One problem related to rear suspension springs has been reported for the 1999 Ford Contour. The most recently reported issues are listed below.
1999 v6 Contour se. Rh rear spring made by visteon broke from corrosion @ 87k miles. Lh rear spring covered with rust visteon is also maker of front springs that had recall on 95-97my front springs. Poor spring coating design incl. Iron phosphate. Ignition switch failure at 75k miles. Had to be replaced. Top of dashboard was recalled with a kit. Kit did not fix problem -- excessive rattles still exist. I understand that was the intent of recall & Ford has no additional kits or plans to replace faulty recall. Kit was replaced around 60k miles. Faulty dpfe sensor on this duratec engine. Dealer told me replacement sensors had a re-design that did not have exposed area that constantly triggers check engine light. Original sensors get contamination and will trigger the check light continuously. Ford did not recall and only replaced if complaints under warranty. I noticed problem around 60000 miles.
