Certain units of the 2023 through 2024 GMC Canyon pickup motivated by the turbocharged 2.7L I4 L3B gasoline engine are included in a new GM Service Update containing a fix available for a fuel injector flow rate problem.
The Engine Control Module (ECM) of the affected GMC Canyon units is incorrectly programmed, per Service Update N242452130. This could potentially lead to an improper fuel flow rate during certain types of driving.
As a reminder, the turbocharged 2.7L I4 L3B TurboMax engine involved in the Service Update develops 310 horsepower and 430 pound-feet of torque in the 2023 and 2024 GMC Canyon.
The exact number of affected units is currently unclear. GM instructs dealership service to apply the available fix to any vehicles still in stock and to affected GMC Canyon trucks brought in by their owners for other services. The repair is offered free of charge to current owners of the vehicles through March 31st, 2040.
No components need to be replaced to repair the fuel injector flow rate. To calibrate the flow rate correctly, the service personnel must reprogram the Engine Control Module with new settings. The whole process, including verifying the issue and reprogramming the ECM, takes about 30 minutes on average.
In late 2023, GM issued a very similar service update with an ECM fix for a fuel injector flow rate problem for the 2023 GMC Canyon. Service Update N232411311 called for the same fix as this new update.
The 2.7L I4 L3B has been the only engine option in the GMC Canyon since its current generation debuted for the 2023 model year. It rides on the GMT31XX platform shared with the Chevy Colorado. Production takes place at the GM Wentzville plant in Missouri.
