Rattling noise is very common, and if your vehicle rattles when accelerating, you're not alone because many people out there are suffering from the same problem. The question remains, what are the most common places your car rattles while accelerating? And how to fix it?
This article provides all you need to know about the 12 places your car rattles while accelerating. It also highlights recommendations on repair options and repair costs.
12 places your car rattles while accelerating
When your vehicle rattles while accelerating, it's not a normal situation, and you should never ignore it. The more you ignore the problem, the more complicated it gets and the higher the repair costs.
Typically, your car will rattle while accelerating if you have one of the following problems:
1. Broken engine mount
The first and most common issue that results in your vehicle rattling while accelerating is when you have a broken or damaged engine mount. The engine should sit in place and doesn't move, but the mounts might wear out over time and cause the engine to make some rattling noises.
Typically, if the problem is related to an engine mount, you should notice that the rattling noise comes from under the hood and from the location of your engine. If that's the case, your mechanic needs to perform a thorough inspection and confirm that one or more of the mounts are damaged to repair them and fix them.
2. Damaged heat shield
In some other scenarios, you might deal with a problem other than those related to the engine mounts. For example, a small piece of metal designed specifically to protect engines from heat is referred to as a heat shield.
Obviously, the heat shield does not exist in every vehicle, but if your car has a heat shield that gets damaged, you might start noticing some rattling noises, especially when you accelerate.
3. Low motor oil
Your motor oil is one of the most critical fluids in your vehicle that's responsible for preventing internal friction and engine overheating. Overtime we've used, this oil might leak for various reasons, but when it leaks, it leads to engine problems.
A common noise you're insured might start making when your engine oil is low is a rattling noise while accelerating.
You, as a driver, must understand that little motor oil is never in good condition. Your goal should be to eliminate the rattling noise and figure out why you have a low engine oil.
Your mechanic might find internal or external locations where your vehicle started leaking oil, and that's where you have to fix them before that problem gets more complicated.
4. Malfunctioning timing belt
Another potential reason and place where your car rattles while accelerating is when you have a problem with the timing belt. This belt is a core component in your engine, and when it is overstretched or has some issues, it will cause your vehicle to make a rattling noise.
It's important for you as a driver to figure out why the timing belt is overstressed and have your mechanic resolve it before the timing belt breaks out. When the timing belt breaks out, it leads to further complications that might impact more expensive components and cost you thousands of dollars on repair.
5. Damaged piston ring
If you confirm that the timing belt and the previously mentioned components are in good condition, the next step is to look at the piston rings. These are smaller components inside the engine itself, and if worn out, they might lead to some rattling noises, especially if one is disconnected or broken completely.
Damaged piston rings are never fun because they lead to significant repairs, and the more you wait on them, the more complicated the problem gets. Unfortunately, fixing the damaged piston rings is not something you can do on your own; therefore, you need to consider potential payments for labor costs and parts costs.
6. Malfunctioning catalytic converter
In some serious scenarios, your vehicle might suffer from rabbit Ling noises because of a problem with the catalytic converter.
The catalytic converter is responsible for clearing and converting the bad gases generated through combustion into less harmful gases. When the catalytic converter fails, it stops doing its job and can easily lead to some additional rattling noises every time you accelerate.
7. Damaged flywheel
If you are lucky enough and neither the piston rings nor the catalytic converter goes bad, the other thing to check is the flywheel. The flywheel can get damaged for various reasons, including those related to normal vehicle aging.
It is important that when the flywheel is about to fail or it fails that you replace it immediately. The longer you wait and the problem, the more complication happens and the more chances you get involved in critical risky situations.
8. Problematic timing belt pulley
In some scenarios, the timing belt itself might be all right. Instead, you might be dealing with an issue related to the pulley connected to the timing belt.
Your mechanic needs to confirm whether the timing belt pulley has a problem. Once this is confirmed, he needs to replace it immediately before problems get to additional components that also require replacement.
9. Malfunctioning in the interior trim
If you confirm that the pulley is in good condition, the next step is to look at the interior trim. The trim might fill out for various reasons, and you, as a driver, should be able to detect it by taking a visual inspection and confirming it's in good condition.
Your mechanic can also look at the trim and confirm whether it's damaged or loose. If you're lucky, you might be just dealing with a loose trim that needs tightening, which shouldn’t cost you much. However, in some severe scenarios, the interior trim might be broken, requiring a complete replacement.
10. Bad water pump
Did you know that a bad water pump might also cause your vehicle to rattle while accelerating? Therefore, if you're still looking for places your car rattles while accelerating, you should consider inspecting the water pump.
The water pump is a critical component in your cooling system and is responsible for pumping coolant around the engine when it overheats. A failing water pump can lead to further complications that could cause the entire engine to too.
Therefore, it's critical that you pay attention to some symptoms of a bad water pump because the earlier you detect the problem, the cheaper it is to fix it.
11. Corroded exhaust system
Occasionally, you might be dealing with some corrosion around the exhaust system. When these exhaust components are corroded, they can't get loose and might result in rattling while accelerating.
Although the exhaust system is not one of the most common places your car rattles while accelerating, it's not rare to deal with this situation. Therefore, once your mechanic takes a look at the vehicle, he can inspect the different components around the exhaust system and identify the potential culprit.
12. Damaged rocker’s arm
Finally, if you confirm that all previously mentioned components are in good condition, the final step is to look at the rocker’s arm. This rocker arm can go bad for various reasons, and one of the common reasons could be just the normal wear and tear over time of use.
Fixing a bad or damaged rocker arm helps you eliminate the rattling noise every time your car accelerates.
How to fix the problem with rattling noise while accelerating?
As you might notice, there is a long list of potential culprits resulting in your vehicle making a rattling noise every time you accelerate. If you're planning to fix the problem, you need to follow these steps:
1. Identify the potential culprit
Identifying the potential culprit is the most critical step in resolving and getting rid of the rattling noises when accelerating. You can follow certain symptoms that could help you narrow down the list and focus on certain components more than others by learning more about what could happen when any of these components fail.
Many articles help you familiarize yourself with the different symptoms of bad components, including symptoms of a bad water pump, a failing piston ring, etc.
If you are not 100% sure about which problem you're dealing with, you can consult your mechanic and provide him with a detailed description of what you're dealing with. Your mechanic has certain tools and equipment that help him go down the list and understand what is going on in your vehicle.
2. Decide on repair options
Once you identify the potential culprits, the next step is to identify your options for resolving the problem. For example, your mechanic might recommend fixing the component, which means you still have a chance to fix it as is and do not need to install a new component.
However, in other scenarios, you might need to replace the existing component because it's completely damaged. In that case, you also have two options: replace the component with a used component in good condition or purchase a brand-new one.
Keep in mind that there are adventures and adventures for both options. For example, if you decide to go with used components, there's no guarantee that you will not deal with additional problems very soon. On the other hand, if you decide to go with a brand-new component, you have to be careful about potential repair costs.
3. Fix or sell your vehicle
On many occasions, getting rid of the rattling noise when accelerating requires a decent amount of money. In that case, you must evaluate the situation carefully and check whether you need to fix the vehicle or sell it instead.
For example, if you feel that repair costs are getting close to 75% or more of the value of your vehicle, you might need to sell this vehicle rather than waste your time and money. However, if repair costs are low, you can always fix the vehicle to keep it healthy and working again to serve you for the rest of its lifetime.
