Engine failure due to a defective plastic engine intake manifold. 2000 Mercury Grand Marquis began to hesitate; the dealer said it was caused by a defective nylon intake manifold, and they would not cover the cost of repairs. Ford has had many complaints on this defect.

2000 Mercury Grand Marquis engine shut down causing consumer to lose power brakes and steering. This was caused by a short in spark plug. The short occurred in the spark plug on the #4 cylinder. This confused the power control module with signals it was receiving from the engine and tried to compensate which affected other systems and a sort of chain reaction occurred.

Vehicle was going about 35 mph when all of a sudden it started shaking. Then, lost its traction control, and caused the lights in the dashboard to turn off. This eventually led the engine to shut off, and the driver lost steering. Taken to dealer for a checkup, but the results showed that the cause was undetermined. Car shuddered, followed by engine shut down resulting in loss of power brakes and steering.
