What Are Common Hyundai Electrical Problems?
Â
As a Hyundai owner, you will eventually run into issues with your car related to its electrical system. Many drivers visit our team at Colonial Hyundai for their Hyundai electrical problems and concerns, which we are more than prepared and equipped to tackle. In this post, we will take the time to explain the common Hyundai electrical problems you should keep an eye out for, plus share some tips on what to do following odd sounds, smells, or performance. Stick around as we dive into this topic below!
Is It Common to Experience Hyundai Electrical Problems?
No, Hyundai vehicles are not known to have frequent electrical problems. However, any car that gets older will experience some electrical wear and tear, which is entirely normal. Specifically, you can expect Hyundai electrical problems mainly with the battery, alternator, and starter, which are the three main parts of this system.
Battery Issues
Hyundai batteries should last about five years in your car, truck, or SUV. Beyond that point, you will likely need a replacement. The friendly pros at Colonial Hyundai in New London are here for your battery testing and replacement, so please reach out to us if you are having trouble starting or maintaining power inside your car.
Alternator Problems
The alternator might also be to blame if you experience Hyundai electrical problems. This will result in dimmed or flickering interior/exterior lights, dashboard lights dimming and flickering, and a rapidly draining battery.
Starter Motor Malfunctions
Because the starter motor of your Hyundai is responsible for turning the engine during ignition, any issues with it under your hood could lead to misfiring. The starter motor is the final cherry on top of the electrical system, so it needs annual check-ups, too.
Clicking Noise When Starting
Strange sounds can indicate Hyundai electrical problems, big and small, so it is best not to ignore them. The most common sound people hear from their Hyundai with an electrical issue is clicking, indicating a problem with the electricity or power running through your car. Some may describe this as a ticking sensation as well.
Difficulty Starting the Vehicle
If you have a slow engine crank or find your Hyundai misfires when you start, you could have an auto electrical problem. As we shared, the electrical components inside your Hyundai help start and maintain the engine on the road, plus your lights, infotainment, safety, and climate capabilities.
Blown Fuses
Another indicator of Hyundai electrical problems is a blown fuse. This usually happens because a small, replaceable component within your car's electrical system has melted due to an excessive flow of electrical current and needs to be swapped out.
Wiring and Connection Issues
The wires and component connections under your hood are crucial in everyday starting and driving. These can become damaged by fluid leaks, age, weather, and heat, so our team at Colonial Hyundai is happy to get an inspection started under your hood whenever you need one.
Faulty Sensors
Sensor problems often impact the engine's ability to start, maintain temperature and oxygen levels, and direct energy to the rest of your vehicle. Specifically, the crankshaft position sensor can malfunction, causing your engine to stall and fail to accelerate.
Issues with Throttle Position or Mass Airflow Sensors
Hyundai electrical problems with the throttle position or mass airflow sensors can cause a domino effect while starting and driving your car, truck, or SUV. We see issues like poor engine response, rough idle, sluggish acceleration, decreased fuel economy, and a check engine light on the dash when a sensor becomes damaged or stops working correctly.
Malfunctioning Oxygen Sensors
Your engine has to have oxygen, much like humans, so your driving ability will be impacted if the oxygen sensor under your hood does not work correctly. A Hyundai with a malfunctioning oxygen sensor might produce more smog than usual, smell bad, make strange sounds, and cause power surges throughout your vehicle, so this is something to be proactive with.
Lighting Problems
The most apparent symptom of Hyundai electrical problems is failing, flickering, or dimmed interior or exterior lights. This can affect your headlights, tail lights, turn signal lighting, infotainment brightness, and dashboard, all pointing at a malfunctioning electrical system.
Infotainment System Glitches
If your Hyundai has a touchscreen or display area that relies on the electrical system to operate, issues with connections and power levels will impact everyday use. You might notice dimmed screens, glitching, system overdrive, and complete shut-downs.
Power Window and Door Lock Failures
Many drivers do not realize that their power windows and door locks rely on the electrical system. Therefore, if you are having Hyundai electrical problems on or off the road, your windows might be unable to roll up/down, and your locks could stop responding.
Electrical Component Drain
Another interesting thing that can happen to a Hyundai's electrical components when there is a problem is drainage. We call this "parasitic drain," which explains the phenomenon of your electrical system still being on and using its energy when your Hyundai turns off. This can speed up dead batteries, connection failures, light burn-outs, and more.
Importance of Regular Maintenance
One of the best ways to prevent a major Hyundai electrical malfunction is to schedule routine maintenance with a certified and authorized Hyundai service center. The friendly team here at Colonial Hyundai of New London regularly sees people experiencing electrical failures and malfunctions; plus, we can run diagnostics on your car and get started with a replacement as soon as the same day.
