How much does it cost to fix a 2016 Cadillac ATS 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 2016 Cadillac ATS?

When troubleshooting the non-functioning cruise control in a 2016 Cadillac ATS, 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 straightforward issue that can easily disrupt the system. Next, inspect the cruise control buttons on the 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, since faulty sensors can significantly impact cruise control performance. Utilizing a diagnostic scanner to check for error codes can provide valuable insights into any underlying issues. Additionally, ensure that the brake and clutch switches are operating correctly, as malfunctioning switches can inhibit cruise control activation. Finally, examine the wiring and connections associated with the cruise control system for any damage or corrosion, as poor connections can lead to failure. By following these steps, you can effectively diagnose and potentially resolve the cruise control issue in your Cadillac ATS.

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

When dealing with cruise control issues in a 2016 Cadillac ATS, it's essential to understand the common problems that may be at play. One frequent culprit is a failed control module, which can disrupt the system's ability to maintain speed. Additionally, sensor or switch malfunctions, particularly with the brake pedal position sensor, can prevent the cruise control from engaging properly. Throttle actuation problems and throttle body malfunctions are also known to interfere with the system's functionality. It's important to check for blown fuses, as these can easily disable the cruise control. Furthermore, issues with the PRNDL or shifter position switch, along with a defective brake pedal switch, can lead to similar problems. If the brake lights are not functioning correctly due to a bad brake switch, this can also impact the cruise control system. Given the complexity of these potential issues, a thorough inspection by a professional mechanic is recommended to accurately diagnose and resolve the problem, ensuring your cruise control operates smoothly once again.

How urgent is it to address the malfunctioning cruise control in a 2016 Cadillac ATS?

When dealing with a malfunctioning cruise control in a 2016 Cadillac ATS, the urgency of the situation cannot be overstated. This feature, designed to enhance driving comfort and reduce fatigue, can become a significant safety concern if it fails. A malfunctioning system may lead to unexpected acceleration or deceleration, which can jeopardize not only your safety but also that of your passengers and other road users. Ignoring these symptoms can result in more severe issues down the line, potentially leading to costly repairs or even accidents. Therefore, it is crucial to address any cruise control problems as soon as they arise. While DIY troubleshooting may seem tempting, consulting a certified mechanic or a Cadillac specialist is often the best course of action to ensure a thorough diagnosis and effective repair. Prioritizing this issue will help maintain optimal vehicle performance and ensure a safer driving experience.
