Why does my Kia Optima make vibrations when accelerating?

So let’s begin our content page with the roots of this kind of issue on your car. You should already know that an engine, especially if it is old or if it has been driven quite a lot, can naturally vibrate without being a issue behind it. Large diesel engines, especially those with a lot of torque, can cause this form of discomfort, both at idle and when accelerating.

I feel vibrations on my Kia Optima only when accelerating

Let’s take the most interesting circumstance for us in this content page. The fact that you experience trembling on your Kia Optima during your acceleration periods, in this circumstance you will have to verify the state of some parts because a good number of elements can be at the source of these vibrations and whether or not you are unlucky a combination of several of them may also be possible, here is the list of auto parts that can be concerned.

  • Turbo: If the turbo of your Kia Optima is defective, it may cause vibrations that you will feel when you accelerate at the moment it is turned on.
  • The turbo pressure sensor: This sensor will manage the pressure exerted in the turbo of your car, if it fails it may affect the behavior of your turbo and create vibrations that you may experience at the time of acceleration of your Kia Optima.

    • .

  • If the turbo is punctured or damaged, the result will be similar, the power supply of your turbo will be disrupted and its behavior too. Remember to visually check their condition.

We will now concentrate on the case where you experience vibrations on your Kia Optima when you are accelerating but also when you are idling. If you only experience vibrations when you are idling on your Kia Optima, please read our content page focused on this issue to fix your problem. If, on the other hand, you detect that your Kia Optima vibrates when accelerating but also when it is stopped, here is the list of things to check:

  • EGR valve: In reality this valve which handles the return of exhaust gases for pollution standards can become dirty and bother the evacuation of exhaust gases which can cause Kia Optima vibrates when accelerating but also when stopped.
  • Injectors: Your injectors that control the fuel/air mixture flow may be dirty or damaged, which will bring out the wrong amount of mixture and thus prevent your engine block from working effectively, it is even possible that one or more of your cylinders are not running effectively.
  • Fuel Filter: Like the injectors, if the filter is clogged it will not let the fuel pass effectively and therefore bother the performance of your Kia Optima, up to the point of generating vibrations during acceleration.

Here are the main triggers of a Kia Optima that vibrates at acceleration

What can I do to stop the vibration when I accelerate on my Kia Optima? What can I do?

To finish , in this last part, we will tell you the solutions available to you to get over these tremors on your car when you accelerate. Here is the best attitude to adopt depending on the part that is involved:

  • Turbo: If your turbo starts all these vibrations when you accelerate your Kia Optima, it will be good for you to control all the auto parts linked to it because changing a complete turbo is a big budget and in most cases the issue does not come directly from the turbo. So make sure you check out your turbo pressure sensor, your flowmeter, the EGR valve and the hoses of your turbo. Otherwise take your Kia Optima to your workshop.
  • EGR valve: The EGR valve has the advantage that it is often easy to access and easy to disassemble/clean. You can always check out it and clean it, for this see our content page on cleaning the EGR valve of an Kia Optima.
  • Injectors: Injectors are very sensitive auto parts and a few impurities may be enough to bother their performance. Use a fuel additive to simply clean the injectors, if this is not enough you will have to go to a professional.
  • Fuel Filter: If it is the fuel filter, just replace it. A fuel filter doesn’t clean itself, so if it is clogged you will simply have to replace it with a new one.

Now you have all the info you need to find the cause of the vibrations at acceleration on your Kia Optima. If you don’t feel able to do certain operations don’t hesitate to go to your motor mechanic.
