How many miles will a 2005 Montego last?
The 122 mileages owners gave run from 5 to 270,000 miles. A quarter are at or under 50,000 miles, half at or under 69,179, three quarters at or under 108,000 and nine in ten at or under 147,000; 34 (28%) came after 100,000 miles, 8 (7%) after 150,000 and 2 (2%) after 200,000.
These mileages say when owners reported a problem, not when a 2005 Montego wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Is the 2005 Montego a good year?
Complaint counts cannot say whether the 2005 is a good or a bad Montego: they rise with how many were sold and how long they have been on the road. They show how the 2005 compares with the other model years in NHTSA's file.
With 135 complaints, the 2005 drew the most of the 3 Mercury Montego model years from 2005 to 2007 with 10 or more complaints. The fewest: the 2007 (36).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2005 (this page) | 135 | 122 | 69,179 |
| 2006 Montego | 85 | 69 | 66,000 |
| 2007 Montego | 36 | 34 | 66,500 |
2005 Mercury Montego recalls

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2005 Montego lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2005 Montego.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 13 of the 135 complaints on the 2005 Mercury Montego give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: MONTEGO. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: MONTEGO.
