How much does it cost to fix a 2018 Chevrolet Colorado 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.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

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 2018 Chevrolet Colorado?

To effectively diagnose a cruise control issue in your 2018 Chevrolet Colorado, begin with the simplest checks to avoid unnecessary complications. Start by inspecting the cruise control fuse; a blown fuse is a common culprit that can easily disrupt functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are responsive and not stuck, as faulty buttons can prevent the system from engaging. If these initial checks do not reveal the problem, utilize a diagnostic scanner to identify any error codes from the vehicle's onboard computer, which can provide insights into specific malfunctions. Following this, assess the speed sensors, as they are integral to the cruise control system's operation; any faults 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 performance. Finally, if all else fails, test the cruise control module itself to confirm it is functioning correctly. By systematically following these steps, you can effectively diagnose and address cruise control issues in your Chevrolet Colorado, ensuring a smoother driving experience.

What are the common problems that could cause the cruise control to stop working in a 2018 Chevrolet Colorado?

When troubleshooting cruise control issues in a 2018 Chevrolet Colorado, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging properly. Additionally, speed sensor issues can arise, as an inaccurate reading of the vehicle's speed can disrupt the cruise control's functionality. Another potential problem is a blown fuse within the cruise control system, which can easily be checked and replaced to restore operation. Furthermore, the cruise control module itself may be defective, necessitating a replacement to ensure proper engagement and speed maintenance. Lastly, electrical problems, including wiring issues or a malfunctioning control switch, can significantly impact the cruise control's performance. By systematically addressing these common issues, you can effectively troubleshoot and resolve cruise control problems in your Chevrolet Colorado, ensuring a smoother driving experience.

How urgent is it to address the malfunctioning cruise control in a 2018 Chevrolet Colorado?

Addressing a malfunctioning cruise control in a 2018 Chevrolet Colorado is of utmost importance due to the safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions. For DIY enthusiasts, understanding the urgency of this issue is crucial; neglecting it not only compromises your safety but can also lead to increased fuel consumption and potential damage to the engine or related components. Promptly diagnosing and repairing the cruise control system ensures that your vehicle operates efficiently and safely, preventing further complications down the line. If you're not confident in your ability to troubleshoot the issue, seeking professional assistance is advisable to avoid any risks associated with a malfunctioning system.
