# Product Safety - Drive Axle Pinion Seal Leak-Replace Seal

Subject: | 07204B -- Drive Axle Pinion Seal Leak - Replace Seal

Models: | 2005-2007 Cadillac CTS, CTS-V, SRX, STS

| 2006-2007 Cadillac STS-V

| 2007 Daewoo G2X

| 2007 Opel GT

| 2006-2007 Pontiac Solstice

| 2007 Saturn SKY

The service procedure and claim information in this bulletin have been revised. An inspection procedure has been added for vehicles that have previously had a complete axle replacement. In addition, a Notice statement has been added to the service procedure to inform technicians to use specified tools in SI and to take care when installing a new seal to prevent damage to the pinion seal.

### Condition

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2005-2007 model year Cadillac CTS, CTS-V, SRX, STS; 2006-2007 model year Cadillac STS-V; 2007 model year Daewoo G2X and Opel GT; 2006-2007 model year Pontiac Solstice; and 2007 model year Saturn SKY vehicles. The drive axle differential seal (two on all-wheel drive vehicles) may leak because it does not meet GM's specifications. If a seal is leaking, there will be fluid on the ground where the vehicle is parked. If enough fluid leaks, the differential will become noisier because of reduced lubrication. After about two-thirds of the differential fluid is lost, the bearings may no longer be lubricated and may start to overheat. Damage to the bearings and other differential components could then occur. Damaged bearings will create noise that may be heard by the vehicle occupants. If the vehicle is not repaired and damage progresses, three conditions can occur: (1) When the vehicle is stopped and shifted to reverse, the differential may jam and prevent vehicle movement; (2) the damage can cause drag that will feel like the brake is applied; or (3) the differential could jam and lock the drive wheels while the vehicle is in motion. If (3) occurs, the driver may not be able to control the vehicle and a crash could occur without warning.

### Correction

Dealers/retailers are to install a new drive axle differential seal (two on all-wheel drive vehicles).

### Vehicles Involved

Involved are certain 2005-2007 model year Cadillac CTS, CTS-V, SRX, STS; 2006-2007 model year Cadillac STS-V; 2007 model year Daewoo G2X and Opel GT; 2006-2007 model year Pontiac Solstice; and 2007 model year Saturn SKY vehicles built within these VIN breakpoints:

### Customer Notification - For US and Canada

General Motors will notify customers of this recall on their vehicle (see copy of customer letter included with this bulletin).

### Customer Notification - For Export

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

### Dealer Recall Responsibility - For US and Export (US States, Territories, and Possessions)

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.

### Dealer Recall Responsibility - All

All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

February 2008

Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has decided that a defect that relates to motor vehicle safety exists in certain 2005-2007 model year Cadillac CTS, CTS-V, SRX, STS; 2006-2007 model year Cadillac STS V; 2007 model year Daewoo G2X and Opel GT; 2006-2007 model year Pontiac Solstice; and 2007 model year Saturn SKY vehicles. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.

Important:

• | Your vehicle is involved in safety recall 07204.

• | Schedule an appointment with your GM dealer/retailer.

• | This service will be performed for you at no charge.

Why is your vehicle being recalled?

The drive axle differential seal (two on all-wheel drive vehicles) may leak because it does not meet GM's specifications. If a seal is leaking, there will be fluid on the ground where the vehicle is parked. If enough fluid leaks, the differential will become noisier because of reduced lubrication. After about two-thirds of the differential fluid is lost, the bearings may no longer be lubricated and may start to overheat. Damage to the bearings and other differential components could then occur. Damaged bearings will create noise that may be heard by the vehicle occupants. If the vehicle is not repaired and damage progresses, three conditions can occur: (1) When the vehicle is stopped and shifted to reverse, the differential may jam and prevent vehicle movement; (2) the damage can cause drag that will feel like the brake is applied; or (3) the differential could jam and lock the drive wheels while the vehicle is in motion. If (3) occurs, the driver may not be able to control the vehicle and a crash could occur without warning.

What will we do?

Your GM dealer/retailer will install a new drive axle differential seal (two on all-wheel drive vehicles). This service will be performed for you at no charge . Because of service scheduling requirements, it is likely that your dealer/retailer will need your vehicle longer than the actual service correction time of approximately 1 hour and 20 minutes to 2 hours and 50 minutes.

If your vehicle is within the New Vehicle Limited Warranty your dealer/retailer may provide you with shuttle service or some other form of courtesy transportation while your vehicle is at the dealership/facility for this repair. Please refer to your Owner’s Manual and your dealer/retailer for details on courtesy transportation.

What should you do?

You should contact your GM dealer/retailer to arrange a service appointment as soon as possible. Bring the enclosed customer reply form with you when you visit your dealer/retailer. The form identifies the repairs required. If you no longer own this vehicle, please let us know by completing the form and mailing it back to us.

Did you already pay for this repair?

The enclosed form explains what reimbursement is available and how to request reimbursement if you have paid for repairs for the recall condition.

Do you have questions?

If you have questions or concerns that your dealer/retailer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below. More information about this recall can be found at the Owner Center at MyGMLink, http://www.gm.com/recall
