4/5 Overall
NHTSA 5-Star Safety Rating
Powertrain complaints dominate the 2018 GMC Canyon's owner report history, accounting for nearly half of all filed complaints. The most frequently described issue is transmission behavior, owners report shuddering, vibration, and a rumbling or rough sensation that typically starts around 45 mph and up, sometimes described as feeling like driving over a rumble strip. Some owners also report knocking sounds traced to the transmission rather than the engine, and in several cases dealers have recommended full transmission replacement. Four-wheel drive failures appear as a secondary pattern, with owners describing the system becoming inoperable in winter conditions, often accompanied by a "Service 4WD" warning message. Electrical system complaints, while fewer, include reduced engine power warnings tied to the DEF system. A single complaint mentions airbag non-deployment in a rear-end collision, though that report stands alone and does not represent a broader pattern in this complaint set.

With Injuries
By System
The 2018 GMC Canyon has 2 recalls, both involving the high-pressure fuel pump and both carrying the risk of a fuel leak that could lead to an engine fire.
On one side, a weld on the fuel pump joint can crack over time and allow fuel to escape. On the other, the pump itself can detach from its mounting flange and damage the high-pressure fuel line, again creating a leak. Both conditions raise the risk of fire if fuel contacts an ignition source.
