2006 Mercury Mountaineer at 58,945 miles
You did not give a mileage, so this uses 58,945 — 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 58,945 miles on this car
At 58,945 miles on a 2006 Mercury Mountaineer, 11 of the failure modes other owners have reported already have their median report at or below your reading, and 0 more fall inside the window where they are usually reported. The heaviest of the ones already due is radiator or coolant leak.
Already past the median 11
Half of all reports of these failures came in at or below where your car is now.
- Radiator or coolant leak 59k
- Other powertrain problem 51k
- Other engine problem 56k
- Other wheel or tire problem 8k
- Parking brake failure 6k
- Catalytic converter failure 411
- Other electrical problem 14k
- Other speed control problem 28k
- Control module (ECM/PCM/BCM) failure 11k
- Other brake problem 54k
- Other visibility problem 33k

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: 58,945 miles, roughly what a 2006 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
11 failure modes on the 2006 Mercury Mountaineer have a median reported mileage at or below 58,945: radiator or coolant leak (median 60,000 miles, 51 reports), other powertrain problem (median 50,000 miles, 30 reports), other engine problem (median 55,000 miles, 8 reports), other wheel or tire problem (median 10,000 miles, 4 reports), parking brake failure (median 5,000 miles, 3 reports) and catalytic converter failure (median 400 miles, 3 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.
Still ahead of you
15 further modes sit above your reading, the nearest being fuel tank, filler or EVAP failure at a median of 60,000 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 2006 Mercury Mountaineers 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 58,945 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 32% of the dated reports on this model year had already been filed by 58,945 miles. That is the share of the problems that show up in this record, not of the problems this car will have.
- 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 58,945 miles on a 2006 Mercury Mountaineer?
11 of the failure modes owners have reported on the 2006 Mercury Mountaineer have a median report at or below 58,945 miles, and 0 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 153 owner complaints about this exact model year, not from a maintenance manual. How the percentiles are computed.
