The most common reasons a 2012 Kia Sedona cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in 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 acceleration and poor engine 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 2012 Kia Sedona 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.

How urgent is it to address the non-functioning cruise control in a 2012 Kia Sedona?

When faced with a non-functioning cruise control in your 2012 Kia Sedona, it's essential to assess the urgency of the situation. While it may not seem like an immediate emergency, neglecting this issue can lead to safety risks, particularly during long drives where maintaining a constant speed is crucial. A malfunctioning cruise control can increase driver fatigue and discomfort, making it harder to focus on the road. Additionally, the underlying causes of the failure—ranging from simple blown fuses to more complex wiring issues—can escalate if not addressed promptly. By investigating the problem early, you can potentially avoid more significant repairs down the line and ensure a safer, more comfortable driving experience. Therefore, while it may not require immediate action, prioritizing the diagnosis and repair of your cruise control system is advisable for both safety and convenience.

Starting difficulty due to defective anti-theft control module

The Kia Sedona is well known for presenting issues to the operator when trying to start the engine. This is especially true for vehicles with the Kia smart key. An issue with the factory vehicle immobilizer control module can cause the vehicle to think it is being stolen. This will immediately disallow the vehicle from starting. Many times, the key is the issue, and vehicles with keyless go or push-to-start technology may function properly if the key is inserted (check owners manual for the location of the port). The newest version of the smart key can be used to press the start button, which will allow the vehicle to register the key when the battery is low. If these quick tips do not allow the vehicle to start, or the vehicle does not use a smart key, diagnostics will need to be performed by a factory authorized Kia service enter.

Software Update Available to Correct Transmission Issues

Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.
