Mileage when owners reported a problem with the 2004 E-Class
The 14 mileages owners gave run from 30 to 160,000 miles, and half are at or under 4,900. With fewer than 20 mileages this page gives the median only: the other percentiles are too few to say. 1 came after 100,000 miles, 1 after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2004 E-Class 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.
Most of these reports came early in the vehicle's life: 13 of the 14 came at or under 100,000 miles, so they say nothing about how many miles a 2004 E-Class can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 30 miles |
| 25th percentile | Too few to say |
| Median (50th percentile) | 4,900 miles |
| 75th percentile | Too few to say |
| 90th percentile | Too few to say |
| Highest mileage listed | 160,000 miles |
| Complaints after 100,000 miles | 1 of 14 |
| Complaints after 150,000 miles | 1 of 14 |
| Complaints after 200,000 miles | none |

Is the 2004 E-Class a good year?
Complaint counts cannot say whether the 2004 is a good or a bad E-Class: 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 15 complaints, the 2004 ranks 8th of the 11 Mercedes-Benz E-Class model years from 1994 to 2006 with 10 or more complaints, counting from the most, tied with 2001. The most: the 2003 (45). The fewest: the 2006 (10).
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 |
|---|---|---|---|
| 1994 E-Class | 38 | 30 | 110,000 |
| 1995 E-Class | 21 | 19 | 170,000 |
| 1996 E-Class | 16 | 10 | 125,000 |
| 1997 E-Class | 38 | 25 | 90,000 |
| 1998 E-Class | 24 | 15 | 98,000 |
| 1999 E-Class | 13 | 9 | Under 10 mileages |
| 2000 E-Class | 34 | 21 | 78,800 |
| 2001 E-Class | 15 | 6 | Under 10 mileages |
| 2003 E-Class | 45 | 34 | 8,945 |
| 2004 (this page) | 15 | 14 | 4,900 |
| 2006 E-Class | 10 | 9 | Under 10 mileages |

2004 Mercedes-Benz E-Class recalls
NHTSA's recall files of November 11, 2026 list 4 recall campaigns that name the 2004 Mercedes-Benz E-Class. A campaign covers a production range, not every vehicle of the model year: check the VIN with NHTSA's free recall lookup.
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 E-Class 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 E-Class.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 1 of the 15 complaints on the 2004 Mercedes-Benz E-Class gives no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and is left out of every mileage figure.
- NHTSA name counted: E CLASS. 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: E CLASS.
