Common problems with the 2020 Gladiator
NHTSA's file holds 485 owner complaints on the 2020 Jeep Gladiator. Owners named the electrical system most often: 183 complaints, and half of the 45 that list a mileage came after 53,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Electrical System | 183 | 45 | 54,000 |
| Steering | 182 | 115 | 500 |
| Power Train | 55 | 20 | 11,000 |
| Engine | 45 | 13 | 1,036 |
| Suspension | 32 | 16 | 5,000 |
Of the 485 complaints, 11 report a crash, 7 report a fire and 5 report an injury (6 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2020 Gladiator
The 212 mileages owners gave run from 1 to 300,000 miles. A quarter are at or under 250 miles, half at or under 3,000, three quarters at or under 24,000 and nine in ten at or under 60,000; 4 (2%) came after 100,000 miles, 1 (under 1%) after 150,000 and 1 (under 1%) after 200,000.
These mileages say when owners reported a problem, not when a 2020 Gladiator 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: 208 of the 212 came at or under 100,000 miles, so they say nothing about how many miles a 2020 Gladiator can cover.
Complaint mileage also follows a model year's age: the 2020 has had less time to cover miles than older years, so its figures will rise as it ages.
| Measure | Value |
|---|---|
| Lowest mileage listed | 1 mile |
| 25th percentile | 250 miles |
| Median (50th percentile) | 3,000 miles |
| 75th percentile | 24,000 miles |
| 90th percentile | 60,000 miles |
| Highest mileage listed | 300,000 miles |
| Complaints after 100,000 miles | 4 (2%) |
| Complaints after 150,000 miles | 1 (under 1%) |
| Complaints after 200,000 miles | 1 (under 1%) |

Is the 2020 Gladiator a good year?
Complaint counts cannot say whether the 2020 is a good or a bad Gladiator: they rise with how many were sold and how long they have been on the road. They show how the 2020 compares with the other model years in NHTSA's file.
With 485 complaints, the 2020 drew the most of the 6 Jeep Gladiator model years from 2020 to 2025 with 10 or more complaints. The fewest: the 2025 (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 |
|---|---|---|---|
| 2020 (this page) | 485 | 212 | 3,000 |
| 2021 Gladiator | 294 | 47 | 20,000 |
| 2022 Gladiator | 121 | 21 | 20,000 |
| 2023 Gladiator | 57 | 7 | Under 10 mileages |
| 2024 Gladiator | 23 | 2 | Under 10 mileages |
| 2025 Gladiator | 17 | 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 2020 Gladiator 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 2020 Gladiator.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 273 of the 485 complaints on the 2020 Jeep Gladiator 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: GLADIATOR. 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: GLADIATOR.
