How much does it cost to fix a 2016 GMC Sierra 1500 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 steps should I take to diagnose the non-functioning cruise control in my 2016 GMC Sierra 1500?

To effectively diagnose the non-functioning cruise control in your 2016 GMC Sierra 1500, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the fuse associated with the cruise control system, as a blown fuse is a common culprit for this issue. Next, examine the brake pedal switch, which is crucial for deactivating cruise control when the brake is pressed; ensure it is operating correctly. Following this, check the cruise control switch itself for any signs of damage or malfunction. It’s also important to look for any loose or damaged connections within the cruise control system, as these can disrupt functionality. If these initial checks do not resolve the issue, proceed to test the cruise control module, as it may be the source of the problem. Should you find yourself unable to pinpoint the issue after these steps, consulting a certified mechanic is advisable to ensure a thorough and accurate diagnosis. By following this structured diagnostic approach, you can efficiently identify and address the problem with your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2016 GMC Sierra 1500?

When the cruise control in your 2016 GMC Sierra 1500 ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue. One frequent culprit is a faulty brake light switch, which is crucial for the cruise control system as it disengages the cruise when the brakes are applied. If this switch is malfunctioning, it may prevent the cruise control from engaging altogether. Another potential issue lies with the speed sensor; if this component is not accurately relaying speed information, the cruise control may fail to maintain a constant speed. Additionally, a blown fuse in the cruise control circuit can disrupt its operation, making it essential to check and replace any damaged fuses. Problems with the throttle actuator control system can also affect cruise control functionality, as this system regulates the engine's throttle position. Lastly, malfunctions in the electronic control module (ECM) can lead to broader issues, including cruise control failure, since the ECM oversees various vehicle functions. By systematically checking these components, you can effectively troubleshoot and potentially resolve the cruise control issues in your GMC Sierra 1500.

How urgent is it to address the malfunctioning cruise control in my 2016 GMC Sierra 1500?

When it comes to the malfunctioning cruise control in your 2016 GMC Sierra 1500, understanding the urgency of the situation is crucial for both your safety and driving comfort. While it may not seem like an immediate emergency, neglecting this issue can lead to more significant problems down the line. A malfunctioning cruise control system can disrupt your driving experience, especially during long trips where maintaining a steady speed is essential. Common causes of cruise control failure include issues with control modules, sensors, and throttle actuation, which can all impact the vehicle's performance. For DIY enthusiasts, troubleshooting can begin with simple checks, such as inspecting fuses, evaluating the brake pedal and throttle body, and using a diagnostic scanner to pinpoint the problem. Addressing these issues promptly not only enhances your driving convenience but also prevents potential safety risks associated with unexpected acceleration or deceleration. Therefore, while it may not be an urgent fix, taking the time to resolve cruise control malfunctions will ensure a safer and more enjoyable driving experience.
