Overview

2018 GMC Canyon

The 2018 GMC Canyon offers a rugged, mid-size truck platform, but used buyers should proceed with caution. While it boasts a 4-star overall safety rating, its reliability record is marred by frequent powertrain complaints. The 3.6L V6 engine paired with an 8-speed automatic transmission delivers adequate power for its class, but the transmission's tendency for shuddering and rough shifts is a significant concern. With 63 complaints logged, including issues with the electrical system and engine, potential buyers must prioritize a thorough inspection.

Critical Failure Risk

Frequent complaints center on transmission shuddering, rough shifting, and clunking noises, particularly between gears or during acceleration. This can feel like a significant jolt, impacting driving comfort and potentially safety.

Early detection can help you avoid a $1,500-$3,500 repair.
