2014 Ford Fusion Rattling Noise – Some Reasons

We discussed the problem of Ford ST clicking sound in the previous post. Thus the problem that has to be fixed in this post is 2014 Ford Fusion rattling noise.

You should avoid hearing anything rattle while driving. The first thing you should check if there is anything rattling about in your cup holder, or trunk of your car. If you hear rattling noises while driving is to make sure that nothing is rattling. 

After ruling it out, you may start investigating the source of the rattling and how an auto repair company can stop it. 

Because no two rattles are exactly the same, figuring out the rattle’s probable cause requires a little more science.

Therefore, you can begin to determine the source of the rattle. Besides you can define how much it will cost to remedy it by listening to the rattle itself and the area from which it appears to be emanating.

Here are a few typical explanations for why your automobile can be making a rattling noise.

Reasons Why 2014 Ford Fusion Rattling Noise?

There are numerous reasons why your Ford Fusion is shaking. The issue exists inside, outside, and even beneath the vehicle. Here are some reasons to remember:

From Inside Your Ford Fusion

One reasonable approach to problem diagnostics is to move from little, easily-fixed problems to larger ones. Before you start on intricate and expensive repairs, rule out the easy remedies.

The simple, straightforward problems that cause rattles when your motor is idle are frequently located within the automobile rather than in the engine compartment or the driveline.

The good news is that any interior shaking is probably caused by a little problem that you can probably remedy.

An object resting in the door panel pocket or cup holder might also start rattling at idle, as can a loose center console lid or broken glove box hinge.

Therefore, if you hear rattling, thoroughly check the inside, including the cargo area or trunk. Some cars include cargo-carrying mechanisms and cargo coverings that can be the cause of rattles that you might only hear while the sound system is off and the car is idling.

In general, the solutions to these issues are obvious, and you may complete them with just a screwdriver, a pair of pliers, or no tools at all.

Take your car to a garage so they can check for any underlying issues if you can’t locate an obvious source of the noise.

From Under Your Ford Fusion

If you have examined every interior component that might jangle and still can’t locate the noise’s source, it’s likely coming from somewhere else inside the car.

It is a safe guess that the noise is coming from under the car, possibly directly under the passenger compartment, if it seems like the rattling is coming from the interior but you haven’t discovered any loose interior parts.

The emissions and exhaust systems are two typical origins of these unsettling noises. Once more, it’s a good idea to start by looking at the least expensive issues, and in this case, the heat shield issue is the least expensive issue. 


Your exhaust system most certainly needs to be repaired if the rattling noise seems to be coming from underneath your car.

One of the most frequent causes of the rattling sound that your Ford Fusion’s engine makes is the exhaust system. Despite the exhaust being external to the engine, it frequently produces sounds that are mistaken for internal engine rattles.

Catalytic converter troubles, muffler problems, or rusted pipes are examples of exhaust system concerns. They might cause your car to shake or sound like rocks are under your car. When you are stopped at a signal or stop sign or in heavy traffic, exhaust system issues are more obvious.

Failing Catalytic Converter

A malfunctioning catalytic converter is another reason why the car shakes below. The most harmful substances and components are taken out of the exhaust gases by a catalytic converter, which is an essential component of the exhaust emissions system. 

Its core has a honeycomb-like structure, and in its extremely hot surroundings, it converts unburned gases into less dangerous components.

The problem is that when the core deteriorates over time, little parts will fall out and start to rattle inside the catalytic converter shell. 

If this happens, the catalytic converter needs to be replaced since if it doesn’t it will eventually clog and stop working. You will fail your subsequent smog test in addition to having your automobile run improperly.

Exhaust Leak

Your exhaust system will frequently rattle loudly and aggressively if it is leaking. It’s been referred to as a rattle by some people. If it is leaking, the exhaust manifolds where it bolts to the block are where it will likely leak from most frequently. 

Check to see if any of the bolts holding the exhaust manifold together have come loose. This occurs frequently in all automobiles.

From Under Fusion Bonnet

The bonnet cap cannot be ignored when testing for problems. Here are a few causes of rattling noises.

Low Engine Oil

The engine oil level should be checked first if you hear rattling coming from under the hood of your Fusion. Your engine may rattle if there isn’t enough oil moving through it because different sections will scrape against one another without enough lubrication. To prevent significant damage, top off your oil as needed.

Damaged Serpentine Belt or One with Cracks

The alternator, AC compressor, and water pump in your car are all driven by a serpentine belt. If you’re not sure how to distinguish between a timing belt and a serpentine belt, you should know that the latter is typically concealed by covers.

The best thing you can do is open up the bonnet, have a look, and decide whether you can drive the car to a repair yourself or whether it needs to be towed because if you drive your car with a damaged or broken timing belt, the engine will overheat.

From Under Fusion Hood

The next logical place to search is under the hood after you’ve ruled out the interior and underbody of the automobile as the rattle’s origins. Sadly, this is where rattles cause their most expensive issues.

A malfunctioning hydraulic valve lifter is one typical issue that will generate a rattling when the engine is idle. By using oil pressure, the lifters, small components, open and close the engine valves.

Despite having incredibly complex valve systems, many of which feature variable valve timing, today’s cars are frequently quite trouble-free.

However, hydraulic lifters are known to fail in older cars and to rattle when they do so.

If this is the issue, you should replace every lifter in the set because if one has failed, others are probably not far behind.

When you start the engine of your car, a rattle could be a sign of piston slap. A close fit between the piston and cylinder wall allows pistons to rise and fall in their cylinders.

The pistons won’t move correctly in the cylinder if that small gap increases due to wear and tear; this results in the noise that mechanics refer to as “piston slap.”

Even while the issue might only affect one cylinder-piston set, it is more likely that several are compromised. This is a serious issue that necessitates an entire engine rebuild.

Final Thoughts

The issues that can cause rattling sounds have been thoroughly discussed. You can consult with a mechanic to determine the reason for your car’s problems. If you are not a mechanic, we recommend that you take your vehicle to a repair shop so that the specialists can assist you. Your bill could be several feet longer if you tamper with it yourself and make the wrong fixes.
