Kia Sedona Common Problems and Solutions
Trouble Starting The Engine
Problem:
You are struggling to get the engine to turn over.
Solution:
This could be a few issues, but on the Sedona, it's very likely to be a defective vehicle immobiliser control module. Replacing with a new one is a challenging job, but you can find a new control module on our parts page, and there are a lot of tutorial videos available online.
Difficulty level
Noisy AC
Problem:
Your AC is excessively noisy when it's turned on.
Solution:
The idler and tensioner pulleys on the Sedona's AC alternator belt are renowned for rapid wear and may break entirely. Although some drivers are content to live with the noise, you can find replacement idlers and a tensioner pulley in our online store and easily install them.
Difficulty level
Engine Misfire
Problem:
The engine is misfiring regularly.
Solution:
This will often be caused by cracked ignition coils, and if you don't resolve the problem, then it will lead to your catalytic converter melting. If only one of your coils has cracked, it's a sign that the others are also on the way out. You'll need to have a new ignition coil pack delivered by BreakerYard, but installation is very doable.
Difficulty level
Non-Functioning Gears
Problem:
You are struggling to make smooth gear changes. Sometimes, the gears drop into 3rd when you're driving on the motorway.
Solution:
The output sensor that sits at the top of the transmission is prone to premature wear and is likely to be one of the first parts of your car to fail. If you're in an emergency situation, then you can temporarily resolve the issue by turning the car off and letting it cool down. However, you will need to order a new sensor from our parts page, but it's an easy and low-cost fix.
Difficulty level
Malfunctioning Turn Signals
Problem:
Your turn signals only work occasionally or may not work at all.
Solution:
This is a common issue with the Sedona and is being caused by a faulty switch in the selector lever. You can try to replace the switch itself, but this is a very delicate and fiddly job. It's a lot easier to find a new selector lever on our parts list and replace the entire thing.
Difficulty level
Noisy Braking
Problem:
The brakes make a squealing noise when applied.
Solution:
Early models of the Sedona were fitted with a front disc and rear drum braking system that has caused a lot of brake issues. Uneven brake callipers are the cause of the squealing noise, while also causing uneven brake pad wear. A new brake system was designed and released by Kia, which you can order directly from BreakerYard.
Difficulty level
Leaking power steering pipes
Problem:
If you have noticed drops of red oil on the ground underneath the vehicle, it is most likely caused by leaking power steering pipes.
Solution:
You will need to replace the power steering pipes to fix this problem.
Difficulty level
Air conditioning problems
Problem:
Are you having problems with your air conditioning system? The condenser is known for failing which can result in the air conditioning not working. A common symptom of a faulty condenser is for the air conditioning only to work on one or a few settings, but not them all.
Solution:
You will need to replace the condenser to sort the issue.
Difficulty level
Poor engine idling
Problem:
Is your engine idling very badly? Has the engine management warning light appeared on the dashboard? If yes to one or both of these questions, there is a good chance that the throttle position sensor is faulty. You will most likely be noticing that there is a hesitation when you are trying to accelerate.
Solution:
You will need to replace the throttle position sensor to fix the problem. Watch the video below to see how this is done:
Difficulty level
Fuel pump failure
Problem:
The fuel pump is prone to failure on the Sedona. If this part fails you will notice a lack of power when you press your foot on the accelerator. You will get surges of power and then lose power again, which will result in the fuel pump breaking up and the metal pieces entering into the fuel system potentially causing severe damage.
Solution:
As soon as you notice this problem on your vehicle you should get it seen to asap to avoid any further damage to your Sedona. Fitting a replacement fuel pump will solve the problem. We can help you find a replacement fuel pump at a very low price.
