What to Do About a Dodge Charger Cylinder 5 Misfire: Causes and Symptoms in 2013, 2016, and 2018 Models

If your Dodge Charger is showing signs of a cylinder 5 misfire, you’ve probably noticed rough idling, loss of power, or the dreaded check engine light. The problem can affect various Charger model years—including 2013, 2016, and 2018—and is usually triggered by issues with the ignition, fuel, or engine internals. Addressing the misfire quickly prevents further damage and keeps your Charger running smoothly. Let’s break down what causes a cylinder 5 misfire, the symptoms to watch for, and how to handle it in different model years.

What Are the Most Common Symptoms of a Dodge Charger Cylinder 5 Misfire?

The telltale signs of a cylinder 5 misfire in your Dodge Charger usually include a rough engine idle, reduced acceleration, shaking or vibration, and a persistent check engine light—often with the P0305 code. These symptoms may also appear as inconsistent engine performance or a noticeable drop in fuel economy.

If you’re experiencing any of these signs, your Charger’s fifth cylinder isn’t firing as it should. Misfires are often first noticed at low idle—like waiting at a red light—where the engine feels rough or unsteady. According to real Dodge owners discussing their experiences, a cylinder 5 misfire frequently triggers the P0305 code and rough idle. Sometimes the misfire is subtle, so pay attention if you feel a pulsing sensation while driving or accelerating.

Left unchecked, a misfire can quickly lead to additional issues like engine damage or catalytic converter failure, so quick diagnosis is essential. Don’t ignore prolonged roughness or a steadily glowing check engine light.

What Are the Typical Causes of Cylinder 5 Misfire in Dodge Charger Models?

The most common root causes of a cylinder 5 misfire include faulty spark plugs, ignition coils, bad fuel injectors, vacuum leaks, or internal engine problems like worn valves or camshaft components. Sometimes it’s as simple as a loose connection; in other cases, you may be dealing with a deeper mechanical fault.

Experts and mechanics often find that fuel injector, valve, and cam issues are major suspects for misfires in Dodge Chargers. For model years like 2013, 2016, and 2018, ignition coil or plug failure is also quite common. Diagnosis starts with a scan tool to identify the trouble code, then checking each potential source one by one.

Leaking vacuum hoses or intake gaskets can also throw off the air-fuel mixture for cylinder 5, leading to incomplete combustion. Don’t rule out issues like worn piston rings or lifters, especially if your Charger has higher mileage. Systematic testing and elimination will help zero in on the cause.

How Should You Diagnose a Cylinder 5 Misfire in a Dodge Charger?

Start by connecting an OBD-II scanner to your Dodge Charger to confirm the P0305 code or related misfire alerts. Once you know cylinder 5 is involved, begin with the basics: inspect the spark plug in cylinder 5 for signs of fouling or wear, and check the ignition coil by swapping it with another cylinder to see if the misfire moves.

If the ignition system checks out, move on to the fuel injector—listen for clicking sounds or use a noid light to test for electrical pulses. Don’t forget to check for vacuum leaks and inspect hoses near cylinder 5. Visual checks for wiring harness issues or physical engine damage may also be necessary for thorough troubleshooting.

A YouTube guide explains that misfires can sometimes be traced to air or fuel issues, making a simple fix possible with basic diagnostics. Remember, a systematic approach will save you time and money, so follow a logical order from simple to complex causes.

If you are unsure at any step, a professional mechanic or dealership technician can efficiently pinpoint the source using specialized tools and experience, which may be worth the investment—especially if the misfire proves stubborn.

Are There Any Differences in Cylinder 5 Misfire Issues Across 2013, 2016, and 2018 Chargers?

Most symptoms and causes of a cylinder 5 misfire are similar from year to year, but small mechanical and electronic changes can affect how the problem develops or is fixed. For example, the ignition system and fuel injector designs evolved slightly between the 2013 and 2018 models, which may change which component is most likely to fail first.

2013 Chargers frequently experience misfires due to ignition coil or plug failure, as well as common issues with the 3.6L Pentastar engine. Later years like 2016 and 2018 may have revised coil pack designs or updated engine control modules, which can alter the typical diagnostic approach or repair parts needed.

Reading through owner reports and technical forums reveals that certain model years may develop misfire problems at lower mileage, especially if the vehicle has seen mostly city driving or inconsistent maintenance. If you’re troubleshooting your Charger, always look up model-specific service bulletins or known issues for your exact year and engine.

What Steps Can You Take to Prevent Cylinder 5 Misfires in Your Dodge Charger?

Prevention is mostly about routine maintenance—changing spark plugs and ignition coils according to the manufacturer’s schedule, cleaning or replacing fuel injectors, and staying vigilant for vacuum leaks and abnormal engine noise. Using recommended fuel and performing regular oil changes go a long way.

Catch problems early by paying attention to changes in how your Charger drives or idles. If you notice a new engine vibration or sluggish response, don’t wait for the check engine light. Get ahead of the issue with a quick scan and inspection.

Make sure to use quality, OEM or equivalent parts for any repairs. Cheap or off-brand ignition components can actually worsen the problem or cause other cylinders to misfire in the future. When in doubt, consult trusted mechanics or local forums—many modern Charger owners share detailed experiences and tips for keeping these engines healthy.

Taking these steps seriously will help you enjoy a smoother, more reliable Dodge Charger, no matter the model year. Early action and careful diagnosis make all the difference.
