What is your E350 doing?
Each one opens a sheet built from the owner reports of that problem on the 2014 model year.
Is the 2014 Mercedes-Benz E350 reliable?
The 2014 Mercedes-Benz E350 has 266 owner complaints on file with NHTSA, close to the median of 318 for 2014 sedans on this site. Of the 3 E350 model years since 2014, it has the most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.
At a glance
- Next to other model years
- Complaints filed before 2015 aren't in the files this site reads, so the 2014 count runs short and isn't compared with the model years next to it.
- Top problem
- Two problems run close. Airbag has 49 complaints and brake wear has 47, out of 266 in all. Too few of the airbag reports give a mileage to say when it starts.
- Crash, fire and injury reports
- 25 of the 266 complaints (9%) report a crash, a fire or an injury. The typical vehicle on this site sits at 6%, so this one runs well above it. Counted separately (one report can carry more than one), 10 reports mention a crash, 14 mention a fire and 9 people were hurt. The most crash reports, 4 of 10, fall under airbag.
- Recalls behind the top problems
- Airbag has a recall on the same system (17V-627, 19V-010 and 21V-638). Brake wear and suspension have none. A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
- When owners filed
- Filings peaked in 2022 at 41 (full calendar years only). In 2025 there were 26. So far in 2026, 13 more have come in. Filings on record start in 2015.

How this compares
266 complaints is about the median for a 2014 model on this site and 1.2 times fewer than the median 2014 sedan. Among the 1 E350 model years here it ranks 1st for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
