How many miles will a 2004 RX-8 last?
The 399 mileages owners gave run from 10 to 477,775 miles. A quarter are at or under 44,000 miles, half at or under 67,900, three quarters at or under 90,000 and nine in ten at or under 110,000; 66 (17%) came after 100,000 miles, 5 (1%) after 150,000 and 2 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 2004 RX-8 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: 333 of the 399 came at or under 100,000 miles. The 66 past that mark show the 2004 RX-8 still being driven at those mileages, not how many reach them: NHTSA's file counts complaints, not the vehicles on the road.

Common problems with the 2004 RX-8
NHTSA's file holds 490 owner complaints on the 2004 Mazda RX-8. Owners named the powertrain most often: 154 complaints, and half of the 143 that list a mileage came after 69,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Power Train | 154 | 143 | 69,600 |
| Engine And Engine Cooling | 106 | 83 | 45,000 |
| Steering | 80 | 72 | 85,000 |

| Electrical System | 33 | 27 | 40,600 |
Of the 490 complaints, 17 report a crash, 10 report a fire and 15 report an injury (15 people reported injured). These are owners' reports to NHTSA, not findings.
Is the 2004 RX-8 a good year?
Complaint counts cannot say whether the 2004 is a good or a bad RX-8: 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 490 complaints, the 2004 drew the most of the 5 Mazda RX-8 model years from 2004 to 2008 with 10 or more complaints. The fewest: the 2008 (17).
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 |
|---|---|---|---|
| 2004 (this page) | 490 | 399 | 67,900 |
| 2005 RX-8 | 162 | 125 | 62,000 |
| 2006 RX-8 | 60 | 48 | 55,500 |
| 2007 RX-8 | 38 | 29 | 72,000 |
| 2008 RX-8 | 17 | 12 | 62,000 |

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 RX-8 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 RX-8.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 91 of the 490 complaints on the 2004 Mazda RX-8 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: RX-8. 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: RX-8.
