The most common reasons a 2015 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.

How much does it cost to fix a 2015 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 2015 Mitsubishi Mirage?

When diagnosing the non-functioning cruise control in a 2015 Mitsubishi Mirage, it's crucial to take a methodical approach that prioritizes simpler fixes before delving into more complex issues. Begin by checking the cruise control fuse located in the fuse box, as a blown fuse is a common culprit that can easily be replaced. Next, inspect the cruise control buttons on the steering wheel to ensure they are functioning properly, since any malfunction here can prevent the system from engaging. After that, verify the speed sensor's operation, as a faulty sensor can significantly disrupt the cruise control functionality. It's also important to examine the brake pedal switch, which is designed to disengage the cruise control when the brakes are applied; ensure it is operational and make any necessary adjustments. To gain further insights, use an OBD-II scanner to check for error codes that may indicate specific problems within the system. Finally, if your vehicle's cruise control relies on vacuum lines, inspect these for any leaks or damage that could affect performance. By systematically addressing these components, you can effectively diagnose and resolve the issues with your cruise control system.

What are the common problems that could cause the cruise control to stop working in a 2015 Mitsubishi Mirage?

When troubleshooting cruise control issues in a 2015 Mitsubishi Mirage, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which can either prevent the cruise control from engaging or cause it to disengage unexpectedly. Additionally, a malfunctioning speed sensor can disrupt the system's ability to maintain a consistent speed, leading to frustration during drives. Another potential issue is a blown fuse, which can completely disable the cruise control system. If the cruise control module itself is defective, it may fail to communicate effectively with other vehicle systems, resulting in malfunction. Lastly, wiring problems, such as damaged or loose connections, can lead to intermittent failures or a total loss of cruise control functionality. By identifying these common issues, DIY enthusiasts can better diagnose and potentially resolve cruise control problems in their Mitsubishi Mirage, although consulting a qualified mechanic is recommended for more complex repairs.

How urgent is it to repair the non-functioning cruise control in a 2015 Mitsubishi Mirage?

When evaluating the urgency of repairing the non-functioning cruise control in your 2015 Mitsubishi Mirage, it's essential to recognize the potential implications of neglecting this issue. While it may not seem like an immediate emergency, the absence of cruise control can significantly impact your driving experience. Safety is paramount; without cruise control, maintaining a consistent speed becomes the driver's responsibility, which can lead to fatigue and increased distraction, especially on long journeys. This not only affects your comfort but also raises safety concerns for you and other road users. Furthermore, addressing this malfunction promptly can help preserve the vehicle's resale value. Prospective buyers often view a malfunctioning feature as a sign of neglect, which could deter them from purchasing your vehicle or lead to lower offers. Therefore, while the repair may not be urgent, it is wise to prioritize fixing the cruise control to enhance your driving safety, comfort, and the overall value of your Mitsubishi Mirage.
