Kia Sorento Common Problems and Solutions
Coolant leak
Problem:
The coolant overflow bottle tends to crack along the seams. If you notice the vehicle overheating, low coolant levels, or see a wet patch beneath the vehicle, inspect this bottle for cracks.
Solution:
You will need to install a replacement coolant overflow bottle to fix the issue and top up the coolant.
Difficulty level
Crankshaft bolt breaks
Problem:
A known issue on the Sorento and several other Kia models is the crankshaft bolt breaking. This can lead to various problems, including warning lights on the dashboard, starting difficulties, and even the crankshaft coming loose. Watch the video below:
Solution:
You need to remove the broken bolt and fit a replacement to resolve this issue. Watch this video to see how to remove the broken bolt.
Difficulty level
Automatic gearbox problems
Problem:
The automatic gearbox on the Sorento is known for jumping out of gear. This issue is caused by a fault with the electric connectors beneath the box. Do not worry too much, as this is not as big a job as you might think.
Solution:
You need to disconnect the electric plugs beneath the box, clean them, and then re-grease the plugs. Re-fit the plugs, and this should resolve the issue. It is normal for this gearbox to produce a whining noise, so do not be overly concerned about it.
Difficulty level
Black smoke/loss of power
Problem:
Have you noticed black smoke coming from the exhaust? Is there a loss of power when accelerating? If you answer yes to both questions, it is a good indication that the intercooler hoses are failing on the vehicle. This has been known to occur on the Sorento.
Solution:
You will need to replace the intercooler hoses to resolve the issue.
Difficulty level
Grinding Noise When Driving
Problem:
You can hear a rubbing or grinding noise while driving.
Solution:
This is most likely an issue with your driveshaft. It cannot be repaired, so you'll need to order a complete driveshaft replacement from BreakerYard and fit the new one.
Difficulty level
Driveshaft
Vibrations AC
Problem:
When you switch on the air conditioning, it vibrates and makes quite a lot of noise.
Solution:
There have been many reports about this issue, caused by faulty AC compressors. Check our parts list for the Sorento and order a replacement compressor.
Difficulty level
Aircon Compressor
Rattle Coming from Engine
Problem:
There is a rattling noise coming from the engine. The check engine light is also on, and the car might enter limp home mode.
Solution:
The 2005 Sorento has a well-known issue with a faulty timing chain tensioner. Kia has released an updated version, which we have in stock. All you need to do is order the upgraded tensioner and replace the faulty one.
Difficulty level
Tensioner
Engine Cuts Out
Problem:
The engine has stalled, and the warning light is on.
Solution:
Either water or oil has entered the hydraulic ECU and has remained unnoticed long enough to cause an electrical short circuit. You will need to remove and clean the HECU, then install a relay that will isolate the HECU whenever the ignition is switched off.
Difficulty level
Passenger Seat Problems
Problem:
The car does not recognise when a passenger is sitting in the front seat, which means the airbag will not deploy in the event of a collision.
Solution:
This issue mainly affects 2009 models and involves a sensor error that can be troublesome. You can't just replace the sensor; you need to order a completely new seat. We always have plenty in stock and can deliver it to you swiftly.
Difficulty level
Car Seat
Jerking While Changing Gear
Problem:
The car jerks forwards whenever you change gear.
Solution:
If you take the car to a Kia dealer, there's a good chance they'll tell you it only needs a system reset. However, this won't solve the problem because it is caused by a fault in the transmission box. We can supply a replacement transmission box, and you can carry out the repair quite easily yourself.
Difficulty level
Gearbox Transmission
Doors Not Opening
Problem:
You cannot open the doors from outside.
Solution:
This is the result of a new design in 2011, and it caused many problems with the doors not opening. The fault lies with a broken spring inside the locking mechanism. You will need to open the sealed locking device to replace the spring. It is quite tricky to do, but we have the replacement spring in stock for you to order.
Difficulty level
Engine Failure
Problem:
The engine appears to have just died.
Solution:
Regrettably, this is quite common in the Sorento and has impacted many drivers. Catastrophic engine failure around the 115,000-mile mark does occur. The only solution is to order a completely new engine from us and replace the broken one.
Difficulty level
Engine Complete Full
Clunk Noise When Reversing
Problem:
Whenever you reverse, you hear a clunking noise, but the car still drives smoothly.
Solution:
Take the car to a spacious area and test your driveline components by first driving forwards in a large circle at low speed, then reversing in the opposite direction. If you hear a clunking noise, it is likely that your CV joints are worn out, and you will need to replace them. Order CV joints from the BreakerYard store, remove the worn ones, and install the new ones.
Difficulty level
Car Shifts Out of Park
Problem:
The car releases itself from park and will roll if on an incline.
Solution:
The brake-shift interlock mechanism on the 2013 Kia Sorento is often too fragile and tends to crack or chip. Find a replacement mechanism on our parts page and swap out the faulty one.
Difficulty level
Seat Belt Not Latching
Problem:
The seat belt locking mechanism isn't functioning properly and won't secure.
Solution:
Driving without a fully working seat belt is very dangerous, so you'll need to get a replacement from BreakerYard and fit a new one.
Difficulty level
Car Seat Belt
Not Detecting Pedestrians
Problem:
The forward collision avoidance assist system is not detecting pedestrians, raising the risk of an accident.
Solution:
You will need to take the car to a Kia dealer, who will usually update the software in your multi-function camera system free of charge.
