- Recalls behind the top problems
- Each of infotainment and windshield has a recall on the same system: infotainment, 18V-773; windshield, 18V-935. A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
- When owners filed

How this compares
117 complaints is 2.4 times fewer than the median 2018 model on this site and 1.5 times fewer than the median 2018 sedan. Among the 6 Legacy model years here it ranks 6th 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.
