2015 GMC Terrain
This year drew an ordinary 315 complaints for a GMC Terrain — the model's median is 151. What they were about is the unusual part: 28.3% of them mention wiper, against 10.5% across the other years of this generation.
Generation 1 of the GMC Terrain, which began in 2010 and ran to 2017. Everything below compares this year against the others in that generation, not against a different car wearing the same name.
NHTSA opened a defect investigation into this model year.

What the complaints were about
- wiper — 28.3% of this year's complaints, against 10.5% across the other years of this generation (2.7×). Owners wrote it as: wiper, rain, rain storm, linkage.
Words owners used for the same problem are counted together, so a fault written four different ways is measured once. Grouped by which complaints they appear in, not by a list anyone wrote in advance.
What owners wrote
THIS MORNING ON MY WAY TO WORK ON 95 NORTH BOUND AND MY WIPER BLADES STOPPED WORKING. I WAS DOING ABOUT 65-70 MPH AND IT WAS POURING RAIN OUT AND I COULD BARELY SEE IN FRONT OF ME. IT WAS DEFINITELY DANGEROUS FOR ME TO KEEP DRIVING BUT I HAD TO GET TO WORK SO…

How this was worked out
Every year of the GMC Terrain was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
