How much does it cost to fix a 2017 Acura TLX 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 non-functioning cruise control in a 2017 Acura TLX?

To effectively diagnose the non-functioning cruise control in your 2017 Acura TLX, begin with a methodical approach that emphasizes simplicity and accessibility. Start by checking the cruise control fuse, as a blown fuse can often be the culprit behind system failures. Next, inspect the cruise control buttons on the steering wheel to ensure they are not stuck or damaged, as this can prevent proper engagement. Following this, examine the speed sensors, which are vital for the cruise control's operation; any malfunction here can disrupt functionality. Utilizing an OBD-II scanner to check for error codes can provide valuable insights into underlying issues. Additionally, verify that the brake lights are operational, since a malfunction can inadvertently disengage the cruise control. If these initial checks do not resolve the issue, proceed to test the cruise control module to confirm it is sending the correct signals. Lastly, inspect the wiring and connections for any signs of damage or corrosion that could be affecting the system. If the problem persists after these steps, it may be prudent to consult a professional mechanic for further assistance. By following this structured diagnostic approach, you can efficiently troubleshoot the cruise control system in your Acura TLX.

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

When troubleshooting the cruise control system in a 2017 Acura TLX, it's essential to understand the common problems that may lead to its failure. One of the primary culprits is a faulty brake pedal switch, which can disrupt the engagement and disengagement of the cruise control. Additionally, issues with the speed sensor can result in inaccurate speed readings, causing the system to malfunction. A blown fuse within the cruise control circuit can also prevent the feature from operating correctly. Furthermore, a malfunctioning throttle actuator may hinder the system's ability to maintain the desired speed, while problems with the Electronic Control Module (ECM) can affect various vehicle functions, including cruise control. By identifying and addressing these issues, you can effectively restore the functionality of your cruise control system.

How urgent is it to address the non-functioning cruise control in a 2017 Acura TLX?

Addressing a non-functioning cruise control in a 2017 Acura TLX is crucial for both safety and vehicle performance. When this feature fails, it not only diminishes the convenience of maintaining a steady speed during long drives but may also signal deeper issues within the vehicle's electronic systems or sensors. Ignoring this problem can lead to increased driver fatigue, as the driver must constantly monitor and adjust speed manually, which can be particularly taxing on extended trips. Moreover, a malfunctioning cruise control could indicate potential safety hazards, as it may affect other critical systems in the vehicle. For DIY enthusiasts, it is essential to investigate the root cause of the malfunction promptly, as early detection and repair can prevent more significant damage and costly repairs down the line. Therefore, taking immediate action to diagnose and fix the cruise control issue not only enhances driving comfort but also ensures the overall safety and reliability of the Acura TLX.
