general problems of the 2002 Mercury Grand Marquis

For sometime now the headlights on my 2002 Mercury Grand Marquis appear to fade or dim soon after turning them on; giving the impression they are losing power and about to fail. I live in the mountains and am very familiar with each and every turn I see on the roads I travel. You see that is the matter of fact- if my headlights failed; I would not see the turn possibly a fatal fact.

The car has 87934 miles on it. When driving over 50 miles a hour it jerks and shakes the check emgine light will start flashing the coolant loght comes on then dies but will start right back up. Then coolant levels are fine. The license plate light does not work replaced bulbs and fuses.

The vehicle was taken to an independent mechanic where it was diagnosed that the lcm module needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 6,000. Ss.
