Defect
On certain vehicles, the tension adjuster pulley for the drive belt, which operates the alternator, water pump, air conditioner compressor and power steering pump, may contain an improperly manufactured internal spring that can break due to repeated stress. Should the spring break, this would cause the drive belt tension to be maladjusted, allowing the belt to slip. If the belt comes off, the loss of steering power assist would require the driver to exert increased effort to steer the vehicle. This could result in a crash causing property damage and/or personal injury. Additionally, the loss of water pump function would cause the coolant temperature to rise, which can lead to engine overheating, while the loss of alternator charging ability would lead to battery discharge and eventual engine stall.
Safety Risk
No risk description available.
Remedy
Dealers will replace the drive belt tension adjuster pulley.
