Recall of brake pressure control. Ford service center states repair was done on 12-19-2000, but there is no records to confirm. In addition, the fuel system recall, Ford states that there isn't one on my vehicle, however, my vechicle displays the same symptoms described under recall 04v421000 and the continuous check engine light. I have had all sensors repaired that came up in engine diagnostic testing . According to last test done, reads fuel is running lean but can't repair because no code appears for that to show where problem lies. I have had fuel system flushed to help remedy problem. Still having issues.

4 Check Engine Light On problem

Failure Date: 06/01/2006

I would like to complain about my Cougar. I cannot pass the IL. Emissions tests, due to the fact that the O2 sensors are defective. My engine light is constantly on. I have had my car serviced for the engine light, alone, 8 different times. Eight! this is incredible. Also, my car makes a loud screeching noise when I attempt to start it. -if it starts at all. - I have had my starter replaced twice. Twice!!! this car is a lemon. Nothing but a lemon. How could Mercury sale such crap and get away with it. My drivers' license will be suspended because I cannot pass the emissions test. If I can even get my car to the testing facility. I have had the alternator changed, the fuel pump, the electrical wiring changed, sunroof, turning signal, even the radio was defective. I sincerely hope that there is a class-action lawsuit against Mercury, because I will be the first one in line to sue.

5 Check Engine Light On problem

Failure Date: 02/27/2006

Since moving to texas in 2001 I have had repeated problems with the check engine light coming on. I have spent in excess of $5,000 trying to get this fixed. I just picked up my car again today after spending another $700+ to get the problem fixed. I only went approximately 3 miles when the light came on again. I am trying to find out what the problem is. I feel this is a recall item and would like something done concerning this problem. I have been told it was a weather issue, etc. It seems no one seems to know what the problem is. Help!!!!.

7 Check Engine Light On problem

Failure Date: 09/01/2005

I have had multiple problems since I purchased the car in 10/99. I have had the sun roof replaced once and now needs it again for the same reason; the track broke ($1000 to fix, $2000 if I go to the dealer). The ignition switch has been changed twice because it sticks (it need to be changed again). In 2/00 it started: whenever the car got cold, the car would either not turn on or would just shut down while I was driving. The car was brought to the dealer multiple times for the same problem. He changed numerous parts but was unable to resolve the issue, until a 2004 recall for something to do with the fuel system. About three years ago the engine light came on at which time the dealer replaced the catalytic converter. A few weeks later the engine light came on again at which time the dealer told me it was the head gasket. That, I had replaced by an independent mechanic and then still had to bring it back to the dealer to have the catalytic converter done a second time, and to have the computer reset to have the engine light shut off. Anytime I have work done on the car, even just maintenance, the check coolant light or the engine light comes on and I have to bring it to the dealer to have it shut off. In 9/05 the coolant light illuminated and a day later the engine light came on, I brought the car to an independent mechanic who changed the overflow tank because he believed it to be a bad sensor. After fixing that, the engine light would not go off as well as one of my brake lights. He did multiple tests and determined that it is something electrical, unfortunately he could not pinpoint the exact cause of the electrical problem. For some reason those lights have gone off but I expect them come back on soon.
