The most common reasons a 2016 Ford Flex 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 2016 Ford Flex 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-functioning cruise control in a 2016 Ford Flex?

When troubleshooting the non-functioning cruise control in your 2016 Ford Flex, start with the simplest checks to avoid unnecessary complications. Begin by inspecting the fuses associated with the cruise control system, as a blown fuse can often be the culprit behind its failure. Next, examine the brake pedal and throttle body; any issues here can directly affect the cruise control's operation. To further diagnose the problem, have a friend sit in the driver's seat and engage the cruise control buttons while you observe for any signs of activity or response. This hands-on approach allows you to pinpoint the issue more effectively, setting the stage for more advanced troubleshooting if necessary. By following these initial steps, you can efficiently identify the root cause of your cruise control problems and determine the next steps for repair.

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

When dealing with cruise control issues in a 2016 Ford Flex, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which can inadvertently signal the cruise control system to disengage, preventing it from functioning correctly. Additionally, speed sensor issues can arise, as this component is crucial for maintaining a constant speed; if it fails or provides inaccurate readings, the cruise control may not operate as intended. Another potential problem is a blown fuse, which can disrupt the electrical flow to the cruise control system, necessitating a simple fuse check and replacement. Throttle control malfunctions, often linked to a faulty throttle position sensor, can also hinder the cruise control's ability to maintain speed. Furthermore, electrical problems such as loose connections or damaged wiring can lead to system failures, making it vital to inspect these components. Lastly, software glitches within the vehicle's onboard computer may cause the cruise control to stop working, and updating or resetting the system could resolve these issues. By identifying and addressing these common problems, drivers can effectively troubleshoot and restore their cruise control functionality.

How urgent is it to address the malfunctioning cruise control in a 2016 Ford Flex?

Addressing a malfunctioning cruise control in a 2016 Ford Flex is crucial for both safety and driving comfort. When cruise control fails, it can significantly affect your driving experience, especially during long trips where maintaining a steady speed is essential. Simple issues, such as a blown fuse or a faulty brake light switch, can often be resolved quickly and affordably, making it worthwhile to investigate these possibilities before seeking professional help. However, if the problem is more complex, delaying repairs could lead to further complications, potentially escalating into more serious mechanical failures that could compromise vehicle safety. Therefore, it is advisable to prioritize the diagnosis and repair of cruise control issues promptly. By doing so, you not only enhance your driving experience but also prevent minor problems from developing into costly repairs, ensuring that your Ford Flex remains reliable and safe on the road.
