The 2015 Dodge Charger SXT is a mid-range four-door sedan with a V8 engine, front-wheel drive, and room for five passengers
The 2015 Charger SXT sits between the base SE model and the higher-performance R/T trim. It comes standard with a 3.6-liter V8 engine producing 292 horsepower and 260 pound-feet of torque, paired with an eight-speed automatic transmission. This engine and transmission combination is the same across most 2015 Charger trims, so the SXT gives you the V8 power without paying for the R/T's upgraded suspension and brakes.
The SXT includes air conditioning, power windows and locks, cruise control, and a 5-inch touchscreen with Bluetooth connectivity. Cloth seats come standard, though leather is available as an option. The car seats five adults and has a 16.2-cubic-foot trunk. Fuel economy is rated at 16 mpg city and 25 mpg highway by the EPA, which is typical for a V8 sedan of this size and weight.
Key Takeaways
- The 2015 Charger SXT uses a 3.6-liter V8 engine with 292 horsepower, the same powerplant found in most other 2015 Charger models.
- Standard features include air conditioning, power windows and locks, Bluetooth, and a 5-inch touchscreen, with leather seats available as an upgrade.
- Fuel economy averages 16 mpg city and 25 mpg highway, which is normal for a full-size V8 sedan but means regular fill-ups at the pump.
- The SXT uses the same brakes and suspension as the base SE model, so it handles like a standard Charger rather than the sportier R/T.
- Common maintenance items include spark plugs every 30,000 miles, transmission fluid checks every 60,000 miles, and coolant replacement at 100,000 miles.
Engine and Transmission Details
The 3.6-liter V8 in the 2015 SXT is a workhorse engine that Dodge used across multiple models and model years. It produces enough power for highway merging and passing without the fuel consumption penalty of the larger 5.7-liter Hemi V8 found in the R/T. The engine uses a timing chain rather than a timing belt, which means it does not require replacement at a set interval—a timing chain typically lasts the life of the engine if oil changes are done on schedule.
The eight-speed automatic transmission shifts smoothly in normal driving and allows the engine to run at lower RPMs on the highway, which helps with fuel economy. This transmission is reliable when maintained properly. Transmission fluid should be checked every 60,000 miles and replaced according to your owner's manual, which typically calls for a change somewhere between 60,000 and 100,000 miles depending on driving conditions. Neglecting transmission fluid changes is one of the fastest ways to shorten the life of this transmission.
Fuel Economy and Real-World Driving Costs
The EPA rating of 16 mpg city and 25 mpg highway is honest but not generous. Real-world fuel economy depends heavily on how you drive. Aggressive acceleration, frequent idling, and highway speeds above 65 mph will push consumption closer to 15 mpg overall. Steady, moderate driving on the highway can sometimes reach 26 or 27 mpg. Most owners report averaging 19 to 21 mpg in mixed driving.
At current fuel prices, this means budget roughly $200 to $250 per month for fuel if you drive 12,000 miles per year—the national average. If you drive more, or if fuel prices rise, that number climbs. The SXT requires regular unleaded gasoline (87 octane), not premium, so you are not paying extra at the pump for fuel grade. Keeping the engine properly tuned, the air filter clean, and the tires inflated to the correct pressure will help you stay on the better end of that fuel economy range.
Brakes, Suspension, and Handling
The 2015 Charger SXT uses four-wheel disc brakes with electronic brake force distribution and stability control. The brakes are adequate for a car this size and weight, but they are not the upgraded performance brakes found on the R/T. Brake pads typically last 25,000 to 70,000 miles depending on driving style—aggressive braking wears them faster. Rotors often last twice as long as pads, though they may need resurfacing or replacement when pads are changed.
The suspension uses a double-wishbone front end and a multi-link rear, which is a solid setup for a full-size sedan. The SXT does not have the stiffer springs and shocks of the R/T, so it rides more smoothly over bumps but leans more in corners. This is not a sports car, and the suspension reflects that. Struts and shocks typically need replacement between 50,000 and 80,000 miles, though some last longer. If you notice the car bouncing after bumps or leaning heavily during turns, have the suspension inspected.
Common Maintenance and Wear Items
The 2015 Charger SXT follows a standard maintenance schedule. Oil and filter changes are due every 10,000 miles or annually, whichever comes first. Spark plugs should be replaced at 30,000 miles. The air filter needs inspection every 15,000 miles and replacement when it becomes visibly dirty—this is usually every 30,000 to 45,000 miles depending on driving conditions. The cabin air filter, which cleans the air entering the cabin through the heating and air conditioning system, should be replaced every 12,000 to 15,000 miles.
