Paint is peeling, like there was never a primer put on the vehicle. Also the vehicle surges quite often. I have replaced the manifold spark plugs several times also coils. Is there a recall on Mercury paint that I can get some help with?

The contact owns a 2000 Mercury Grand Marquis. The contact stated the he smelled a burning odor. The contact looked at the temperature gauge which indicated that the vehicle had overheated. The vehicle was taken to an independent mechanic where the contact was informed the intake manifold was made of plastic and was leaking. The leak was sealed, but the contact was informed that the repair may not hold up for a long period of time. The failure mileage was 100,000 and the current mileage was 103,000. The VIN was unavailable.

Spark plug blew out of #8 cylinder without warning merging onto highway. If this happens on a different cylinder it could puncture the fuel rail; ultimately causing a fire from the ignition coil spark.

Air control valve failure. This item not covered by my 90,000 mile warranty. Why not" shop said an item that controls braking jammed causing the brakes in the front brakes not to retract after releasing pedal therefore destroying calipers pads & rotors. This item not covered by extended warranty either. Why not"

  • Automatic transmission

When the vehicle is started, an unusual noise occurs in engine, especially in the morning, then gradually gets louder/more frequent. One day in particular, the vehicle was parked(hot weather), and when the vehicle was started, the noise started again, and was extremely loud/distracting to others. The dealer cannot duplicate, stating that all the models sound this way and is the timing chain. Other problems are as followed: Radio static/window static-when the ignition is on(may be a loose wire, and when the brakes are applied, it engages the brake light switch. The consumer requests that the problem(s) are fixed before the warranty expires. Scc
