The P0302 diagnostic code on your 2024 GMC Canyon indicates that the engine control module has detected cylinder 2 misfires exceeding acceptable thresholds. The redesigned Canyon features new powertrains requiring updated diagnostic approaches.
2024 Canyon Powertrain Revolution
The 2024 GMC Canyon received a complete redesign with new engine options: a 2.7L turbocharged four-cylinder as the base engine and an optional 3.0L turbo diesel. Both represent significant changes from previous model years.
2.7L Turbo Four-Cylinder
The new 2.7L turbocharged engine produces substantial power for the midsize truck segment. With only four cylinders, each one is critical to smooth operation. Cylinder 2 misfires significantly affect power delivery and create noticeable rough running.
3.0L Turbo Diesel Analysis
The available 3.0L turbo diesel provides excellent torque for towing. As a diesel, it doesn't use spark ignition—misfires relate to fuel injection, compression, or glow plug function. The common rail injection system requires specialized diagnostic tools.
Turbocharged Engine Diagnostics
Both available engines are turbocharged, introducing boost-related potential causes. Boost leaks, wastegate issues, or intercooler problems can affect cylinder-specific combustion. Check the entire charge air system for integrity.
New Vehicle Warranty
Your 2024 Canyon should be under comprehensive warranty coverage. Misfire issues on a new truck likely indicate isolated component failures covered under warranty. Document symptoms and contact your dealer.
