AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.
Recalls
NHTSA recall #16V777000October 26, 2016329,265 vehicles affected
fuel system, gasoline: delivery: fuel pump
Ford Motor Company (Ford) is recalling certain model year 2010-2012 Ford Escape vehicles manufactured February 26, 2009, to April 29, 2012, and 2010-2011 Mercury Mariner vehicles manufactured February 25, 2009, to December 12, 2010. On vehicles with a 3.0L engine, the Fuel Delivery Module (FDM) may crack, causing a fuel leak.
A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy
Ford will notify owners, and dealers will replace the FDM flange with one that has a redesigned fuel supply port, free of charge. Remedy parts are currently unavailable. Interim notices were mailed to owners on December 13, 2016. Owners will receive a second notice when remedy parts become available. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S41.
NHTSA recall #14V284000May 29, 2014740,878 vehicles affected
steering: electric power assist system
Ford Motor Company (Ford) is recalling certain model year 2008-2011 Ford Escape and Mercury Mariner vehicles manufactured August 18, 2006, through September 11, 2010. The affected vehicles have a steering torque sensor that may not be able to properly detect driver steering input. As a result, the system could remove the Electric Power Steering (EPS) assist.
If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
Remedy
Ford will notify owners, and dealers will update the software for the power steering control module (PSCM) and the instrument cluster module, free of charge. If a vehicle shows a history of a loss of the torque sensor signal or fault codes relating to the PSCM when the vehicle is brought in for the recall remedy, the affected components will be replaced, free of charge. The recall began on July 18, 2014. Owners may contact Ford customer service at 1-800-392-3673. Ford's number for this recall is 14S05.
