The P0302 diagnostic code on your 2024 Jeep Grand Cherokee indicates cylinder 2 is experiencing misfires detected by the engine control module. The fifth-generation Grand Cherokee offers multiple powertrains: the 3.6L Pentastar V6, 5.7L Hemi V8, and 4xe plug-in hybrid. Each configuration has specific diagnostic considerations.
Powertrain Lineup
The 3.6L V6 produces 293 horsepower with eTorque mild hybrid. The 5.7L Hemi delivers 357 horsepower with Multi-Displacement System (MDS). The 4xe combines a 2.0L turbo with electric motors for 375 combined horsepower. Cylinder 2 location varies by engine configuration.
V6 Considerations
On the 60-degree V6, cylinder 2 is on the rear bank. Port injection avoids carbon concerns. Common causes include ignition coil failure, spark plug wear, and fuel injector issues. The eTorque system adds mild hybrid complexity.
V8 MDS Specifics
The 5.7L Hemi's cylinder 2 is part of the MDS deactivation system. MDS lifter issues can cause cylinder-specific misfires. Ignition components and fuel system problems are also common causes.
4xe Hybrid
The plug-in hybrid's 2.0L turbo places cylinder 2 second from front. Direct injection and electric motor coordination add complexity. Boost and hybrid system codes may accompany misfire diagnosis.
