Cruise control
Cruise control is one of the most important comfort and driver assistance systems in cars, as it works to stabilize the speed of the car on highways to relieve the driver from using the gas and brake pedal all the time to make driving more comfortable and relaxed.
Modern cars are equipped with an advanced, adaptive or active cruise control system that works to stabilize the speed in addition to increasing and slowing down the speed according to the movement of the cars in front of it, that is, it automatically presses the gas and brake pedal.
Although cruise control is a safe and reliable system, it may be subject to some malfunctions and issues that lead to it stopping working or not being able to operate it when needed, and there are many cases in which it may malfunction and cause the driver to lose control of the car.

Causes of Cruise Control Failure
As for the causes of cruise control failure, there are many, and we will show them to you below:
Burnout fuse
One of the most common reasons for the failure of the cruise control system is the burning of its fuse, and the function of the fuse is to protect the systems from sudden surges of electricity to prevent them from being damaged, and the burning of the fuse is normal and simple and you can replace it quickly and at a very simple price, but make sure to install a new fuse of the same caliber as the old one so as not to cause other malfunctions.
Electrical issues
Problems with the electrical wires and connections can disrupt the operation of the cruise control system, as they are responsible for receiving commands and transferring power to the system, and the wires can be damaged due to poor maintenance or as the car ages or several other factors.
Damaged ABS sensors
If one of the ABS sensors on all tires is damaged, the cruise control will not work; because this system is closely related to the cruise control system and is an integral part of the braking system and any malfunction in it will affect the cruise control directly.

Speed sensor failure
Your car depends on speed sensors to provide data to the cruise control system, and if these sensors are damaged or do not provide accurate information, the system may not work properly, and the speed sensors can wear out over time or get dirty, and cleaning or replacing them may solve the issue and return the system to work without issues.
Faulty engine control module
The cruise control system relies on the engine control module to process information and control the speed of the car, and if there is a malfunction in this unit, it can lead to various issues with the cruise control system, such as the inability to activate it or maintain a constant speed.
Malfunctioning buttons
The cruise control system contains several buttons to activate, stop, speed up or slow down, and if one of these buttons is damaged, you will not be able to activate it or even turn it off, so always make sure that all buttons work before setting off so that your trip is safe, and be aware that button failure is rare but may occur in some cars, especially old ones.

Leaking vacuum hose
One of the common issues in older cars with vacuum-based speed control system, is the presence of a leak from the vacuum hose, as if there are leaks or cracks in the vacuum hoses, this may lead to a malfunction in the vacuum pressure needed to operate the system, and here comes the importance of regular maintenance to detect any issues or leaks first and foremost before major issues occur - God forbid -.
Failed brake light switch
There are cars equipped with a cruise control system that depends on the brake light in its work, as it is automatically turned off as soon as the brake pedal is pressed due to a command from the brake switch, and if this switch is broken, it gives the system a wrong command and will lead to its work incorrectly and may remain effective even after stepping on the brakes.
