How much does it cost to fix a 2018 Dodge Challenger 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 initial diagnostic steps to troubleshoot the non-functioning cruise control in a 2018 Dodge Challenger?

When faced with a non-functioning cruise control in a 2018 Dodge Challenger, start your troubleshooting by checking the cruise control fuse, as a blown fuse can often be the simplest explanation for the issue. Next, ensure that the cruise control settings are correctly configured according to the vehicle's manual, as incorrect settings can prevent the system from engaging. If these initial checks do not resolve the problem, use a diagnostic scanner to look for any error codes that may indicate a deeper issue within the cruise control system. Additionally, inspect the cruise control buttons on the steering wheel for any signs of damage or malfunction, as these controls are crucial for operation. Finally, examine the brake pedal switch, since a malfunction here can cause the cruise control to disengage unexpectedly. By following this structured approach, you can effectively diagnose and potentially resolve the cruise control issue in your Dodge Challenger.

What are the common problems that could cause the cruise control to stop working in a 2018 Dodge Challenger?

When troubleshooting cruise control issues in a 2018 Dodge Challenger, it's essential to understand the common problems that may be at play. One frequent culprit is a faulty brake pedal switch, which is crucial for disengaging the cruise control when the brake is applied; if this switch malfunctions, it can prevent the system from engaging properly. Additionally, speed sensor issues can disrupt the cruise control's functionality, as the system relies on accurate speed readings to maintain the desired speed. Another potential problem could be a blown fuse within the cruise control system, which would require a simple fuse replacement to restore operation. If these components are functioning correctly, the cruise control module itself may be faulty and could need repair or replacement. Lastly, electrical problems, including issues with wiring or other electrical components, can also lead to cruise control failure, often necessitating professional troubleshooting. By systematically checking these areas, you can effectively diagnose and resolve the cruise control problems in your Dodge Challenger.

How urgent is it to address the non-functioning cruise control in a 2018 Dodge Challenger?

When it comes to a non-functioning cruise control in a 2018 Dodge Challenger, the urgency of addressing the issue cannot be overstated. Cruise control is not just a luxury; it plays a crucial role in enhancing driving comfort and safety, particularly during long trips. A malfunctioning system may signal deeper problems within the vehicle's electrical components or sensors, which could lead to more significant issues if left unchecked. Ignoring this symptom can result in increased driver fatigue and inconvenience, especially on extended journeys where maintaining a steady speed is essential. Moreover, a faulty cruise control system may compromise the overall performance and safety of the vehicle, potentially leading to dangerous situations on the road. Therefore, it is imperative for DIY enthusiasts to prioritize the inspection and repair of the cruise control system to ensure the vehicle operates smoothly and safely, preventing further complications down the line.
