1993 Mercury Cougar Problems

What owners report

Owners of this model year most often describe engine cooling problems, particularly head gasket failure on the 3.8L V6, which complaints say typically appears as coolant loss, overheating, white exhaust smoke and rough running. Headlight flickering and going out is the other frequently reported problem, and many owners note their vehicle was not covered by campaigns addressing similar symptoms. Most reports come in at higher mileages, though owners mention failures anywhere from roughly 50,000 to 165,000 miles.

1. 1
   Engine cooling

   Head gasket failure on 3.8L V6

   • 86 complaints (44%)
   • median 105,850 mi at 11.1 yrs old (5 state mileage, few)
   • owner-quoted repair $1,170 (median of 10 quotes)
   • filed 1998–2004

   Owners describe coolant loss, overheating, rough idle, white or gray smoke from the exhaust, and a sweet smell under the hood, which mechanics attributed to a failed head gasket. Several say the repair cost roughly $1,000 to $1,700 out of pocket, and some report repeat failures after an initial replacement. Complaints note that extended warranty or service programs applied to later model years with the same engine but not to this one, and dealers generally told owners the work was outside warranty. Reported across a wide range, from about 50,000 to 164,000 miles, with many complaints between 60,000 and 120,000 miles.

   What to check: Look for coolant residue, milky oil, white exhaust smoke and a sweet smell, and ask whether the head gasket has been replaced and at what mileage. A coolant pressure test and a check of the coolant expansion tank can help before purchase.

   2 excerpts from owner complaints in NHTSA records

   “My 1993 Mercury Cougar xr7 has blown a head gasket twice (one at 80,000 miles and another at 120,000 miles.) and after searching the internet endlessly I have found many people like myself that had the same problem on the same make and model of vehicle. This is an outrage to myself and many other owners of this type of vehicle and I hope that you can do something to try and correct this problem.”

   NHTSA complaint #10047283, filed 2003-11, 120,000 miles

   “Head gasket blew at 67,000 miles , anti freeze was getting into engine. Reported to dealer who said it was no longer under warranty. That it was my responsibility and a two to three thousand dollar repair. I took the car to an independent garage and had the heads reworked and head gasket replaced. It cost me $1000.00 out of my pocket.”

   Exterior lighting

   Headlights flicker or go out

   • 15 complaints (8%)
   • median 120,000 mi at 12.2 yrs old (7 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1998–2017

   Complaints describe headlights flickering, dimming or shutting off for seconds at a time while driving, sometimes returning after the switch is jiggled. Several owners mention the problem being worse in hot weather or with high beams, and some report melted or scorched wiring and smoke from the dash area. Dealers often replaced the headlight switch, and a number of owners say they were told their vehicle was not included in the headlight switch campaign. Reported from roughly 4,000 to over 189,000 miles on the odometer, with several complaints noting the problem appears in warm ambient temperatures.

   Recall 99V275000

   What to check: Test the headlights and high beams at night and watch for flickering, and inspect the switch and connector area for heat damage or melted plastic. Ask whether the headlight switch or wiring harness has been replaced.

   2 excerpts from owner complaints in NHTSA records

   “The headlights start to flicker, flash on and off, when the ambient temperature rises above about 90 degrees. These symptoms are quite similar to those described by recall 99v275000, but my car does not have fog lights, so it does not qualify. This especially happens, when I am using my brights (high beams).”

   NHTSA complaint #731646, filed 2000-09

   “I was driving home going down a country road and my headlights quit working. I almost wrecked,and I almost lost control of my vehicle. I ended up driving it home with nothing but parking lights on which was a good half hour journey.”

   Body and structure

   Door hinges fail and doors sag

   Mentioned in 4 of 60 sampled complaints

   Owners report door hinges, especially on the passenger side, failing so the door becomes hard to open or close or sags on its hinges. In some complaints the repair was sent to a body shop at the owner's expense, and a few connect the hinge problem with the automatic seat belt jamming in the door frame. Reported on older, higher-mileage vehicles; complaints do not give a consistent mileage figure.

   What to check: Open and close both doors fully and listen for grinding or popping, and check that each door lines up with the body and latches without being lifted.

   “I have been trapped so to speak in my car and had to manually remove the seat belt- I can see this being a very serious problem I have attempted to have it taken care of but have to return to the dealer that did the repairs - in sayre , pa. -- they also replaced the hinges on the driver's side door.”

   NHTSA complaint #706760, filed 1999-05

   “The driver's seat belt failed to unlock. The auto shoulder belt did not move and interrupts the ability to maneuver the steering wheel. The driver door molding did would not stay in place. The driver door has to be pulled up in order to shut. Scc”

   Seat belts

   Automatic seat belt sticks or will not release

   Mentioned in 4 of 60 sampled complaints

   Complaints describe the motorized shoulder belt sticking in the closed position or failing to unlock, which owners say keeps them from getting out of the car or limits movement behind the wheel. Some say the belt did not lock during a collision, and dealers were contacted in several cases. Mileage is not consistently reported in these complaints; several involve cars that were already well used.

   What to check: With the car running, let the shoulder belt run its full travel several times and confirm it releases and retracts smoothly, and check that the lap belt locks when pulled sharply.

   An excerpt from owner complaints in NHTSA records

   “Consumer stated the driver side motor belt would intermittently lock up/stick in the closed position and would not allow driver to get out. Dealer notified.”

   NHTSA complaint #8004804, filed 2002-02
5. 5
   Brakes

   Excessive front brake and rotor wear

   • 13 complaints (7%)
   • typically at 4.5 yrs old
   • filed 1995–2001

   Owners describe repeated front brake work, with rotors replaced more than once and pads needing replacement at short intervals, along with ABS concerns. One complaint says the dealer considered the wear normal for the vehicle, and another owner reported the brakes not stopping the car during an unintended acceleration event. Complaints do not give consistent mileage figures; reports describe the problem continuing over years of ownership.

   What to check: Ask for brake service records, check rotor thickness and pad life, and test the brakes on a quiet road for pulsation or pulling.

   NHTSA complaint #721015, filed 2000-04

   “Ongoing problem with ABS/ front brake wearing excessively. Rotors replaced on three occasions, and brake pads have to be replaced every 10,ooo miles. Dealer notified, and informed consumer that was normal for this vehicle. Consumer seeking help from NHTSA, and believes this is a manufacturer's defect.”

   NHTSA complaint #837784, filed 1999-05

Buying note. This model year is old enough that condition and maintenance history matter more than anything else, so have a mechanic check for head gasket trouble and coolant loss before buying. Also verify headlight switch operation, door hinges and seat belt movement, and confirm whether any open recalls apply to the specific vehicle.
