  • 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.

How much does it cost to fix a 2013 Toyota Prius C 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 my 2013 Toyota Prius C?

Addressing the malfunctioning cruise control in your 2013 Toyota Prius C should be considered a priority, as neglecting this issue can lead to significant safety risks and inconveniences. A malfunctioning cruise control system not only diminishes the comfort of long drives but can also result in frustration, as you will need to constantly monitor and adjust your speed manually. Furthermore, if the cruise control system is linked to other components such as the brake pedal or throttle body, failing to troubleshoot the problem could lead to broader performance issues that may compromise your vehicle's safety. Therefore, it is crucial to promptly investigate the underlying causes, such as checking for blown fuses or using a scanner to identify any faults. By addressing the cruise control malfunction in a timely manner, you ensure a safer and more enjoyable driving experience, ultimately preventing more serious complications down the road.
