How much does it cost to fix a 2017 Lincoln MKC 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 2017 Lincoln MKC?

When faced with a non-functioning cruise control in a 2017 Lincoln MKC, it's essential to adopt a systematic diagnostic approach. Start by checking the cruise control fuse, as a blown fuse can often be the simplest explanation for the malfunction. Next, ensure that the cruise control settings are correctly configured according to the vehicle's manual, as incorrect settings can prevent the system from engaging. If these initial checks do not resolve the issue, use a diagnostic scanner to look for any error codes that may indicate specific problems within the cruise control system. Additionally, inspect the cruise control buttons on the steering wheel for any signs of damage or sticking, as these can hinder functionality. It's also crucial to examine the brake pedal switch, since a faulty switch can interrupt the cruise control operation. Finally, verify the vehicle speed sensor's functionality, as an issue here can directly impact the cruise control's ability to maintain speed. By following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Lincoln MKC.

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

When dealing with cruise control issues in a 2017 Lincoln MKC, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty speed sensor, which can disrupt the system's ability to accurately gauge the vehicle's speed, preventing the cruise control from engaging or maintaining speed. Additionally, a blown fuse can interrupt the electrical flow necessary for the cruise control system to function properly. Another potential issue lies with the brake light switch; if this switch is malfunctioning, it can signal the cruise control to disengage unexpectedly. Furthermore, problems with the throttle actuator, which regulates engine speed, can hinder the cruise control's performance, making it difficult to maintain a set speed. Lastly, a defective cruise control module may also be responsible for the system's failure to operate correctly. If you encounter any of these issues, it is advisable to consult a qualified mechanic who can accurately diagnose and resolve the problem, ensuring your cruise control system operates smoothly once again.

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

When it comes to a malfunctioning cruise control system in your 2017 Lincoln MKC, the urgency of addressing the issue cannot be overstated. A faulty cruise control can lead to unexpected acceleration or deceleration, creating a significant safety hazard for both you and other road users. Beyond safety concerns, neglecting this problem can adversely affect your driving experience, making it inconvenient to use this feature as intended. Additionally, a malfunctioning system may contribute to increased fuel consumption, which not only impacts your wallet but can also lead to further wear and tear on your vehicle's components. By addressing the issue promptly, you can prevent more extensive damage to the cruise control system, ultimately saving you from costly repairs down the line. Therefore, it is crucial to have the malfunction diagnosed and repaired by a qualified mechanic as soon as possible to ensure your safety and maintain the performance of your Lincoln MKC.
