Summary
Some of the affected all-wheel driver (AWD) vehicles were assembled with mismatched front to rear final drive gear ratios. AWD vehicles with mismatched gear ratios may exhibit front end shudder upon acceleration and/or the Traction Control System (TCS) may activate. If the TCS activates, an icon on the cluster advising the driver that the TCS is active may illuminate, leading to engine torque reduction to slow the vehicle. The transfer case clutch will continue to wear until AWD function becomes unavailable.
Some of the affected rear wheel drive (RWD) vehicles were assembled with incorrect rear final drive gear ratios. Drive characteristics are not noticeably changed.

Customer Satisfaction Program 20B35
Your Vehicle Identification Number (VIN): 12345678901234567
At Ford Motor Company, we are committed not only to building high quality, dependable products, but also to building a community of happy, satisfied customers. To demonstrate that commitment, we are providing a no-charge Customer Satisfaction Program for your vehicle with the VIN shown above.
Why are you receiving this notice? | Your vehicle’s rear axle may have been built with an incorrect gear set, resulting in an axle ratio mismatch. |
What is the effect? | For all wheel drive (AWD) vehicles with an axle ratio mismatch, the front end may exhibit shudder upon acceleration and the Traction Control System (TCS) may activate leading to engine torque reduction which may slow the vehicle. An icon on the cluster advising the driver that the TCS is active may illuminate. With an axle ratio mismatch, the transfer case clutch will continue to wear until AWD function becomes unavailable.
For rear wheel drive (RWD) vehicles, the driver is unlikely to notice any change in drive characteristics. |
What will Ford![]() | In the interest of customer satisfaction, Ford![]() If your vehicle is an AWD, your dealer will:
Repairs will be free of charge (parts and labor) under the terms of this program. This Customer Satisfaction Program will be in effect until October 31, 2021, regardless of mileage. Coverage is automatically transferred to subsequent owners. |
How long will it take? | The time needed for this repair varies from one-half day to one and one-half days, depending on the required repair. However, due to service scheduling requirements, your dealer may need your vehicle for a longer period of time. Additional time may be required to allow the engine to cool prior to performing this repair. |
COVID-19 (CORONAVIRUS) | Ford![]() ![]() ![]() |
What should you do? | Please call your dealer without delay to schedule a service appointment for Customer Satisfaction Program 20B35. Provide the dealer with your VIN, which is printed near your name at the beginning of this letter.
If you do not already have a servicing dealer, you can access www.Fordowner.com for dealer addresses, maps, and driving instructions. Ford NOTE: You can receive information about Recalls and Customer Satisfaction Programs through our FordPass App. The app can be downloaded through the App Store or Google Play. In addition there are other features such as reserving and paying for parking in certain locations and controlling certain functions on your vehicle (lock or unlock doors, remote start) if it is equipped to allow control. |
Do you need a rental vehicle? | Your dealer is authorized to provide a rental vehicle for your personal transportation at no charge (except for fuel, insurance, and tax) while your vehicle is at the dealership for repairs. Please see your dealer for guidelines and limitations. |
What if you no longer own this vehicle? | If you no longer own this vehicle, and have an address for the current owner, please forward this letter to the new owner.
You received this notice because our records, which are based primarily on state registration and title data, indicate that you are the current owner. |
Can we assist you further? | If you have difficulties getting your vehicle repaired promptly and without charge, please contact your dealership’s Service Manager for assistance.
RETAIL OWNERS: If you have questions or concerns, please contact our Ford For the hearing impaired call 1-800-232-5952 (TDD) .
