The 2009 Charger is a full-size sedan with a V8 engine and rear-wheel drive, built on a platform shared with the Chrysler 300

The 2009 Dodge Charger came in three main engine options: a 2.7-liter V6 producing 178 horsepower, a 3.5-liter V8 with 250 horsepower, and a 5.7-liter V8 with 370 horsepower in the R/T model. The base model and SE trim used the V6; the SXT and Magnum trims offered the 3.5-liter V8; the R/T came exclusively with the 5.7-liter. All versions paired with a five-speed automatic transmission and sent power to the rear wheels.

This generation Charger (2006–2010) was heavier and more powerful than its predecessor, weighing between 3,800 and 4,000 pounds depending on engine and trim. The 2009 model year was essentially unchanged from 2008, with the same interior layout, suspension geometry, and brake system. If you own one or are considering buying one, understanding what's under the hood matters for maintenance planning and repair costs.

Key Takeaways

  • The 2009 Charger used either a 2.7L V6, 3.5L V8, or 5.7L V8, and the engine choice determines fuel economy, maintenance intervals, and repair expense.
  • All 2009 Chargers are rear-wheel drive with a five-speed automatic transmission, which affects handling in snow and winter driving safety.
  • The 5.7L V8 R/T model requires premium fuel and has higher insurance and fuel costs than the V6 or 3.5L V8 versions.
  • Common wear items on this generation include the transmission fluid, spark plugs, and suspension bushings, which should be inspected regularly to prevent larger repairs.

Engine options and what they mean for fuel economy and maintenance

The 2.7-liter V6 was the base engine and delivered the best fuel economy of the three, though still modest by modern standards—roughly 17 miles per gallon in the city and 25 on the highway. This engine was simpler and had fewer moving parts than the V8 options, which generally meant lower repair costs when something broke. However, the V6 was also the least powerful, and some owners reported that it felt underpowered when towing or accelerating on highways with traffic.

The 3.5-liter V8 split the difference: more power than the V6 but better fuel economy than the 5.7L, with city/highway figures around 16/24 mpg. This engine was a solid middle ground for owners who wanted V8 performance without the premium fuel requirement or the highest insurance premiums. Maintenance intervals were the same as the 5.7L, but the smaller displacement meant slightly lower stress on internal components.

The 5.7-liter V8 in the R/T was the most powerful but also the thirstiest, returning roughly 15/23 mpg. This engine required premium (91 octane or higher) fuel, which added to the cost of ownership. The 5.7L also had tighter tolerances and higher compression, meaning spark plugs, oil changes, and transmission fluid became more critical to longevity. If you own a 5.7L R/T, skipping scheduled maintenance is more likely to cause expensive problems than it would on the V6 or 3.5L.

Transmission and drivetrain durability

All 2009 Chargers used a five-speed automatic transmission (Chrysler's 5G-Tronic). This transmission was generally reliable but had a known weakness: the transmission fluid could break down faster than expected if the vehicle was driven in heavy traffic, towing, or hot climates. Owners who ignored transmission fluid changes sometimes experienced slipping, delayed shifts, or complete failure by 100,000 miles.

The rear-wheel-drive layout meant the Charger could be difficult to control in snow or ice without proper winter tires and careful driving. Unlike front-wheel-drive sedans, a Charger's rear end can slide out if you accelerate too hard on slippery surfaces. This is not a defect—it is how rear-wheel-drive cars behave—but it matters for safety and for understanding what kind of driving this car is suited for.

The rear differential used in the 2009 Charger was robust, but the differential fluid should be changed every 50,000 to 60,000 miles if you tow or drive in severe conditions. Many owners neglected this, and worn differential fluid led to noise and eventual gear damage. If you hear a whining sound from the rear of the car that gets louder when you accelerate, have the differential fluid checked when ready.

Suspension, steering, and brake system maintenance

The 2009 Charger used a double-wishbone front suspension and a live axle rear suspension, a setup that was durable but prone to wear in the bushings and ball joints. The rubber bushings that connect the suspension arms to the frame deteriorated over time, especially in vehicles driven in cold climates or on rough roads. Worn bushings caused clunking noises when turning or going over bumps, and they reduced steering precision.

The steering system used a hydraulic power steering pump, not the electric systems found in newer cars. This pump was reliable but could develop leaks or noise as it aged. If you notice a whining sound when you turn the wheel, or if the steering feels stiff, the power steering fluid level should be checked and the pump may need service.

