Having trouble with your Kia’s exhaust system? It could be your catalytic converter that’s the problem. Although we rarely think of them unless they go wrong, the converter is a vital part of your car that needs to be in top condition. However, there are usually some signs that it’s on the way out. If you spot any of the common problems below, then it’s time to head to your local Kia dealer and get it looked at as soon as possible.

The Check Engine Light Is On

The check engine light has an enigmatic quality about it to most drivers, but it’s an important warning sign that something’s wrong. Some of the many types of issues that can set it off are due to a faulty converter, so make sure you bring your car into us as soon as you notice it’s turned on. Our factory-trained technicians will be able to quickly read the error codes from your engine and find out what’s going on.

Increased Fuel Consumption

If you notice that your car needs to fill up more often than it used to, then it might be time to have a look at your converter. This particular problem can start very gradually and can be hard to spot at first. You’ll often only notice it alongside the more obvious problems on this list, but it’s an important pointer towards your converter being the cause.

Strange Exhaust Smell

While we obviously don’t recommend regularly inhaling your vehicle’s exhaust, a strange odor in your exhaust smoke or from under the hood can be a sure sign there’s a fault with your converter. It might be a sulfurous, rotten egg smell, or very sweet if coolant has leaked in somehow. Either way, you’ll need one of the technicians to take a look.

Failed Emission Test

Your vehicle needs to pass an emissions test as part of its state-mandated roadworthiness inspection. It can be frustrating if it fails, but it’s also a sign that the converter might be at fault, as it’s one of the most important components in keeping your car as clean as possible. Best to get it checked immediately.

Abnormally High Engine Revs

Another common symptom of converter problems is unusually high engine revs, even at low speeds and when you’re not pressing the gas pedal hard. This is caused by a breakdown in the chemical reaction that makes the converter work; this means your engine will be working twice as hard just to get the same result, and you’ll therefore see higher revs.
