Overview

Claim against Kia

Affected vehicles

Overview

‍

On 15 February 2023, class action proceedings were commenced against Kia (the Australian entity, Kia Australia Pty Limited, and its South Korean parent, Kia Corporation) in the Federal Court of Australia in relation to defective engines in various Kia vehicles sold in Australia from 2011 to date.

The proceedings are action no. NSD 132 of 2023 in the Federal Court of Australia.

‍

The action is being funded by Woodsford, a leading global ESG, access to justice and litigation finance business. The applicants are represented by law firm Johnson Winter Slattery.

A separate but similar proceeding has also been commenced against Hyundai.

‍

Kia filed its defence to the claims in July 2023. In its Defence:

Kia admits that a small number of Kia Optima and Sorento vehicles were subject to a manufacturing process in which there was risk that excessive swarf would remain in the crankshaft assembly. Kia says that it recalled all of those vehicles so that they could be inspected and so that any engine found to contain excessive swarf from the manufacturing process (which could lead to some of the faults alleged in the claim) could be replaced;
Kia admits that the engines in a small number of Kia Seltos vehicles were manufactured using brittle piston rings. Kia says that it recalled all of those vehicles so that they could be inspected and so that any engine found to contain cracks in the piston rings leading to scuffing of the cylinder bores (which could lead to some of the faults alleged in the claim) could be replaced;
Kia admits that, until they were repaired, the above vehicles did not comply with the statutory warranty of acceptable quality;
Kia admits that, until they were repaired, the above vehicles did not comply with the express warranties pleaded in the claim;
Kia admits that, until they were repaired, it made misleading or deceptive representations in relation to the above vehicles that they were of good quality, reliable, durable, fit for purpose and safe;
but Kia says that owners of the above vehicles are not entitled to recover damages for any reduction in the value of the vehicles because Kia has remedied the failure;
Kia also says that any failure in relation to the piston rings occurred only because of the act, default or omission of the supplier of the piston rings; and
other than in respect of the limited group of vehicles referred to above, Kia denies all of the allegations.

‍

As at September 2024, Kia has been ordered to produce further documents over the next six months. Class action litigation can be a slow process, and we thank you for your patience. Please see the ‘Key Events’ page for a more detailed timeline of the proceedings.

If you own an Affected Vehicle covered by the Kia Engine Class Action and have recently experienced a serious engine failure (i.e. your vehicle is undriveable in its current state, and the engine needs to be replaced or repaired), please email us at contact@kiaengineclassaction.com.au and tell us about your engine failure. An inspection of your vehicle may be of assistance in the conduct of the class action. We can discuss with you further what would be required to facilitate this. We note that we are currently primarily looking to inspect vehicles of those group members who reside in New South Wales. If your engine has already been repaired or replaced, there is no need to contact us unless you still possess the failed engine. Don’t forget to register your interest if you haven’t already!

Claim against Kia

‍

The action alleges that numerous vehicles sold by Kia in Australia since 2011 (see the list below) were sold with engines that were manufactured and/or designed defectively and, as result, have the propensity to exhibit faults, including:

knocking or tapping sounds;
internal damage to the engine;
increased oil and/or fuel consumption;
sudden loss of power (including while driving) and engine failure;
the emission of smoke from the engine compartment; and/or
in some cases, fire.

‍

As a result, the action alleges that the vehicles sold by Kia:

failed to comply with the statutory warranty provided by the Australian Consumer Law that goods sold to consumers are of acceptable quality; and
failed to comply with the express warranties contained in their advertising material about the vehicles’ quality, reliability, durability and safety.

‍

In addition, it is claimed that Kia had or accumulated knowledge of the engine issues since at least 2015 (when various recall notices were first issued for similar vehicles in the United States), but continued to sell them in Australia without notifying the Australian car buying public (except for a very limited Australian recall campaign). It is alleged that Kia engaged in misleading or deceptive conduct in advertising and promoting the vehicles in Australia as being good quality, reliable, durable, fit for purpose and safe.

The class action seeks damages and compensation on behalf of all group members.

You may be a group member in the class action if between 1 January 2011 and 15 February 2023:

·      you purchased or leased an Affected Vehicle (see the list of Affected Vehicles here); and
·      you did not acquire the Affected Vehicle in an auction; and
·      you did not acquire the Affected Vehicle for the purposes of re-supply; and
·      you acquired the Affected Vehicle from a Kia dealership or other retailer (such as a used car dealer) or from any person who acquired the vehicle directly from a Kia dealership or other retailer.

