Kia Sorento Won’t Accelerate Causes

Kia Sorento Won’t Accelerate is a serious concern that causes the vehicle to stall. This can be caused by any number of things, but the most common reason is a faulty ECM (Electronic Control Module). The ECM is what prevents the car from running out of gas and stalls the engine.

This large SUV has a powerful engine, and it’s hard to believe that there could be an issue with it. However, several different factors can cause this car to suddenly stop accelerating, including:

  1. Many Kia Sorento owners have reported that the vehicle will not accelerate when the engine is cold, or when the temperature is below freezing. This can cause you to pull into a garage and wait for it to warm up, which is a waste of your time and money. The reason behind this issue is that the fuel injection system in your Kia Sorento may be clogged with ice. If this happens, then your car will not be able to get enough gas to start properly.
  2. The first thing that you should do if your car won’t accelerate is to make sure that there are no other vehicles around it. If another vehicle was parked next to yours, then they could have blocked off some of the airflows into your engine compartment and caused it to stop working properly.
  3. The most common cause of this issue is due to a faulty fuel injector, which is responsible for the fuel supply to the engine. If you are having an issue with your Kia Sorento’s acceleration, you should contact the manufacturer immediately for assistance. You can contact Kia directly at 1-800-847-0700 or through their website at
  4. You should also check all of the electrical connections on your dashboard for any loose wires or broken connections as well.
  5. Faulty fuel pump – The Kia Sorento’s fuel pump is responsible for delivering fuel to the engine. If it fails, the car won’t accelerate at all.
  6.  Faulty ignition coil – The ignition coil provides current to the spark plugs so they can ignite the air/fuel mixture in your engine. If this component fails, you won’t be able to start your car.
  7.  Faulty throttle body – Your throttle body regulates how much air is sent into your engine when you apply your foot to the brake pedal or gas pedal. If this component fails, you won’t get any response from these pedals.

If these things don’t fix the problem, then you’ll need to take your car to a mechanic who can check out the problem for you. A mechanic should be able to tell you what’s wrong with your vehicle and how much it will cost for them to repair it properly.

Kia Sorento Won’t Accelerate Solutions:

If your Kia Sorento won’t accelerate, here are some things you can do to fix it.

  1. Check the fuel pump relay. If this is causing the problem, turn it off and on again to see if that fixes the problem.
  2. Ensure there is power going to the battery and it’s not low. If it is, charge it up before continuing with step 3.
  3. Test all of your fuses one by one until you find which one appears to be bad, then replace them all at once with a good set of fuses from a replacement kit.
  4. Assuming Step 3 didn’t help, check all of your connectors for loose or broken wires and make sure none are damaged or frayed at all (especially around the plug). If any are bad, replace them immediately with new ones from a replacement kit.

FAQs (Frequently Asked Questions)

Q. What Causes a Kia Sorento to Lose Power?

There are several reasons that you might experience a loss of power with your Kia Sorento. Here’s what they are:

  1. The battery is dead: This one happens so often it’s almost not worth mentioning—but if you’ve got a dead battery and no way to charge it, then you’ll be in trouble. Luckily, replacing the battery is easy and inexpensive. Just bring your car into an auto shop and make sure they know what kind of battery you need for your vehicle!
  2. The alternator has failed: Alternators are pretty important parts of any car’s electrical system; if one fails or stops working properly, it can affect the other parts of the car’s systems as well. If one part goes bad, others will start malfunctioning as well. Suppose you notice that the car starts having issues after driving for a while without using its lights or accessories like music players or navigation systems (or even just turning on lights). In that case, this could mean that your alternator has failed.
  3. The wiring inside the engine compartment has gotten loose

Q. Why Is My Car Not Picking Up Speed When Accelerating?

If your car isn’t picking up speed when you accelerate, it could be because of one of the following:

  • Your transmission is out of sync.
  • Your transmission is dirty and needs to be cleaned.
  • Your transmission doesn’t have enough fluid in it (check your fluid level).
  • You need to adjust your gas pedal or clutch pedal to make sure they work properly together.

  • Make sure you have gas in the tank. Gasoline has an evaporative quality that causes it to slowly seep out of the tank and into the engine. If you don’t have gas in the tank, your car will not pick up speed when accelerating.
  • Check your rotors and brakes to see if they are damaged or worn out. This can cause them not to provide enough friction between the wheels and the ground—meaning there’s no way for your car to accelerate!

Q. Why Does My Car All of a Sudden Have Reduced Engine Power?

If your car has suddenly lost engine power, it’s probably due to the following reasons;

  1. You probably have a clogged gas filter. The gas filter screens out impurities from the fuel supply line and keeps them from entering the engine. If it gets clogged or damaged, the impurities can get through and cause reduced engine power.
  2. So how do you know if your gas filter is clogged? You can use a flashlight to look at the bottom of your fuel tank and see if there’s any sediment or dirt collecting in there. If so, clean it out right away! Then check your fuel filter every month to make sure it’s not getting clogged up again.
  3. Low oil pressure in the engine could be causing a loss in engine power.
  4. Check your oil level, and if it’s too low, add more oil.
  5. If your gas tank is empty and you haven’t recently filled up with gas, it could mean that there is not enough air flowing through the engine to provide enough oxygen for combustion to occur properly. You can check this by pumping the accelerator pedal gently several times and then checking if there is any visible light from under the hood when you do so. If not, consider filling up with more air before driving again!

Q. What Are the Symptoms of a Failing Throttle Body?

If your car is experiencing a failing throttle body, there is a chance that it will experience a variety of symptoms. Here is a list of possible symptoms:

  1. Rough idle – This can occur if the throttle body is failing and it is not opening or closing correctly. If your car is idling rough, it may be difficult to start or stop and you may notice that you have trouble accelerating when driving.
  2. You have a hard time accelerating from a stop – You have difficulty shifting gears smoothly. Your vehicle has a hard time stopping and you feel like the engine is lagging when you accelerate
  3. You notice a decrease in power when you accelerate – You hear a grinding or screeching noise when you try to accelerate from a stop
  4. The engine RPMs drop after you turn off the ignition, then gradually rise again
  5. You hear a clicking sound when you accelerate – You hear a rattling or knocking noise that gets louder when you accelerate – Your vehicle vibrates more than usual when driving

Q. How Do I Get My Car Out of Limp Mode?

Your car may be in limp mode if it won’t start. If you’ve tried starting your car, but it doesn’t start, check the following:

  • Check that all of the lights are working and that you can see the dashboard in front of you. A blinking light is a bad sign.
  • Check your battery’s fluid level with a hydrometer test kit. The fluid should be between 2/3 and 1/2 full. If it’s not, add some distilled water to bring it up to 3/4 full.
  • Check that your battery cables are tight and in good condition. You can do this by putting your hand on each cable for about five minutes (longer if needed) before trying to start your car again.

If these steps don’t get your car started, contact a mechanic or go to the auto parts store to find out what’s wrong with your engine.