The brake system used four-wheel disc brakes with an anti-lock braking system (ABS). The brake pads and rotors wore at a normal rate, but some owners reported that the ABS module could fail, causing the ABS warning light to stay on. This did not prevent the brakes from working, but it meant the anti-lock function was unavailable. Replacing an ABS module was expensive, so if you see that warning light, have it scanned to confirm the problem before assuming the worst.

Common electrical and cooling system issues

The 2009 Charger had a relatively straightforward electrical system by modern standards, but a few components were known to fail. The alternator could wear out by 80,000 to 100,000 miles, especially in vehicles that spent a lot of time idling or running accessories like air conditioning. A failing alternator would not charge the battery fully, causing the battery to drain and the car to stall.

The cooling system used a serpentine belt to drive the water pump and alternator. This belt should be inspected every 30,000 miles and replaced by 60,000 to 100,000 miles, depending on the condition. A broken serpentine belt would cause the engine to overheat within minutes, so this is not a repair to delay. The water pump itself could fail, and when it did, coolant would leak into the engine oil, requiring an engine rebuild in the worst cases.

The radiator and heater core were aluminum and prone to corrosion if the coolant was not changed regularly. Chrysler recommended changing the coolant every 30,000 miles or three years, whichever came first. Owners who went longer between changes sometimes found that the radiator or heater core had corroded internally, restricting coolant flow and causing overheating.

Interior and exterior durability

The 2009 Charger's interior was straightforward and held up reasonably well, but the dashboard plastic could crack in hot climates, and the door panels sometimes developed rattles. The power windows and locks were generally reliable, though the window regulators could wear out by 100,000 miles. The seats were cloth or leather depending on trim, and the leather could crack if not conditioned regularly.

The exterior paint was prone to fading and peeling on the hood and roof, especially on vehicles exposed to intense sun. The clear coat could separate from the base coat, requiring a repaint to restore appearance. The door seals and weatherstripping deteriorated over time, allowing water to leak into the doors and trunk. If you notice water pooling inside the car after rain, the weatherstripping should be replaced.

Fuel system and emissions components

The fuel pump in the 2009 Charger was located inside the fuel tank and could fail without warning, leaving you stranded. Some owners reported fuel pump failure around 80,000 to 120,000 miles. If the car cranks but does not start, and you hear no whirring sound from the fuel tank when you turn the key to the "on" position, the fuel pump may be dead.

The emissions system included a catalytic converter, which could become clogged if the engine was burning oil or running rich. A clogged converter would cause the check engine light to come on and reduce engine performance. Replacing a catalytic converter was expensive, so keeping the engine tuned and addressing oil leaks quickly was important for avoiding this repair.

Frequently Asked Questions

How often should I change the oil in a 2009 Charger?

Chrysler recommended oil changes every 3,000 miles or three months for the 2009 Charger, though some owners stretched this to 5,000 miles with synthetic oil. The 5.7L V8 benefited from more frequent changes because of higher combustion pressures. Check your owner's manual for the exact interval and oil grade your engine requires.

What is the towing capacity of a 2009 Charger?

The 2009 Charger was not designed for towing, and Dodge did not publish a towing capacity. Attempting to tow with a Charger could damage the transmission and rear axle. If you need to tow, a truck or SUV is the appropriate vehicle.

Why does my 2009 Charger shake when I brake?

Shaking during braking usually means the brake rotors are warped or the brake pads are worn unevenly. This is a safety issue and should be addressed when ready. Have the brakes inspected and the rotors replaced if necessary. Do not ignore brake problems.

Is the 2009 Charger a good used car to buy?

The 2009 Charger is a solid used car if it has been maintained, but it is not fuel-efficient and repair costs can be high, especially for the 5.7L V8. Look for service records showing regular oil changes, transmission fluid service, and suspension maintenance. Avoid vehicles with high mileage or unknown maintenance history.

What does the check engine light mean on a 2009 Charger?

The check engine light indicates a problem with the engine, emissions system, or transmission. Common causes include a loose gas cap, a faulty oxygen sensor, or a catalytic converter issue. Have the car scanned with a diagnostic tool to read the fault code and determine the cause. Continuing to drive with the light on can cause more damage.
