2002 Mercury CougarAcceleration & cruise controlEngine & coolingFuel system

Since purchasing 2002 mercury cougar in january 2010 the vehicle hesitates, surges, and stalls at any rate of speed. Initially the problem was rare, then gradually occurred more frequently. This now happens at least weekly, sometimes several times per day. This issue has endangered me more times than I can currently recall. Replaced alternator, battery, egr valve and sensor, iac valve, and catalytic converter. The issue persists.

I'm having the same issue with my 2002 mercury cougar as everyone else, but when I put my vin number into the search, there are no recalls listed for it. I don't think that its right that my life be put in serious danger because of an apparent design issue. This car is losing all power and shutting down. It doesn't matter how fast you are going, it happens at all speeds. We thought the alternator was bad, had it replaced and the battery at the same time. The same day, the car lost all power again and died out...

going 60 mph on the highway. All the gauges start going crazy and the lights dim and eventually everything including the car just quits. Mercury/ford, needs to be responsible for this coffin that I'm trying to drive and fix the problem for me and everyone else for free. I've done some online research on this, and it seems like there are a ton of people with the same problem from years 99 to 02. *Tr

I was on my way to work and about one mile from my destination the engine just stopped. I let it sit about twenty minutes and it finally started again. This happened several days of shutting off while I was on the road driving.

I took it to a mechanic and...

he told me the computer needs to be replaced. The only place that could replace the computer was the dealer. I took it to the dealer and after being at the dealer for three days they said that the ignition need replacing. They replaced the ignition and after three more days there and while they were working on other repair parts that they said I needed done the engine shut off about two more times. On march 13, 2014 they told me that all repair work had been completed and the engine shutting off was solved. The total bill came to close to $3,000.00. I am planning on picking up the vehicle on monday, march 17, 2014 when I will have the money to pay them. I heard about cars engines shutting off while driving on the radio (wtop). I just wanted to report how my vehicle was having the same or similar problem. I am a bit nervous about driving this vehicle if this could possible happen again. The radio report was about gm vehicles I have a mercury and this happened to my car. *Tr

surging while at complete stops, and has been shutting off while at a stand still. We've tried fixing many things, but nothing seems to be fixing the issue. After doing extensive research, I have come to realize that many others are having the same issues. Can someone do something about this please?? Its clearly an on-going issue and is costing people lots of money. Her car is currently back at the dealership where we purchased the car, and is undergoing diagnostics. We were already told that her car was not included in the recall, and we will have to pay for even more work, out of pocket. Please help.. Why was it not included in the recall, seeing that it is having the same problems?! *Tr

1997 Mercury CougarEngine & coolingTransmission & drivetrain

My vehicles became totally disabled on a very busy highway with heavy after hours rush hour traffic. The manifold which is made of plastic broke were the coolant temperature sensor was built in, I also noticed that a few sparkplugs were flooded with coolant. I found out that there was a lawsuit on these vehicles but no one knew about it and only fleet vehicles were covered and not civilian vehicles. I wonder if there is any chance for me to seek a dealership and get reimbursed for these damages. *Tr
