How much does it cost to fix a 2019 Kia Soul EV cruise control isn't working?

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.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

What are the steps to diagnose the cruise control issue in a 2019 Kia Soul EV?

When diagnosing a cruise control issue in a 2019 Kia Soul EV, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before moving on to more complex solutions. Begin by examining the cruise control fuse, as a blown fuse can easily disrupt the system's operation. Next, inspect the cruise control buttons on the steering wheel to ensure they are functioning correctly and are not stuck, as this can prevent engagement. Utilizing an OBD-II scanner to check for error codes can reveal any underlying problems affecting the cruise control system. It's also important to assess the vehicle speed sensor, which is vital for the cruise control's functionality. Additionally, testing the brake pedal switch is necessary, as a faulty switch can prevent the cruise control from activating. Finally, inspect the wiring and connections related to the cruise control system for any signs of damage or corrosion. If these initial steps do not resolve the issue, seeking assistance from a professional mechanic experienced with Kia vehicles is recommended for a comprehensive diagnosis and repair. This methodical approach not only aids in identifying the problem but also ensures that you tackle the most common issues first, potentially saving you time and effort in the troubleshooting process.

What are the common problems that could cause the cruise control to stop working in a 2019 Kia Soul EV?

When troubleshooting cruise control issues in a 2019 Kia Soul EV, it's essential to consider several common problems that could be at play. One of the primary culprits is a faulty speed sensor, which is crucial for the cruise control system to maintain the desired speed accurately. If the speed sensor is malfunctioning, it may not relay the correct information to the cruise control system, leading to erratic behavior. Another potential issue is the brake light switch; if this switch is defective, it can inadvertently signal the cruise control to disengage whenever the brakes are applied, disrupting the system's functionality. Additionally, throttle control problems, such as a malfunctioning throttle position sensor, can hinder the cruise control's ability to maintain speed, as it relies on precise throttle input. Electrical issues, including blown fuses or wiring problems, can also interfere with the cruise control system, making it essential to check the vehicle's electrical components. Lastly, software glitches in the onboard computer can occasionally cause the cruise control to misbehave, so ensuring that the vehicle's software is up to date may resolve the issue. By systematically checking these components, DIY enthusiasts can often identify and address the root cause of cruise control malfunctions in their Kia Soul EV.

How urgent is it to address the malfunctioning cruise control in a 2019 Kia Soul EV?

When dealing with a malfunctioning cruise control in a 2019 Kia Soul EV, it is essential to recognize the urgency of the situation. Ignoring symptoms such as erratic speed control can lead to serious safety risks, including unexpected acceleration or deceleration that may result in accidents. Additionally, a faulty cruise control system can significantly detract from your driving experience, making long trips more stressful and less enjoyable. Beyond immediate safety concerns, neglecting this issue could lead to further complications within the vehicle's systems, potentially resulting in costly repairs that could have been avoided with prompt attention. Therefore, it is highly recommended to consult the vehicle's manual or reach out to a certified Kia service center to assess the situation and take appropriate action. Addressing the malfunction quickly not only ensures your safety but also helps maintain the overall performance and reliability of your Kia Soul EV.
