Delphi Automotive, the supplier which produced the faulty, GM-designed ignition switch found in millions of the automaker’s small cars refused to cooperate with former U.S. prosecutor Anton Valukas’ investigation into the matter, USA Today reports.
Valukas and his law firm, Jenner & Block, were hired by GM to conduct an internal investigation into the company following its controversial ignition switch recall debacle. He was given full access to GM records and reviewed more than 40 million previously unseen documents and interviewed 230 witnesses to get to the bottom of the matter. Delphi wasn’t so cooperative, though.
“We made requests from them from the very beginning for access to any and all documents relating to this matter,” Valukas told members of Congress during GM’s hearing last week. “What they produced to us were a limited number of documents.”
In response, U.S. Rep. Lee Terry, R-Neb, asked Valukas if Congress should subpoena Delphi to obtain certain relevant documents. Valukas offered no opinion on the matter, USA Today says. Valukas did however say that Delphi knew the part was below typical GM specifications for torque. Records show Delphi also knew engineer of the switch, Ray Degiorgio, approved a change to the part in 2006 without altering the part number.
