How much does it cost to fix a 2017 Acura MDX 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 steps should I take to diagnose the non-functioning cruise control in my 2017 Acura MDX?

To effectively diagnose the non-functioning cruise control in your 2017 Acura MDX, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by inspecting the cruise control fuse in the fuse box; a blown fuse is an easy fix that can often resolve the issue. Next, examine the cruise control buttons on your steering wheel for any signs of damage or sticking, as these can hinder functionality. Following this, verify the speed sensor's operation, since a malfunctioning sensor can disrupt the cruise control system. It's also essential to check the brake pedal switch, which must be functioning correctly to allow cruise control to engage. If these initial checks do not reveal the problem, utilize an OBD-II scanner to identify any error codes that may indicate specific issues within the system. Additionally, if your vehicle employs a vacuum-operated cruise control system, inspect the vacuum lines for leaks or damage. If you still cannot determine the cause of the malfunction, seeking assistance from a qualified mechanic or dealership is advisable for a professional diagnosis. By following this structured diagnostic approach, you can efficiently troubleshoot the cruise control issue in your Acura MDX.

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

When troubleshooting the cruise control system in a 2017 Acura MDX, 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 is crucial for disengaging the cruise control when the brake is applied. If this switch malfunctions, it can prevent the system from engaging properly. Additionally, issues with the speed sensor can disrupt the vehicle's ability to maintain a constant speed, leading to cruise control failure. Another potential issue is a blown fuse within the cruise control system, which can completely disable its functionality. Furthermore, problems with the throttle control system can affect how the engine speed is regulated, impacting the cruise control's performance. Lastly, if the Electronic Control Module (ECM) encounters issues, it can interfere with various functions, including cruise control. Understanding these common problems can help you diagnose the issue more effectively, but for a definitive solution, consulting a professional mechanic is recommended.

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

Addressing a malfunctioning cruise control in a 2017 Acura MDX is of utmost importance due to the safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create dangerous driving conditions for both the driver and other road users. Additionally, a malfunctioning cruise control diminishes the convenience and enjoyment of driving, as it disrupts the intended functionality of the vehicle. Ignoring these symptoms not only compromises safety but can also lead to further wear and tear on the vehicle's components, resulting in more extensive and costly repairs down the line. Therefore, it is crucial to prioritize the diagnosis and repair of cruise control issues promptly to ensure a safe and reliable driving experience.
