If your 2024 Chevrolet Traverse is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The completely redesigned 2024 Traverse has moved to a four-cylinder powertrain, dropping the previous generation's V6. With only four cylinders numbered 1-4, P0305 referencing cylinder 5 is technically anomalous.
Major Powertrain Change for 2024
The third-generation 2024 Traverse represents a significant departure from previous models. It uses a 2.5-liter turbocharged four-cylinder engine producing 315 horsepower—more power than the previous V6 despite having fewer cylinders. No V6 option is available on the 2024 Traverse.
Why P0305 Is Anomalous
The new 2.5L turbo engine has exactly four cylinders. A P0305 code references a non-existent cylinder 5, making this an erroneous diagnostic code rather than an actual engine misfire.
Possible Causes for Erroneous Code
As a first-year redesigned model, ECM software calibration issues could cause incorrect code storage. Scan tool compatibility problems with the new platform may misread data. Previous diagnostic equipment data from V6 vehicles could appear. Low 12-volt battery voltage affects computer reliability. Software updates may address early production issues.
Diagnostic Recommendations
Use a GM-compatible scan tool to verify stored codes. Check for TSBs or software updates for the 2024 Traverse. If actual misfire symptoms exist, focus on cylinders 1-4 using standard procedures. Test the 12-volt battery condition. Clear the erroneous code and monitor for recurrence.
