Any new vibration, jerk, or noise emanating from your vehicle, whether accompanied by a warning light on your dashboard or not, can be very disconcerting for drivers and the passengers. Consistent sputtering movements can be particularly alarming as they may indicate a huge risk so it is extremely important to diagnose the problem right away using a motor trade expert.
To help you understand potential causes of vehicle juddering, below is a list that may help you get to the bottom of the problem as quickly as possible.
Malfunctioning spark plugs
Worn-out or dirty spark plugs that need a good clean may cause your engine to misfire, judder, or jerk when you put your foot down on the accelerator. Luckily, if this is the problem ailing your engine, this is a fairly quick as you can purchase the right spark plugs for your vehicle and head over to your local garage mechanic to help with replacement.
A faulty ignition coil
An ignition coil is a component that magnifies the battery’s power during start-up to create enough electrical power for the engine to come to life. Failure or improper operation of one ignition coil causes one of your engine cylinders to seize, which may cause the engine to vibrate irregularly and cause a juddering noise.
Ignition coil trouble is often exhibited by symptoms such as problems starting your vehicle and poor fuel economy — so if the juddering is accompanied by these symptoms, be sure to have your ignition coils checked out as soon as possible.
A broken lambda sensor
A lambda sensor is a crucial element found in the exhaust system of most modern vehicles that ensures the correct fuel-air mixture for environmentally friendly and efficient combustion. In the event that this lambda sensor is malfunctioning, an inaccurate fuel-air ratio might be sent to your car’s computer, which in turn alters the fuel mixture to either a lean or rich mix, this causes engine vibrations that could result in damage.

Faulty CV joints
Constant Velocity (CV) joints are notorious for causing juddering movements in your vehicle. Worn-out CV joints can prevent the engine from transmitting enough power to the wheels, which might cause the car to pull from one side and start making loud clicking sounds when taking corners. Worn-out or broken CV joints should never be ignored as it could lead to your vehicle breaking down.
Faulty braking system
If you notice that juddering consistently happens when you apply the brakes, these are a few things to check out:
• Worn brake pads that have become ineffective
• Brake discs fitted incorrectly causing misalignment
• An overheating brake disc that has led to its distortion
• Uneven wear on brake discs causing one side to be thicker than the other.
All the above issues can result in a juddering noise when braking and might compromise both your insurance policy and your safety on the road if you don’t get them checked out. Juddering noises while braking should be addressed immediately by your local motor trade mechanic. New and used vehicles are designed to run smoothly, juddering sounds are a sign that something might not be running right and should be addressed as soon as possible.
