The most common reasons a 2019 Chevrolet Impala 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.

How much does it cost to fix a 2019 Chevrolet Impala 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 cruise control issue in my 2019 Chevrolet Impala?

To effectively diagnose the cruise control issue in your 2019 Chevrolet Impala, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the cruise control fuse located in the fuse box; a blown fuse can often be the root of the problem. Next, examine the cruise control buttons on your steering wheel to ensure they are not stuck or malfunctioning, as this can prevent the system from engaging. Following this, check the speed sensors, which are vital for cruise control operation; ensure they are clean and functioning properly. If these initial checks do not reveal the issue, utilize an OBD-II scanner to look for any error codes that may indicate specific problems within the cruise control system. Additionally, inspect the vacuum lines for any leaks or damage, as these can also disrupt the system's functionality. Finally, if all else fails, consider testing or replacing the cruise control module, as it may be faulty. By following this diagnostic approach, you can efficiently identify and address the cruise control issue in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2019 Chevrolet Impala?

When the cruise control in your 2019 Chevrolet Impala ceases to function, it can be frustrating, but understanding the common issues can help you diagnose the problem. One frequent culprit is a faulty brake pedal switch, which can disrupt the system's ability to engage or disengage properly. Additionally, a defective speed sensor may provide inaccurate readings, leading to cruise control malfunctions. It's also worth checking for a blown fuse, as this can completely disable the cruise control feature. If these components are functioning correctly, consider inspecting the cruise control module itself, as a malfunction here can prevent the system from operating as intended. Lastly, electrical problems, such as wiring issues, can also interfere with the cruise control system. By systematically checking these areas, you can identify the root cause of the issue and take the necessary steps to restore your vehicle's cruise control functionality.

How urgent is it to address the malfunctioning cruise control in a 2019 Chevrolet Impala?

Addressing a malfunctioning cruise control in a 2019 Chevrolet Impala is of utmost urgency due to the significant safety risks it poses. A faulty cruise control system can lead to unexpected acceleration or deceleration, creating hazardous driving conditions, particularly on highways where maintaining a consistent speed is crucial. Moreover, such issues may signal deeper electronic system or sensor malfunctions, which could compromise the vehicle's overall performance and safety. Ignoring these symptoms not only risks immediate safety but can also lead to decreased fuel efficiency and potential damage to other vehicle components over time. By promptly diagnosing and repairing the cruise control system, you can prevent further damage and potentially save on costly repairs in the future. Therefore, it is essential to prioritize this issue to ensure safe and efficient driving.
