The most common reasons a 2016 Kia Sportage cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
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 2016 Kia Sportage 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 2016 Kia Sportage?

To effectively diagnose a cruise control issue in a 2016 Kia Sportage, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the brake light switch, as a malfunction here can prevent the cruise control from engaging. Next, test the cruise control switches on the steering wheel to ensure they are functioning properly; using a multimeter can help confirm their operational status. If these components check out, proceed to inspect the actuator, especially if your vehicle uses a cable-actuated system, by testing it with a battery pack or multimeter. Utilizing an OBD scanner is also crucial, as it can reveal any trouble codes related to the cruise control system or other integrated systems, providing insights into potential malfunctions. Additionally, examine the wiring and connections for any signs of damage or corrosion, as these can disrupt the system's functionality. If your Sportage is equipped with Smart Cruise Control, ensure that the sensors are clean and unobstructed, as dirt or debris can hinder their performance. Lastly, familiarize yourself with the system's limitations, as environmental factors can affect its operation. By following this diagnostic approach, you can efficiently identify and address the cruise control issue, ensuring a smoother driving experience.

What are the common problems that could cause the cruise control to stop working in a 2016 Kia Sportage?

When dealing with cruise control issues in a 2016 Kia Sportage, it's essential to understand the common problems that may arise. One frequent culprit is intermittent electrical issues, which can lead to the cruise control functioning sporadically. This can be particularly challenging to diagnose since the problem may not manifest during a visit to a repair shop. Additionally, faulty steering wheel controls or a malfunctioning brake switch can hinder the cruise control from engaging properly, and while replacing these components might seem like a solution, the underlying issue could be elsewhere. Another area to investigate is the control module, which manages the cruise control system; if this module is faulty or requires a software update, it can lead to malfunctions. Physical components such as the servo, throttle actuator, or the connecting cable may also be damaged, preventing the system from operating correctly. Furthermore, a bad speed sensor can disrupt the cruise control's ability to maintain speed, as it relies on accurate data to function. A simple yet crucial step in troubleshooting is checking for a blown fuse in the cruise control circuit, as this can completely disable the system. Environmental factors, including adverse weather conditions or obstructions on sensors, can also impact performance, particularly for advanced systems like Smart Cruise Control. Lastly, it's important to consider that extreme temperatures or specific road conditions may affect the system's functionality, highlighting the need for a thorough examination of both the vehicle's components and the driving environment. By understanding these common issues, DIYers can better diagnose and address cruise control problems in their Kia Sportage.

How urgent is it to address the malfunctioning cruise control in a 2016 Kia Sportage?

Addressing a malfunctioning cruise control in a 2016 Kia Sportage is crucial due to the potential safety risks and the likelihood of further complications if left unattended. A malfunctioning system can lead to erratic vehicle speed, which poses a significant danger, especially in varying road conditions. This inconsistency can result in unintended acceleration or deceleration, increasing the risk of accidents. Moreover, the inconvenience of a faulty cruise control can distract drivers, making long journeys more tiring and less enjoyable. Ignoring these symptoms can lead to more severe issues, such as problems with the Electronic Control Module (ECM) or other critical components, which may escalate repair costs and complexity. Therefore, it is essential to address any cruise control malfunctions promptly to ensure safe driving conditions and maintain the vehicle's overall functionality. Taking proactive steps, such as consulting a professional mechanic and monitoring the system's performance, can help mitigate risks and prevent further damage.
