On certain vehicles, water may not have been be removed completely from the harness connector of the fuel pump due to variations in the fuel tank leak check process performed before vehicle assembly.  As a result the connector pin may corrode, potentially causing the pin to break and the fuel pump to become inoperative.  This could cause the engine to stall and fail to restart, which could increase the risk of crash.  Correction: Dealers will inspect the fuel pump connector and if necessary the fuel pump will be replaced and the harness repaired.

On certain vehicles with Electro-Hydraulic Power Assist Steering (EHPAS), rust had formed inside the high-pressure pipe on the power steering system during manufacturing due to improper processing.  Rust particles may detach from the pipe walls and enter the motorized power steering pump, causing damage to the pump bearings.  As a result, gear lubrication may be reduced, leading to an increased load on the motor.  Should this happen, there is the potential for the power steering system to enter the fail safe mode in order to prevent overheating, resulting in the power steering warning lamp to light and the motorized pump to stop which could lead to a loss of power assist and the required steering effort will increase.  Correction: Dealers will flush the power steering system and repair as necessary.
