The most common reasons a 2017 Hyundai Santa Fe 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.

How much does it cost to fix a 2017 Hyundai Santa Fe 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.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

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 2017 Hyundai Santa Fe?

To diagnose a cruise control issue in your 2017 Hyundai Santa Fe, begin with the simplest checks to avoid unnecessary complications. Start by inspecting the cruise control fuse; a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent activation. If these initial checks do not reveal the problem, utilize an OBD-II scanner to look for any error codes that may indicate specific malfunctions within the system. Pay close attention to the speed sensors, as they are vital for cruise control operation; ensure they are functioning correctly. Additionally, test the brake pedal switch, since it plays a crucial role in disengaging cruise control when the brakes are applied. Finally, inspect the wiring connections associated with the cruise control system for any signs of damage or loose connections. If you still cannot identify the issue after these steps, it may be time to consult a professional mechanic for further assistance. By following this structured approach, you can effectively troubleshoot and potentially resolve cruise control issues in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2017 Hyundai Santa Fe?

When the cruise control in your 2017 Hyundai Santa Fe ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue. One frequent culprit is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it may prevent the system from engaging. Additionally, issues with the speed sensor can disrupt the cruise control's ability to maintain a steady speed, as the system relies on accurate speed readings to function correctly. Another potential issue is a blown fuse within the cruise control system; checking the fuse box for any damaged fuses and replacing them can often resolve the problem. Furthermore, a malfunction in the throttle control system can hinder the cruise control's performance, as it needs to operate smoothly to maintain the desired speed. Lastly, problems with the Electronic Control Module (ECM), which oversees various vehicle functions including cruise control, can also lead to failures. By systematically checking these components, you can effectively troubleshoot and potentially restore the cruise control functionality in your vehicle.

How urgent is it to address the malfunctioning cruise control in a 2017 Hyundai Santa Fe?

Addressing a malfunctioning cruise control in a 2017 Hyundai Santa Fe is of utmost importance due to the potential safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions and increase the likelihood of accidents. Moreover, neglecting this issue can result in higher fuel consumption, as the vehicle may not maintain optimal speed efficiently. Additionally, the underlying problems that cause the cruise control malfunction could escalate, leading to more significant mechanical or electrical failures that may require costly repairs. Therefore, it is crucial to prioritize the diagnosis and repair of the cruise control system to ensure not only the safety of the driver and passengers but also the overall performance and longevity of the vehicle. Taking prompt action can enhance driving comfort and prevent further complications on the road.
