The 2010 (241) and 2012 (171) drew the most owner complaints to NHTSA of the 2010–2015 Mercedes-Benz GLK-Class model years on record, as of November 10, 2026.
NHTSA also holds fewer than 10 complaints and no recall for 2006 and 2007; those stray filings are left out of the table.
Fewest complaints: of the Mercedes-Benz GLK-Class model years from 2010 to 2015 with at least 40 complaints on file, the 2014 (126) and 2015 (133) 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 224 NHTSA owner complaints on the Mercedes-Benz GLK350 that list mileage came after 53,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Mercedes-Benz GLK350 last? →
Mercedes-Benz GLK-Class complaints and recalls by model year, 2010–2015
This table lists the 6 Mercedes-Benz GLK-Class model years NHTSA holds records for between 2010 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 0 distinct recall campaigns.

Mercedes-Benz GLK-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 GLK-Class only. It says nothing about how the GLK-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 GLK-Class year-by-year questions
Which Mercedes-Benz GLK-Class years should I avoid?
Mercedes-Benz GLK-Class years to avoid, by NHTSA owner complaints: the 2010 (241 complaints, led by the airbags at 149 and the fuel system at 26) and the 2012 (171, led by the airbags at 136 and the fuel system at 12) drew the most of the 2010–2015 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. NHTSA also holds fewer than 10 complaints and no recall for 2006 and 2007; those stray filings are left out of the table.
What are the best Mercedes-Benz GLK-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 GLK-Class model years from 2010 to 2015 with at least 40 complaints on file, the 2014 (126) and 2015 (133) 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 GLK-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 GLK-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.
