Bought car at dealer on 02/05/01 since then I've had to repair car on too many occasions. Here some of the repairs I've had to do on this car ever since I bought it. On 3/01: brakes, 10/01: dealership replaced battery and performed a recall,12/01: dealership replaced alternator, 05/02: brake pads, 04/04: water pump belt, 09/04: replaced batter, 10/11/04: replaced alternator and belt, 10/14/04: replaced positive battery terminal, 12/04: replaced radio, 02/06: replaced motor mount, 01/07:replaced battery, 02/07: replaced strut, 02/08: replaced shock absorber, 10/08: replaced battery, 04/09: replaced bearing, transmission & anchor engine mount and don't have the date but also had to replace the windshield wiper motor. These repairs are what I have in receipts yet for example I have replaced the motor mounts more than once. Currently the following areas of my vehicle do not function: the horn no longer works, cruise control is not functioning, the air conditioner no longer heats, & the brake light of my vehicle remained lit when the vehicle was on and now have failed to turn out (lamp socket is burnt).

I am the original owner of a 1999 mercury cougar automatic v6. I have never been in an accident with the vehicle, but continue to have mechanical problems. Like other 1999 ' 2000 mercury cougar owners I worry about the safety of driving a vehicle with more problems than can cost effectively be fixed. My list of broken items include the radio, power window regulator, o2 sensors, transmission at 59,000 miles, dashboard lights (low coolant and check engine), door/window leaky seal issues, engine misfire (decreased acceleration) and now my cruise control and turn signals do not work. Upon researching the recall for cruise control fires dealing with ford products I found that I am among other disgruntled cougar owners. Ford/mercury or ford technicians have not done a satisfactory job letting owners know of recalls that need attention. My latest concern is that my cougar might start on fire, per my complaint with ford; they see no threat with my cruise control issues and suggested I contact the federal safety agency with my complaint.

Dt: contact owns a 1999 mercury cougar. He has been looking on the internet and found recalls 04v4210000, 04v4210000,1v0320000, and 01v0310000 . He called the manufacturer, and they told him that this vehicle was not included in these recalls due to VIN although the contact's vehicle experienced the same failure as described in aforementioned recalls. While driving and accelerating the vehicle surged. He had not noticed this when the cruise control was on. But, noticed this immediately after purchasing the vehicle from an auction on 9-18-05. Also, the left rear tail lamp blew out three times in a short time frame. He bought the extended life bulbs, but they still blew out. However, some of the lights worked on the dashboard. . The engine light did not come on when he first started the vehicle. The contact noticed this 10-04-05.

I was heading home from the beach. I had my car on cruise control. A car was stopping ahead to turn into a housing development. I tried to push the brake to disengage the cruise control,but the cruise control did not disengage. I again hit the brake, harder this time, but the cruise control again did not disengage. With my foot on the brake I tried to swerve to miss the car in front of me. I ended up losing control of my car offroad and rolling the car into a ditch. I avoided any other cars or property, but my car was damaged heavily. I am still awaiting the assessment of the damage from my insurance company. My passenger and I both walked away, luckily we were wearing our seat belts.

When driving approx 50 MPH in 4th gear, car started to buck and chug, slowed down to 25, and stopped at stoplight, car chugged once and killed/stalled. Could not start, after 30 min car started but stalled after moving 10 feet, seemed as if car wasn't getting fuel. Dealership and first diagnostic test blamed fuel pump and they kindly replaced fuel pump for $100 deductible (car 5000 miles out of warranty). Yesterday, 4 days later, driving 70 MPH w/cruise control on, chugging/buckinh reoccured, and then car MPH started dropping fast, downshifted into 4th, pressed gas and nothing happened. Pulled over (car never killed) and put car in 1st gear and took off, 5 miles later it happened again (4 times total). Called dealership, blamed bad gas or water in the tank freezing in cold weather, both occurances happened at 1/4 tank of gas, added "heat" to remove any water, and will see what happens next time I am at 1/4 tank. Problem does not seem water/gas related problem is intermittent.

While traveling 30mph in traffic started applying brakes to slow down, had no brakes, and vehicle kept going. Brake pedal was almost to the floor. Also, cruise control had failed. Stopped vehicle and had it towed to mechanic. Was informed that brake booster plunger, had worn out, causing non braking ability.

Cruise control will not disengage with a tap on the brake - it must be fully depressed.

The incident occurred twice. First time at 65mph. Cruise control was suspected as problem so it was disconnected. The second occurrence was on 5/7/99. Speed 30mph. In both cases, the acclerator suddenly went to the floor & the vehicle shot forward at a very high rate of speed. The only way to stop it was shutting down the engine.
