Model years Chevrolet Colorado
2018 Chevrolet Colorado
This year drew an ordinary 180 complaints for a Chevrolet Colorado — the model's median is 81. What they were about is the unusual part: 28.9% of them mention transmission, against 8.2% across the other years of this generation.
Generation 2 of the Chevrolet Colorado, which began in 2015 and ran to 2022. 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.

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

How this was worked out
Every year of the Chevrolet Colorado 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.
