Any unusual sound coming from your car will most likely alarm you whether it comes with a dashboard warning light or not, a constant and alarming sound coming from your car can be scary, you should address the issue as soon as possible before it causes more damage or costs you more than it would have before!

This article is all about car juddering, it is not normal for your car to judder constantly, it should be running smoothly through all of the actions, such as gear changes, acceleration and breaking should all seem seamless. If your car is juddering and you would like to make it stop (which you should) here are the different possible causes of the juddering...

Spark plugs

Spark plugs can be the primary reason why your car is juddering, if your spark plugs are used and worn out or need a clean, that can cause the engine to misfire which will make your car judder or jerk when accelerating. Spark plugs are not an expensive fix if you think that your spark plugs are faulty, change them for new ones!

Ignition coil

Ignition coils in your engine carry electricity from your battery to your engine which makes it fire, if one of your ignition coils is not working correctly it is not supplying enough power to your engine, causing it to judder or jerk. This could very easily become an expensive fix, if you don't take notice of it and get it checked out in time you will have to pay out on a serious fix!

Broken lambda sensor

Most modern cars have at least one lambda sensor in their exhaust system, the lambda sensor makes, sure enough, oxygen is supplied to your diesel/petrol. If the lambda sensor is broken it will give the car computer an incorrect reading after which the fuel mixture is changed and the proportion of air in it becomes too much which will cause your car to judder and eventually if left long enough without being fixed will cause severe engine damage.

Faulty constant velocity joints

constant velocity joints also referred to as CV joints, could also be a reason for your car juddering if they are faulty they can stop the drive-train emitting enough power, which would make your car pull to one side or cause juddering when you are turning. CV joints should not be ignored, if they are left without taking action and are broken they could cause your car just to stop in the middle of the road and cause very expensive damage to your drive-train.

Brakes

If your car only judders or makes the juddering sounds when you apply the brakes, there could be multiple issues with your brakes that is causing it,

- An incorrectly fitted disc brake causing misalignment.

- A brake disc overheating, and becoming distort as a result.

- A disc brake is thicker on one side due to uneven wear.

Disc brakes are one of the car components that should never go by ignored because you are putting your and other peoples live at stake, you should always make sure your brakes are working well and as they should.

Acceleration

If your vehicle judders or makes concerning sounds when you accelerate there could be multiple different issues causing it to do so, for example as previously mentioned it could be your spark plugs, if they are old or worn out you should get them changed so that they do not cause more damage to your engine. Another possible reason could be your catalytic converter, if your catalytic converter is clogged it will cause your engine to struggle to receive air. There are many different catalytic converters available for petrol and diesel vehicles. We at Autozone offer a huge selection of catalytic converter cleaners.
