The NHTSA is ending an investigation into allegations of electronic throttle failure in Ford and Mercury vehicles. Instead, Ford will be conducting a special Customer Satisfaction Program (CSP) in which they will be contacting owners to take their vehicles to a manufacturer approved dealership to update the power-train calibration software to improve vehicle performance. Ford will also extend their power-train warranty coverage for up to 10 years of service or 150,000 miles.
The vehicles involved in this investigation include:
- 2009-2012 Ford Escape
- 2010-2013 Ford Fusion
- 2009-2011 Mercury Mariner
- 2010-2011 Mercury Milan
During the investigation, Ford found that some vehicles equipped with 2.5L and 3.0L engines could develop a high resistance buildup on the commutator, resulting in intermittent electrical connectivity and reduced engine power. When this condition occurs, the Malfunction Indicator Lamp (MIL) or Wrench light will illuminate and the vehicle may enter a limited limp home mode. In this mode, engine power and vehicle speed are reduced, while full function of the power steering, power braking, lighting, and climate control systems are maintained.
All vehicles are eligible for the program through January 31, 2015 regardless of mileage. The closing of this investigation does not constitute a finding that a safety-related defect does not exist.
