Questions

FAQ

Is the 2014 GMC Terrain reliable?
Owners have filed 302 safety complaints with NHTSA for the 2014 GMC Terrain, most often about engine. Compare the complaint counts across model years above — a year with far more complaints than the model's average is the strongest 'avoid' signal in public data.
Which GMC Terrain years should I avoid?
The rule of thumb used by analysts: a model year whose complaint count is well above the model's own average (we flag 2× or more) usually had a real manufacturing or design problem — not just noisy reporting. Use the year-by-year strip on this page.
Where do these complaints come from?
Directly from NHTSA, the US government road-safety agency. Any owner can file a Vehicle Owner Questionnaire; NHTSA publishes them as public domain data. We cache each lookup for up to 7 days.
Do complaints mean a recall is coming?
Sometimes. NHTSA opens defect investigations when complaint patterns emerge, and investigations can end in recalls. Check the recalls page for this vehicle to see what has already been recalled.
