The 2006 (214) and 2002 (134) drew the most owner complaints to NHTSA of the 2002–2015 Mercedes-Benz M-Class model years on record, as of November 10, 2026.
Close behind: the 2009 (128).
2005 has fewer than 40 complaints on file, too few to compare.
Fewest complaints: of the Mercedes-Benz M-Class model years from 2002 to 2015 with at least 40 complaints on file, the 2004 (53) and 2013 (64) drew the fewest. Fewer complaints can also mean fewer sold or fewer still on the road, so it is a starting point, not a clean bill of health; years after 2020 are left out because they have had less time to collect complaints.
Half of the 1,344 NHTSA owner complaints on the Mercedes-Benz M-Class that list mileage came after 70,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Mercedes-Benz M-Class last? →
Mercedes-Benz M-Class complaints and recalls by model year, 2002–2015
This table lists the 14 Mercedes-Benz M-Class model years NHTSA holds records for between 2002 and 2015, collected from NHTSA’s complaints and recalls APIs on November 10, 2026. Each owner complaint is counted once, by its NHTSA number, and a complaint can name more than one component; recall campaigns are counted once per model year, by campaign number. Across these years NHTSA lists 4 distinct recall campaigns, the newest filed Apr 26, 2024.

Mercedes-Benz M-Class by model year: mileage, problems and recalls
Each page below covers one model year in NHTSA’s complaints file of November 11, 2026: the mileage when owners reported problems, the most-reported components and the recall campaigns NHTSA’s recall files list. That file is a separate collection from the table above and goes back to the 1981 model year, so its counts can differ and it holds years the table does not.
How to read these numbers
- A higher count is not proof of a worse vehicle. Complaint volume rises with sales volume and with years on the road, so older and best-selling years collect more.
- The comparison is between years of the Mercedes-Benz M-Class only. It says nothing about how the M-Class compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. NHTSA’s VIN lookup checks open recalls within its coverage and excludes completed repairs. A zero result does not prove the vehicle’s complete recall or repair history; ask for dated repair documentation.
- NHTSA files some years under body or cab names (for example ACCESS CAB or CREW CAB). This collection asked for the names NHTSA lists, and a year far below its neighbours also under the common cab and body names. Such a year is marked as possibly filed under another name only when NHTSA’s records show it split across names or holding recalls and no complaint; otherwise its count is read as low.

Mercedes-Benz M-Class year-by-year questions
Which Mercedes-Benz M-Class years should I avoid?
Mercedes-Benz M-Class years to avoid, by NHTSA owner complaints: the 2006 (214 complaints, led by the powertrain at 53 and the engine at 39) and the 2002 (134, led by steering at 32 and the electrical system at 25) drew the most of the 2002–2015 model years on record as of November 10, 2026; complaints are owner reports, not proven defects, and the counts also reflect each year’s age and sales. Close behind: the 2009 (128). 2005 has fewer than 40 complaints on file, too few to compare.
What are the best Mercedes-Benz M-Class years?
Complaint counts do not show which model year is best; the closest they come is which years drew the fewest complaints. Of the Mercedes-Benz M-Class model years from 2002 to 2015 with at least 40 complaints on file, the 2004 (53) and 2013 (64) drew the fewest. Fewer complaints can also mean fewer sold or fewer still on the road, so it is a starting point, not a clean bill of health; years after 2020 are left out because they have had less time to collect complaints.
Do complaint counts mean the M-Class is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model, which is what this page does, not for ranking one model against another.
How do I check a specific M-Class before buying?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. It reports open recalls within its coverage and excludes completed repairs. A zero result is not a complete recall or repair history; ask the seller or manufacturer for dated repair documentation. For the vehicle's own past, the original ClearVIN PDF from VIN Lookup shows title brands, odometer readings, accident and auction records on file for that VIN.
