Mercedes BENZ E Class
The Mercedes-Benz E-Class, based on NHTSA data, shows a high volume of complaints, averaging 40 per year over a decade.

Buyer analysis
Mercedes BENZ E Class or Mercedes BENZ A Class: which should you buy?
The Mercedes-Benz A-Class has fewer complaints per year (19.3) compared to the E-Class (40.0), but both exhibit serious safety-related failures. The E-Class has a longer history and more reported incidents, but the A-Class's issues are equally concerning. In practice, the A-Class may be slightly less problematic, but both require careful inspection and maintenance.
Key differences
- The E-Class has a higher complaint volume (400 vs 77) and more years of data, but the A-Class has a higher rate of electrical system complaints relative to its total.
- Both have engine shutdown issues, but the E-Class specifically mentions stop/start system malfunctions, while the A-Class reports more transmission-related stalling.
- The E-Class has more reported crashes (14 vs 3) and injuries (27 vs 3), possibly due to higher usage or more severe failures.
- Neither has recalls, but the A-Class is newer, so its long-term reliability is less proven.
- Inspect the stop/start system and battery condition, as engine shutdowns are a common complaint.
- Check for any transmission shifting issues, especially when changing from drive to reverse or vice versa.
- Test drive at various speeds to see if the car shuts down or enters limp mode, as this is a reported issue.
- Check the electrical system, including the battery and alternator, for signs of failure that could cause sudden power loss.
Before you buy
- Obtain a vehicle history report and check for any open recalls or service campaigns.
- Have a trusted mechanic perform a pre-purchase inspection, focusing on engine, transmission, and electrical systems.
- Test drive the car in stop-and-go traffic and on the highway to see if any stalling or shutdown occurs.
- Ask for maintenance records, especially for any previous repairs related to the engine or electrical system.
- Consider purchasing an extended warranty to cover potential costly repairs.
