What owners report
Owners of this model year most often report coolant loss from a cracked plastic intake manifold, usually noticed as a low-coolant light, steam, or an antifreeze smell and sometimes leading to overheating and a tow. Brake rotor complaints and door latches that open while driving also appear repeatedly in the sampled complaints, along with separated tire tread on the original Firestone tires. Many reports arrive at moderate to high mileage, though the intake manifold and rotor reports include vehicles well under 50,000 miles.
- Engine cooling
Cracked plastic intake manifold / coolant leak
- 14 complaints (23%)
- median 92,402 mi at 9.0 yrs old (8 state mileage, few)
- filed 1999–2011
Complaints describe coolant escaping from the front of the intake manifold, which owners say is made of composite material that cracks or tears. Symptoms owners mention include the low-coolant or check-engine light coming on, steam or white smoke from under the hood, an antifreeze smell, and coolant running onto the ground; several vehicles overheated or had to be towed, and some shops replaced the manifold, sometimes with an updated part. A few complaints note that the part was hard to find and that a revised version uses a different coolant crossover design. Reported from about 36,000 to 146,000 miles, in some cases on low-mileage vehicles stored much of the year; several owners mention hot climates.
What to check: Look for coolant residue, crust, or staining along the front of the intake manifold and ask whether the manifold has been replaced and with which version. Check the coolant level and watch for a low-coolant light or sweet smell after a drive.
2 excerpts from owner complaints in NHTSA records
“While driving my 1996 Cougar this past september, which has only 40,360 miles on it and is stored most of the year for the purposes of collecting and preserving the vehicle indefinitely, at low speeds I noticed the obvious sign of coolant and the smell of coolant coming from up under the hood. I then shut the vehicle down right away and discovered coolant running onto the ground below. …”
NHTSA complaint #10213808, filed 2008-01, 40,359 miles“I just purchased vehicle from used car lot. During my 3 mile trip home the car over heated and water vapor was coming in through air conditioning vents. When I stopped at my home, I could see steam coming from inside engine. When I opened the hood, I found that there was crack in a plastic part coming directly off of the engine block to a coolant hose. I went to several auto parts stores to identify the part and found it was a crack in the intake manifold water cross-over jacket causing coolant leak. …”
NHTSA complaint #10095591, filed 2004-10, 95,000 miles - Brakes
Front brake rotors warp and vibrate
Mentioned in 4 of 42 sampled complaints
Owners describe steering wheel vibration and noise when braking, traced to warped or rusted rotors; some report the front rotors were resurfaced repeatedly and eventually replaced, and one owner says rear rotors also needed cutting. One complaint describes the brakes failing and loss of control on dry, bumpy pavement. Front rotor work reported from roughly 10,000 to 48,000 miles, with the sampled brake complaints filed at low to moderate mileage.
What to check: During a test drive, brake firmly from highway speed and feel for pulsation through the pedal or steering wheel; ask for rotor service records and check rotor thickness and surface condition.
2 excerpts from owner complaints in NHTSA records
“The first time the front rotors had to be resurfaced the vehicle only had 10,000 miles on it, than it was resurfaced again and finally we had to have new rotors installed. The same problem started happening again causing the brakes to wear, rotors resurfaced again, than new tires in the front were wearing out of rounds, now this will be the fifth time we have to have the rotors repaired (resurfaced). The steering wheel vibrates terribly when applying the brakes due to this problem.”
NHTSA complaint #724029, filed 2000-06“The rear brake rotors need to be cut due to warping. This is the first problem with the rear brakes but, the front rotors have had to be cut down every 12,000-15,000 miles since new. At 48,000 miles the front rotors could not be cut any more and needed replaced. They were cut three times before being replaced. I had a similar problem with a 1989 Mercury Cougar and Mercury did find a problem eith the rotors being to thin. After being replaced I never had another problem with them for over 70,000 miles. …”
NHTSA complaint #706802, filed 1999-05 - Tires
Tire tread separation and blowouts
Mentioned in 4 of 42 sampled complaints
Complaints describe tread separating from the tire at highway speed, sidewall blowouts, and damage to the wheel well and fender afterward. One owner reports the tires had been checked for pressure beforehand and was told by the tire representative that the tire had run low on pressure. Reported on vehicles with the original tires, often at highway speeds; mileage was not given in most of these complaints.
What to check: Check the age and condition of the tires, including sidewalls and tread for cracking or separation, and confirm pressures; tires over six years old are worth replacing regardless of tread.
2 excerpts from owner complaints in NHTSA records
“About a month after purchasing the car, I had a flat on the front passenger side tire. We took the car to discount tires who told us that the tire on the back drivers side was separating and had to be replaced. They refused to fix the flat until we replaced the tire due to safety. We bought a replacement tire from discount tires and had it placed on the front drivers side. About two weeks later my son was driving the car on one of our loops, at the posted speedlimit of 70 MPH, when the rear passenger side tire shredded and blew out. …”
NHTSA complaint #727460, filed 2000-08“Tire blew out on city street going approx 35mph. Tire pressure was checked on 5-28-98 and also 9-2-98 by ford dealer. Have info on service tickets. Firestone rep said tire had been driven with low pressure and also on glass. Sidewall blew out. This person was not worth talking to. Purchased another brand and discarded carcass. ( DOT number: tire size: p215 70r/1 )”
NHTSA complaint #730191, filed 2000-09
Buying note. On this model year, the intake manifold and door latches are the items most worth confirming by inspection and by campaign history, since both appear repeatedly in owner reports; brake and tire condition are simple to check on a test drive and during a walk-around. Records showing whether the latch campaign and any manifold replacement were done are useful to request from the seller.
Summary written with AI from a sample of 42 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
