How much does it cost to fix a 2017 Ford Explorer 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 initial diagnostic steps to troubleshoot the non-functional cruise control in a 2017 Ford Explorer?

When faced with a non-functional cruise control in your 2017 Ford Explorer, start by checking the cruise control fuse, as a blown fuse can often be the simplest fix. Next, verify that the cruise control settings are correctly configured according to your vehicle's manual, ensuring that the system is activated properly. If these initial checks do not resolve the issue, use a diagnostic scanner to look for any error codes that may indicate a deeper problem within the cruise control system. Additionally, inspect the cruise control buttons on the steering wheel for any signs of damage or malfunction, as these can prevent the system from engaging. Finally, examine the brake pedal switch, since a stuck or faulty switch can inadvertently disengage the cruise control when the brake is pressed. By systematically following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Ford Explorer.

What are the common problems that could cause the cruise control to stop working in a 2017 Ford Explorer?

When the cruise control in a 2017 Ford Explorer ceases to function, several common issues may be at play. One of the primary culprits is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging. Additionally, problems 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 circuit; inspecting 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 adjust the throttle to maintain the set speed. The Electronic Control Module (ECM) also plays a crucial role in managing the cruise control system, and any issues with the ECM can lead to operational failures. Lastly, vacuum leaks in the engine can interfere with the cruise control's functionality, so checking for and repairing any leaks is essential. By systematically addressing these common problems, DIYers can effectively troubleshoot and potentially restore the cruise control system in their Ford Explorer.

How urgent is it to address the malfunctioning cruise control in a 2017 Ford Explorer?

When it comes to a malfunctioning cruise control system in a 2017 Ford Explorer, the urgency of addressing the issue cannot be overstated. A malfunctioning system can lead to unexpected acceleration or deceleration, creating a significant safety hazard for both the driver and other road users. Promptly addressing this issue is crucial to prevent accidents that could arise from erratic vehicle behavior. Additionally, neglecting the problem may not only compromise safety but could also result in further damage to the vehicle's components, leading to more extensive and costly repairs down the line. Therefore, it is highly advisable to have the cruise control system inspected and repaired by a qualified mechanic or authorized service center as soon as symptoms arise. Taking swift action ensures the vehicle remains safe and reliable, maintaining optimal performance standards on the road.
