1996 Mercury Mystique Problems

What owners report

Owners of this model year most often describe electrical trouble: melting or burned wiring, blown fuses, lights that stay on or fail, and in some cases smoke or fire. The other frequent themes are engine cooling and head gasket failures, automatic transmission failures, power window problems, and fuel leaks at the filler neck. Many reports come at higher mileage, but several owners describe failures well under 100,000 miles.

1. 1
   Electrical system

   Melting wiring harness, blown fuses and smoke

   • 32 complaints (17%)
   • median 96,500 mi at 10.9 yrs old (7 state mileage, few)
   • 10 mention a crash, fire or injury
   • filed 1998–2009

   Complaints describe wiring under the hood, under the dash or in the headliner overheating to the point that insulation melts and harnesses burn up, and fuses blow repeatedly. Some owners report the car stalling or dying, sometimes at speed on the freeway, and a few describe smoke or fire from the engine compartment or dash area. Several say they were told the repair is not covered, either because of mileage or because the VIN was not included in a campaign. Reports span the full life of the car, from a few years old to well past 100,000 miles, with several owners noting failures between roughly 60,000 and 140,000 miles.

   Recall 01V2300001 related service bulletin

   What to check: Look for discolored, brittle or repaired wiring under the hood, behind the dash and near the blower motor and fuse boxes, and ask whether the heater blower resistor and connector have been inspected or replaced.

   “The under hood wire harness burned up. This car has 89,000 miles and runs good. I heard there was a recall / TSB #( onp 99m03) on this car but ford will not honor it because the car is over 10 years old. I think ford should reimburse for repairs or buy back the car. This is a dangerous situation as the car will stall abruptly and lose power steering.”

   NHTSA complaint #10254653, filed 2009-01, 89,000 miles

   “Car has had increasing number of electrical problems...check engine light coming on. Mechanics couldn't find what was triggering it after replacing the oxygen sensors repeatedly. Other twitches (stalling, burned up turn signal module,) finally culminating in complete brake light and reverse light failure. Took the car back to my mechanics, who replaced the signal module, and showed me the burn marks on it. …”

   Electrical system

   Interior and instrument lights stay on or fail

   Mentioned in 6 of 60 sampled complaints

   Owners describe interior, dash and parking lights that come on by themselves and stay on, or that quit entirely. Some report a ticking or ringing noise like the turn signal running when the switch is off, smoke from the steering column when signaling, or a dead circuit that blows a fuse. Dealers are often described as unable to locate the cause. Mostly reported on cars that were a few years old, with complaint mileage ranging from moderate to roughly 138,000 miles.

   Recall 99V103000

   What to check: Check that dash, interior and exterior marker lights all work and that none stay lit with the car off; ask about prior turn signal module or headlight switch repairs.

   “Whenever vehicle was started, interior and instrument panel lights came on & remained on . Turn signal would constantly be ringing when signal switch was not in use. Took vehicle to dealership & informed mechanic of the problems. Mechanic indicated has not heard of the problem before, and did not do anything.”

   NHTSA complaint #857666, filed 2000-02

   “Took vehicle to a ford dealer for recall of engine cooling fan motor. They checked and said there was no problem, however a fuse was blown and they did replace the fuse. This tells me there must have been a problem for the fuse to need replacing. Approx. 3 weeks later, without any signs, was driving to work and the check engine soon light came on. Immediately afterwards the car stopped. The engine overheated and totally melted the engine components. The car had just been serviced. …”

   Engine cooling

   Engine overheating, head gasket and water pump failure

   • 15 complaints (8%)
   • median 98,512 mi at 7.8 yrs old (3 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1998–2004

   Complaints describe overheating that leads to warped heads and blown head gaskets, sometimes after the water pump impeller breaks apart. Owners report the check engine light coming on, the engine stalling or running rough, and in one case the cooling fan failing after a recall inspection. Repair bills described include head work, gaskets and cooling system parts. Reports cluster from about 58,000 to 120,000 miles, with a few very early failures.

   Recall 00V367000

   What to check: Check coolant level and condition, look for residue around the head gasket seam, and ask whether the water pump and cooling fan have been replaced.

   “Filler hose leaks badly when tank is filled. Car diagonosed by mel clayton ford of phoenix, arizona with filler hose and vent valve need to be replaced, possibly needing a new fuel tank as well. Car also runs hot all the time (ford unable to diagnose the problem)”

   NHTSA complaint #10070567, filed 2004-01, 98,512 miles

   “Head gasket failure. Coolant system failure. Check engine light came on without warning, flashed and constant. I guess what they say about ford is right found on road dead fix or repair daily ouch”

   NHTSA complaint #10069479, filed 2004-01, 90,500 miles

   Transmission and drivetrain

   Automatic transmission stops driving or shifts oddly

   • 16 complaints (9%)
   • median 61,900 mi at 11.8 yrs old (3 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1998–2007

   Owners report the transmission failing to move the car in drive or reverse while the engine still runs, or hesitating before engaging and then dropping speed. Several describe the overdrive light coming on, hard shifting, or a whine before the car stalled. Complaints say shops recommended replacement or a full rebuild, sometimes at relatively low mileage. Described from about 55,000 miles upward, with several reports near or above 100,000 miles.

   Recall 98V233000

   What to check: Test drive from cold and check that drive and reverse engage promptly, and ask for transmission service records; also confirm the gear indicator matches the actual gear.

   “I purchased my Mercury Mystique new in november of 1996. I have always driven the car very easy, I don't even get on the expressway very often. At around 45,000 miles, I had the transmission serviced, which the owners manual doesn't even mention. Now, with only 55k miles, the transmission has failed and needs a total rebuild! Although the car is nearly 9 years old, at 55,000 miles the transmission failing is not acceptable. There has to be some kind of flaw in the design for it to do this.”

   NHTSA complaint #10136054, filed 2005-09, 56,000 miles

   “The forward gears on my transmission have ceased to work. Now I'm being told that the transmission needs to be replaced. I find it kind of weird that a 96 needs a new transmission already.”

   Visibility (wipers, defrost, mirrors)

   Power window motors and regulators failing

   Mentioned in 4 of 60 sampled complaints

   Owners describe windows that move slowly or need repeated button presses, then stop working entirely, often on the driver or passenger front door. Complaints mention motor or cable drive failure and corroded window switch panels. Dealers are described as saying the car was out of warranty or not covered by a recall. Reported at low to moderate mileage, in some cases around 40,000 miles and under.

   What to check: Operate every window several times and listen for slow travel or clicking; ask whether window motors or switch panels have been replaced.

   “My heater control knob for high,med,low only work in the low position. My rear brake light had a leak,allowing water to fill up and blow my light bulbs.there is a ticking noise in my dash as if my turn signals is running, but no flash on the indicators. When I signal to take turns it works fine but when not turning still makes clicking noise. Transmission went out in october 2000, I heard this is a common problem in my vehical.. Thank you for your time.”

   NHTSA complaint #740565, filed 2001-02

   “When trying to put the driver side window down, you have to keep pushing the button until it finally decides to go down. When putting it up it is the same way, but it takes forever to get it up. Sometimes you have to open the door or pull on the door and then it may go up and then again it may not. I have taken it to crane lincoln Mercury to get it looked at and in the process the rolled it down and could not get it back up. They told me they finally got the window up but the motor would not hold it up and it fell back down. …”

Buying note. On a car this age, the condition of the wiring and cooling system matters more than mileage. Have a mechanic inspect the harness, cooling system and transmission operation, and ask for records of any recall work or prior electrical repairs before purchase.
