2019 GMC Terrain
This year drew an ordinary 178 complaints for a GMC Terrain — the model's median is 151. What they were about is the unusual part: 6.2% of them mention let, against 1.7% across the other years of this generation.
Generation 2 of the GMC Terrain, which began in 2018. 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
- let — 6.2% of this year's complaints, against 1.7% across the other years of this generation (3.6×). Owners wrote it as: let, told vacuum.
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
When trying to accelerate, the car will not accelerate. It will start to jerk back and forth and I had cut it off completely in the middle of the road at a stop light.
Vacuum pump exploded into camshaft and engine area, causing me to lose brakes completely on the highway. Costly repairs to clear out metal shrapnel and replace camshaft.
Verbatim from NHTSA complaint filings, with identifying details removed.

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.
