How many miles will a 2004 Century last?
The 34 mileages owners gave run from 1 to 177,000 miles. A quarter are at or under 37,000 miles, half at or under 70,000, three quarters at or under 125,887 and nine in ten at or under 152,000; 13 (38%) came after 100,000 miles, 4 (12%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2004 Century 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 2004 Century a good year?
Complaint counts cannot say whether the 2004 is a good or a bad Century: they rise with how many were sold and how long they have been on the road. They show how the 2004 compares with the other model years in NHTSA's file.
With 39 complaints, the 2004 ranks 14th of the 20 Buick Century model years from 1986 to 2005 with 10 or more complaints, counting from the most. The most: the 1999 (235). The fewest: the 1988 (16).
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 |
|---|---|---|---|
| 1986 Century | 22 | 1 | Under 10 mileages |
| 1987 Century | 28 | 1 | Under 10 mileages |
| 1988 Century | 16 | 0 | Under 10 mileages |
| 1989 Century | 40 | 1 | Under 10 mileages |
| 1990 Century | 32 | 0 | Under 10 mileages |

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 2004 Century 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 2004 Century.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 5 of the 39 complaints on the 2004 Buick Century 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: CENTURY. 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: CENTURY.
