  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.

  Risk: 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.

   I recently purchase 2010 Mercury Mariner. There is a few errors appearing on the screen in front of the steering wheel. One of the error is "CHECK FUEL LINES." It also has an error about the tire pressure sensor. It also rides roughly, but the wheels are like new, so it feels like the suspension or shocks have something wrong with them. Also, there is a lot of play in the steering wheel when driving it. When I went to check on the recalls in the system by putting in my VIN,…
