Hyundai’s Push-Button Start Issue Is Still Present
Is your Hyundai’s push-button start malfunctioning? Have you been left stranded by your Hyundai’s keyless start issues because it won’t start?
We routinely write about the problems Hyundai drivers face, including vehicle alignment problems and transmission problems.
A new issue with the Hyundai push button start is now approaching.
People who are been left stranded by the Hyundai push button start issue are flooding the message boards in droves.
The problem is caused by the brake pedal sensor failing. A driver should ideally depress the button while keeping their foot on the brake. The Hyundai should start without a hitch as long as it detects a key fob nearby (in a pocket or handbag). However, it appears that the brake pedal’s sensor is broken. Due to the car’s inability to recognize that the driver has their foot on the accelerator, it won’t start.
Many of the drivers we are aware of are returning to their Hyundai dealer on a frequent basis to address this issue, and some people have been informed there is no cure because it is intermittent. Some people have been told that the issue would resolve itself. This is not true.
We think that because the manufacturer has not yet found a suitable solution, many more Hyundai drivers may experience the push-button start issue in the future. Numerous drivers can end up stranded in driveways, parking lots, and petrol stations as a result of this problem.
It’s crucial to maintain track of your repair bills if you’re experiencing Hyundai push-button start issues and to continue receiving warranty service until the problem is fixed. If you discover that you have visited the shop numerous times to address the issue, research your rights under state lemon laws (including those in New York and New Jersey) and federal warranty regulations, and then get in touch with a lemon law attorney in your state who might be able to help.
There are ten potential causes if your Hyundai Sonata won’t start.
Your battery, battery terminals, key fob battery, starter, alternator, fuel filter, fuse, spark plug, or engine could all be at fault if your Hyundai Sonata won’t start.
One of the top-selling midsize cars, the Hyundai Sonata draws a large number of buyers each year. If you drive a Hyundai Sonata, you must be prepared to deal with starting problems and arm yourself with temporary fixes to restart your vehicle.
Starting issues can have a variety of causes. Some of the causes might be straightforward, and they might only require minor fixes that you can perform on your own. Other causes, however, can be more problematic and necessitate prompt assistance from a qualified mechanic.
This page discusses every conceivable cause of a non-starting Hyundai Sonata. We provide you some advice and pointers to help your Hyundai Sonata temporarily start up. To fix and avoid any recurring problems with your Hyundai Sonata starting system, you must take a second step and adhere to the long-term fixes.
We know how frustrating it is to turn the key in the ignition and just hear clicking noises coming from your Hyundai Sonata. Hyundai Sonata starting problems might occasionally be more challenging because you want to see any car response when you turn the key in the ignition switch.
Nothing happens when I try to start my car?
When the ignition is turned on but no lights illuminate on the instrument panel, there is no power coming from the battery. It can be a blown main fuse, a broken ignition switch, a dead battery, or a loose battery terminal.
If the headlights come on, the battery has electricity, so the ignition switch, fuses, or wiring between the ignition switch and battery could all be at fault. The battery can be fully dead if the headlights don’t function. The battery can be charged; find out how below.
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.
Why would my car suddenly stop starting?
A fading or dead battery, frayed or corroded connecting cables, a defective alternator, or a problem with the starter are the common culprits when a vehicle won’t start. It can be challenging to distinguish between a battery or alternator issue.
My car won’t start, although it has power. Why not?
faulty spark plugs If your car won’t start even though the fuel system is operating well and the engine maintains compression, your spark plugs may not be functioning properly. Inside the engine’s cylinders, the spark plugs ignite the fuel/air mixture. The explosion that results from this is what truly propels your car.
Why do the radio and lights work in my car but not the engine?
A click indicates that the solenoid is activated and engaged. The starter motor itself, however, is currently being stopped from rotating by something.
A battery that is only partially charged is the most likely problem. The lights and radio are operating, so it must still have some power, but the starter motor uses a lot of current. Starting the car requires much more energy than, say, running the headlights.
Thus, even if the battery is almost entirely depleted, the lights and radio may still function. You probably won’t see bright lights here (including the dashboard lights). Higher volumes may potentially cause the radio to have trouble.
Use a multimeter across the two terminals to assess the battery’s health. In a perfect world, you’ll be seeking 12.6 Volts (exactly). The battery needs to be replaced if you see anything dropping to or exceeding 12.0 Volts. It doesn’t maintain a charge long enough to start your vehicle.
An alternative would be to employ a battery tester. You can determine the battery’s state from this. Once you have the car running, you may use it to test the starter and alternator.
When your car won’t start but the battery is still functional, what does it mean?
The car may not start even when it clicks when attempting to start due to a weak battery, filthy battery terminals, a damaged starter motor, or a blocked solenoid. There are a few techniques to try before using the jumper cables or electric jump starter even if it could just need a jump start.
Why won’t my car start and why is my brake pedal stiff?
The majority of contemporary automobiles include power assist, which depends on a brake vacuum to function. If you’ve been applying pressure to the brakes while the engine is off, you may have exhausted the reserve vacuum in the vehicle. As a result, your brake pedal will become stiff.
When your automobile clicks but won’t start, what happens?
When trying to start your car, a loud clicking sound may indicate an issue with the electrical system. It’s possible that your battery is dead or that the alternator, which charges the battery, is malfunctioning.
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. Instead, it makes a clicking sound and switches on and off quickly.
Remember that in situations like this, a misfiring starter is really a symptom and not the root of the problem. Your automobile’s electrical system is probably to blame, which is why a jumpstart could briefly move your car.
Once it’s operating, have an experienced technician inspect the entire electrical system. Your alternator or battery might need to be replaced. Alternately, the issue might be resolved by simply cleaning the battery terminals of corrosion to improve the battery’s connection.
You’re not the only one having issues with your automobile battery. According to AAA, among the top three reasons members call for roadside assistance are battery issues, with the majority of those calls occurring in the summer.

When I turn the key in my automobile, why won’t it start?
A dead or malfunctioning battery is the most typical cause of car starting problems.
1 Despite the fact that most cars are fuel-powered, all vehicles need electricity to function. Your engine’s starter needs an electrical signal to fire in order to crank it. 2 Your car’s engine won’t start if your battery has a problem. Although there are other signs that could point to a dead battery, it is always a good idea to see if your engine even turns over.
Dead batteries have the advantage that you can restart your car without the help of a mechanic. Anyone with a basic understanding of mechanics can jump start a car battery. The best course of action is to simply take good care of your battery because battery jumps are only short-term fixes and new batteries can be pricey. Check out these suggestions for preventing a dead battery for more information on how to achieve that.
How is no crank, no start diagnosed?
Turning on the headlights and seeing what occurs when you try to start the engine will help you identify cranking issues quickly. A weak battery cable connection may be stifling the flow of amps if the headlights go out.
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.
