How much does it cost to fix a 2012 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.

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 2012 Chevrolet Impala?

When diagnosing a cruise control issue in a 2012 Chevrolet Impala, it's essential to adopt a systematic approach that begins with the simplest solutions before progressing to more complex diagnostics. Start by checking the cruise control fuse, as a blown fuse can easily disrupt the system's functionality. Next, inspect the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent proper engagement. Utilizing an OBD-II scanner to scan for error codes is a crucial step, as these codes can pinpoint specific problems within the cruise control system. Following this, examine the speed sensors, which are vital for the cruise control's operation, to confirm they are functioning correctly. Testing the cruise control module is also important, as it must send the right signals for the system to engage. Additionally, inspect all wiring and connections related to the cruise control system for any signs of damage or corrosion that could hinder performance. If these steps do not resolve the issue, consulting a professional mechanic with experience in Chevrolet Impalas may be necessary to ensure a thorough diagnosis and repair. By following this structured diagnostic approach, you can effectively identify and address cruise control issues in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2012 Chevrolet Impala?

When the cruise control in your 2012 Chevrolet Impala ceases to function, it can be frustrating, but understanding the common problems can guide you in diagnosing the issue. One of the primary culprits 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 is a blown fuse; checking the vehicle's electrical system for any blown fuses can quickly reveal if this is the cause of the problem. Additionally, a defective speed sensor can lead to inaccurate speed readings, causing the cruise control to disengage unexpectedly or fail to engage. It's also important to consider vacuum leaks in the engine, as these can disrupt the cruise control's ability to maintain speed. Lastly, a malfunctioning cruise control module may require attention, as it is the brain of the system and can prevent proper operation if it is faulty. By systematically checking these components, you can effectively troubleshoot and potentially resolve the cruise control issues in your Impala.

How urgent is it to address the malfunctioning cruise control in a 2012 Chevrolet Impala?

Addressing a malfunctioning cruise control system in a 2012 Chevrolet Impala is of utmost urgency due to the significant safety risks it poses. A faulty cruise control can lead to unexpected acceleration or deceleration, creating dangerous driving conditions that could result in accidents. Moreover, neglecting this issue may not only compromise your safety but could also lead to more extensive damage to the vehicle's systems, resulting in costly repairs down the line. It is crucial to have the cruise control inspected and repaired by a qualified mechanic as soon as symptoms arise. By taking prompt action, you can ensure the safe operation of your vehicle and avoid the potential hazards associated with a malfunctioning cruise control system.
