Common problems with the 2004 BMW 5 Series
NHTSA's file holds 64 owner complaints on the 2004 BMW 5 Series. Owners named the airbags most often: 29 complaints, and half of the 27 that list a mileage came after 80,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Air Bags | 29 | 27 | 81,000 |
| Seats | 11 | 9 | 85,000 |
| Electrical System | 9 | 9 | 88,000 |
| Seat Belts | 7 | 7 | 95,000 |

Of the 64 complaints, 1 reports a crash, 9 report a fire and 4 report an injury (4 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2004 BMW 5 Series
The 54 mileages owners gave run from 6,000 to 175,000 miles. A quarter are at or under 60,000 miles, half at or under 78,250, three quarters at or under 92,000 and nine in ten at or under 110,000; 9 (17%) came after 100,000 miles, 2 (4%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2004 BMW 5 Series 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: 45 of the 54 came at or under 100,000 miles, so they say nothing about how many miles a 2004 BMW 5 Series can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 6,000 miles |
| 25th percentile | 60,000 miles |
| Median (50th percentile) | 78,250 miles |

Is the 2004 BMW 5 Series a good year?
Complaint counts cannot say whether the 2004 is a good or a bad BMW 5 Series: 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 64 complaints, the 2004 ranks 4th of the 8 BMW 5 Series model years from 2003 to 2012 with 10 or more complaints, counting from the most. The most: the 2008 (105). The fewest: the 2012 (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 |
|---|---|---|---|
| 2003 BMW 5 Series | 15 | 12 | 90,000 |
| 2004 (this page) | 64 | 54 | 78,250 |
| 2005 BMW 5 Series | 21 | 16 | 70,000 |
| 2006 BMW 5 Series | 85 | 79 | 65,000 |
| 2007 BMW 5 Series | 13 | 11 | 84,089 |

| 2011 BMW 5 Series | 81 | 73 | 2,000 |
| 2012 BMW 5 Series | 10 | 9 | 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 BMW 5 Series 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 BMW 5 Series.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 10 of the 64 complaints on the 2004 BMW 5 Series give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: 5 SERIES and 5-SERIES. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file name matched: 5 SERIES.
