- Problem
- 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.
- Risk
- If the shift lever disengages from the transmission, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the gear selection indicator may show that the transmission is in the "PARK" position, but the vehicle transmission may not actually be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
- Fix
- Ford will notify owners, and dealers will inspect the transmissions and either tighten the manual shift lever bolt or replace the manual shift lever assembly. These repairs will be performed free of charge. The recall began on October 23, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S28.

NHTSA campaign 14V526000 · 70,209 vehicles
- Problem
- Ford Motor Company (Ford) is recalling certain model year 2005-2008 Ford Escape hybrid electric vehicles manufactured October 13, 2003, to June 20, 2008, and 2006-2008 Mercury Mariner hybrid electric vehicles manufactured June 10, 2005, to June 20, 2008. The coolant pump for the hybrid system may fail resulting in the hybrid electronics overheating.
- Risk
- If the hybrid electronics system overheats, it may shut down the powertrain, resulting in a stall-like condition, increasing the risk of a crash.
- Fix
- Ford will notify owners, and dealers will inspect and replace the original Motor Electronics Coolant (MEC) Pump with an improved brushless pump, free of charge. The recall is expected to begin on October 27, 2014. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 14S19.
