1999 Mercury Cougar - right fuel tank strap failure. While traveling at highway speed, I suddenly heard a noise of something metallic slapping against the underside of the vehicle. After pulling over to investigate, I discovered that the right side fuel tank strap had completely corroded thru and had broken, allowing the fuel tank to drop down slightly on the passenger side. Once I was able to jack up the car to examine, I discovered that the coating on the metal strap had cracked off and that the metal strap was corroded so badly that the metal strap had torn from the weight of the fuel tank, allowing the strap to drop to the pavement. I replaced the strap with a universal replacement strap because I was told that the item would be a special order item and that I could not be guaranteed as to when it would be received. To prevent corrosion of the replacement strap, I primed and painted it with a rust inhibiting paint. I fear that if I had backed up while the strap had been broken (if I had been unaware of the condition) that the strap could have caught on the pavement and been forced up into the gas tank, possibly puncturing it, or that the gas tank could have broken the remaining strap and ripped from the undercarriage of the vehicle, resulting in a potential fire condition. It concerns me that automakers are not required to use a stainless grade (non-corroding) material for critical items such as critical suspension components, brake lines, or in this case, fuel system related components, such as tank support straps. I have never heard of a car of this age having this type of problem but found thru my search online that failure of the right fuel tank strap seems to be a bit too common on the 1999+ Mercury Cougar.

I've got a repeatable failure that happens when I make a left turn or go up an incline while I have less than a quarter of a tank of gas in my vehicle. The car will lose power and start to stutter, and has completely stalled a couple times. I haven't had any parts replaced yet, but I found other people with this problem and an extended coverage program offered by the manufacturer that they say doesn't apply to my vehicle. This has also been NHTSA campaign id as well. According to the emails with customer service the program was for cars manufactured May 25, 1999 through November 30, 2001. My car was manufactured on May 24, 1999. I questioned if the one day difference in manufacture could actually exclude my vehicle, if my vehicle could actually be affected, and whether there was some way to tell if the affected part was installed in my vehicle (possibly by part number or serial number of the installed part). There are apparently at least several different parts (the pre extended program part, the bad part being replaced during the program, and the one replacing the bad part. I have requested but not been given a way to tell the difference between the different parts.

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.

There is recall on Mercury Cougar 1999 V6 for a fuel filter that may cause hesitation, stalling, surging. Over fifty times has this occurred nearly causing serious accidents over five times. The car has been given a "tune up" to eliminate that as the cause. The only other cause could be the fuel filter which has been recalled as per recall 04V421000 NHTSA. I have contacted Ford and Ford dealerships and they refuse to deal with the problem. If this has happened on other vehicles then it is the cause on this vehicle whether they want to admit to that or not. This needs to be fixed before someone gets seriously injured or killed.

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.

1999 Mercury Cougar engine hesitates, losses power and bucks when attempting to accelerate. The consumer took the vehicle to the dealer after having the vehicle for 4 days, they still had not made a determination as to what was causing the engine to hesitate. The consumer took the vehicle to a local mechanic and was told the catalytic converter needed to be replaced, however after the replacement the problem continued. The consumer took it back to the mechanic and the inlet manifold runner control was replaced, but that did not resolve the problem either. The consumer took it back again and was told they had no clue as to what the problem was. After doing some research, the consumer came across a bulletin which described the problem he was experiencing and a resolution, which was a defect in the fuel delivery module. The consumer discovered the vehicle identification number was not included in the program.

When making a left hand turn and a half a tank of fuel or below, the engine misfires and almost stalls out, this presents a hazard when making a left-hand turn with oncoming traffic coming. The fuel system has been checked and seems to be operating fine.
