What owners report
Owners of the 1998 Lincoln Mark VIII describe a car that drives well when new but that develops a recurring set of mostly comfort- and parts-availability problems as it ages. The most common report is a failed climate-control blend door that leaves owners without heat or defrost, followed by daytime lighting complaints tied to discontinued HID headlamp parts. Several complaints are about components that are no longer produced, which makes repairs harder than the failure itself.
- Visibility (wipers, defrost, mirrors)
Climate blend door failure (no heat or defrost)
- 15 complaints (18%)
- median 64,049 mi at 7.0 yrs old (5 state mileage, few)
- owner-quoted repair $680 (median of 5 quotes)
- filed 2002–2016
Owners describe a broken plastic arm or actuator on the air blend door motor, after which the system sends only cold air or no air to the windshield. Complaints say the windshield fogs over in humid or cold weather despite the defroster being on, and that repairs require removing the dashboard, which several owners describe as expensive. Some say the dealer confirmed it is a familiar failure on this model. Reported across a wide mileage range, from roughly 23,000 to 88,000 miles, usually in cold, rainy or temperature-changing conditions.
What to check: With the engine warm, switch between defrost, heat and A/C and confirm the air actually changes temperature and direction. Ask whether the blend door actuator or arm has been replaced, and get any dash-removal repair estimate in writing.

“While driving down the road, because of the weather conditions, I noticed that the windshield was getting clouded over. Turned on my ha/c to defog the windshield but only cold air came out adding greatly to the windshield fogging. I was able to stop the car before running into opposite lanes of traffic since I couldn't see out the windshield. I got a cloth and wiped it clear to procede. …”
NHTSA complaint #769183, filed 2002-11“The blend door that controls the heat and air conditioning has stopped working and has rendered my heating / cooling system dysfunctional. This seems to be a widely known issue for this car (1998 Lincoln Mark Viii lsc) - it poses a dangerous and tangible threat to safety considering heat will not work to defrost the windows and front windshield.”
NHTSA complaint #10211874, filed 2007-12, 85,500 miles - Exterior lighting
HID headlamp failure and discontinued bulbs
- 7 complaints (8%)
- median 102,763 mi at 10.9 yrs old (4 state mileage, few)
- filed 2001–2016
Owners report that one or both HID low-beam lamps stop working, or that the assemblies cloud with condensation, and that the original bulb is no longer manufactured. Complaints describe parts-store and dealer searches that turn up nothing, used bulbs offered at high prices, and a dealer-supplied conversion kit as the suggested route. Some also mention dim output from a failed ballast before the lamp goes out entirely. Mostly reported on cars with well over 60,000 miles, including one at about 150,000 miles, often years after purchase.
What to check: Test both low beams and high beams after dark and look inside the lamp housings for moisture or haze. Ask whether a conversion kit has been fitted and whether spare bulbs or assemblies come with the car.

“I own a 1998 Lincoln Mark Viii. I have owned this car since 1999. Recently, one of the headlight lamps burned out. I attempted to buy a replacement bulb at several auto parts stores without success. I contacted the local Lincoln dealers and found that the bulb (sylvania 9500) is no longer manufactured. I also found that there is no stock of available bulbs in the united states except for used bulbs on e-bay. (for $199). …”
NHTSA complaint #10262952, filed 2009-03, 101,000 miles“Update to last complaint: the passenger side hid headlight has failed, no replacement except $1000 conversion kit. Have to drive with only brights on from now on. Danger to myself and those I'm passing, plus if the brights aren't on, then I have no headlights and could get pulled over. Passenger side ball joint/control arm broke while driving and tire fell off while driving in parking lot at work. After repair, hearing a bad creaking noise. …”
NHTSA complaint #10865064, filed 2016-05, 104,527 miles - Brakes
Brake pedal going to the floor
- 6 complaints (7%)
- median 74,095 mi at 12.8 yrs old (3 state mileage, few)
- filed 1999–2011
Owners describe the brake pedal sinking all the way down during normal or gradual stops, with much less braking than expected, and in some cases using the parking brake to stop. One detailed complaint links a stuck parking-brake release solenoid to overheated rear brakes, boiled fluid and a soft pedal. Complaints say dealers could not duplicate the problem or diagnose it, and at least one owner was told an ABS wheel sensor was no longer available. Reported from the first years of ownership through high mileage, including cars around 50,000 to 88,000 miles.
What to check: Check brake fluid level and pedal feel with the engine running, and ask for service records covering the ABS sensors, parking brake release and master cylinder.
2 excerpts from owner complaints in NHTSA records
“The front ABS speed sensor has failed on my 1998 Lincoln Mark Viii. The car currently has only 50k miles on it. These sensors have been discontinued by ford starting 2005. They are not interchangeable with any other vehicle and no automotive parts store carries them. Ford made close to 18,000 Lincoln Mark Viii in 1998, the ABS sensor is crucial in the proper operation of the ABS as well as the traction control, as it is right now there are no replacements available anywhere. …”
NHTSA complaint #10186930, filed 2007-04, 50,250 miles“The brakes can quit working after the automatic parking brake release solenoid fails to release the rear brakes when the transmission lever is moved out of park. The rear brakes will then overheat after several miles, which causes the brake fluid to eventually boil and be expelled from the master cylinder. The first symptom is that the brake pedal goes almost all the way to the floor and braking becomes erratic. Shortly thereafter, the braking system totally failed to stop the car due to lack of brake fluid in the master cylinder. …”
NHTSA complaint #10388611, filed 2011-03, 74,095 miles - Suspension
Front ball joint and control arm separation
- 8 complaints (10%)
- median 104,527 mi at 13.0 yrs old (5 state mileage, few)
- filed 1999–2016
Complaints describe the front suspension collapsing so the tire drops and the car falls onto the ground, sometimes at low speed and in one case on a second occurrence after a replacement part was fitted. Shops quoted in the complaints diagnosed broken ball joints and control arms. Other owners mention creaking or knocking from the front end afterward. Reported on higher-mileage cars, generally above 100,000 miles, during low-speed driving or over train tracks and rough pavement.
What to check: Have a shop inspect the front ball joints and control arms on a lift before purchase, and listen for creaks or clunks over bumps on a test drive.

