The most common reasons a 2018 Mitsubishi Mirage G4 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 2018 Mitsubishi Mirage G4 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 2018 Mitsubishi Mirage G4?

When diagnosing a cruise control issue in a 2018 Mitsubishi Mirage G4, it's crucial to follow a methodical approach that prioritizes simpler checks before delving into more complex diagnostics. Begin by inspecting the cruise control fuse, as a blown fuse can easily disrupt the system's operation. Next, examine the cruise control buttons on the steering wheel to ensure they are functioning correctly, since faulty buttons can hinder engagement. Utilizing an OBD-II scanner to check for error codes can provide valuable insights into any underlying issues affecting the cruise control system. Additionally, verify the functionality of the vehicle's speed sensors, which are essential for the cruise control's operation; malfunctioning sensors can lead to significant problems. It's also important to inspect the wiring connections related to the cruise control system for any signs of damage or corrosion, as poor connections can result in failures. Finally, test the cruise control module to ensure it is working properly, as a defective module can prevent the system from engaging. If these steps do not resolve the issue, seeking assistance from a professional mechanic experienced with Mitsubishi vehicles is recommended for a thorough diagnosis and repair. By adhering to this structured diagnostic approach, you can effectively identify and resolve cruise control problems in your Mitsubishi Mirage G4.

What are the common problems that could cause the cruise control to stop working in a 2018 Mitsubishi Mirage G4?

When troubleshooting cruise control issues in a 2018 Mitsubishi Mirage G4, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which is designed to disengage the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging. Additionally, issues with the speed sensor can disrupt the cruise control's ability to maintain a steady speed, as the system relies on accurate speed readings to function correctly. Another potential issue is a blown fuse within the cruise control system, which can easily be checked and replaced if necessary. Furthermore, a malfunctioning throttle actuator can hinder the cruise control's performance by failing to regulate engine speed effectively. Problems with the Electronic Control Module (ECM) can also impact the cruise control, as this component is integral to managing various vehicle functions. Lastly, inspect the wiring and connections for any signs of damage or corrosion, as faulty wiring can disrupt communication between the cruise control components. By systematically addressing these common issues, you can effectively diagnose and potentially resolve the cruise control problems in your vehicle.

How urgent is it to address the malfunctioning cruise control in a 2018 Mitsubishi Mirage G4?

Addressing a malfunctioning cruise control in a 2018 Mitsubishi Mirage G4 is crucial for several reasons. First and foremost, a malfunction can lead to unexpected acceleration or deceleration, creating a significant safety hazard on the road. This unpredictability not only endangers the driver but also poses risks to other road users. Additionally, a faulty cruise control system can detract from the overall driving experience, making long trips less enjoyable and convenient. Ignoring these symptoms can also lead to decreased fuel efficiency, as the vehicle may not operate optimally, and could potentially cause damage to other components of the vehicle. By addressing the issue promptly, you can prevent further complications, ensuring that your vehicle remains safe and performs well. Therefore, it is advisable to take action as soon as you notice any problems with the cruise control system to maintain both safety and vehicle integrity.
