How many miles will a GMC Terrain last?
Half of the 1,722 NHTSA owner complaints on the GMC Terrain that list mileage came after 69,000 miles, and 1 in 10 after 125,000 miles.

How many miles is too much for a used Terrain?
There is no hard cutoff. NHTSA's file records when owners reported problems, not when a Terrain wears out, and how a car was maintained matters more than any one odometer figure.
Where the complaints cluster: the middle half came between 39,000 and 100,000 miles, and 4% came after 150,000 miles (63 of 1,722).
Complaint mileage rises with a model year's age: older Terrain years were reported at higher odometer readings because they had more time to cover miles. The table below shows when owners of each year reported problems; it does not rank the years.

GMC Terrain mileage at failure by model year
Each row is a Terrain model year with 10 or more NHTSA complaints that list a mileage, with the median of those mileages: half of the year’s complaints came at or above it. Years with fewer are left out. Medians rise with a year’s age, so the table does not rank the years. A linked year opens that model year’s own page: its problems by component and its recall campaigns.

|---|---|---|
| 2010 Terrain | 234 | 73,850 |
| 2011 Terrain | 296 | 78,000 |
| 2012 Terrain | 258 | 81,107 |
| 2013 Terrain | 241 | 77,550 |
| 2014 Terrain | 194 | 79,000 |

What these mileages can and cannot tell you
- They are self-reported. The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- They are not a lifespan study. The file holds only cars whose owners reported a problem; a Terrain that ran without one never appears in it, so these figures do not say how long a typical Terrain lasts.
- Young model years pull the figures down: a car a few years old cannot have reached high mileage when its owner complained.
- A complaint is an allegation, not a defect finding, and the count rises with how many cars were sold.
- 1,420 of the GMC Terrain complaints in these model years give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every figure.
- NHTSA names counted: TERRAIN.

How do I check the mileage of a used Terrain?
Compare the odometer with the readings on file for its VIN: title transfers, inspections and auction sales record the mileage on the day. A reading lower than an earlier one, or a long gap, is worth asking about.
