Hyundai Elantra NU engine class action

Hyundai Elantra 1.8L Nu Engine – Class Action Settlement

Hyundai recently agreed to settle a class action lawsuit pertaining to the certain Hyundai vehicles containing the 1.8L Nu engines. The lawsuit alleges that these engines contain a piston defect that can cause engine seizure and stalling. More details from the settlement are outlined below.

What vehicles are included?
Hyundai Elantra (model years 2011, 2012, 2013, 2014, 2015 and 2016), Hyundai Elantra GT (model year 2013), and Hyundai Elantra Coupe (model year 2013) vehicles factory equipped with a 1.8L Nu engine.

For covered Hyundai vehicles the settlement provides a package of potential benefits for consumers that is described in the Hyundai Piston Engine Settlement Notice.

What is this lawsuit about?
The Plaintiffs allege that the Class Vehicles suffer from a defect that can cause engine seizure and stalling. The Plaintiffs also allege that engine seizure or stalling can be dangerous if experienced. The Plaintiffs also allege that some owners and lessees have been improperly denied repairs under the vehicle’s factory warranty.

How do I submit a claim to Hyundai for reimbursement?
Fill out the Claim Form (paper or online), and include the documentation specified on the Claim Form, and submit the Claim Form by any one of the following methods:

• Online:
• Mail: PO Box 9099, Newport Beach, CA 92658
• Email:

The deadline to file a claim is 70 days after the Court grants final approval to the settlement. For example, if the Court approves the settlement on April 19, 2021, the deadline would be June 28, 2021, unless your claim is for rental car or towing costs incurred in the future, in which case you have 70 days from the date those costs were incurred or 70 days after the Final Approval Order, whichever is later. An updated deadline to submit claims will be posted on the settlement website after the Court grants final approval to the settlement.

What reimbursement is available under the settlement?
The settlement relief offered is robust. You may be entitled to some or all of the relief including past out-of-pocket repairs and repair related expenses, including rental cars and towing. Please refer to the Hyundai Piston Settlement Notice (and Hyundai Claim Form) for further details.

When will I receive my reimbursement?
In general, valid claims will be paid as they are approved after the Effective Date. The Effective Date for the Settlement will be the date of the Court’s Order giving final approval to the Settlement if there are no objections or appeals. If there are objections or appeals, the date will be later. When the date becomes known it will be posted at

United States District Judge Susan D. Wigenton will hold a Fairness Hearing on April 19, 2021 to decide whether to approve the Settlement. (The hearing may be rescheduled without further notice. To obtain updated scheduling information, see If the Court approves the Settlement, there may be appeals afterwards. It is always uncertain whether these appeals can be resolved, and resolving them can take time, perhaps more than a year. Please be patient. You may continue to check on the progress of the Settlement by visiting the website or calling (833) 462-8721. Payments under the Settlement will begin once the Settlement has been finally approved by the Court and any appeals from that decision are completed.

What if I have other problems with my Hyundai that are not part of this lawsuit?
According to the lawsuit, those claims are not part of the settlement and are therefore not being released so you may still be able to individually lodge a claim against Hyundai for those issues but an attorney would be able to provide legal advice.

If you still have questions about the settlement, please contact the Hyundai Settlement Administrator at: or by phone at: 833-462-8721 (available Mon – Fri 7:00AM – 5:00PM (PST)).
