The most common reasons a 2013 Toyota Prius cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in 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 acceleration and poor engine response.

How much does it cost to fix a 2013 Toyota Prius 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.

How urgent is it to address the malfunctioning cruise control in a 2013 Toyota Prius?

When it comes to addressing a malfunctioning cruise control in your 2013 Toyota Prius, understanding the urgency of the situation is crucial. While it may not seem like an immediate emergency, neglecting this issue can lead to more significant problems down the line. The cruise control system is integral to your vehicle's communication and functionality, allowing for a more comfortable driving experience by maintaining a constant speed. Common causes of malfunction include a failed control module, faulty sensors, or issues with the throttle actuation, which can compromise not only the convenience of the feature but also your safety on the road. If you notice symptoms such as unresponsive controls or erratic speed adjustments, it’s advisable to investigate further. Addressing these issues promptly can prevent potential safety risks and avoid costly repairs in the future. Therefore, while you may not need to rush to a mechanic, scheduling a timely check-up will ensure that your cruise control system operates smoothly, enhancing both your driving comfort and safety.

Mitsubishi Diamante cruise control malfunction after drive line obstruction removal

Some Mitsubishi Diamante owners report experiencing cruise control malfunctions after removing a drive line obstruction, often linked to issues with the control module, sensor, or switch. These problems may stem from failed components that prevent the cruise control system from engaging or holding speed, despite power being available to the dash and fuse. Additionally, throttle actuation issues, such as a faulty throttle position sensor, can lead to the engine's computer overcompensating with fuel, which may result in black exhaust from the tailpipe. Owners are advised to thoroughly troubleshoot the cruise control system and inspect key components like the control module, sensor, and throttle to identify any damage or malfunction caused during the obstruction removal process.
