A P0302 code on your 2022 Hyundai Palisade indicates the powertrain control module has detected misfires in cylinder 2. The 2022 Palisade continues with the 3.8L Lambda II GDI V6 producing 291 horsepower. This proven V6 with direct injection provides excellent performance but requires understanding of GDI engine characteristics for proper diagnosis.
Consistent Powertrain
The 2022 Palisade maintains the same Lambda II V6 used since introduction. Cylinder 2 is on the rear bank of the 60-degree V6. The direct injection system and dual-overhead cam design provide refined power delivery. Well-documented diagnostic techniques apply to this engine.
Typical Misfire Causes
GDI carbon buildup on intake valves develops over time. Ignition coil degradation from heat exposure is common on V6 engines. Spark plug wear reduces ignition efficiency. Fuel injector issues affect cylinder-specific fuel delivery. These are standard GDI engine concerns rather than defects specific to the Palisade.
Recognizing Symptoms
The smooth V6 character becomes noticeably rough when cylinder 2 misfires. Large SUVs display misfire symptoms through cab vibration, rough idle, and hesitation. Check engine light illumination accompanies the misfire condition.
Diagnostic Approach
Comprehensive scanning captures all codes and freeze frame data. Inspect ignition components on cylinder 2. Borescope inspect intake valves for carbon condition. Test fuel injector operation and system pressure. Compression testing verifies mechanical health. Given the newer model year, warranty diagnosis may be beneficial for defect-related issues.
Repair Options
Replace spark plugs and coils as needed with quality components. Carbon cleaning through walnut blasting addresses intake deposits. Fuel injector service ensures proper delivery. Warranty coverage should apply to component defects on the 2022 model year.
