- Recalls behind the top problems
- 4 recalls are on file, but no problem here has enough reports to set against them.

How this compares
107 complaints is 1.4 times fewer than the median 2023 model on this site and about the median for a 2023 sedan. Among the 4 K5 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
38 complaints came in 2025, 2.0 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.
