Other powertrain problem on the 2006 Mercury Montego
1 crash 1 of the 17 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other powertrain problem gets reported
Owners of the 2006 Mercury Montego report other powertrain problem at a median of 70,000 miles. A quarter of the reports come in before 60,000 miles and a quarter after 105,000 miles, from 13 reports that carried an odometer reading.
A part like this is normally expected to survive 92,000 miles. It is the 2nd most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 120,000 miles at the ninetieth, a spread of 110,188 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
15% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 8,212 miles | 60,000 miles | 72,000 miles | 103,000 miles | 118,400 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 1 a crash is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $400–$4,500 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 3 model years of this car. It shows up earliest on the 2007, at a median of 55,000 miles, and latest on the 2006 at 70,000 miles.
By volume the 2005 carries the most reports, with 30; the 2006 has 17. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Tl*the contact owns a 2006 mercury montego. While driving at 70 MPH up a hill, the vehicle suddenly shifted out of gear, and made a clunking noise. Prior to the failure, the transmission had been flushed. The vehicle was taken to an authorized dealership where the contact was informed that there was a harsh shifting failure within the transmission. The dealer stated that the contact would be responsible for repair costs as the vehicle was no longer under warranty. The vehicle had not been repaired at the time of the complaint. The failure mileage was approximately 70,000. The current mileage was 76,394. Updated 07/28/10. *lj updated 08/30/10*jb
Transmission-engine interface / program on my 2006 mercury montego is 'wacky' -- to use a technical term..... Purchased the vehicle new in july 2006 and immediately experienced the big problem. It now has about 28,000 miles. Dealer thinks I'm wacky for reporting it and supposedly changed the program the second or third time I reported the problem but it still exists. The problem: with all previous cars I've driven, to go faster you push the accelerator pedal down. To speed up a little you press a little; to speed up a lot you press harder. With this car you press a little: nothing happens. You press a little harder: nothing happens. You press a little harder: nothing happens. Suddenly after a few seconds the car downshifts two or three gears and jumps forward -- with tremendous torque steer. Fortunately, the torque steer is to the right, so I have not as yet veered into oncoming traffic. I've been able to anticipate the problem and control the vehicle so far, but I fear that I or another driver may not always be so attentive. Its potentially extremely dangerous to me and others on or near roads..... *tr
1. Normal driving. Car stopped moving. Stranded xmas evening in rain storm. 2. Rt. Frond axle came out of trans-axle towed to dealer. 3. Found defective midship bearing had to cut due to excessive pressure on axle. Per dealer invoice. *tr

How far this goes
Complaints are voluntary, so 17 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does other powertrain problem happen on the 2006 Mercury Montego?
Across 13 owner reports that included an odometer reading, half were filed by 70,000 miles. A quarter were filed before 60,000 miles and a quarter after 105,000 miles. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is other powertrain problem on the 2006 Mercury Montego?
17 reports have been filed with NHTSA, about 0.8 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
