1998 Ford Expedition at 110,000 miles
You did not give a mileage, so this uses 110,000 — the median reported failure mileage for this model year, which is a rough stand-in for “a typical example of this car”. Put your real reading in the box below for an answer about your car.
At 110,000 miles on this car
At 110,000 miles on a 1998 Ford Expedition, 30 of the failure modes other owners have reported already have their median report at or below your reading, and 7 more fall inside the window where they are usually reported. The heaviest of the ones already due is other suspension problem.
Already past the median 30
Half of all reports of these failures came in at or below where your car is now.
- Other suspension problem 86k
- Other electrical problem 98k
- Other wheel or tire problem 81k
- Other visibility problem 70k

Why the list is generic until you type a number
Every figure below is a comparison against your odometer, so with no reading given the page has to pick one: 110,000 miles, roughly what a 1998 car covers at 12,000 miles a year. A reading 30,000 miles either side of that moves failures between the columns, which is the difference between a useful list and a generic one.
Already inside the reported range
30 failure modes on the 1998 Ford Expedition have a median reported mileage at or below 110,000: other suspension problem (median 85,000 miles, 110 reports), other electrical problem (median 97,500 miles, 63 reports), other wheel or tire problem (median 80,000 miles, 53 reports), other visibility problem (median 70,000 miles, 32 reports), ABS module or sensor failure (median 55,000 miles, 30 reports) and steering rack, gear or tie rod failure (median 65,000 miles, 22 reports).
Half the owners who reported each of these had done so by that mileage, which means half had not. A failure being "due" here is a statement about other people's cars, and the useful response is an inspection rather than a pre-emptive repair.
The window you are in now
7 further modes are reported in a band that includes 110,000 miles: misfire or rough idle (84k to 145,000 miles), no-start or intermittent start failure (100k to 120,000 miles), other engine problem (90k to 140,000 miles), cruise control failure (103k to 170,000 miles), other powertrain problem (104k to 160,000 miles) and other speed control problem (102k to 160,000 miles). These are the ones to watch on this car over the next few thousand miles.
A window here is the 25th to 75th percentile of reported mileages, so it holds the middle half of the reports and excludes the tails on both sides.
Still ahead of you
16 further modes sit above your reading, the nearest being loss of braking at a median of 120,000 miles. On a car you intend to keep, these are the ones that decide whether it is worth keeping.
What this list is not
It is a reading of what owners of other 1998 Ford Expeditions reported, and at what odometer reading they reported it. It is not a maintenance schedule, not a diagnosis, and not a prediction about this car: two identical cars with different service histories are not the same car.
Complaints are filed voluntarily, mileages are typed in by owners and cluster on round numbers, and a failure mode with few reports has a wide window even when the median looks precise. Modes with fewer than 8 dated reports are shown without percentiles for that reason.
Where 110,000 miles falls on the curve
The three columns above sort the failure modes one by one. This is the same evidence in aggregate: every dated report on this model year, stacked up in the order the odometer readings arrived. The dashed line marked you is where your car sits. How much of the line is to the left of that mark is how much of this model year's reported trouble is, on the evidence, already behind you.
About 49% of the dated reports on this model year had already been filed by 110,000 miles. That is the share of the problems that show up in this record, not of the problems this car will have. A further 29 reports came in above the top of the scale, which is why the line stops short of the top.
- Line share of reports filed by that mileage
- Dashed the mileages called out above
A steep early climb means a car whose reports cluster young, which is the pattern of a defect rather than of wear. A line that only gets going past six figures is the opposite. Neither shape says anything about the specific car in your driveway, and a curve built from a few dozen readings can be moved by one owner with a talkative afternoon.

Questions this page answers
What should I expect at 110,000 miles on a 1998 Ford Expedition?
30 of the failure modes owners have reported on the 1998 Ford Expedition have a median report at or below 110,000 miles, and 7 more fall inside the mileage window where they are usually reported. That is a watch list drawn from other owners, not a prediction about this car.
How to use the three columns. The left column is the list to hand a mechanic before you buy, and to check the service history for if you already own the car. The middle column is what to budget for this year. The right column is not a reprieve — it is a reminder that a used car has a bill schedule, and this is roughly where it falls. All of it is drawn from 1,022 owner complaints about this exact model year, not from a maintenance manual. How the percentiles are computed.