“I've had this gem since 2010, bought with 30,000 miles...now has 104,000 miles. It was great until 2014. Where do I start? (1) no heat- broken blender door actuator...manually set it to the warm setting for the winter behind glove box. (2) driver's door handle snapped last year(replaced for $100)...and now this year the passenger side snapped. (3) doors are constantly ajar , alternating from one side to the other. …”
NHTSA complaint #10824162, filed 2016-02“The contact owns a 1998 Lincoln Mark Viii. The contact stated while driving approximately 15 MPH, the front driver's side tire separated from the vehicle, causing the vehicle to suddenly drop to the ground. The vehicle was towed to an independent mechanic, who stated the ball joint was broken. The mechanic replaced the ball joint with a master pro cp426. The contact experienced the failure a second time, but was able to pull over to the shoulder of the road. …”
NHTSA complaint #10384353, filed 2011-02, 127,000 miles
Buying note. Budget for climate-control and front-suspension work on this model year, and confirm that lighting, ABS and blend-door parts are obtainable before committing. A pre-purchase inspection covering the brakes, front ball joints, air suspension and defroster is worthwhile on a car of this age.

Example complaints
Visibility (wipers, defrost, mirrors): “Electronic temperature control failures prevents windshield clearing when internal to external tempertaure differential fogs the glass. Blend door fails on a significant number of Lincoln Mark Viii models. Mine happens to be a 1998. It's bound to lead to accidents”
NHTSA complaint #10075009, filed 2004-06, 65,639 milesExterior lighting: “1998 Lincoln mark vlll lsc (hid headlight bulb;passenger side). Poor night visibility due to sever degradation of oem headlamp system. This makes night driving illegal,dangerous, and just impossible with out some sort of aftermarket lighting system or oem replacements which will soon fail and cause the issue all over again. There is no after market replacement bulb. Ford did not contract with sylvania to make one. I was told that my hid headlight bulb would never burn out. Now I can't even sell my car. If I did find a buyer, it would not be legal to drive with only one working headlight. …”
NHTSA complaint #10218052, filed 2008-02, 71,800 milesSuspension: “The front suspension sinks down on the vehicle, causing the front to scrape on the ground. This is making the ability to drive difficult. Manufacturer was contacted by owner. The consumer stated that the main computer is failing.”
NHTSA complaint #10109284, filed 2005-03, 30,000 milesBrakes: “The contact owns a 1998 Lincoln Mark Viii. While driving at a low speed the contact stated that the rear ABS failed. The dealer could not repair the vehicle because the rear wheel ABS sensor was no longer available. Report 238373 was filed with the manufacturer. The manufacturer attempted to locate the part, but the part was no longer in production; therefore; they could not offer any assistance. The dealer disconnected the rear ABS sensor to ensure that the rear brakes would function properly; yet, it caused the vehicle to vibrate and the ABS light to illuminate constantly. …”
