“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. …”
NHTSA complaint #10340715, filed 2010-06, 99,750 miles“The car stalled in the middle of the street and engine could not be started. It had to be towed in to the nearest dealership. Diagnosis: fuel pump failure. Cost: $500. Two weeks later I found out that Mercury had a recall on fuel pumps, however my VIN number was not included in the recall. I suppose it's just a big coincidence that my car experienced the same exact symptoms and the fuel pump failed at the same time as the recall. Mercury to this date has not reimbursed me the $500.”
NHTSA complaint #10078282, filed 2004-06, 53,555 miles“I was commuting to work in mountainous terrain and while traveling uphill, the car lost power and then the engine quit completely. I was barely able to roll the car out of the highway before another vehicle approached the blind curve from my rear and swerved to avoid the broken down car and myself. I conducted an internet search after finally getting the car restarted and returning to home that evening and discovered that ford motor co. Had initiated a program to alleviate the symptoms the car was experiencing. …”
NHTSA complaint #10144753, filed 2005-12, 165,600 miles“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. …”
NHTSA complaint #10284562, filed 2009-09, 50,000 miles“I am the owner of a 1999 Mercury Cougar. I purchased the vechicle new and have maintained all service requirements. At this point, the vechicle still has less than 45,000 miles (I do not drive all that much). However, since purchasing this car I have had to replace twice the alternator and battery, all the brakes, tires, and now the fuel pump has gone out. I understand that there is a recall on the fuel pumps, so I contacted ford, but they informed me that my Cougar is not in among those on the list. However, my car has the exact symptoms that are listed by ford; it stalls and will not run. …”
