How this compares
392 complaints is 1.4 times the median 2018 model on this site and 1.2 times the median 2018 SUV. Among the 7 Acadia model years here it ranks 3rd 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
84 complaints came in 2019, 9.3 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.
