I bought this car to replace my Chevrolet caprice(great car) on 719 07 this car has major issues that Ford motor company refuses to address. July 2011 fuel tank filler neck rusted causing a fire hazard dec20 11 rear axle control arm cracked causing car to sway Feb 2012 plastic intake cracked causing coolant to spray all over engine. Ford issued a recall for this I called the local Ford dealer about this they told me it expired so im stuck to repair the car myself front end parts not serviceable and wear out (no grease fitting to lube) this has been the worst car I have ever owned.
A spark was blown out of the cylinder head. The problem occurred 3 times (2010, 2014, 2014), each time a different cylinder. One of these times, it occurred to my wife 140 km away from home. I had to guess that it was a blown spark plug and instructed her to drive the car to toronto in this condition. Concern: aside from the costly repair, I am afraid to use the car on a long trip for fear that this will happen at a place where a repair is not available. I suspect that the Ford company has modified the engine along the way, considering the fact that on a previous model I had owned for a long time (1993 Grand Marquis), the problem had never occurred.
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?.
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.
