This Customer Satisfaction Program applies to vehicles originally sold in, or currently registered in the following states:

ConnecticutIowaMinnesotaOhioWisconsin
DelawareMaineMissouriPennsylvania
District of ColumbiaMarylandNew HampshireRhode Island
IllinoisMassachusettsNew JerseyVermont
IndianaMichiganNew YorkWest Virginia

 

REASON FOR THIS PROGRAM

In the affected vehicles, corrosion on the high voltage lower battery connector may cause deformation of the connector allowing water ingress.  Water ingress into the high voltage lower battery could result in a high voltage circuit isolation fault with a “Stop Safely Now” message displayed in the message center.  If this occurs, the vehicle may not restart once it has been shut off.

 

SERVICE ACTION

Before delivering any of the vehicles involved in this program, dealers are to remove the high voltage lower battery from the vehicle, clean and inspect the high voltage lower battery connector, apply corrosion protection, install a protective shield and reinstall the high voltage lower battery in the vehicle.  This service must be performed on all affected vehicles at no charge to the vehicle owner. NOTE:  The high voltage lower battery in some vehicles may require shipment to a specialized facility to complete repairs.

 

OWNER NOTIFICATION MAILING SCHEDULE

Due to capacity constraints to repair the high voltage lower battery, and to assist dealers in managing customer expectations, owners of affected vehicles will be notified in four separate mailings. Mailing will begin by March 28, 2016.  Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.

 

STOCK VEHICLES

  • Correct all affected units in your new vehicle inventory before delivery.
  • Use OASIS to identify any affected vehicles in your used vehicle inventory.

 

SOLD VEHICLES

  • Owners of affected vehicles will be directed to dealers for repairs.
  • Immediately contact any of your affected customers whose vehicles are not on your VIN list but are identified in OASIS. Give the customer a copy of the Owner Notification Letter (when available) and schedule a service date.
  • Correct other affected vehicles identified in OASIS which are brought to your dealership.  

 

TITLE BRANDED / SALVAGED VEHICLES

Affected title branded and salvaged vehicles are eligible for this service action.

 

OWNER REFUNDS

Refunds are not approved for this program.

 

RENTAL VEHICLES

Dealers are pre-approved for up to 14 days for a comparable rental vehicle if the inspection results determine the high voltage lower battery must be shipped to Piston Group for repair.  Follow Extended Service Plan (ESP) guidelines for dollar amounts.  Rentals will only be reimbursed for the days the vehicle is at the dealership for battery repair.  Prior approval for more than 14 rental days is required from the SSSC via the SSSC Web Contact Site.

CERTAIN 2012-2016 MODEL YEAR FOCUS ELECTRIC VEHICLES — HIGH VOLTAGE LOWER BATTERY CONNECTOR CORROSION

 

OVERVIEW

In the affected vehicles, corrosion on the high voltage lower battery connector may cause deformation of the connector allowing water ingress. Water ingress into the high voltage lower battery could result in a high voltage circuit isolation fault with a “Stop Safely Now” message displayed in the message center. If this occurs, the vehicle may not restart once it has been shut off. Dealers are to remove the high voltage lower battery from the vehicle, clean and inspect the high voltage connector, apply corrosion protection, install a protective shield and reinstall the high voltage lower battery in the vehicle.

NOTE: The high voltage lower battery in some vehicles may require shipment to a specialized facility to complete repairs.

Apply Corrosion Protection – (If No Connector Damage Present) – Page 5.
Battery Repair Process – (If Connector Damage Present) – Page 6.
High Voltage Lower Battery Connector Shield Installation – (All Vehicles) – Page 7.

WARNING: Service of the high voltage system on this vehicle is restricted to qualified personnel. The required qualifications vary by region. Always observe local laws and legislative directives regarding electric vehicle service. Failure to follow this instruction may result in serious personal injury or death.

WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a highvoltage symbol. Failure to follow these instructions may result in serious personal injury or death.

WARNING: Never install the service disconnect plug when a high-voltage service cover is removed. Always install the cover prior to connecting the service disconnect plug. The cover prevents inadvertent contact with the high voltage which is present at several points under the cover. Failure to follow these instructions may result in serious personal injury or death.

WARNING: Disconnect the 12 volt battery before servicing the direct current to alternating current (DC-AC) inverter or alternating current (AC) powerpoint to prevent the risk of high voltage shock. Failure to follow this instruction may result in serious personal injury.

Anywhere, USA 12345

 

Your Vehicle Identification Number (VIN):  12345678901234567

At FordeBay logo 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?

“Stop Safely Now”

“Stop Safely Now”

On your vehicle, it may be possible for corrosion on the high voltage lower battery connector to cause deformation of the connector allowing water intrusion.  Water intrusion into the high voltage lower battery could result in a circuit isolation fault that will cause a “Stop Safely Now” message to display in the message center.  If this occurs, you may not be able to restart your vehicle after it has been shut off.
What will FordeBay logo and your dealer do?In the interest of customer satisfaction, FordeBay logo Motor Company has authorized your dealer to inspect the high voltage lower battery connector and service as required, and then install a protective shield free of charge (parts and labor) under the terms of this program.

This Customer Satisfaction Program will be in effect until May 31, 2017 regardless of mileage.  Coverage is automatically transferred to subsequent owners.

How long will it take?The time needed for this repair is usually less than one-half day.  However, depending on the condition of the high voltage lower battery connector, your dealer may need your vehicle for up to two weeks to complete repairs.
What should you do?Please call your dealer without delay and request a service date for Customer Satisfaction Program 16B02.  Provide your dealer with your VIN, which is provided above, and request that your dealer order parts to repair your vehicle.

If you do not already have a servicing dealer, you can access www.Fordowner.com for dealer addresses, maps, and driving instructions.

FordeBay logo Motor Company wants you to have this service action completed on your vehicle.  The vehicle owner is responsible for making arrangements to have the work completed.

Do you need a rental vehicle?If your dealer determines that the high voltage lower battery connector is damaged, 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.
