Overview

2021 GMC Canyon

The 2021 GMC Canyon offers a capable, if somewhat unrefined, mid-size truck experience. While it boasts solid NHTSA safety scores, particularly in side impacts, potential buyers should be aware of its 'Below Average' LLM reliability assessment. Key concerns include reported airbag non-deployments and powertrain issues. Its 3.6L V6 engine paired with an 8-speed automatic and 4-wheel drive provides adequate motivation for daily driving and moderate hauling. Fuel economy is respectable for its class, though high fuel costs are a consideration. The Canyon's primary appeal lies in its utility, but thorough inspection is paramount for used shoppers.

Critical Failure Risk

Complaints indicate potential airbag non-deployment during collisions. This is a critical safety concern that requires immediate attention if suspected.
