This is really annoying! My Hyundai Sonata did not start this morning when I tried to start it. Before, everything appeared fine. Why wouldn’t a Hyundai Sonata crank?
In less than two minutes, find out if your auto insurance is being overcharged.
I’m sorry to hear that starting your automobile is a challenge for you. There are a few potential causes for your Hyundai Sonata’s starting problems. The most likely explanation is that your battery is dead or broken.
A Hyundai Sonata won’t start most of the time simply because the battery is dead. Fortunately, fixing this problem is also the simplest. You almost probably have a dead battery if none of the electrical systems turn on. Attempt to jumpstart your Hyundai. The likelihood that this will solve the problem is fairly high.
If jump-starting doesn’t work, your battery can possibly be harmed. Check the battery visually for any signs of damage. The problem is most likely being caused by it if it is bloated, leaking, or showing significant corrosion near the terminals. Sometimes you can use baking soda to clean the terminals on your own. You all require a new battery for any additional damage.
You most likely have a damaged alternator or a malfunctioning starter if you are certain the battery is in fine operating order. You all need to have the broken part fixed or replaced by a mechanic.
While dealing with a dead battery can be frustrating, overpaying for auto insurance is much more annoying! Thankfully, checking and changing your auto insurance is quicker and simpler than jump-starting your vehicle.

faulty battery
The most likely cause of a Sonata’s engine not starting or starting extremely slowly is a weak or dead 12v battery. If the starting issue is related to the battery, further investigation and a battery voltage test will reveal this. You can do a test to measure the voltage between the battery poles, check the acid level, and evaluate the starter battery’s condition.
If a new automobile battery was installed, it’s possible that it hasn’t yet operated to its maximum potential. Nothing to be concerned about. A brand-new battery can only reach its maximum capacity with time.
What could be the reason a Hyundai Sonata won’t start making noises?
Your battery is dead or your alternator, which charges the battery, is malfunctioning if your Hyundai Sonata won’t start and makes a clicking noise. The starter, a small motor powered by the battery that starts the engine, is unable to maintain power if the clicking noise is electrical in origin. Make sure your battery’s connections are tight and corrosion-free by checking them. The alternator is probably not keeping your battery charged if the engine starts but soon shuts off. A dead battery is probably the cause if a jumpstart keeps Your car running but it won’t start again on its own power. The majority of car parts retailers, including Advance Auto Parts and Advance Auto, offer free battery and alternator tests. When you buy a battery from a parts store, they’ll also install it for free.
The 2018 Hyundai Sonata’s clicking noise could be brought by by a broken starter or battery.
Why did a Hyundai Sonata turn off while it was moving?
Transmission malfunction: The torque converter, which replaces the manual clutch in a car with an automatic transmission, is in charge of transferring power. The converter won’t function properly if the torque converter is damaged or if the transmission fluid level is low; as a result, the vehicle won’t be able to sustain power at low speeds, which results in the engine cutting out. This problem can also be brought on by a broken torque converter solenoid or TCS.
The fuel pump is in charge of moving fuel from the tank to the engine regardless of low fuel pressure, filthy or damaged fuel injectors, or a faulty fuel pump. Low fuel pressure from a damaged fuel pump can lead to an uneven stream of fuel being delivered to the engine. This doesn’t matter as much at high speeds, but at low speeds, even a little interruption in the fuel delivery might cause the engine to stall. A precise amount of fuel is sprayed out by the fuel injectors, and at the right moment, it is ignited by the spark plugs. Over time, injectors can get clogged or unclean, which causes irregular spray or no spray at all.
Bad oxygen sensor or mass flow sensor: The oxygen sensors and mass flow sensor let the vehicle adjust the air-to-fuel ratio by detecting how much oxygen is entering the fuel stream. Your vehicle won’t run as efficiently if the oxygen level is too high or too low. The car will continue to run at driving speeds, just like with low fuel pressure, but this insufficient power won’t be able to fuel the vehicle when it slows down.
Wires that are loose or rusted in the wiring harness: An ignition that fires inconsistently will cause an easily stalled engine. The vehicle can quickly lose voltage and won’t have the power it needs to remain running when you slow down if the wires are not in steady, dependable, and consistent contact with the ignition circuit.
Idle air control actuator malfunction: During idling, the engine’s RPMs are controlled by the idle air control actuator. The electronic control unit (ECU) sends information to this actuator, letting it know what RPM to keep the engine at for a secure and smooth idle. When the actuator is broken, the engine is not sent a signal for the idle speed and shuts off.
EGR valve obstruction or restriction: Depending on whether the EGR valve is jammed open or closed, a clogged, unclean, or damaged EGR valve might cause your automobile to stall, idle incorrectly, or sputter.
Why won’t my Hyundai key turn?
If it isn’t, reopen the case and check to make sure the connections are intact and touching the battery in the proper location. Try reprogramming your Hyundai key fob after that. Hyundai key fob replacement may be necessary if the key fob is still inoperable.
