A compensation fund for wrongful death and injuries caused by faulty ignition switches in GM vehicles is unlimited, counsel hired by GM said Monday.

Kenneth Feinberg, hired by GM to oversee compensations, said the Detroit automaker has no placed no limits on its funds for those injured people or the relatives of those killed in vehicles with the ignition switches plaguing the company.

So far, GM says it's been able to link 13 deaths to the ignition switch issue.

The fault in the ignition switch could cause a car's engine to shut off unexpectedly. This in turn could cut off power steering and brakes. Air bags may be turned off if the ignition switch fails, though Feinberg said air-bag deployment means something else caused the crash.

Feinberg, who led the compensation efforts for the Sept. 11, 2001, terrorists attacks and the BP oil spill, said he, and not GM, will decide who gets what in the ignition switch claims.

Feinberg said it may be hard to determine exactly what caused the crashes because many vehicles have since been destroyed.

GM has recalled more than 2 million vehicles earlier this year to replace the faulty switches.