If you meet the criteria described above, and your vehicle is one of the Affected Vehicles with the necessary engine type, then you are automatically a group member and do not need to take any further steps to become one. Group members will be bound by the outcome of the class action unless they take steps to “opt out” of the Proceeding.

If you think you may be a group member, but are not sure, we encourage you to register your details here.

8. Do I need to register or sign up to be a group member?

No, anyone who acquired an Affected Vehicle (see the list of Affected Vehicles here) and otherwise satisfies the relevant criteria is automatically a group member unless and until they opt out of the class action. However, if you think you may be a group member, we encourage you to register with us here, which will make it easier for us to contact you and provide you updates and notices in relation to the class action. It will also mean that we have your contact details on record in the event there is an outcome (such as a settlement or a judgment of the court) which results in damages being awarded to group members.

9. I have registered for the class action. What do I need to do now?

At this stage, we are still processing registrations. The Court has not yet made any orders in relation to specific communications with group members. There are no further steps you are required to take at this time. You will be informed in due course when any further action is required.

10. I bought my vehicle second hand. Am I a group member?

The proceeding has been commenced on the basis that individuals who acquired an Affected Vehicle second hand may be group members so long as they acquired the Affected Vehicle:
·     from a Kia dealership;
·     from another retailer (such as a used car dealer); or
·     from any person who acquired the vehicle from a Kia dealership or other retailer.

You will not be a group member if you acquired the Affected Vehicle at auction or for the purposes of re-supply, or from a person who acquired the Affected Vehicle for the purposes of re-supply.

11. I’ve already sold my vehicle. Am I a group member?

Yes, so long as at the time you acquired the Affected Vehicle you met the criteria described in the answer here, you will be what is called a “Group B Member” in the proceeding.

12. I have not experienced any issues with my vehicle’s engine yet. Am I a group member?

Yes, so long as at the time you acquired the Affected Vehicle you met the criteria described in the answer here.

13. I am currently experiencing problems with the engine in my Kia – what should I do?

If you own an affected vehicle covered by the Kia Engine Class Action and are currently experiencing problems with the engine of the kind described above, you should first contact Kia and/or your local Kia dealer about the problems to see whether Kia is willing to repair your vehicle (whether your vehicle is still under warranty or not).

If your engine has recently suffered a serious failure (such as a complete engine failure or fire) and has not yet been replaced, please also contact us at contact@kiaengineclassaction.com.au as an inspection of your vehicle may be of assistance in the conduct of the class action. We can discuss with you further what would be required to facilitate this.

If you have the problems with your vehicle inspected or diagnosed by a Kia dealer or other independent mechanic or expert, you should seek a report of their findings in writing and retain a copy, together with any records of the costs you incurred in relation to the inspection.

If you have your vehicle repaired, you should keep copies of all records and communications associated with the repair and the costs of the repair (including associated costs such as loan car or transport costs, loss of income, etc. while you are without the use of your vehicle while it is being repaired).

If Kia is unwilling to repair your vehicle without charge, and you are unable or unwilling to pay the cost to repair your vehicle yourself (including potentially replacing the engine), you should keep copies of all records and communications associated with the costs you incur as a result of the engine problems, such as the costs of purchasing a replacement vehicle or using alternative transport (such as public transport or a loan car), loss of income, etc. while you are without the use of your vehicle. We also recommend that you keep records of all of your communications with Kia and/or the relevant Kia dealer in relation to your vehicle.

If you decide to sell your vehicle, you should keep copies of all records and communications associated with the sale, particularly if the price you are able to sell your vehicle for is less because of the problems you are experiencing with the engine.

14. I do not want to be a group member. What do I do?

The proceeding is an “open class action”, meaning the applicants have commenced the class action on behalf of all group members. In an open class action, any group member who does not wish to participate must “opt out” of the class action. This process is regulated by the Court and will most likely involve all group members receiving a notice in due course which describes how they can elect to opt of the proceeding if they wish to do so.

15. What will it cost me to be part of the class action?

Group members will not be responsible for legal costs incurred in the prosecution of the claims against Kia by the applicants.

16. How long will the class action take?

It is not possible to say exactly how long the proceeding will take. The proceeding was commenced on 15 February 2023. Class actions can be quite long, and could take anywhere from six months to several years for the claims to be heard and determined or otherwise resolved.

17. Who are the lawyers running the proceeding?

Johnson Winter Slattery are the solicitors on the record in the proceeding for the applicants.

18. I have registered for the class action. Can the Kia Engine Class Action Team provide me with individual legal advice?

‍
We also recommend that you keep records of any communications with Kia and/or the relevant Kia dealer in relation to problems you are having with your vehicle.
