The most common reasons a 2016 Buick Enclave cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2016 Buick Enclave 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 initial diagnostic steps to troubleshoot the non-functioning cruise control in a 2016 Buick Enclave?

When troubleshooting the non-functioning cruise control in a 2016 Buick Enclave, start with the simplest checks to avoid unnecessary complications. Begin by inspecting the fuses associated with the cruise control system, as a blown fuse can easily disrupt functionality. Next, examine the brake pedal and throttle body; any issues here can directly impact cruise control operation. It's also crucial to verify the integrity of the wiring harnesses and connectors, looking for any loose or damaged connections that could lead to electrical failures. If these initial checks do not reveal the problem, proceed to inspect the control module, sensors, and switches for signs of malfunction. Utilizing a diagnostic scanner can provide deeper insights into any underlying issues within the cruise control system. Lastly, ensure that the brake lights are functioning correctly, as faulty brake lights can prevent the cruise control from engaging. By systematically following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Buick Enclave.

What are the common problems that could cause the cruise control to stop working in a 2016 Buick Enclave?

When dealing with cruise control issues in a 2016 Buick Enclave, it's essential to understand the common problems that could be at play. One frequent culprit is a malfunctioning control module, sensor, or switch, which can disrupt the system's operation. Additionally, throttle actuation problems may prevent the cruise control from engaging properly. It's also important to check for blown fuses, as these can easily interrupt the electrical flow necessary for the cruise control to function. Another area to investigate is the brake pedal position sensor; if this sensor is faulty, it may incorrectly signal that the brakes are engaged, thereby disabling the cruise control. Throttle body malfunctions and issues with the PRNDL or shifter position switch can further complicate matters. Lastly, if the check engine light is illuminated, it could indicate an underlying engine issue that affects the cruise control system. By systematically examining these components, DIYers can effectively troubleshoot and potentially resolve the cruise control problems in their Buick Enclave.

How urgent is it to address the malfunctioning cruise control in a 2016 Buick Enclave?

Addressing a malfunctioning cruise control system in a 2016 Buick Enclave is of utmost importance due to the potential safety risks it poses. A malfunction can lead to unexpected acceleration or deceleration, creating hazardous driving conditions, especially on highways where maintaining a steady speed is crucial. Additionally, a faulty cruise control can significantly detract from the driving experience, leading to discomfort and increased fatigue for the driver, which can further compromise safety. Moreover, ignoring these symptoms may result in further damage to the vehicle's components, leading to more extensive and costly repairs down the line. Therefore, it is essential to prioritize the repair of the cruise control system not only to ensure the safety of all road users but also to maintain the vehicle's performance and longevity.
