How much does it cost to fix a 2017 Lincoln Navigator 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.

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 Lincoln Navigator?

When diagnosing a cruise control issue in a 2017 Lincoln Navigator, it's crucial to follow a structured diagnostic approach that prioritizes simpler checks before moving on to more complex assessments. Begin by inspecting the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are working correctly, since malfunctioning buttons can prevent proper engagement. Utilizing an OBD-II scanner to check for error codes is also essential, as these codes can provide insights into specific problems within the cruise control system. Additionally, verify the functionality of the vehicle's speed sensors, which are integral to the cruise control's operation. It's important to inspect the wiring connections related to the cruise control system for any signs of damage or corrosion, as poor connections can significantly affect performance. Finally, test the cruise control module to ensure it is functioning as intended. If these steps do not resolve the issue, seeking assistance from a professional mechanic with expertise in Lincoln vehicles is advisable for a thorough diagnosis and repair. This systematic approach not only aids in efficiently identifying the problem but also ensures that the most common issues are addressed first, ultimately saving time and effort in the troubleshooting process.

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

When the cruise control in your 2017 Lincoln Navigator ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. One of the primary culprits is often faulty speed sensors, which are crucial for the system to accurately gauge and maintain your vehicle's speed. Additionally, a malfunctioning brake light switch can disrupt the cruise control, as it is designed to disengage the system when the brakes are applied. Another potential issue could be a blown fuse, which can prevent the cruise control from operating altogether. If these components check out, consider examining the cruise control module itself, as a fault here can hinder the system's ability to engage or maintain speed. Lastly, don't overlook the possibility of vacuum leaks in the engine, as these can significantly impact the cruise control's performance. By systematically checking these areas, you can identify and resolve the issues affecting your cruise control system, allowing you to enjoy a smoother driving experience.

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

When dealing with a malfunctioning cruise control in a 2017 Lincoln Navigator, the urgency of the situation cannot be overstated. A malfunctioning system can lead to unexpected acceleration or deceleration, which poses significant safety risks while driving. This unpredictability can result in accidents or loss of vehicle control, making it crucial to address the issue immediately. Additionally, the comfort of your driving experience is compromised, particularly during long trips where cruise control is typically utilized for ease. Ignoring these symptoms may not only diminish your driving comfort but could also lead to further complications within the vehicle's systems, resulting in more extensive and costly repairs. Therefore, it is essential to prioritize the repair of your cruise control system to ensure both your safety and the longevity of your vehicle.
