How much does it cost to fix a 2011 INFINITI FX35 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.

What are the initial diagnostic steps to troubleshoot the non-functional cruise control in a 2011 INFINITI FX35?

When faced with a non-functional cruise control in your 2011 INFINITI FX35, start by checking the cruise control fuse located in the fuse box; a blown fuse can often be the simplest fix. Next, test the cruise control switch on the steering wheel to ensure it is operational, as a faulty switch can prevent the system from engaging. It's also crucial to examine the brake pedal switch, which should not be stuck or malfunctioning, since the cruise control system is designed to disengage when the brake is pressed. Additionally, inspect the vehicle speed sensor, as it is vital for the cruise control's functionality. Finally, using a diagnostic scanner to check for any error codes can provide deeper insights into potential issues within the system. By systematically following these steps, you can effectively diagnose and address the problem with your cruise control.

What are the common problems that could cause the cruise control to stop working in a 2011 INFINITI FX35?

When troubleshooting cruise control issues in a 2011 INFINITI FX35, it's essential to understand the common problems that may lead to its failure. One frequent culprit is a faulty brake light switch, which can disrupt the system's ability to engage or disengage properly. Additionally, a defective speed sensor can hinder the cruise control's capacity to maintain a consistent speed, while a blown fuse may completely disable the system. It's also important to check for vacuum leaks, as these can affect the operation of vacuum-operated components within the cruise control system. Lastly, a malfunctioning cruise control module can prevent the system from responding to commands or maintaining speed effectively. By identifying these potential issues, DIY enthusiasts can better diagnose and address the problems affecting their vehicle's cruise control functionality.

How urgent is it to repair the non-functioning cruise control in a 2011 INFINITI FX35?

Repairing the non-functioning cruise control in a 2011 INFINITI FX35 is an urgent matter that should not be overlooked. A malfunctioning cruise control system can pose significant safety risks, particularly during long drives or highway travel, where maintaining a steady speed is crucial. The unpredictability of sudden acceleration or deceleration can lead to dangerous driving conditions, increasing the likelihood of accidents. Additionally, the absence of this feature can detract from driving comfort, leading to fatigue as the driver must continuously manage the accelerator pedal over extended periods. Furthermore, a faulty cruise control system may signal deeper issues within the vehicle's mechanics, potentially resulting in more severe damage if left unaddressed. Therefore, prioritizing the repair of the cruise control system is essential not only for ensuring safety and comfort but also for maintaining the overall performance and reliability of your vehicle.
