Recalls for the 2000 Mercury Cougar: 5
The part numbers packaged with incorrect nuts are: K7147, K7329, K8683, and 104353. These parts were made for use on the various vehicles listed above. The nuts included in the packaging for these ball joint assemblies are missing the intended prevailing torque (Self-locking) feature.
Certain aftermarket brake hydraulic master cylinders sold as replacement brake cylinders for certain Ford, daimlerchrysler, and Jeep passenger vehicles. These brake cylinders were sold under the brand names of napa, raybestos, aimco, ac delco, carquest, bendix, and wagner. Loss of brake fluid can lead to a decrease in brake line pressure and an increase in stopping distance, which can result in a vehicle crash.
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. 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.
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. The short could potentially result in a fire, stalling, or a no-start condition.
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. 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.
