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

When troubleshooting the non-functioning cruise control in a 2017 Ford Mustang, it's important to follow a methodical diagnostic approach that prioritizes simpler checks before moving on to more complex issues. Begin by inspecting the cruise control fuse located in the fuse box, as a blown fuse is a common and straightforward problem to fix. Next, check the cruise control buttons on the steering wheel to ensure they are working properly, since malfunctioning buttons can prevent the system from engaging. It's also essential to verify the functionality of the vehicle's speed sensors, as any issues here can disrupt the cruise control's operation. Utilizing a diagnostic scanner to check for error codes can provide critical insights into specific problems affecting the cruise control system. Additionally, ensure that the brake and clutch switches are functioning correctly, as these components are crucial for activating the cruise control. Lastly, examine the wiring and connections related to the cruise control system for any signs of damage or corrosion, as poor connections can lead to system failure. By systematically addressing these areas, you can effectively identify and resolve the underlying issues with your Mustang's cruise control.

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

When the cruise control in a 2017 Ford Mustang ceases to function, it can be frustrating, but understanding the common problems can help you troubleshoot effectively. One of the primary culprits is a faulty brake pedal switch, which can disrupt the system's ability to engage or disengage as needed. Additionally, a malfunctioning speed sensor may prevent the cruise control from maintaining a consistent speed, leading to erratic performance. It's also essential to check for a blown fuse, as this can completely disable the cruise control system. If these components are functioning correctly, the issue might lie within the cruise control module itself, which could be defective and unable to communicate with the engine. Lastly, inspect the wiring for any damage or loose connections, as these can interfere with the signals necessary for the cruise control to operate. By systematically addressing these potential issues, you can restore the functionality of your Mustang's cruise control and enhance your driving experience.

How urgent is it to address the malfunctioning cruise control in my 2017 Ford Mustang?

Addressing a malfunctioning cruise control system in your 2017 Ford Mustang is crucial for both safety and vehicle performance. When cruise control fails, it can lead to unpredictable acceleration or deceleration, significantly increasing the risk of accidents on the road. This unpredictability not only endangers you and your passengers but also other drivers. Furthermore, ignoring the malfunction can result in decreased fuel efficiency, which translates to higher costs at the pump, and may even lead to more extensive damage to your vehicle's components over time. By promptly diagnosing and fixing the issue, you not only enhance your driving safety but also contribute to the overall longevity and reliability of your Mustang. Therefore, it is essential to prioritize this repair to ensure a safe and efficient driving experience.
