How much does it cost to fix a 2017 Ford C-Max 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.

What are the steps to diagnose the cruise control issue in a 2017 Ford C-Max?

To effectively diagnose a cruise control issue in your 2017 Ford C-Max, begin with the simplest checks to save time and effort. Start by inspecting the cruise control fuse located in the fuse box; a blown fuse is a common culprit that can easily be replaced. Next, examine the cruise control buttons on the steering wheel to ensure they are functioning correctly, as faulty buttons can disrupt the system's operation. If these initial checks do not resolve the issue, utilize an OBD-II scanner to identify any error codes that may indicate specific problems within the cruise control system. Following this, assess the vehicle's speed sensors, as they are essential for the cruise control to function properly; any malfunction here can lead to significant issues. Additionally, inspect the wiring and connections associated with the cruise control system for signs of damage or corrosion, as these can impede functionality. Finally, if all else fails, test the cruise control module itself to confirm it is working as intended. By systematically following these steps, you can effectively diagnose and address cruise control issues in your vehicle, ensuring a smoother driving experience.

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

When troubleshooting the cruise control system in a 2017 Ford C-Max, it's crucial to identify several common issues that may be causing the malfunction. A faulty speed sensor is often a primary suspect, as it can prevent the system from accurately detecting the vehicle's speed, leading to difficulties in engaging or maintaining cruise control. Additionally, problems with the brake light switch can interfere with the system's operation, since it is designed to deactivate cruise control when the brakes are applied. Another frequent issue is a blown fuse associated with the cruise control system, which can result in a complete shutdown of the functionality. Moreover, a malfunction in the throttle control, particularly a defective throttle position sensor, can significantly affect the cruise control's ability to maintain speed. Lastly, poor electrical connections or wiring issues can also contribute to the failure of the cruise control system. By methodically examining these components, DIY enthusiasts can effectively diagnose and resolve cruise control issues in their Ford C-Max, restoring functionality and enhancing their driving experience.

How urgent is it to address the malfunctioning cruise control in my 2017 Ford C-Max?

When it comes to the malfunctioning cruise control in your 2017 Ford C-Max, the urgency of addressing the issue cannot be overstated. A malfunctioning system can lead to unexpected acceleration or deceleration, creating hazardous driving conditions that could result in accidents. Moreover, such issues may signal deeper problems within your vehicle's electronic systems or sensors, which could compromise other critical functions. Ignoring these symptoms not only jeopardizes your safety but can also lead to decreased fuel efficiency and overall vehicle performance, ultimately resulting in higher maintenance costs. By promptly addressing the cruise control malfunction, you not only enhance your safety on the road but also prevent further damage to your vehicle, ensuring it operates efficiently and reliably for years to come.
