Hyundai, founded in 1967 in Seoul, South Korea, has grown to become one of the largest car manufacturers in the world. Hyundai Palisade is one of the popular and competitive electric vehicles. However, despite its many top notch features and perks, there are still some common problems that are related to the electric car, such as the speedometer not working.
The speedometer is used to calculate the speed of the vehicle by interacting with the transmission and driveshaft. Using your car’s computer, it is able to translate the rotational speed of the driveshaft into the linear speed of your vehicle, and that is transmitted to you, the driver, through your speedometer. A speedometer that is not working does not enable you to calculate that information and it is possible for drivers to be at a potential risk.
A faulty wiring or fuse
If your vehicle often goes through extreme conditions, temperature, or weather, it is possible that exposed wires can get wet and short out, and that causes a fuse to blow. A broken fuse for the speedometer can cause the speedometer to run down to zero. This inaccurate information may cause drivers risk, so it is best to get such an error fixed immediately.
A broken speed sensor
A speed sensor has many purposes. It shows the speed of the vehicle, regulates the flow of fuel and the ignition timing, and operates the cruise control. If a speed sensor fails, it may cause the speedometer to not work.
Some of you may notice that the vehicle is not running smoothly, and you are unable to use the vehicle’s cruise control. When the speed sensor fails, it causes the check engine light to come on, indicating that there is an issue.
A malfunctioning control unit
The control unit for the speedometer is a part of the transmission control module. It connects to the sensors in your vehicle and communicates with the car’s computer. The problem may be that there is an issue with this component, which may cause a malfunction in your speedometer.
If there is a problem with the control unit, it might affect the vehicle’s ability to recognize the speed at which it is traveling, and the speedometer might be reduced to zero even if this is not the truth.
A broken wire harness
A wire harness usually runs through all of your car’s components and parts such as fuses, wires, and other electrical components within your vehicle’s electrical system.
If there is a broken wire harness in any of these places, it will interfere with the transmission control module and lead to many issues. This can include, among others, bad battery connections, poor performance from some of your car’s features, and even lack of power for other parts of your vehicle.
Take it to the repair shop
In any case, it is best to take your vehicle to a mechanic and have it checked out. It may be possible that the problem lies with a more ingrained issue within your vehicle, so it is best to have it fixed by a professional.
