When your 2024 Jeep Gladiator displays the P0305 code, the engine control module has detected repeated misfires in cylinder 5. The 2024 Gladiator uses the 3.6L Pentastar V6 producing 285 horsepower. With six cylinders numbered 1-6, P0305 is a legitimate diagnostic code.
2024 Gladiator Powertrain
The 2024 Gladiator continues with the proven 3.6L Pentastar V6 as its sole engine option. This naturally aspirated V6 pairs with either a 6-speed manual or 8-speed automatic transmission. All Gladiators have this V6 configuration.
Cylinder 5 Location
On the Pentastar V6, cylinder 5 is positioned on the driver side bank toward the rear. Accessing this cylinder requires removing engine covers and potentially air intake components.
Common Causes
On a newer 2024 model, manufacturing defects or loose connections are more likely than wear-related issues. Ignition coil failure can still occur. Check for TSBs addressing known issues. Spark plug problems are less likely unless there's a defect.
Diagnostic Process
Read all codes and freeze frame data. Check for TSBs. Verify ignition system connections. Inspect cylinder 5's spark plug and ignition coil. A 2024 model should be under warranty.
