The P0302 diagnostic code on your 2024 Acura RDX indicates that the engine control module has detected cylinder 2 misfires exceeding acceptable thresholds. The RDX's turbocharged powertrain requires careful diagnostic attention.
2024 RDX Powertrain
The 2024 Acura RDX continues with the proven 2.0L turbocharged four-cylinder engine producing 272 horsepower. This direct-injection turbo engine combines performance with efficiency through advanced engine management.
Turbo Engine Dynamics
The turbocharger pressurizes intake air to increase power output. Under boost, cylinder pressures rise significantly, demanding robust ignition. Spark plugs and coils must deliver consistent energy under all conditions. Weak components cause misfires during boost.
Four-Cylinder Impact
Each of the four cylinders produces a quarter of engine power. Cylinder 2 misfires immediately affect drivability—rough idle, hesitation, and vibration are readily apparent. The four-cylinder layout amplifies any single-cylinder issues.
Warranty Coverage
Your 2024 RDX is covered under Acura's comprehensive warranty. Engine misfire diagnosis and repairs should be covered under the powertrain warranty. Contact your dealer to schedule service.
New Vehicle Expectations
Misfires on a new vehicle typically indicate isolated component failures. Acura's quality standards mean systematic problems are rare. The dealer will diagnose and address any defects under warranty.
