The National Highway Traffic Safety Administration is a step closer to concluding that General Motors should have recalled 384,000 Saturn Ions in 2010 as part of a larger recall that covered one million Chevrolets and Pontiacs for a steering problem.
The agency posted a document on its Web site over the weekend saying that it upgraded its investigation into Saturn Ions from the 2004-7 model years as a result of heightened concern that a sudden loss of electric power steering could cause crashes.
The document shows the agency has 846 complaints from Saturn owners and G.M. has almost 3,500. There were two reports of driver injuries from crashes.
