If your car is making a knocking noise, it's important to get it checked out as soon as possible. This could be a sign of engine trouble and if left unchecked, it could lead to more serious issues.
If you're hearing a knocking noise coming from your engine, it could be caused by a few different things. It could be something as simple as loose change or debris in the engine bay, or it could be something more serious like an issue with the connecting rods or bearings.
If you hear a knocking noise when driving, pull over and turn off the engine immediately. Then, check under the hood to see if there's anything obvious that could be causing the noise. If you don't see anything, have your car towed to a nearby mechanical workshop so they can take a closer look.
In most cases, a knocking noise coming from your car's engine is nothing to worry about and can be easily fixed. However, if left unchecked it could lead to more serious problems down the line so it's always best to get it checked out as soon as possible.
