What owners report
Owners of this model year most often describe stalling and loss of power, frequently traced by mechanics to the fuel pump or fuel delivery module; many note the fuel-system recall on this vehicle and say the problem returned even after the recall repair. A second recurring theme is the sliding sunroof coming loose, jamming, or detaching while driving. Reports span a wide mileage range, from under 30,000 miles to well past 150,000.
- Fuel system
Stalling and loss of power (fuel pump / delivery module)
- 33 complaints (40%)
- median 55,900 mi at 5.8 yrs old (24 state mileage)
- 3 mention a crash, fire or injury
- filed 2002–2020
Complaints describe the engine quitting without warning at highway and city speeds, sometimes hesitating or refusing to accelerate when the pedal is pressed, and needing a restart or a tow. Several owners say a mechanic diagnosed a failed fuel pump or fuel delivery module. Some state the vehicle was covered by the fuel-system recall and that the stalling came back after the recall repair, while others say they were told their vehicle was not included. Reported from roughly 35,000 to over 150,000 miles, at various speeds including highway driving.
What to check: Ask whether the fuel-system recall work was done and whether the fuel pump or delivery module has been replaced since. Watch for hesitation or a stumble when accelerating, especially on inclines or with a low fuel level.

Sunroof jams, comes off track, or detaches while driving
- 10 complaints (12%)
- median 85,000 mi at 6.6 yrs old (9 state mileage, few)
- filed 2002–2017
Owners describe the metal sunroof binding or failing to close, sometimes opening by itself at speed, and in several cases the panel breaking free on one side or detaching while driving. Complaints mention broken plastic clips and track parts, and shops telling owners the whole sunroof assembly needs replacing. Some owners report that the dealer declined to cover the repair, and several point to a dedicated complaint website for this model. Mostly reported between about 25,000 and 125,000 miles; a few describe it happening at highway speed.
What to check: Open and close the sunroof several times and look for binding, gaps, broken clips, or a loose panel edge. Ask whether the sunroof assembly has been repaired or replaced.

“I opened my moonroof one day and it made a noise so I looked at it and it looked to be off track on the drivers side so we tried to shut it and it would not shut all the way so when it rained, it rained in my car. Finally took it to a repair shop and they said that the plastic clip was broke and had to force it closed so now when I go down the road it opens some and could eventually fly off, it is a distraction when I am driving because it makes noise and right now it is cold out and it rains in it. …”
NHTSA complaint #10149465, filed 2006-02, 55,000 miles“Went to open sun roof didn't work .

NHTSA complaint #10246532, filed 2008-10, 61,000 miles - Transmission and drivetrain
Automatic transmission harsh shifting or failure
- 12 complaints (15%)
- median 50,000 mi at 4.7 yrs old (7 state mileage, few)
- filed 2001–2020
Complaints describe hard or delayed shifts, the transmission slipping or feeling like it is in neutral, and overdrive dropping out. Several owners say the dealer could not reproduce the problem at first, and later reported that the transmission needed replacement at relatively low mileage. One owner says the dealer questioned how the car was driven. Mostly reported between about 38,000 and 65,000 miles, with some at higher mileage.
What to check: Test drive from a cold start and note any hard or delayed shifts, slipping, or failure to engage a gear. Ask whether the transmission has been serviced or replaced, and whether PCM programming was performed.

“2001 Mercury Cougar. Since I have owned this car I have replace the engine at 65,000 miles, left front wheel bearing at 70,000 miles, right front wheel bearing is on its way out at 100,000 miles along with a plugged catalytic converter, and transmission slippage. A/c also failed at 115,000 miles.”
NHTSA complaint #10112067, filed 2005-02, 67,000 miles“Bought car brand new in september 2001. Automatic transmission needs replacement at 43,000 miles (june 2005). No recourse as warranty only covered me for 3 years/36,000 miles. This is too soon for a transmission to fail. Although the car is automatic, I could feel the car lose power as it shifted automatically from 1st gear into 2nd gear. Took the card to ford dealer who told me it would cost $3,000 to fix. I am appalled!”
NHTSA complaint #10125354, filed 2005-06, 43,000 miles - Electrical system
Electrical faults: stalling, no-start, battery light
- 8 complaints (10%)
- median 129,000 mi at 13.6 yrs old (7 state mileage, few)
- 3 mention a crash, fire or injury
- filed 2003–2020
Owners describe intermittent no-starts, stalling while driving, the battery warning light coming on, flickering gauges, and blown fuses or headlight wiring. Some report an alternator failure just past warranty, and one describes wiring near the starter burning. Several say parts were replaced but the problem returned. Reported from around 36,000 to over 170,000 miles, across a wide range of ages.
What to check: Check that the battery light goes out after start-up and that all gauges read normally. Ask about alternator, battery, and wiring repairs, and look for brittle or repaired wiring near the headlights and starter.

“Just over 36,000 miles, the alternator completely failed leaving myself and a passenger stranded more than 50 miles away from home. Due to the fact that the warranty expired at 36,000 miles the local dealerships all refused to assist me with this matter forcing me to pay to replace the alternator. Furthermore, I was informed by several mechanics that a reasonable time estimate on an alternator is 100,000 miles.”
NHTSA complaint #10023353, filed 2003-06, 36,900 miles“The vehicle stalled while driving. The vehicle was started by popping the clutch. The consumer took the vehicle to the dealer, who stated that the problem was the wiring around the starter burning. Please provide any further information.”

- filed 2002–2020

What to check: Check coolant level and look for leaks or a sweet smell after a drive, and listen for knocking. Ask whether the water pump, radiator, or engine has been replaced.

NHTSA complaint #10197835, filed 2007-07, 75,000 miles
Buying note. Have a mechanic check the fuel pump and delivery module and confirm the status of the fuel-system recall, and test the sunroof and transmission carefully on a drive. Service records showing recent fuel, cooling, and electrical work are worth asking for on a car of this age.
