How many miles will a 2012 C300 last?
The 74 mileages owners gave run from 384 to 180,000 miles. A quarter are at or under 50,000 miles, half at or under 82,000, three quarters at or under 115,000 and nine in ten at or under 138,000; 24 (32%) came after 100,000 miles, 3 (4%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2012 C300 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.

Is the 2012 C300 a good year?
Complaint counts cannot say whether the 2012 is a good or a bad C300: they rise with how many were sold and how long they have been on the road. They show how the 2012 compares with the other model years in NHTSA's file.
With 267 complaints, the 2012 ranks 7th of the 17 Mercedes-Benz C300 model years from 2008 to 2024 with 10 or more complaints, counting from the most. The most: the 2008 (672). The fewest: the 2024 (14).
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.

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 2012 C300 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 2012 C300.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 193 of the 267 complaints on the 2012 Mercedes-Benz C300 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: C300, C 300 and C 300 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: C 300, C 300 4MATIC and C300.
