Hyundai Sonata Jerks When Slowing Down

Nobody likes to ride in a car that is jerking as you hit the brakes or as you slow down. Obviously, this is not a normal situation, and it makes you wonder what exactly has gone wrong with your car.

But if your vehicle is an automatic transmission one, then it is definitely abnormal for your car to react this way.

It is more than a sound created by your vehicle when it jerks. Instead, it is a feeling, which means the vibrations are going on quite rapidly. It is almost as though your vehicle is gasping for air.

So when your car jerks as you slow down, there is an imbalance going on between the fuel and air that enter the engine. Certain components may be causing the imbalance, which is why you will need to troubleshoot.

Other possible reasons behind the jerking action is an issue with the tires or brakes. The fuel filter may also be blocked, so that is another thing worth considering.

You need to keep in mind that your car has filters that screen out impurities. These also prevent debris from getting into the engine. But when the filters are clogged with dirt, then they are unable to do their job more efficiently.

Another possible issue is with the throttle position sensor. If it is malfunctioning, the car will also jerk. After all, the sensor impacts the throttle’s position. So, if there is a failure, then the car tends to jerk.

And lastly, a misaligned or damaged tire can cause the car to pull, jolt, and jerk. You may need to inspect your tires and make sure there is no nail, glass, or metal that’s causing them to be out of alignment.

Car Jerking – Why Does This Happen And Is It Bad?

With the interior components of a car becoming more and more complex, there are many possible reasons why a car jolts as you slow down.

It is usually very common in the early morning, especially with the engine still cold. This is why you want to warm it up first, so the engine will ensure a smoother performance of your vehicle.

Next, there are cases when bad spark plugs cause the jerking. These components deliver to the ignition an electrical current that then ignites the fuel and air, sending power to your engine. A simple spark plug replacement should easily solve the problem.

Or, perhaps there is moisture building up in your vehicle’s distributor cap. Hence, the car jerks and jolts. This is a key component of the ignition system, which is why you want to make sure there is no moisture. Otherwise, the coils are unable to send electricity required to your spark plugs.

And of course, without the required voltage, the spark plugs are unable to work well, causing the car to jerk as you slow down.

If the jerking happens when you hit the brakes, perhaps the computer senses your vehicle’s slowing down. The transmission then goes into a downshift, which causes the jerking motion.

The brake lines may also have some air in them, or the brake pads need replacement. Sometimes, it could also be damaged rotors that cause the problem. Hence, you need to get these changed to help the brakes to function better.
