NHTSA lists 3 safety recalls covering the 2000 Mercury Cougar. Open recalls don't stop you from selling or junking the car, but check your VIN at nhtsa.gov/recalls to see which apply to yours.
Fuel System, GasolineAug 2004 · NHTSA campaign 04V421000
On certain passenger vehicles, contamination of the filter in the fuel delivery module (fdm) can reduce, and eventually block, the flow of fuel to the engine.
Risk: This may cause engine hesitation, loss of power, surging, and other similar symptoms. Over time, the filter may become sufficiently blocked to cause the engine to stall, which could result in a crash.
Electrical SystemFeb 2001 · NHTSA campaign 01V031000
Vehicle description: passenger vehicles equipped with 2.5l v6 engines. The battery cable was misrouted and its attachment to the alternator cable was under-torqued. If misrouted, the cable could contact the power steering line and the insulation could wear, resulting in an electrical short.
Risk: The short could potentially result in a fire, stalling, or a no-start condition.
Service Brakes, HydraulicMar 2000 · NHTSA campaign 00V075000
Vehicle description: passenger vehicles not equipped with the anti-lock braking system (ABS). A pressure conscious reducing valve (pcrv) in the rear brakes may be subject to corrosion and result in malfunction, when operated in areas that use salt compounds on the roadway for de-icing or dust control.
Risk: If both pcrv's malfunction, vehicle handling could be adversely affected during braking as a result of the rear wheels locking, increasing the risk of a crash.
