How much does it cost to fix a 2012 Mitsubishi Galant 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.

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 2012 Mitsubishi Galant?

To effectively diagnose a cruise control issue in a 2012 Mitsubishi Galant, it's essential to adopt a systematic approach that begins with the simplest checks before progressing to more complex diagnostics. Start by inspecting the cruise control fuse, as a blown or damaged fuse can easily disrupt the system's functionality. Next, examine the cruise control buttons on the steering wheel to ensure they are operational and not stuck, as this can prevent engagement. Following this, check the speed sensors, which are vital for the cruise control system's performance, and use an OBD-II scanner to identify any error codes that may indicate underlying problems. Additionally, verify the brake pedal switch, since a malfunction here can inhibit cruise control activation. Don't overlook the vacuum lines connected to the system; any leaks or damage can significantly impact performance. Finally, assess the cruise control module to confirm it is functioning correctly, as issues here can lead to a complete failure of the system. By methodically working through these steps, you can accurately diagnose and address the cruise control issue in your Mitsubishi Galant.

What are the common problems that could cause the cruise control to stop working in a 2012 Mitsubishi Galant?

When troubleshooting the cruise control system in a 2012 Mitsubishi Galant, it's essential to understand the common problems that may lead to its malfunction. One of the primary issues could be a faulty brake pedal switch, which is crucial for disengaging the cruise control when the brake is applied. If this switch is defective, it may prevent the system from engaging at all. Another potential culprit is a defective speed sensor; this component is responsible for relaying the vehicle's speed to the cruise control system, and if it fails, the system cannot maintain a constant speed. Additionally, a blown fuse related to the cruise control can completely disable the system, making it imperative to check the vehicle's fuse box. Vacuum leaks in the engine can also affect the cruise control's performance, as the system relies on vacuum pressure to function correctly. Lastly, a malfunctioning cruise control module can hinder the system's ability to engage or maintain speed. By identifying these common issues, DIY enthusiasts can better diagnose and potentially resolve the cruise control problems in their Mitsubishi Galant.

How urgent is it to address the malfunctioning cruise control in my 2012 Mitsubishi Galant?

When it comes to a malfunctioning cruise control system in your 2012 Mitsubishi Galant, the urgency to address the issue cannot be overstated. A faulty cruise control can lead to unpredictable vehicle behavior, such as sudden acceleration or deceleration, which significantly increases the risk of accidents on the road. Ignoring these symptoms not only jeopardizes your safety but also that of other drivers and pedestrians. Moreover, delaying repairs can exacerbate the problem, potentially leading to more extensive and costly damage to your vehicle's systems. 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 a safer driving experience and protect your vehicle from further complications.
