The most common reasons a 2014 Acura RLX 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 2014 Acura RLX 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 are the steps to diagnose the cruise control issue in a 2014 Acura RLX?

To effectively diagnose a cruise control issue in your 2014 Acura RLX, begin with the simplest solutions. Start by checking the cruise control fuse to ensure it is intact, as a blown fuse can easily disrupt the system. Next, inspect the cruise control buttons on the steering wheel for any signs of damage or sticking, as these can prevent proper operation. If these initial checks do not reveal the problem, use an OBD-II scanner to look for error codes that may indicate specific issues within the cruise control system. Following this, examine the speed sensors, which are vital for the cruise control's functionality, and ensure they are operating correctly. Additionally, test the brake pedal switch, as a malfunction here can deactivate the cruise control. Finally, inspect the wiring connections for any loose or damaged wires that could be causing the issue. If you have gone through these steps and the problem persists, it may be time to consult a professional mechanic for a more thorough diagnosis. This methodical approach not only saves time but also helps you understand the underlying issues with your vehicle's cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2014 Acura RLX?

When dealing with cruise control issues in a 2014 Acura RLX, several common problems may be at play. One of the first things to check is the fuse associated with the cruise control system; a blown fuse can easily disrupt its functionality. Additionally, the cruise control switch itself may be faulty, preventing the system from engaging or disengaging as intended. Another critical component to consider is the speed sensor, which plays a vital role in maintaining a constant speed; any malfunction here can lead to erratic behavior of the cruise control. Furthermore, the brake light switch is essential for the system's operation, as it is designed to disengage cruise control when the brakes are applied; a faulty switch can cause the cruise control to fail unexpectedly. Lastly, issues with the throttle actuator can hinder the system's ability to adjust speed accurately. By understanding these potential problems, DIYers can better diagnose and address cruise control issues in their Acura RLX, ensuring a smoother driving experience.

How urgent is it to address the malfunctioning cruise control in a 2014 Acura RLX?

Addressing a malfunctioning cruise control system in a 2014 Acura RLX is of utmost importance due to the immediate safety risks it poses. A faulty system can lead to unexpected acceleration or deceleration, which can create hazardous driving conditions not only for the driver but also for other road users. Additionally, a malfunctioning cruise control can significantly detract from the overall driving experience, causing discomfort and frustration during long trips. Ignoring these symptoms can lead to more severe issues within the vehicle's systems, potentially resulting in expensive repairs down the line. Therefore, it is crucial for owners to prioritize the diagnosis and repair of cruise control problems to ensure both safety and the longevity of their vehicle.
