Mileage when owners reported a problem with the 1999 MX-5 Miata
The 25 mileages owners gave run from 5,800 to 165,000 miles. A quarter are at or under 30,000 miles, half at or under 41,730, three quarters at or under 69,500 and nine in ten at or under 117,000; 3 (12%) came after 100,000 miles, 2 (8%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 1999 MX-5 Miata 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: 22 of the 25 came at or under 100,000 miles, so they say nothing about how many miles a 1999 MX-5 Miata can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 5,800 miles |
| 25th percentile | 30,000 miles |
| Median (50th percentile) | 41,730 miles |
| 75th percentile | 69,500 miles |
| 90th percentile | 117,000 miles |

Is the 1999 MX-5 Miata a good year?
Complaint counts cannot say whether the 1999 is a good or a bad MX-5 Miata: they rise with how many were sold and how long they have been on the road. They show how the 1999 compares with the other model years in NHTSA's file.
With 74 complaints, the 1999 drew the most of the 12 Mazda MX-5 Miata model years from 1990 to 2003 with 10 or more complaints. The fewest: the 1997 (11).
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 |
|---|---|---|---|
| 1990 MX-5 Miata | 28 | 2 | Under 10 mileages |
| 1991 MX-5 Miata | 21 | 8 | Under 10 mileages |
| 1992 MX-5 Miata | 22 | 6 | Under 10 mileages |
| 1994 MX-5 Miata | 18 | 8 | Under 10 mileages |
| 1995 MX-5 Miata | 30 | 4 | Under 10 mileages |
| 1996 MX-5 Miata | 29 | 12 | 64,000 |
| 1997 MX-5 Miata | 11 | 0 | Under 10 mileages |
| 1999 (this page) | 74 | 25 | 41,730 |

NHTSA's recall files of November 11, 2026 list no campaign for the 1999 model year under the name MX-5 MIATA. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 1999 Mazda MX-5 Miata: 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 1999 MX-5 Miata 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 1999 MX-5 Miata.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 49 of the 74 complaints on the 1999 Mazda MX-5 Miata 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: MX-5 MIATA. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
