What Ford told its dealers about the 2010 Ford Flex: known faults, fixes and updates.
| Bulletin | Summary |
|---|---|
| 10254138 | All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership managemen |
| 10235153 | For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are |
| 10180428 | Some 2009-2020 Ford and Lincoln vehicles equipped with turbochargers may exhibit an oil leak from the turbocharger oil supply or return tubes, O-rings or 6.7L pedestal gasket. Although oil may collect on the turbocharger, it is very rare for a turbocharger to leak oil. To isolate the source of the leak, refer to Workshop Manual (WSM), Section 303-00 General Information > Diagnosis and Testing > Engine > Engine Oil Leaks - Fluorescent Oil Additive Method procedure. When an oil leak is present at a turbocharger oil supply or drain tube, remove the affected oil tube and inspect for damage, and re |
| 10164508 | Some 2010-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding. The portion of glass that is covered by the cowl or molding will not be affected by the acid. Hydrofluoric acid d |
| 10163573 | Some 2009-2017 Expedition/Navigator, 2009-2014 F-150/Mustang, 2008-2009 Sable, 2008-2019 Taurus/Flex/MKT, 2013-2019 Police Interceptor Sedan/Utility, and 2011-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs. Use pigtail harness se |
| 10160931 | On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop |

This may be due to a poor electrical connection at the blower motor speed control.

| 10152473 | For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. For all turbocharged engine applications, the turbocharger oil supply filter (6C683 gas engine/6L625 connector style or 6A968 diesel engine) must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter. |

| 10137131 | Some 2007-2016 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Police Interceptor Sedan/Explorer/Police Interceptor Utility vehicles equipped with AWD and built on or before 30-Jun-2016 may exhibit a propane or natural gas odor during idle or low speed driving. This may be due to break down of the power transfer unit (PTU) fluid caused by excessive heat. If the source of the odor is identified as originating from the PTU, an idler bearing repair kit is available to repair the PTU. Refer to the Workshop Manual (WSM), Section 308-07. If the PTU is determined to be repairable, utilize kit GB5Z-7P258-A and the i |

| 10127405 | Some vehicles may exhibit a no start condition with an illuminated malfunction indicator lamp (MIL) and a DTC P161A after PCM replacement. This may be due to the parameter reset procedure not being properly completed. To clear this DTC, use the Ford Integrated Diagnostic System (IDS) service tool or Ford J2534 Diagnostic Software, select - Toolbox - Body - Security - PATS Functions - Parameter Reset. Follow the on-screen instructions to complete the procedure. This procedure will transfer the existing Key ID information between the modules without the need of having 2 programmed PATS keys pres |
| 10109070 | The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer |
