Common problems with the 2016 FIAT 500X
NHTSA's file holds 154 owner complaints on the 2016 FIAT 500X. Owners named the engine most often: 52 complaints, and half of the 36 that list a mileage came after 31,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 52 | 36 | 32,000 |
| Power Train | 50 | 36 | 38,000 |
| Electrical System | 48 | 32 | 39,900 |
| Exterior Lighting | 14 | 10 | 40,000 |
| Electronic Stability Control (ESC) | 10 | 6 | 30,000 |
Of the 154 complaints, 3 report a crash, 3 report a fire and 2 report an injury (4 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2016 FIAT 500X
The 101 mileages owners gave run from 100 to 301,105 miles. A quarter are at or under 26,500 miles, half at or under 40,000, three quarters at or under 65,000 and nine in ten at or under 86,000; 5 (5%) came after 100,000 miles, 1 (1%) after 150,000 and 1 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 2016 FIAT 500X 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: 96 of the 101 came at or under 100,000 miles, so they say nothing about how many miles a 2016 FIAT 500X can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 100 miles |
| 25th percentile | 26,500 miles |
| Median (50th percentile) | 40,000 miles |
| 75th percentile | 65,000 miles |
| 90th percentile | 86,000 miles |
| Highest mileage listed | 301,105 miles |
| Complaints after 100,000 miles | 5 (5%) |
| Complaints after 150,000 miles | 1 (1%) |
| Complaints after 200,000 miles | 1 (1%) |

Is the 2016 FIAT 500X a good year?
Complaint counts cannot say whether the 2016 is a good or a bad FIAT 500X: they rise with how many were sold and how long they have been on the road. They show how the 2016 compares with the other model years in NHTSA's file.
With 154 complaints, the 2016 drew the most of the 3 FIAT 500X model years from 2016 to 2018 with 10 or more complaints. The fewest: the 2018 (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 |
|---|---|---|---|
| 2016 (this page) | 154 | 101 | 40,000 |
| 2017 FIAT 500X | 17 | 7 | Under 10 mileages |
| 2018 FIAT 500X | 11 | 3 | 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 2016 FIAT 500X 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 2016 FIAT 500X.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 53 of the 154 complaints on the 2016 FIAT 500X 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: 500X. 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: 500X.
