Common problems with the 2014 E350
NHTSA's file holds 278 owner complaints on the 2014 Mercedes-Benz E350. Owners named the airbags most often: 49 complaints, and half of the 5 that list a mileage came after 27,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Air Bags | 49 | 5 | 28,000 |
| Service Brakes | 46 | 7 | 41,000 |
| Electrical System | 38 | 20 | 47,200 |
| Suspension | 30 | 3 | Under 5 mileages |
| Steering | 27 | 13 | 50,000 |
Of the 278 complaints, 10 report a crash, 14 report a fire and 7 report an injury (9 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2014 E350
The 102 mileages owners gave run from 1 to 300,000 miles. A quarter are at or under 14,700 miles, half at or under 46,000, three quarters at or under 75,000 and nine in ten at or under 92,000; 8 (8%) came after 100,000 miles, 2 (2%) after 150,000 and 1 (1%) after 200,000.
These mileages say when owners reported a problem, not when a 2014 E350 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: 94 of the 102 came at or under 100,000 miles, so they say nothing about how many miles a 2014 E350 can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 1 mile |
| 25th percentile | 14,700 miles |
| Median (50th percentile) | 46,000 miles |
| 75th percentile | 75,000 miles |
| 90th percentile | 92,000 miles |
| Highest mileage listed | 300,000 miles |
| Complaints after 100,000 miles | 8 (8%) |
| Complaints after 150,000 miles | 2 (2%) |
| Complaints after 200,000 miles | 1 (1%) |

Is the 2014 E350 a good year?
Complaint counts cannot say whether the 2014 is a good or a bad E350: they rise with how many were sold and how long they have been on the road. They show how the 2014 compares with the other model years in NHTSA's file.
With 278 complaints, the 2014 ranks 3rd of the 14 Mercedes-Benz E350 model years from 2004 to 2021 with 10 or more complaints, counting from the most. The most: the 2006 (400). The fewest: the 2004 (10).
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 |
|---|---|---|---|
| 2004 E350 | 10 | 9 | Under 10 mileages |
| 2005 E350 | 15 | 13 | 85,000 |
| 2006 E350 | 400 | 333 | 90,000 |
| 2007 E350 | 351 | 296 | 76,000 |
| 2008 E350 | 174 | 134 | 86,500 |

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 2014 E350 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 2014 E350.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 176 of the 278 complaints on the 2014 Mercedes-Benz E350 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: E350, E 350 and E 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: E 350 and E350.
