Recalls
Ford Motor Company (Ford) is recalling certain model year 2001-2008 Ford Escape and Mercury Mariner vehicles manufactured March 31, 2001, to September 1, 2009. The affected vehicles are equipped with either a 2.3L or 3.0L engine and have had their CD4E transmission replaced with remanufactured one that was rebuilt between June 11, 2015 through July 15, 2015. These service repair part transmissions have a shift lever bolt that may not be properly tightened. As a result, the shift control lever could disengage from the transmission without warning.
CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITHOUT SIDE AIR CURTAINS OR MOONROOFS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 201, "OCCUPANT PROTECTION IN INTERIOR IMPACT." DURING TESTING, THE FREE MOTION HEAD FORM REGISTERED A MEASUREMENT ABOVE THE PERMITTED LIMIT AT THE LEFT HAND A-PILLAR TRIM AREA.
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.

What Mercury told its dealers about the 2005 Mercury Mariner: known faults, fixes and updates.
| Bulletin | Summary |
|---|---|
| 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 |
