Common problems with the 2017 E300
NHTSA's file holds 132 owner complaints on the 2017 Mercedes-Benz E300. Owners named the engine most often: 37 complaints, and half of the 9 that list a mileage came after 18,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 37 | 9 | 19,000 |
| Electrical System | 23 | 7 | 30,000 |
| Fuel/propulsion System | 20 | 4 | Under 5 mileages |
| Power Train | 16 | 11 | 85,000 |
| Steering | 12 | 8 | 59,000 |
Of the 132 complaints, 2 report a crash, 3 report a fire and 5 report an injury (7 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2017 E300
The 55 mileages owners gave run from 20 to 144,000 miles. A quarter are at or under 15,000 miles, half at or under 32,000, three quarters at or under 72,100 and nine in ten at or under 97,000; 4 (7%) 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 2017 E300 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: 51 of the 55 came at or under 100,000 miles, so they say nothing about how many miles a 2017 E300 can cover.
Complaint mileage also follows a model year's age: the 2017 has had less time to cover miles than older years, so its figures will rise as it ages.
| Measure | Value |
|---|---|
| Lowest mileage listed | 20 miles |
| 25th percentile | 15,000 miles |
| Median (50th percentile) | 32,000 miles |
| 75th percentile | 72,100 miles |
| 90th percentile | 97,000 miles |
| Highest mileage listed | 144,000 miles |
| Complaints after 100,000 miles | 4 (7%) |
| Complaints after 150,000 miles | none |
| Complaints after 200,000 miles | none |
Is the 2017 E300 a good year?
Complaint counts cannot say whether the 2017 is a good or a bad E300: they rise with how many were sold and how long they have been on the road. They show how the 2017 compares with the other model years in NHTSA's file.
With 132 complaints, the 2017 drew the most of the 3 Mercedes-Benz E300 model years from 2017 to 2019 with 10 or more complaints. The fewest: the 2019 (30).
NHTSA files the Mercedes-Benz E300 name for 1995–2002 and 2016–2019. A gap of three or more model years means the name covers different vehicles, so the 2017 is compared only with the 2016–2019 model years.
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.

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 2017 E300 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 2017 E300.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 77 of the 132 complaints on the 2017 Mercedes-Benz E300 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: E300 and E 300. 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: E 300 and E300.
