5/10
2 catastrophic3 moderate3 minor
The 2024 300 uses the final iteration of the 5.7L HEMI before discontinuation. MDS lifter failure remains the overwhelming concern—forums consistently report 40-60% failure rates by 100k miles. This engine shares the same fundamental architecture and MDS system as 2009-2023 versions, with all associated issues. Overall score reflects a fundamentally sound design compromised by the MDS system and manifold bolt issues. Without MDS, this would be a 7-8/10 engine.
Reliability data pending.
catastrophic55% probability
MDS Lifter Failure
📏 60k–120k mi💵 $4,000–$8,000🏪 Shop only
Multi-Displacement System (MDS) roller lifters fail internally, causing collapsed lifters, damaged camshaft lobes, and metal debris circulation. Often requires complete engine teardown, camshaft replacement, all 16 lifters, and sometimes cylinder head work. This is THE defining failure mode of 5.7L HEMIs from 2009-2024.
Symptoms: loud ticking/tapping at idle · P0300-P0308 misfire codes · MIL illumination · lifter tick that worsens when warm · loss of power
catastrophic12% probability
Valve Seat Recession/Drop
📏 100k–180k mi💵 $3,500–$6,500🏪 Shop only
Exhaust valve seats can separate from the cylinder head casting and drop into the combustion chamber, causing immediate catastrophic damage. More common on pre-2015 HEMIs but still documented on newer variants. Requires cylinder head removal, machining, and valve seat replacement or head replacement.
Symptoms: sudden misfire · catastrophic loss of compression on one cylinder · metallic rattling · P030X codes · potential piston damage if valve contacts piston
moderate35% probability
Exhaust Manifold Bolt Failure/Cracking
📏 40k–90k mi💵 $800–$1,800🏪 Shop only
Exhaust manifold bolts snap due to thermal cycling, or manifolds themselves crack. Very common on 5.7L HEMIs. Bolts are often seized into the head, requiring drilling/extraction. Some require manifold replacement if cracked.
Symptoms: loud ticking or tapping from engine bay · exhaust leak smell · ticking that increases with RPM · visible soot around manifold
moderate25% probability
Oil Consumption
📏 80k–150k mi💵 $2,500–$5,000🏪 Shop only
Piston ring wear or valve guide seal deterioration causes oil consumption of 1qt per 1000-2000 miles. Some engines consume oil from new due to ring seating issues. Chrysler considers 1qt per 2000 miles 'acceptable.' Severe cases require engine teardown, new rings, honing, and valve seal replacement.
Symptoms: low oil level between changes · blue smoke on startup or acceleration · oil burning smell · fouled spark plugs
moderate18% probability
Coolant Crossover Tube Leak
📏 70k–130k mi💵 $600–$1,200🏪 Shop only
Coolant crossover tube under the intake manifold develops leaks at O-ring seals or cracks. Requires intake manifold removal to access. Coolant can leak into valley and cause corrosion or enter oil system in severe cases.
Symptoms: coolant loss with no visible external leak · coolant smell from engine bay · low coolant warning · steam from under intake manifold
minor30% probability
Spark Plug Fouling/Electrode Erosion
📏 30k–60k mi💵 $200–$400🔧 DIY-friendly
Factory spark plugs wear prematurely, especially on MDS-equipped engines. Electrode erosion and carbon fouling on deactivated cylinders. Chrysler service interval is too long for real-world conditions.
Symptoms: misfire codes · rough idle · hesitation · reduced fuel economy · difficulty starting
minor20% probability
Camshaft Position Sensor Failure
📏 60k–120k mi💵 $150–$350🔧 DIY-friendly
Camshaft position sensors fail due to heat exposure and oil contamination. Causes intermittent starting issues and drivability problems. Relatively easy fix but can strand vehicle.
Symptoms: P0340/P0344 codes · intermittent no-start · rough idle · hesitation on acceleration · check engine light
minor15% probability
VVT Solenoid Failure
📏 80k–140k mi💵 $200–$450🔧 DIY-friendly
Variable Valve Timing (VVT) oil control solenoids fail due to contamination or electrical issues. Affects cam phasing and engine performance. Relatively inexpensive repair but can cause drivability concerns.
Symptoms: P0010/P0013 codes · rough idle · reduced fuel economy · check engine light · slight performance loss

Reliability scores and issue probabilities are synthesized from manufacturer TSBs, NHTSA complaints, forum-documented patterns, and instrumented technician reports. Treat as informed estimates, not guarantees — individual vehicles vary widely with maintenance history.
