The most common reasons a 2024 Kia Soul has a check engine light are an emissions system component, a sensor, or a catalytic converter.
  • Emissions System: A faulty emissions system component, such as an oxygen sensor or EGR valve, can lead to increased emissions and trigger the check engine light.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2024 Kia Soul has a check engine light?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

A faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

When the Check Engine Light comes on, you may experience engine performance issues such as poor acceleration, rough idling, or an engine that won't start. In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time. Similar lights may say "Check Engine Soon", "Malfunction Indicator Light" or just "Check". In rare case the engine can overheat.

What are the initial steps to diagnose the check engine light on a 2024 Kia Soul?

When faced with a check engine light on your 2024 Kia Soul, start by assessing the dashboard for any additional warning lights, as these can offer valuable insights into the underlying issue. Next, inspect the gas cap; a loose or damaged cap is a common culprit that can easily trigger the light. Following this, conduct a visual inspection of the vehicle for any apparent damage, such as leaks or frayed wires, which may indicate a more serious problem. If these initial checks do not resolve the issue, utilizing an OBD-II diagnostic scanner is a crucial next step. This tool will help you retrieve error codes from the vehicle's computer, providing specific information about the malfunction. Finally, don’t forget to consult your owner’s manual, as it contains manufacturer-specific guidance that can aid in troubleshooting. By systematically following these steps, you can effectively diagnose the check engine light and take informed actions towards resolving the issue.

What are the common problems that could cause the check engine light to illuminate in a 2024 Kia Soul?

When the check engine light comes on in a 2024 Kia Soul, it can indicate several common issues that are often manageable for DIY enthusiasts. One of the simplest problems to check is a loose gas cap, which can easily be tightened or replaced if damaged. More complex issues may involve the oxygen sensor, which affects fuel efficiency and can be tested with an OBD-II scanner. If the catalytic converter is malfunctioning, it may require professional attention, but symptoms like decreased power can be indicators. Spark plug wear is another frequent culprit; inspecting and replacing spark plugs can restore engine performance. Additionally, the mass airflow sensor and ignition coil are critical components that can lead to misfires if faulty, and both can be tested for functionality. Lastly, issues with the EGR valve can also trigger the check engine light, and while some repairs may be straightforward, others might necessitate a mechanic's expertise. Addressing these problems promptly not only helps in maintaining vehicle performance but also prevents further damage, making it essential for DIYers to stay informed about these common issues.

How urgent is it to address the check engine light in a 2024 Kia Soul?

When the check engine light illuminates in your 2024 Kia Soul, it is crucial to recognize the urgency of the situation. This warning light is not merely a nuisance; it signals potential issues within your vehicle's engine or emissions system that could range from minor to severe. Ignoring this alert can lead to decreased fuel efficiency and may escalate into more significant engine damage, which can be costly to repair. Moreover, some underlying problems could pose safety risks while driving, making it imperative to act swiftly. By having your vehicle inspected by a qualified mechanic as soon as the light comes on, you can diagnose the issue early and take corrective measures, ultimately saving yourself from more extensive repairs and ensuring your safety on the road. Addressing the check engine light promptly is not just about maintaining performance; it is about safeguarding your investment and your well-being.
