How many miles will a 2015 Sierra 2500 last?
The 58 mileages owners gave run from 10 to 189,458 miles. A quarter are at or under 7,000 miles, half at or under 37,023, three quarters at or under 102,040 and nine in ten at or under 131,208; 16 (28%) came after 100,000 miles, 2 (3%) after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2015 Sierra 2500 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 2015 Sierra 2500 a good year?
Complaint counts cannot say whether the 2015 is a good or a bad Sierra 2500: they rise with how many were sold and how long they have been on the road. They show how the 2015 compares with the other model years in NHTSA's file.
With 91 complaints, the 2015 ranks 7th of the 30 GMC Sierra 2500 model years from 1997 to 2026 with 10 or more complaints, counting from the most. The most: the 2003 (160). The fewest: the 2010 (10).
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 2015 Sierra 2500 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 2015 Sierra 2500.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 33 of the 91 complaints on the 2015 GMC Sierra 2500 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: SIERRA 2500 and SIERRA 2500 HD. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file name matched: SIERRA 2500.
