Why Your Hyundai Santa Fe Won’t Start

Why Your Hyundai Santa Fe Won't Start

Here are all the possible causes behind your Hyundai Santa Fe failing to start when you turn the key in the ignition:

A weak or dead battery

Just like any other car, the number one culprit when it comes to your Hyundai Santa Fe starting problems should be the battery.

If the battery is dead or completely dead, your vehicle engine won’t start. In this case, your vehicle may crank slowly or not crank at all.

Some of the reasons your battery may die include forgetting to turn off your vehicle lights or accessories, or degradation that comes with old age.

If you recently installed the car battery, it may also have not reached its full capacity, so it could be causing dead battery often.

Solution: The easiest fix for a dead battery is to jumpstart it with a healthy battery from another car or using a booster pack.

However, we encourage you to test your car battery with a multimeter to ensure it’s in good working condition.

A healthy battery should read around 12V. Anything below this means the battery could be having issues or is defective and needs a replacement.

Corroded battery connections

If the battery is fine, then you should check your battery connections and terminals for loose connections or corrosion.

The clamp connected to the battery cable may have become loose over time due to road vibrations. This can interrupt proper electric current flow to the starter motor, making the engine fail to start.

Also, corrosion on the terminals may interrupt the proper flow of current and further result in your engine failing to start.

Solution: To know if your battery connections are the culprit behind the no-start problem, you’ll need to investigate. Ensure the clamps are tightly secure on the terminals and the respective cables.

Next, look for signs of corrosion on the terminals (appears as white deposits or silver-green) and clean them with a wire brush and a mixture of water and baking soda.

Defective alternator

If the battery is healthy and its connections are secure, then you should check whether your alternator is defective.

The alternator is a crucial part of your car’s charging system. It helps ensure your battery stays fully charged while providing the necessary electrical power to various systems of your vehicle.

Therefore, if it starts malfunctioning, it can cause problems with your vehicle’s electrical system and even stop the engine from starting due to a dead or undercharged battery.

Some of the key symptoms of a bad alternator include a dead battery, dimming interior lights or headlights, a warning light on the dash, or whining noise produced by the alternator.

Solution: If you suspect you have an alternator problem, we advise you to have it checked by a certified mechanic. A faulty alternator should be replaced with a new one.

Failing starter motor

If the alternator isn’t the problem, check your starter motor. This motor usually has an average lifespan of approx. 150,000 after which it becomes faulty. However, frequently using it can easily shorten its lifespan.

In any case, if the motor starter is failing, it will cause your engine not to start. This is because it has the crucial task of turning your engine over whenever you turn on the key in the ignition.

The most common symptom of a bad starter motor is a clicking sound when you attempt to start your car. Sometimes, you may hear a whirring or grinding noise or no response at all.

Solution: If you think the no-start situation could be stemming from a bad starter, have it diagnosed by a reliable mechanic and the necessary repairs performed. In most cases, a failing starter motor will need to be replaced with a new one.

A temporary fix involves hitting the motor with a hammer or metal tool while turning on your car ignition as shown in the video below

Fuel system issues

Hyundai Santa Fe starting problems can also be tied to fuel system issues. For your engine to start successfully, the fuel delivery system must be able to deliver the needed fuel to the engine for the ignition process.

If there are issues with fuel delivery, you’ll likely experience starting issues in your car.

Some of the common fuel system issues include a clogged fuel filter, issues with the fuel injectors, a faulty fuel pump, or even an empty gas tank.

Solution: To fix a fuel system related problem, you’ll first need to ensure there’s enough fuel in your gas tank and your fuel gauge reads correctly.

Next, put the key on and listen for a humming sound. This is usually the sound of fuel pump. Also, check if the fuel filter is clogged and have it cleaned or replaced with a new one.

Immobilizer issue

Some Hyundai Santa Fe models come equipped with an immobilizer security system. This is simply an antitheft security system, which requires that you must use the correct key to start your car.

If this security system starts to malfunction, it can also make your engine fail to come on. If you have confirmed that everything else is functioning correctly but your car still won’t start, the issue may be in this feature.

Some issues that may trigger the system to malfunction include faulty key/key fb, dead key fob battery, or issues with the immobilizer module or ignition switch.

Immobilizer issues may make your vehicle crank but not start or your car may start randomly.

Solution: If you’re facing immobilizer issues, you should consider resetting it to see if your car will start as before. This involves disconnecting the battery and then reconnecting it after a few minutes.

Other potential causes for the no-start problem in Hyundai Santa Fe include ignition switch failure, ignition system issues, a blown fuse related to the starting system, or even engine failure.

Why Your Hyundai Santa Fe Is Not Starting And Makes A Clicking Sound

Another common starting problem in Hyundai Santa Fe involves the car making a clicking sound and failing to start.

The clicking sound is usually made by the starter solenoid as it tries to engage, but the starter itself fails to act accordingly and turns over the engine.

Why Your Hyundai Santa Fe Is Not Starting And Makes A Clicking Sound

One top culprit behind this issue is a weak battery unable to provide enough power to activate the starter motor.

In this case, you can try jumpstarting your car to see if your engine starts. If it does, then the battery is the issue and you should have it recharged or replaced if it is defective.

If the battery checks out, you may have a faulty starter motor unable to start over the engine. In this case, you should have your starter motor tested by a reliable mechanic and replaced if faulty.

Other likely causes that you might consider include a failing alternator or ignition system issues.

A professional mechanic should be able to diagnose your and find out the exact issue causing this behavior in your car.

Why Your Hyundai Santa Fe Won’t Start And The Brake Pedal Is Hard

You may also be having staring issues where your car won’t start and the brake pedal is hard to push down.

The most common reason why this happens is due to a bad battery. The battery may have run out, or depleted due to lack of use or old age.

There are many other potential reasons behind this issue including fouled spark plugs, clogged fuel filter, worn out starter motor, failed relay switch, or broken alternator belt.

However, issues with your car braking system may also be behind this problem. For instance, the air being trapped in the brake hydraulic system can cause the brake pedal to be locked.

You should also inspect the master cylinders or calipers. These could be causing obstruction, which can then cause excessive buildup of pressure that locks your brake pedal.

Brake parts such as pads and rotors might also be failing and require replacement. Or, you may be low on brake fluid.

Having your vehicle inspected by a qualified mechanic will help you determine if the issues lie in the braking system or the other issues above.

In either case, the professional will recommend the best repairs/replacement to fix this issue.

Why Your Hyundai Santa Fe Won’t Start After Filling With Gas

If your Hyundai Santa Fe fails to start after filling the fuel tank, this could indicate a problem with the fuel system.

For instance, the fuel pump or fuel pump relay could be faulty. A faulty pump is unable to deliver sufficient fuel pressure for starting the engine after refilling.

An issue with the evaporative emissions system can also lead to this starting problem. A faulty EVAP system may create a vacuum in your fuel tank, preventing the fuel from properly flowing to your vehicle engine.
