Common problems with the 2021 GLE 350
NHTSA's file holds 57 owner complaints on the 2021 Mercedes-Benz GLE 350. Owners named the engine most often: 28 complaints. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 28 | 4 | Under 5 mileages |
| Electrical System | 13 | 4 | Under 5 mileages |
| Power Train | 5 | 0 | Under 5 mileages |
| Visibility | 5 | 4 | Under 5 mileages |
| Forward Collision Avoidance | 4 | 0 | Under 5 mileages |
Of the 57 complaints, 3 report a crash, 3 report a fire and 2 report an injury (6 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2021 GLE 350
The 14 mileages owners gave run from 500 to 100,000 miles, and half are at or under 49,045. With fewer than 20 mileages this page gives the median only: the other percentiles are too few to say. None came after 100,000 miles, none after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2021 GLE 350 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: all 14 came at or under 100,000 miles, so they say nothing about how many miles a 2021 GLE 350 can cover.
Complaint mileage also follows a model year's age: the 2021 has had less time to cover miles than older years, so its figures will rise as it ages.
| Measure | Value |
|---|---|
| Lowest mileage listed | 500 miles |
| 25th percentile | Too few to say |
| Median (50th percentile) | 49,045 miles |
| 75th percentile | Too few to say |
| 90th percentile | Too few to say |
| Highest mileage listed | 100,000 miles |
| Complaints after 100,000 miles | none |
| Complaints after 150,000 miles | none |
| Complaints after 200,000 miles | none |
Is the 2021 GLE 350 a good year?
Complaint counts cannot say whether the 2021 is a good or a bad GLE 350: they rise with how many were sold and how long they have been on the road. They show how the 2021 compares with the other model years in NHTSA's file.
With 57 complaints, the 2021 ranks 3rd of the 9 Mercedes-Benz GLE 350 model years from 2016 to 2025 with 10 or more complaints, counting from the most. The most: the 2020 (91). The fewest: the 2025 (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 GLE 350 | 53 | 25 | 59,831 |
| 2017 GLE 350 | 62 | 25 | 20,177 |
| 2018 GLE 350 | 41 | 23 | 20,004 |
| 2020 GLE 350 | 91 | 23 | 22,000 |
| 2021 (this page) | 57 | 14 | 49,045 |
| 2022 GLE 350 | 41 | 11 | 10,000 |
| 2023 GLE 350 | 16 | 2 | Under 10 mileages |
| 2024 GLE 350 | 21 | 2 | Under 10 mileages |
| 2025 GLE 350 | 11 | 1 | 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 2021 GLE 350 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 2021 GLE 350.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 43 of the 57 complaints on the 2021 Mercedes-Benz GLE 350 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: GLE 350, GLE350 and GLE 350 4MATIC. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: GLE 350, GLE 350 4MATIC and GLE350.