My car won’t start, but the battery is fine. Why?
Your starter may be the issue if the battery appears to be in good condition. A starter is a little motor that uses battery power to pull current in order to start an engine. When you turn the key in the ignition, you can hear a clicking sound if the starter fails or malfunctions. In some cases, loose connections are the issue, while in others, a new starter may be required. There is no assurance that jumping a car will fix starter issues.
How much does a Hyundai Sonata starter cost?
Estimated cost to replace the starter on a Hyundai Sonata. Hyundai Sonata starter replacement typically costs between $397 and $517. The cost of labor is expected to be between $86 and $109, while the cost of parts is between $311 and $409.
How come I have electricity but my car won’t start?
If your headlights work but your car won’t start, your battery is charged but the starter or ignition isn’t working properly. A starting engine can be jumped using a charged battery if the starter or ignition is the issue.
How is a Hyundai Sonata battery charged?
- To make sure your car is completely charged and functional, drive to the closest charging station.
You should consult a professional if this issue persists or your car isn’t charging properly since you might require a new 12V battery or a conventional jumpstart.

Why won’t my car start after it switched off while I was driving?
When you find yourself in this scenario, safety should always come first. Your safety and the safety of those using the road nearby are of utmost importance. Once you are secure, quickly search for any hints as to why this is taking place. The following advice could assist you in securely exiting this predicament:
Move the vehicle off the road or all the way to the right side. The hazard lights should be activated first to alert approaching vehicles that there is an issue with your car. Even though the steering may be difficult, do your best to manage it and use the handbrakes to park the car because the regular brake pedal won’t function properly.
You have a problem with the battery charging system if the dashboard warning light is on. The alternator or the battery itself may be the issue. Verify the electrical connectors, terminals, and systems. If not, tighten the drive belt again or inspect it for damage.
Examine the gasoline filter if the automobile dies while moving but then restarts. It might also be the result of a fuel pump that isn’t strong enough to maintain a consistent pressure. To quickly locate and identify the defect, check the fuel pressure and the gasoline lines.
When a car stops while being driven and then restarts later or after cooling down, there is an issue with the engine management system. In this situation, you must carefully inspect the position sensors. Examine the crank position sensor since a malfunction causes it to give the crankshaft the incorrect position, which causes a misfiring sequence that causes the engine to stall.
How much does a Hyundai Sonata car battery cost?
Estimated cost of replacing the battery in a Hyundai Sonata. Hyundai Sonata batteries typically cost between $268 and $275 to replace. While parts are priced at $242, labor costs are predicted to be between $26 and $33.
How long do the batteries in a Hyundai Sonata last?
The normal battery life of a 2021 Hyundai Sonata is 3 to 5 years, although actual battery life might vary greatly based on factors including battery size, battery type, weather, and driving behavior. Even so, a partially charged battery does not necessarily indicate that it is performing at its best.
Why did my automobile suddenly stop?
Crankshaft position sensors that are malfunctioning or fuel system problems are the most frequent causes of vehicle shut-offs while in motion. It can also occur as a result of a faulty alternator, ignition switch, empty gasoline tank, or problems with the car’s engine sensors.
What sensors could prevent an automobile from starting?
Frequently, a malfunctioning crankshaft or camshaft sensor is to blame for an engine that will turn over but not start.
All contemporary engines are loaded with engine management sensors that provide real-time data to the ECU. Both good and terrible things may result from this. On the one hand, having a diagnostic reader and knowing what to look for can make it much simpler to diagnose a problem.
A malfunctioning sensor, on the other hand, can produce erroneous readings and leave you stuck on the side of the road.
The camshaft sensor, crankshaft sensor, mass air flow (MAF) sensor, manifold absolute pressure (MAP) sensor, and throttle position sensor are the most typical sensors that prevent your automobile from starting.
Each time the intake valve on cylinder number one opens, a signal is transmitted to the ECU by the camshaft position sensor. The Crankshaft Position Sensor (CKP) signal and that information are then used to determine when the intake valves on the remaining cylinders are opening. When an engine begins, a defective camshaft sensor won’t be able to precisely determine the position of the camshaft, which may result in a misfire or possibly prevent the engine from starting at all.
P0340 and P0335 error codes are frequently set off by issues with the camshaft and crankshaft sensors, respectively.
as already mentioned. The air entering the intake manifold is being watched by the mass air flow sensor. By continuously measuring the air pressure, the manifold absolute pressure (MAP) sensor keeps an eye on the air in the intake manifold. The fuel delivery rate is set by the ECU using the readings from the MAP and MAF sensors. The engine will run rich if either one or both of these measurements are abnormal. The engine will typically stall or misfire as a result of this. Additionally, while the engine is attempting to start, it may flood.
The check engine light will frequently illuminate and the error number P0106 will be stored in the ECU if the MAP sensor fails.
