How much does it cost to fix a 2017 Jeep Wrangler 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 Jeep Wrangler?

When troubleshooting the non-functioning cruise control in a 2017 Jeep Wrangler, it's essential to adopt a systematic diagnostic approach. Begin by checking the cruise control fuse located in the fuse box, as a blown fuse is a common and easily fixable issue. Next, inspect the cruise control buttons on the steering wheel to ensure they are operational, as malfunctioning buttons can prevent the system from engaging. Following this, verify the functionality of the vehicle's speed sensors, since faulty sensors can disrupt the cruise control's performance. Utilizing a diagnostic scanner to check for any error codes related to the cruise control system can provide valuable insights into specific malfunctions. Additionally, ensure that the brake lights are functioning correctly, as a defective brake light switch can inhibit cruise control engagement. Lastly, if your Jeep Wrangler employs a vacuum-operated cruise control system, inspect the vacuum lines for any leaks or damage, as these can significantly impact functionality. By methodically following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Jeep Wrangler. If problems persist, seeking assistance from a professional mechanic may be necessary for more complex repairs.

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

When troubleshooting the cruise control system in a 2017 Jeep Wrangler, it's essential to understand the common problems that may lead to its failure. One of the primary culprits is a faulty brake light switch, which can prevent the cruise control from engaging since the system is designed to deactivate when the brake pedal is pressed. Additionally, issues with the speed sensor can disrupt the vehicle's ability to maintain a constant speed, leading to cruise control malfunctions. A blown fuse within the cruise control system is another straightforward issue that can easily be checked and replaced to restore functionality. Furthermore, a defective cruise control module may require replacement if it fails to operate correctly. Lastly, problems with the throttle control, particularly a malfunctioning throttle position sensor, can hinder the cruise control's performance. By systematically addressing these potential issues, you can effectively diagnose and resolve the cruise control problems in your Jeep Wrangler.

How urgent is it to address the malfunctioning cruise control in a 2017 Jeep Wrangler?

Addressing a malfunctioning cruise control in a 2017 Jeep Wrangler is of utmost importance due to the safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create dangerous driving conditions not only for the driver but also for other road users. Additionally, a malfunctioning cruise control diminishes the convenience and enjoyment of driving, making long trips more stressful. Ignoring these symptoms can lead to further complications, including increased wear and tear on the vehicle's components, which may result in more extensive and costly repairs down the line. Therefore, it is crucial to prioritize the repair of the cruise control system to ensure a safe and reliable driving experience.
