SUBJECT: MODELS: Loss of Power Steering Assist – Replace Electric Power Steering Motor 2005-2010 Chevrolet Cobalt 2005 Pontiac Pursuit 2005-2006 Pontiac G4 2006 Pontiac G5 Pursuit 2007-2010 Pontiac G5 Equipped with Electric Power Steering 2005-2010 model year Chevrolet Cobalt vehicles; 2005 model year Pontiac Pursuit; 2005-2006 model year Pontiac G4; 2006 model year Pontiac G5 Pursuit; and 2007-2010 model year Pontiac G5 vehicles equipped with electric power steering. Some of these vehicles have a condition in which a sudden loss of power steering assist could occur at any time while driving the vehicle. If the power steering assist is lost, a chime will sound and a “Power Steering” message will be displayed in the Driver Information Center to inform the driver of the condition. Steering control will be maintained, as the vehicle defaults to a manual steering mode. If power steering assist is lost, it may require greater driver effort at low vehicle speeds, for example, below 15 mph (25 km/h). Unless a driver compensates for this additional effort, it may increase the risk of a crash. Typically, the next time the vehicle is started, the power steering assist will return and the “Power Steering” message will no longer be displayed. EPS Motor Replacement Procedure Note: The use of Loctite is no longer required. Loctite should not be used for any further applications. 1. Connect the Tech 2® to the vehicle and check for diagnostic trouble codes (DTCs). 2. Record any present DTCs on the repair order and during claim submission. 3. Clear any DTCs that are present. 4. Remove the power steering assist motor. Refer to Power Steering Assist Motor Replacement in SI. Note: For 2005 model year vehicles only: Do NOT install the o-ring between the motor assembly and the steering column assembly. The new service motor kit will include an o- ring, but DO NOT install the o-ring for 2005 model year vehicles only. 5. Install the new power steering assist motor. Refer to Power Steering Assist Motor Replacement in SI. 6. Perform Test Drive.

BACKGROUND Prolonged high under-hood temperatures may cause the power steering hose to deteriorate prematurely and may cause the hose to crack and leak power steering fluid. Power steering fluid leaking onto a hot exhaust pipe will generate smoke and could lead to an under- hood fire. CORRECTIVE ACTION Install a power steering feed hose kit. PARTS INFORMATION Power Steering Feed Hose Kit: P/N 06530-SEC-A00 (Contains power steering feed hose [with power steering pump-side O-ring attached] and power steering pressure switch O-ring.) REPAIR PROCEDURE NOTE: Take care not to spill power steering fluid on the body and other parts. Wipe off any spilled fluid at once. 1. Raise the power steering reservoir, then disconnect the return hose, and drain the reservoir. Plug the return hose nipple with a suitable cap. POWER STEERING RESERVOIR 6. Remove the power steering heat shield, then lower the vehicle to the ground. RETURN HOSE HOSE 7. Disconnect the power steering pressure switch connector. UPPER LEVEL LINE CONNECTOR 2. Connect a hose of suitable diameter to the disconnected return hose, and put the hose end in a suitable container. 3. Start the engine, let it run at idle, and turn the steering wheel from lock-to-lock several times. When fluid stops running out of the hose, shut off the engine. Discard the fluid. NOTE: Inspect the reservoir screen for any debris. If the reservoir screen is clogged, replace the reservoir. 4. Remove the cap from the return hose nipple on the reservoir, then reinstall the return hose on the reservoir. 5. Raise the vehicle on a lift, and make sure it is securely supported.
