Have you ever experienced a sudden, engine bump, or abrupt, abnormal noticeable movement while accelerating or decelerating your vehicle while driving at a constant speed? These sudden noticeable bumps in your vehicle are known as car jerks. These jerks make driving experience irritating, uneven, and uncomfortable. Car jerk is a common problem for both electric vehicles and internal combustion engine vehicles. Today in this article we will discuss the reason behind the car jerks and the solution for car jerks when accelerating at low speed.

Car Jerks

What is Car Jerks?

The sudden abnormal or jolt in the vehicle engine while driving is called a car jerk. These abnormal jolts make the driving experience very irritating and bumpy. One can experience car jerking problems in ICE-powered vehicles as well as electric vehicles. There are multiple reasons of car jerking. So to understand this problem better, we are mentioning the common reasons that can cause jerks in your vehicle.

Car Jerks reasons

Common Reasons of Jerks in Traditional Fuel-Powered Vehicles

  • Engine Misfire– A misfiring engine can cause jerking due to issues with spark plugs, ignition coils, or the fuel delivery system.
  • Transmission Issues– Multiple problems in transmission like slipping, hesitation, or gear shifting issues, can lead to car jerks.
  • Fuel System Problems– The issues with the fuel injectors, fuel filters, or fuel pumps can disturb the fuel delivery system of a vehicle. This disturbance in fuel delivery system can cause the engine to jerk.
  • Ignition System Faults– Problems with components like the ignition module or ignition timing can also result in uneven engine performance and jerking.
  • Sensor Malfunctions– Faults in-vehicle sensors like mass airflow sensor (MAF), throttle position sensor (TPS), or oxygen sensors, can negatively impact the operation of the engine and lead to jerking.
  • Faulty Engine Mounts– Worn or damaged engine mounts leads the vehicle engine to move excessively, causing jerking sensations.
  • Vacuum Leaks
  • Braking System Issues
  • Wheel and Tire Problems
  • Faults in Electronic Control Module (ECM) or Engine Control Unit (ECU)

Common Reasons of Jerks in Electric Vehicles

  • Software UpdatesElectric vehicles regularly receive software updates for continuous improvement in performance and driving quality. We advise you to check whether there are any available updates for your Electric vehicle that are causing jerking. So to overcome this jerking issue you need to install the updates as recommended by the manufacturer.
  • Drive Mode Settings– Different electric vehicles offer different drive modes that can affect acceleration behavior. Therefore you need to check, if the driving modes of your EV are the reason behind the vehicle jerking issues.
  • Regenerative Braking– Sometimes regenerative braking systems in electric vehicles can also cause jerking. Therefore you can check if your electric vehicle is offering adjustments to regenerative braking settings and try different configurations.
  • Battery Health– A degraded or faulty battery will impact the performance of an electric vehicle and cause jerking.
  • Torque Vectoring Systems– Issue with the torque vectoring system of electric vehicles can also leads to jerking
  • Motor or Inverter Issues
  • Wheel and Tire Issues
  • Faulty Sensors

 Solutions for Internal Combustion Engine Powered Car Jerks

  • Check Faulty Spark Plugs– Worn-out or faulty spark plugs can lead to misfires and jerking, so to overcome this issue you need to change the faulty spark plugs
  • Cleaning or Replacing of the Mass Airflow Sensor (MAF) – A dirty, choked or malfunctioning MAF sensor can affect air-fuel mixture causing jerking. If needed, you should clean or replace the Mass Airflow Sensor to overcome the jerking issue.
  • Inspection of Throttle Position Sensor (TPS) – A fault in the throttle position sensor can cause engine jerking. You can inspect the TPS for any possible issue and replace it if necessary.
  • Checking Fuel System– Clogged or choked fuel injectors or a dirty fuel filter can negatively affect the fuel delivery system leading to jerking. You can clean or replace the fuel injectors or fuel filters to overcome this jerking issue.
  • Check for Vacuum Leaks
  • Evaluate the Transmission Fluid
  • Inspect the Throttle Body
  • Diagnosing Sensors of vehicle
  • Review Engine Control Module (ECM)
  • Check Power train Control Module (PCM) Issues
  • Check for Wheel and Tire Issues

Solutions for Jerking In Electric Vehicles
  • Software Updates– You should check the software of your electric vehicles for any updates. Make sure all the software of your electric vehicle is up to date.
  • Drive Mode Settings– Check for any possible fault in the drive mode setting. If necessary, experiment with different drive settings of your EV. It can affect the acceleration behavior.
  • Battery Health Check– Check the health of the EV battery because a degraded or faulty battery can negatively affect the performance of your EV. Replace it if necessary
  • Motor and Inverter Inspection– You should inspect the electric motor and inverter for any possible malfunction.
  • Regenerative Braking Settings– If your EV allows it you can adjust the regenerative braking settings. A change in regenerative braking behavior can positively affect the jerking issues and overall driving experience.
  • Inspect Wheel and Tire Conditions for any uneven wear and tear.
  • Sensor Health Check- Check for any faults in sensors.
  • Check the Torque Vectoring Systems for any possible malfunction.
  • Check the vehicle braking system for any possible issue
