How this compares
194 complaints is about the median for a 2020 model on this site and 1.3 times fewer than the median 2020 SUV. Among the 7 Terrain model years here it ranks 4th for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
Complaints filed by year
63 complaints came in 2025, 2.5 times the year before. Owners file in waves when a problem gets press or an investigation, so a spike measures attention as much as failures.
