The most common reasons a 2017 Lincoln MKT 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 Lincoln MKT 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 take when the cruise control isn't working on a 2017 Lincoln MKT?

When faced with a malfunctioning cruise control system in a 2017 Lincoln MKT, it's crucial to adopt a systematic diagnostic approach. Begin by checking the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, inspect the cruise control buttons on the steering wheel; if they are unresponsive, they may need repair or replacement. It's also important to verify the speed sensor, which plays a vital role in detecting the vehicle's speed; a faulty sensor can lead to cruise control failures. Additionally, examine the brake pedal switch, since the cruise control system is designed to disengage when the brake is applied, and any issues here could prevent proper operation. Finally, utilizing a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues affecting the cruise control system. By following these steps, you can effectively troubleshoot and potentially resolve the cruise control problem on your Lincoln MKT.

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

When troubleshooting the cruise control system in a 2017 Lincoln MKT, it's essential to understand the common problems that may lead to its failure. One prevalent issue is faulty speed sensors, which can hinder the system's ability to accurately gauge the vehicle's speed, resulting in malfunction. Additionally, a malfunctioning brake light switch can disrupt the cruise control's disengagement process when the brakes are applied, causing it to stop working unexpectedly. Another potential culprit is a blown fuse within the cruise control system, which can prevent it from operating correctly and may require a simple fuse replacement. Furthermore, if the cruise control module itself is faulty, it can impede the system's ability to maintain the desired speed. Lastly, throttle control issues, such as a stuck throttle or problems with the throttle position sensor, can also prevent the cruise control from functioning as intended. Addressing these common issues can help restore the cruise control system's functionality, but for a thorough inspection and repair, consulting a qualified mechanic is recommended.

How urgent is it to address the malfunctioning cruise control in a 2017 Lincoln MKT?

Addressing a malfunctioning cruise control in a 2017 Lincoln MKT is of utmost importance due to the safety risks it poses. A malfunction can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions and increase the likelihood of accidents. Additionally, a faulty cruise control system detracts from the overall driving experience, making long trips less convenient and more stressful. Ignoring these symptoms not only compromises safety but can also lead to further damage within the vehicle's systems, resulting in more extensive and costly repairs down the line. Therefore, it is crucial for vehicle owners to prioritize the diagnosis and repair of cruise control issues to ensure both their safety and the longevity of their vehicle.
