GM has issued a service update, bulletin number N232409000, for certain units of the 2023 Chevy Colorado and 2023 GMC Canyon that may have a condition in which the engine wiring harness chafes against the turbo actuator.
Some 2023 Chevy Colorado and 2023 GMC Canyon units were built without sufficient clearance between the engine wiring harness and the turbo actuator. The insufficient clearance may cause chafing between the harness and actuator on Chevy Colorado and GMC Canyon units with the problematic assembly, but GM has not specified any hazards associated with the condition.
In order to fix this issue, certified GM technicians at dealerships are instructed to install two Nylon Cable Ties on the engine wiring harness to prevent further chafing.
GM further states that involvement of a specific 2023 Chevy Colorado or 2023 GMC Canyon truck should be confirmed before beginning inspection or repairs, both on current dealer stock and on vehicles brought to the dealership by owners for servicing. Affected trucks are marked as “Open” on the Investigate Vehicle History screen of the GM Global Warranty Management system.
GM has determined a total of nine (9) trucks, including both 2023 Chevy Colorado and 2023 GMC Canyon units, are affected by the issue. Because of the small number of units involved, GM advises dealerships to avoid ordering parts until involvement of a specific unit in the service bulletin issue is confirmed.
The fix is available for affected Chevy Colorado and GMC Canyon units until the end of the affected truck’s New Vehicle Limited Warranty period.

The 2023 model year of the Chevy Colorado and GMC Canyon debuted the all-new third generation for both truck models, with both receiving a complete overhaul.
