 Recently purchased 2012 Ford Explorer XLT.Have been very disappointed when driving it through mud, slush or snow.All the road debris (snow, slush, etc.) flows through the wheel well liners because of manufactured holes and inadequate linner size (too small).The door tracks and inside rails are a dirty mess after driving though any road debris.Ford says this is the way they designed and offer no fix.Dealer suggested we buy/install mud flaps.They have had other complaints about this condition.
