Business Times.

What this means is that even if nearly 14 million GM vehicles have been identified with the key-slippage problem, only about one in five of them are covered by GM’s compensation fund administered by attorney and special adviser Kenneth Feinberg. The fund, which was set up as an alternative to victims suing GM in court, will accept claims through the end of the year. For many victims, this could be the only recourse because GM was absolved by a bankruptcy court of any product-defunct liabilities that occurred before it emerged from bankruptcy on July 10, 2009.

Clarence Ditlow, director of the D.C.-based Center for Auto Safety and an outspoken critic of the way GM is handling the liability claims, says the company is splitting hairs by only recognizing claims from the ignition switch part and not the ignition key.

“They should cover all ignition switch defects no matter how you categorize them,” he told IBTimes by email on Wednesday. “We think GM made a major mistake not covering all ignition switch problems.”

The following is all of the cars that GM has identified with key-slippage problems as of Aug. 27:
