How much does it cost to fix a 2017 Acura ILX 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 steps to diagnose the cruise control issue in a 2017 Acura ILX?

When diagnosing a cruise control issue in a 2017 Acura ILX, it's essential to adopt a systematic approach that begins with the simplest checks before progressing to more complex diagnostics. Start by inspecting the cruise control fuse, as a blown fuse can often be the root of the problem. Next, examine the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent the system from engaging. Utilizing an OBD-II scanner to check for error codes can provide valuable insights into any underlying issues. Additionally, inspect the speed sensors, as they are critical for the cruise control system's functionality. It's also important to verify that the brake lights are operational, since a malfunctioning brake light switch can disrupt cruise control. If these initial checks do not reveal the issue, proceed to test the cruise control module to ensure it is functioning correctly. Finally, inspect the wiring and connections for any signs of damage or corrosion that could be affecting the system. By following this structured diagnostic approach, you can effectively identify and address the cruise control issue in your Acura ILX.

What are the common problems that could cause the cruise control to stop working in a 2017 Acura ILX?

When troubleshooting the cruise control system in a 2017 Acura ILX, it's essential to consider several common problems that could be at play. One of the first areas to check is the cruise control switch, as a malfunction here can prevent the system from engaging or disengaging properly. Additionally, inspect the fuses related to the cruise control; a blown fuse can disrupt the entire system's functionality. The speed sensor is another critical component, as it helps maintain a constant speed; any issues with this sensor can lead to erratic behavior of the cruise control. Furthermore, the brake light switch should be examined, as a faulty switch can cause the cruise control to disengage unexpectedly when the brakes are applied. Lastly, the throttle actuator, which regulates engine speed, may also be a culprit if it is not functioning correctly. By systematically checking these components, you can identify the root cause of the cruise control issue and potentially resolve it without needing to consult a mechanic.

How urgent is it to address the malfunctioning cruise control in a 2017 Acura ILX?

Addressing a malfunctioning cruise control in a 2017 Acura ILX is of utmost importance due to the significant safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can result in dangerous driving situations and increase the likelihood of accidents. Moreover, timely intervention not only enhances driving comfort but also ensures that the vehicle operates efficiently, preventing unnecessary fuel consumption. Ignoring these symptoms can lead to more severe issues, potentially damaging other components of the vehicle and resulting in costly repairs down the line. Therefore, it is crucial to prioritize the diagnosis and repair of cruise control problems to maintain both safety and vehicle performance.
