How much does it cost to fix a 2017 Land Rover Discovery Sport 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 steps should I take to diagnose the non-functioning cruise control in my 2017 Land Rover Discovery Sport?

To effectively diagnose the non-functioning cruise control in your 2017 Land Rover Discovery Sport, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by inspecting the cruise control fuse located in the fuse box, as a blown fuse is a common and easily fixable issue that can halt the system's operation. Next, examine the cruise control buttons on your steering wheel for any signs of damage or sticking, as these can prevent the system from engaging. Following this, verify the functionality of the speed sensors on the wheels, since faulty sensors can disrupt the cruise control's ability to maintain speed. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues within the cruise control system. Additionally, ensure that the brake and clutch switches are functioning correctly, as malfunctioning switches can disable cruise control. Finally, inspect the wiring and connections associated with the cruise control system for any damage or corrosion, as these can lead to operational failures. By following this structured diagnostic approach, you can efficiently identify and address the root cause of your cruise control issues.

What are the common problems that could cause the cruise control to stop working in a 2017 Land Rover Discovery Sport?

When troubleshooting the cruise control system in a 2017 Land Rover Discovery Sport, 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, problems with the brake light switch can cause the cruise control to disengage unexpectedly, even when the brakes are not applied, disrupting its functionality. Throttle control malfunctions, particularly with the throttle position sensor, can also impede the system's capacity to maintain a consistent speed. Furthermore, electrical issues such as wiring faults, blown fuses, or problems with the cruise control module can interfere with the necessary signals for operation. Lastly, vacuum leaks in the engine can prevent the cruise control from sustaining a steady speed. By identifying and addressing these issues, you can effectively restore the cruise control functionality in your vehicle.

How urgent is it to address the malfunctioning cruise control in a 2017 Land Rover Discovery Sport?

Addressing a malfunctioning cruise control in a 2017 Land Rover Discovery Sport is of utmost importance due to the potential safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions for both the driver and others on the road. Additionally, a malfunctioning cruise control can detract from the overall driving experience, making long journeys less convenient and more stressful. Ignoring these symptoms not only compromises safety but can also lead to more significant issues within the vehicle's systems, resulting in costly repairs down the line. Therefore, it is crucial to prioritize the diagnosis and repair of cruise control problems promptly to ensure safe and enjoyable driving.
