It seems that the cause of the problem is a starter or alternator cable that comes in contact with the power steering return line.
The Detroit, Michigan-based auto giant said that such contact could cause wear and tear through the power steering line causing a leak and a loss of power steering.
Contact may also wear the cable protective wrap, conduit and wire insulation, so if there is metal to metal contact it could lead to the battery being drained. If the exposed battery cable separates from the power-steering line, sparks could form and a hole could be melted in the line. If the power steering fluid comes in contact with hot metal parts of the engine, there could be a fire.
As of November 19, owners will be notified by letters to take their vehicles to a GM dealer. A mechanic will inspect harness routing and correct as needed to eliminate contract with the power steering line.
The company added that any repairs related to this condition will be performed free of charge. Unsold models of these cars are being held on dealer lots until repairs can be made.
Four reports of fires have been recorded, but no injuries have been associated with this issue, according to a press release from the company.
