NHTSA opens fresh investigation into GM vehicles over possible engine failures
The Center for Auto Safety is the nation’s premier independent, member driven, non-profit consumer advocacy organization dedicated to improving vehicle safety, quality, and fuel economy on behalf of all drivers, passengers, and pedestrians.
Michael Brooks, executive director of the Center for Auto Safety, said vehicle owners under recall should check with a technician as soon as possible to determine if their engine needs replacement.
“It’s hard for an owner to know exactly what to do right now. Owners might want to consult with their dealer while we await the outcome of this investigation,” he said. “Anytime you have a vehicle that loses the ability to move on an active roadway ― that’s a big crash risk. Stalling, or loss of automotive power as NHTSA refers to it, is one of the most important defects the agency looks into.”

The National Highway Traffic Safety Association has opened a fresh probe into General Motors vehicles for engine failure risks after the agency received a flood of consumer complaints.
GM said the issue, described by NHTSA as “loss of motive power due to engine failure,” could be caused by manufacturing defects to a vehicle’s connecting rod and crankshaft engine components. GM determined the engine failures were due to multiple supplier manufacturing and quality issues.
The new engineering analysis covers 286,000 vehicles that were part of NHTSA’s original investigation but weren’t covered under a voluntary recall that GM issued earlier this year.