Coolant should be flushed and replaced at 100,000 miles. Brake fluid should be inspected annually and replaced every two years, as it absorbs moisture from the air and loses effectiveness over time. The transmission fluid, as mentioned earlier, needs checking at 60,000 miles and replacement according to your owner's manual. Tire rotation every 7,500 miles helps them wear evenly and last longer. Most tires last 25,000 to 50,000 miles before needing replacement, depending on driving habits and road conditions.
Interior Features and Comfort
The SXT interior is straightforward and functional. The 5-inch touchscreen handles audio, Bluetooth phone calls, and basic vehicle settings. It is not a large screen by modern standards, but it is responsive and straightforward to navigate while driving. The steering wheel is adjustable for both tilt and telescoping, so you can find a comfortable driving position. Power windows and locks are standard, and the air conditioning is effective in hot weather.
Cloth seats are standard on the SXT, and they are durable and straightforward to clean. Leather seats are available as an option and add a more upscale feel, though they require occasional conditioning to prevent cracking. The back seat has decent legroom for adults on short trips, though the Charger is not as spacious as some competing sedans. Storage cubbies are scattered throughout the cabin, and the 16.2-cubic-foot trunk is large enough for groceries, luggage, or tools.
Safety Features and Crash Test Ratings
The 2015 Charger SXT comes with electronic stability control, traction control, and a backup camera as standard equipment. These systems help prevent skids and loss of control in emergency maneuvers. The backup camera displays on the touchscreen and makes parking in tight spaces easier. Anti-lock brakes prevent wheel lockup during hard braking, which helps maintain steering control in emergency stops.
The National Highway Traffic Safety Administration (NHTSA) tested the 2015 Charger and gave it four stars overall, with four stars in frontal crash and rollover tests and five stars in side crash. The Insurance Institute for Highway Safety (IIHS) rated it "Good" in most crash tests. These ratings indicate the car provides reasonable protection in accidents, though no car is crash-proof. Airbags are standard throughout the cabin—dual front, side-impact, and curtain airbags protect occupants in various types of collisions.
Reliability and Known Issues
The 2015 Charger SXT is generally reliable when maintained on schedule. The 3.6-liter V8 engine is proven and durable. The eight-speed transmission is solid if fluid changes are not skipped. Some owners have reported issues with the touchscreen freezing or becoming unresponsive, though this is not universal and often resolves with a software update. A small number of owners have experienced water leaks around the door seals in heavy rain, which can be addressed by a dealer.
The most common wear items are brakes, tires, and suspension components—all normal for a car of this size and age. If you are considering a used 2015 Charger SXT, have a pre-purchase inspection performed by a trusted mechanic. They can check the condition of the brakes, suspension, and transmission fluid, and listen for any unusual engine noises. A well-maintained example with full service records is a solid choice for a used full-size sedan.
Frequently Asked Questions
What is the difference between the SXT and the R/T?
Both use the same 3.6-liter V8 engine, but the R/T adds a stiffer suspension, upgraded brakes, a performance-tuned transmission, and sportier styling. The R/T handles better in corners and stops more quickly, but costs more and gets slightly worse fuel economy. The SXT is the practical choice if you want V8 power without the performance package.
How often do I need to change the oil?
Every 10,000 miles or annually, whichever comes first. Use the oil grade specified in your owner's manual—typically 5W-20 for the 3.6-liter V8. Skipping oil changes is the fastest way to damage the engine, so do not delay.
Can I tow a trailer with a 2015 Charger SXT?
The Charger is not designed for towing. It lacks the transmission cooler, reinforced frame, and hitch hardware needed for safe trailer towing. Use a truck or SUV if you need to tow regularly.
What should I look for when buying a used 2015 Charger SXT?
Check the service records to confirm oil changes were done on schedule. Have a mechanic inspect the brakes, suspension, and transmission fluid condition. Listen for any knocking or grinding sounds from the engine. Ask about any previous accidents or damage repairs. A well-maintained example is a good value in the used sedan market.
Is the 2015 Charger SXT good on gas?
No. At 16 mpg city and 25 mpg highway, it is average for a V8 sedan but below average for cars overall. If fuel economy is your priority, a four-cylinder sedan or hybrid will cost significantly less to operate.
