How much does it cost to fix a 2020 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 cruise control issue in a 2020 Mitsubishi Mirage?

To effectively diagnose a cruise control issue in a 2020 Mitsubishi Mirage, it's essential to adopt a systematic approach that begins with simpler checks before progressing to more complex diagnostics. Start by inspecting the cruise control fuse to ensure it is intact, as a blown fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel for any signs of damage or malfunction, as these controls are crucial for operation. Following this, check the speed sensors, which are vital for the cruise control system to function correctly; any faults here can lead to issues. Utilizing an OBD-II scanner can provide valuable insights by revealing any error codes that may indicate specific problems within the system. If these preliminary checks do not resolve the issue, proceed to test the cruise control module to ensure it is sending the appropriate signals. Additionally, inspect the wiring and connections for any loose or damaged components that could be affecting performance. If the problem persists after these steps, it may be time to consult a professional mechanic who specializes in Mitsubishi vehicles for a thorough diagnosis and repair. This methodical approach not only helps in identifying the issue but also saves time and resources by addressing the most likely causes first.

What are the common problems that could cause the cruise control to stop working in a 2020 Mitsubishi Mirage?

When the cruise control in your 2020 Mitsubishi Mirage ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. 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 may prevent the system from engaging at all. Additionally, issues with the speed sensor can disrupt the cruise control's operation, as the system relies on accurate speed data to maintain the desired speed. Another potential issue could be a blown fuse, which can cut power to the cruise control system entirely. If these components check out, consider the cruise control module itself; a malfunction here may require repair or replacement. Lastly, don't overlook the possibility of electrical problems, such as damaged wiring or a faulty control switch, which can also hinder the cruise control's functionality. By systematically checking these areas, you can identify and resolve the issue, restoring your vehicle's cruise control system.

How urgent is the repair of the non-functioning cruise control in a 2020 Mitsubishi Mirage?

When evaluating the urgency of repairing the non-functioning cruise control in your 2020 Mitsubishi Mirage, it's essential to consider several key factors. First and foremost, safety is paramount; a malfunctioning cruise control system can compromise your ability to maintain a consistent speed, particularly on long drives or highways, which may lead to dangerous driving conditions. Additionally, the convenience factor cannot be overlooked; without cruise control, long trips can become more tiring and uncomfortable, potentially detracting from your overall driving experience. Furthermore, if you plan to sell or trade in your vehicle in the future, having all features, including cruise control, in working order can significantly enhance its resale value. Therefore, while the urgency of the repair may vary based on personal driving habits and preferences, addressing the issue promptly is advisable to ensure safety, comfort, and the vehicle's long-term value. Consulting with a qualified mechanic can provide clarity on the specific problem and the best course of action to take.
