How many miles will a 2012 Terrain last?
The 258 mileages owners gave run from 4 to 253,000 miles. A quarter are at or under 57,000 miles, half at or under 81,107, three quarters at or under 105,649 and nine in ten at or under 126,000; 73 (28%) came after 100,000 miles, 8 (3%) after 150,000 and 1 (under 1%) after 200,000.
These mileages say when owners reported a problem, not when a 2012 Terrain 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.

| Visibility/wiper | 74 | 56 | 88,915 |

Is the 2012 Terrain a good year?
Complaint counts cannot say whether the 2012 is a good or a bad Terrain: 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 364 complaints, the 2012 ranks 3rd of the 17 GMC Terrain model years from 2010 to 2026 with 10 or more complaints, counting from the most. The most: the 2011 (386). The fewest: the 2025 (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.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2010 Terrain | 290 | 234 | 73,850 |
| 2011 Terrain | 386 | 296 | 78,000 |
| 2012 (this page) | 364 | 258 | 81,107 |
| 2013 Terrain | 365 | 241 | 77,550 |
| 2014 Terrain | 297 | 194 | 79,000 |

| 2026 Terrain | 34 | 7 | Under 10 mileages |
The linked 2015–2022 pages show NHTSA's September 15, 2026 collection, so their counts can differ from this table's.

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 Terrain 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 Terrain.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 106 of the 364 complaints on the 2012 GMC Terrain give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: TERRAIN. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: TERRAIN.
