The 2014 Dodge Charger came with three engine options, each with different fuel economy and maintenance needs

The 2014 Dodge Charger offered three engines: a 3.6-litre V6 producing 292 horsepower, a 5.7-litre V8 producing 370 horsepower, and a 6.4-litre V8 producing 470 horsepower. The V6 was the base engine and delivered the best fuel economy at around 16 to 25 miles per gallon depending on driving conditions and whether you had the automatic or manual transmission. The 5.7-litre V8 returned roughly 15 to 23 mpg, while the 6.4-litre V8 was the thirstiest at 14 to 22 mpg.

All three engines paired with either a five-speed automatic or, on V8 models, a five-speed manual transmission. The automatic was standard across the range. The manual transmission was available only on the V8 models and gave drivers direct control over gear selection, which some owners preferred for performance driving but which required more active engagement on the road.

Engine choice matters for long-term ownership because larger engines consume more oil, require more frequent spark plug changes, and put more stress on cooling systems. The V6 is the most economical choice for daily driving and lower maintenance costs. The V8 engines deliver more power but demand more attention to fluid levels and cooling system health, especially if you live in a hot climate or tow regularly.

Key Takeaways

  • The 2014 Charger's three engines range from a 3.6-litre V6 to a 6.4-litre V8, with fuel economy dropping from 16–25 mpg to 14–22 mpg as engine size increases.
  • Transmission choice is limited: the V6 came with automatic only, while V8 models offered a five-speed automatic or five-speed manual.
  • V8 engines require more frequent oil changes, spark plug service, and cooling system maintenance than the V6.
  • The cooling system is a common wear point on all three engines, particularly on V8 models driven in hot climates or used for towing.

Transmission durability and what to watch for in a used example

The five-speed automatic transmission in the 2014 Charger is a proven design that holds up well when serviced on schedule. Dodge recommended transmission fluid changes every 60,000 miles or every five years, whichever came first. Owners who skip this service often face harsh shifting, delayed engagement, or eventual transmission failure in the 100,000 to 150,000-mile range.

The five-speed manual transmission on V8 models is more robust than the automatic but requires a different kind of attention. The clutch typically lasts 80,000 to 120,000 miles depending on driving style. Aggressive launches, riding the clutch at traffic lights, and frequent towing all shorten clutch life. When the clutch wears, you will notice the engine revving without the car accelerating smoothly, or difficulty engaging first gear from a stop.

When shopping for a used 2014 Charger, ask the seller for transmission service records. If they cannot produce them, budget for a transmission fluid and filter change when ready after purchase. Listen for clunking sounds when shifting from Park to Drive or Reverse—this can signal worn transmission mounts or internal wear. On manual models, test the clutch engagement point by starting from a stop on a slight incline; if the car rolls backward before the clutch fully engages, the clutch is worn.

Cooling system failures are common and expensive if ignored

The 2014 Charger's cooling system is the engine component most likely to fail before 150,000 miles. The plastic radiator tanks and water pump are the weak points. The radiator can develop small cracks in the plastic end tanks, allowing coolant to leak slowly. The water pump bearing can seize, causing the pump to stop circulating coolant and the engine to overheat within minutes.

Preventive maintenance here is straightforward and saves thousands in repair costs. Dodge recommended coolant flushes every 100,000 miles or ten years. Many owners who ignore this end up with a clogged radiator, a failed water pump, or a cracked radiator tank by 120,000 miles. A water pump replacement costs $400 to $700 in labour and parts. A radiator replacement runs $600 to $1,000. An engine overheating event can warp the cylinder head or crack the block, turning a $700 repair into a $3,000 or $4,000 engine replacement.

Check the coolant colour when you inspect a used Charger. It should be bright green, orange, or pink depending on the type Dodge used—never brown or rusty-looking. Brown coolant means rust is building up inside the cooling system, and a flush is overdue. Feel the upper radiator hose when the engine is cold; it should be firm but not rock-hard. A hose that feels soft or spongy is failing and should be replaced before it ruptures.

Spark plugs, ignition coils, and fuel injector maintenance

The 2014 Charger's spark plugs last 100,000 miles on all three engines. At that interval, they should be replaced as a set of six (V6) or eight (V8). Ignition coils, which fire the spark plugs, often fail before the plugs do—typically between 60,000 and 100,000 miles. A failed coil causes a misfire, rough idle, and a check engine light. Replacing one coil costs $150 to $300 in labour and parts.

Fuel injectors on the 2014 Charger rarely fail outright but can become clogged with carbon deposits, especially if the car sits for long periods or uses low-quality fuel. Clogged injectors cause hesitation during acceleration, poor fuel economy, and rough idle. A fuel system cleaning service costs $100 to $200 and can restore performance. If cleaning does not work, individual injector replacement runs $200 to $400 per injector.

Keep receipts for spark plug and coil replacements. These are wear items, and knowing when they were last serviced helps you plan future maintenance. If you buy a used Charger with over 80,000 miles and no service records for ignition components, budget for coil inspection and possible replacement within the first year of ownership.

