The most common reasons a 2019 Mitsubishi Mirage 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.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2019 Mitsubishi Mirage 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 non-functioning cruise control in a 2019 Mitsubishi Mirage?

To effectively diagnose the non-functioning cruise control in your 2019 Mitsubishi Mirage, begin with the simplest checks to avoid unnecessary complications. Start by inspecting the cruise control fuse located in the fuse box; a blown fuse is an easy fix that can restore functionality. Next, examine the cruise control buttons on the steering wheel for any signs of damage or obstruction, as dirty or stuck buttons can hinder operation. Following this, verify the speed sensor's performance, since a malfunctioning sensor can disrupt the cruise control system. It's also crucial to check the brake pedal switch, as a faulty switch may prevent the cruise control from engaging. Additionally, inspect the throttle cable for any damage or sticking, which could affect the system's operation. If these initial checks do not resolve the issue, utilize a diagnostic scanner to identify any error codes that may provide further insight into the problem. Should you still be unable to diagnose the issue, seeking assistance from a professional mechanic or an authorized Mitsubishi service center is advisable to ensure a thorough resolution. By following this structured approach, you can efficiently troubleshoot and potentially fix the cruise control issue in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2019 Mitsubishi Mirage?

When troubleshooting the cruise control system in a 2019 Mitsubishi Mirage, it's essential to consider several common issues that may be at play. 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. Additionally, problems with the speed sensor can disrupt the cruise control's ability to maintain speed, as it relies on accurate readings to function effectively. Another potential issue is a blown fuse within the cruise control circuit, which can halt the system's operation entirely and is often a straightforward fix. Furthermore, a malfunctioning throttle actuator can impede the cruise control's ability to adjust engine speed, while problems with the Electronic Control Module (ECM) can lead to broader system failures. For those looking to DIY, checking these components can help identify the root cause of cruise control issues, but if the problem persists, consulting a professional mechanic may be necessary for a thorough diagnosis and repair.

How urgent is it to address the malfunctioning cruise control in my 2019 Mitsubishi Mirage?

When it comes to the malfunctioning cruise control in your 2019 Mitsubishi Mirage, the urgency of addressing the issue cannot be overstated. A faulty cruise control system can lead to unexpected acceleration or deceleration, creating a significant safety hazard while driving. This unpredictability not only increases the risk of accidents but can also endanger both you and other road users. Moreover, neglecting to fix the problem promptly may result in further complications within the vehicle's systems, potentially leading to more extensive and costly repairs down the line. Therefore, it is crucial to take immediate action by either inspecting the system yourself or seeking assistance from a qualified mechanic. By prioritizing the repair of your cruise control, you ensure not only your safety but also the longevity and reliability of your vehicle.
