Re: Terrain reliability stats ASAP (please sign up)

I bought my 2010 3.0 Terrain with 32K miles. It was a one owner car. 3 years later I have just passed 127,000 miles and the only major mechanical jobs I had to complete was:
  • Replace Throttle Body, Clean Fuel Lines, Decarbonize..something (sorry I forgot what it's called) = $1,100, this was all done at once. Which caused the "Reduced Engine Power" warning message and driving ability

I maintenance the oil changes with Royal Purple and the higher-end oil filters. I did have a k&n air filter, but I just went back to OEM filters (fram).

Good luck on your choice.

Re: Terrain reliability stats ASAP (please sign up)

We've updated our reliability stats for the Terrain to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

2016 Terrain: 0, low, small sample size
2015 Terrain: 12, low
2014 Terrain: 19, low
2013 Terrain: 20, low
2012 Terrain: 29, low
2011 Terrain: 60, moderate
2010 Terrain: 85, high

We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:

2015 Terrain: 87, < 1
2014 Terrain: 84, < 1
2013 Terrain: 81, < 1
2011 Terrain: 53, 6
2010 Terrain: 56, 14

We'll have further updates in November and next February. The more owners participate, the more comprehensive and precise these will be.

For the repairs behind these stats, reliability information on other models, and to sign up to help improve this information:
