Problems:
Dynamic brake support (dbs) malfunction
Issues with dynamic brake support not activating or responding correctly, possibly due to sensor malfunctions or software issues.
Variable valve timing (vvt) issues
Problems with the VVT system can cause rough idling, poor acceleration, and increased emissions due to oil control valve failures or timing chain wear.
Direct injection carbon build-up
Direct injection engines can experience carbon build-up on intake valves, leading to reduced performance, rough idling, and poor fuel economy.
Engine misfire
Misfires in the V-shaped 6-cylinder engine can be caused by ignition coil failures, faulty spark plugs, or fuel injector issues.
Cooling system problems
Overheating can occur due to coolant leaks, water pump failures, or radiator issues, which are common in the 2018 GMC Canyon.
Transmission shifting issues
The automatic transmission may experience hard shifts, delayed engagement, or slipping, often due to transmission control module (TCM) or valve body issues.
Fuel pump failure
Fuel pump problems can lead to stalling, difficulty starting, or loss of power, especially under heavy load or acceleration.
Oil consumption
Excessive oil consumption can be an issue with the LGZ engine, often due to piston ring wear or valve seal problems.
Timing chain wear
Premature wear of the timing chain can cause rattling noises, poor engine performance, and potential engine damage if not addressed.
Electronic throttle control (etc) problems
Issues with the ETC can cause erratic idling, poor throttle response, and engine stalling.
Exhaust system leaks
Exhaust leaks can occur at the manifold or gaskets, leading to increased noise, emissions issues, and potential damage to other components like the catalytic converter.