Suspension and steering components wear faster on V8 models

The 2014 Charger's suspension uses a double-wishbone front end and a multi-link rear. The heavier V8 engines put more load on these components, causing faster wear. Front struts typically last 60,000 to 80,000 miles on a V6 but only 50,000 to 70,000 on a V8. Rear shocks follow a similar pattern. When struts fail, you will notice a bouncy ride, nose-diving under braking, or clunking sounds over bumps.

Steering components also wear faster on V8 models. The steering rack, tie rods, and ball joints all experience more stress. A worn tie rod causes a clunking sound when turning or a wandering feeling at highway speeds. Ball joint wear shows up as a clicking sound during turns or a loose, vague steering feel. These repairs are not optional—worn steering components affect your ability to control the car and can lead to sudden loss of steering.

Suspension and steering work should be done by a shop with alignment equipment. After any suspension repair, the front end must be aligned to prevent uneven tyre wear and pulling to one side. Alignment costs $100 to $200 but prevents $500 in premature tyre replacement.

Brake system maintenance and pad wear patterns

The 2014 Charger came with four-wheel disc brakes. Front brake pads typically last 40,000 to 60,000 miles depending on driving style and whether the car is driven mostly on highways or in stop-and-go city traffic. Rear pads last longer, usually 60,000 to 80,000 miles. V8 models, which are heavier and more powerful, often see faster front pad wear because they carry more weight and generate more heat during braking.

Brake fluid should be flushed every two years or 30,000 miles. Brake fluid absorbs moisture from the air, and old fluid can cause the brake pedal to feel spongy or soft. A brake fluid flush costs $100 to $150 and prevents corrosion inside the brake lines and calipers. Ignoring this maintenance can lead to brake line rust and eventual brake failure.

When you inspect a used Charger, look at the brake rotors. They should be smooth and shiny, not scored or pitted. Scored rotors mean the pads wore down to the backing plate and metal-on-metal contact occurred. Replacing rotors and pads together costs $400 to $600 per axle. If only pads are replaced on scored rotors, the new pads will wear out quickly and the problem will repeat.

Electrical system quirks and battery life

The 2014 Charger's electrical system is generally reliable, but a few components show up in owner complaints. The alternator can fail between 80,000 and 120,000 miles, leaving you with a dead battery and no charging. A replacement alternator costs $400 to $600 in labour and parts. The battery itself typically lasts three to five years regardless of mileage, so a used Charger with an original battery older than five years should have the battery tested or replaced before you rely on it for daily driving.

The door locks and power window motors can fail prematurely on some examples, though this is not universal. A power window motor replacement runs $200 to $400 per window. Door lock actuators cost $150 to $300 to replace. These are convenience items, not safety concerns, but they are worth knowing about when budgeting for ownership.

Check all lights—headlights, taillights, interior lights, and dashboard illumination—when you test-drive a used Charger. Burnt-out bulbs are cheap to replace, but multiple failures can signal an electrical system problem. Test the power windows, locks, and seat adjusters. These give you a sense of how well the previous owner maintained the car's electrical systems.

Frequently Asked Questions

What is the difference in maintenance cost between the V6 and V8 models?

The V8 models cost more to maintain because they use more oil, require more frequent spark plug and coil service, and put more stress on cooling and suspension systems. Expect V8 maintenance to run 20 to 30 percent higher than V6 maintenance over the same mileage interval. Oil changes are more frequent, and larger components like radiators and water pumps are more expensive to replace.

How often should I change the oil in a 2014 Charger?

Dodge recommended oil changes every 10,000 miles or one year, whichever came first. Some owners stretch this to 15,000 miles using synthetic oil, but the owner's manual should be your guide. V8 engines benefit from more frequent changes because they generate more heat and wear on the oil. Skipping oil changes is the fastest way to shorten engine life.

Is the manual transmission reliable, or should I avoid it?

The five-speed manual is reliable if the clutch is treated well. Avoid cars where the seller admits to aggressive driving or frequent towing. Test the clutch by starting on an incline; if it slips or the car rolls backward, the clutch is worn and replacement will cost $1,000 to $1,500. For daily driving, the automatic is less demanding and requires no clutch management.

What should I look for when buying a used 2014 Charger?

Request service records for transmission fluid, coolant, spark plugs, and brake fluid changes. Check the coolant colour and radiator hose condition. Listen for coil pack misfires during cold start. Test the suspension by bouncing each corner—it should settle quickly, not bounce repeatedly. Inspect brake rotors for scoring. A car with complete service records and no warning lights is worth more than one with gaps in maintenance history.

Can I tow with a 2014 Charger?

The 2014 Charger is not designed for towing. Dodge did not publish a towing capacity for this model, and the suspension, transmission, and cooling system are not engineered for the stress of pulling a trailer. Towing will accelerate wear on the transmission, cooling system, and suspension components. If you need a tow vehicle, choose a truck or SUV built for that purpose.
