How much does it cost to fix a 2016 Hyundai Elantra 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 steps should I take to diagnose the non-functioning cruise control in my 2016 Hyundai Elantra?

When diagnosing the non-functioning cruise control in your 2016 Hyundai Elantra, it's crucial to take a methodical approach that prioritizes simpler checks before delving into more complex issues. Begin by examining the cruise control switch to ensure it is operational, as a malfunctioning switch is a common cause of cruise control failure. Next, observe the dashboard indicators when you attempt to activate the cruise control; if no lights illuminate, this could indicate a blown fuse. Consult your vehicle's manual to locate the fuse box and inspect the cruise control fuse visually or with a multimeter. If the fuse appears intact, turn your attention to the throttle position sensor, as a failure in this component can disrupt engine performance and impact cruise control functionality. Additionally, check the brake pedal and throttle body for any obstructions or malfunctions, as these parts are essential for the cruise control system to operate correctly. If you notice any warning messages related to the Smart Cruise Control, it may be wise to seek assistance from an authorized HYUNDAI dealer for a comprehensive evaluation. By following this structured diagnostic process, you can effectively pinpoint and resolve the issues affecting your cruise control system.

What common issues cause cruise control failure in a 2016 Hyundai Elantra?

When dealing with cruise control failure in a 2016 Hyundai Elantra, it's essential to understand the common problems that may be at play. One of the primary culprits is a malfunctioning control module, which can disrupt the entire cruise control system. Additionally, issues with the throttle actuation can prevent the system from maintaining speed, while faulty wiring or switches may lead to intermittent functionality. Another frequent issue is a defective cruise control module itself, which can fail to communicate properly with the vehicle's computer. Lastly, a malfunctioning throttle position sensor can not only affect cruise control but also cause the engine to run rich, leading to black exhaust emissions. By identifying these common problems, DIYers can effectively diagnose and potentially resolve cruise control issues in their Hyundai Elantra.

How urgent is it to address the malfunctioning cruise control in a 2016 Hyundai Elantra?

Addressing a malfunctioning cruise control in a 2016 Hyundai Elantra is of utmost urgency due to the significant safety risks it poses. A malfunctioning system can lead to steering lock-up, which may result in a loss of vehicle control, endangering both the driver and others on the road. Additionally, issues with the cruise control can affect the vehicle's overall performance, including erratic acceleration and inaccurate speedometer readings, which can compromise the driving experience. Ignoring these symptoms can lead to more severe problems, such as engine overcompensation due to a faulty throttle position sensor, potentially resulting in costly repairs and environmental concerns like excessive exhaust emissions. Furthermore, since the cruise control system relies on electrical components, a blown fuse can render it inoperable, making it essential to check and replace any faulty fuses promptly. Therefore, it is crucial to address any cruise control malfunctions immediately to ensure safety, maintain vehicle performance, and prevent further damage.
