You can experience some car troubles while you’re driving. You can be surprised by a simple squeaking sound or a jerk when accelerating or decelerating. When you own a car, you frequently need maintenance, which is required. Additionally, if you acquire a used car in the UAE, make sure it is thoroughly inspected to avoid any problems in the future brought on by worn-out or clogged parts.

A motorist anticipates smooth braking or acceleration. But if a car jerks when braking or speeding up from a stop, there can be a problem with the car. Let’s go over all the causes of jerking when your car accelerates, brakes, slows down, or stops. If you’re looking to buy or sell a car, platforms like CarSwitch can assist you in finding the right vehicle that meets your needs and preferences.

Car Jerking While Driving: The Causes

There could be a number of issues if you experience jerking, stuttering, or surging when accelerating or braking. There are several causes of car jerks, from faulty brakes to blocked fuel filters.

Here, we’ve categorized the causes of a car jerk into the following groups:

  • Car jerks when applying brakes
  • Car jerks when maintaining speed

Reason Why My Car Jerks Forward When I Brake?

The braking system itself can be the main reason why your automobile shakes when applying the brakes. The potential causes of a car shaking when applying the brakes are as follows:

  • Improper brake disc installation
  • Poor brake pads and discs
  • ABS failure,
  • worn-out brake rotors,
  • Worn-out steering or wheel axle bearings,

Improper Brake Disc Installation

When brakes are used, a car may jolt because of improper brake disc installation or bent discs that increase friction.

There is a risk that the mechanic put the brake discs incorrectly if you recently had them replaced. Nevertheless, improper installation can lead to friction and harm brake discs and pads. In order to prevent the automobile from jerking when the brake pedal is depressed, damaged brake discs must be repaired.

Worn Brake Discs and Pads

Over time, worn-out brake discs and pads can cause an automobile to jerk while using the brakes.

When you push the brake pedal, a car may jerk as a result of bad braking discs and pads. Additionally, when the brake pads are worn out, you can hear squeaking noises. As a result, you must get the old brake pads or discs replaced.

Faulty Brakes

A jerking sensation may be brought on by braking rotor corrosion. Brake rotors are vulnerable to extreme wear and tear after a given amount of time because of overheating and quick cooling. That stated, when the brake pads press against the rotors and cause a car to jolt, the deformity of the brake rotors is clearly visible.

Actuation Failure in Abs

If ABS fail, a car may slide or jerk.

When using brakes, an anti-lock braking system (ABS) prevents the wheels from locking up and aids in gaining traction. However, under normal circumstances, if the ABS malfunctions, it may result in abrupt braking.

Worn-Out Wheel or Steering Bearings

A jerk can occur when a wheel stops because of worn-out wheel bearings.

Numerous bushings, bearings, and connectors used in cars serve to reduce vibrations. However, if the steering or wheel bearings are worn-out, your car may jolt forward when braking.

Why Does My Car Jerk When I Slow Down or Maintain Speed?

You might feel the car jerking even if you haven’t used the brakes while maintaining speed. There are a number of fixes for this jerky acceleration and slow car speed. Let’s go over the following issues that can cause strange sensations in your car while you accelerate or decelerate:

Transmission Difficulties

  • Defective fuel injectors
  • Clogged ignition coil or spark plug
  • A transmission issues
  • Issue with the fuel pump or filter
  • Mass Airflow (MAF) sensor malfunction
  • Catalytic converter obstruction
  • A defective transmission will result in jerks when shifting gears.

When shifting gears, you can experience a shock when the vehicle’s speed accelerates and decelerates. Possible causes of this vehicle jerk include a broken gearbox control module. However, both manual and automatic transmissions are susceptible to this.

A Poor MAF Sensor

Accelerating or decelerating will be problematic if the MAF sensor is broken.

The proper air-fuel ratio is controlled by the mass airflow sensor (MAF). You must investigate the issue and replace the MAF sensor if it is broken because it could be causing drag as you accelerate or decelerate.

You may scan this issue using automobile diagnostic tools because it is tied to the computers in cars. In addition, a faulty MAF sensor will probably cause the check engine light to come on.

Ignition Coil or Spark Plug That Is Worn Out

A spark plug’s primary job is to ignite the mixture of air and fuel. The ignition of the fuel may be delayed if your engine has blocked spark plugs or a malfunctioning ignition coil. A check engine light will also come on if your spark plugs are worn out.

Energy System Issues

Car jerks could result from a malfunctioning fuel filter or pump because it won’t be supplying enough fuel. Additionally, this issue may result in the engine cranking but the car not starting. So, bring your car to a qualified mechanic who can identify the issue and fix it.

Defective Fuel Injectors

Due to a lean air-fuel ratio, corroded fuel injectors can make a car jolt when accelerating.

Your car won’t squirt the appropriate amount of fuel when its fuel injectors are rusted or worn out. Despite this, the automobile won’t jerk when accelerating from a stop because it won’t have the necessary air-fuel ratio.

Problem with The Catalytic Converter

The rich air-fuel mixture running through your catalytic converter could cause it to become blocked. The car will jerk when the driver depresses the accelerator due to a clogged catalytic converter. Your issue may be solved by buying a new catalytic converter.

Unclean Air Filter

Lean air-fuel mixture results from a filthy air filter blocking appropriate air passage.

An air filter’s primary job is to remove airborne debris. The air won’t pass through your car air filter effectively if there are residues on it. If so, you’ll need to change the air filter to stop the car from jerking or the engine from misfiring.
