Welcome to the Hyundai Engine II Class Action Settlement Website
A class action Settlement has been proposed in a lawsuit alleging that certain Hyundai vehicles (called the “Class Vehicles” and listed below) have a defect that can cause engine seizure, stalling, engine failure, and possibly engine fire, and that some owners and lessees have been improperly denied repairs under the vehicle’s warranty. Hyundai has not been found liable for any claims alleged in the lawsuit, and the parties have instead reached a voluntary settlement in order to avoid lengthy litigation and to provide relief to Class Members.
You may be eligible for benefits of the class action Settlement if you owned or leased a Class Vehicle, which are certain vehicle models equipped with the corresponding genuine multi-port fuel injection (“MPI”) or gasoline direct injection (“GDI”) engine below:
| Model Year | Model | Engine |
| 2011–2015 | Sonata Hybrid (HEV) | Theta II 2.4-liter MPI Hybrid |
| 2016–2019 | Sonata Hybrid/Plug-In Hybrid (HEV/PHEV) | Nu 2.0-liter GDI Hybrid |
| 2010–2012 | Santa Fe | Theta II 2.4-liter MPI |
| 2010–2013 | Tucson | Theta II 2.4-liter MPI |
| 2014–2021 | Tucson | Nu 2.0-liter GDI |
| 2014 | Elantra Coupe | Nu 2.0-liter GDI |
| 2014–2016 | Elantra | Nu 2.0-liter GDI |
| 2014–2020 | Elantra GT | Nu 2.0-liter GDI |
| 2012–2017 | Veloster | Gamma 1.6-liter GDI |
Under the proposed Settlement, and subject to satisfying the proof requirements, Hyundai will provide financial and other benefits for certain qualifying engine-related repairs and/or engine failures or engine fires. The Settlement extends the Powertrain Limited Warranty to 15 years or 150,000 odometer miles from the date of the vehicle’s original retail delivery, whichever comes first, for damage to the engine short block or long block assembly caused by connecting rod bearing failure (the “Extended Warranty”). In order to obtain the Extended Warranty, you must have completed the Knock Sensor Detection System (“KSDS”) update at a Hyundai dealership prior to any covered engine failure. Class Vehicles subject to Hyundai Recall Numbers 198 and 209 (NHTSA Recall Numbers 20V746 and 21V727) are exempt from this requirement. Generally, to obtain non-Extended Warranty benefits, you need to first complete the free KSDS update at a Hyundai dealership by November 4, 2023.
The deadline to submit a claim for most benefits is December 7, 2023. Any extension of this date will be posted on the scheduling and key dates section of this website. Please see the complete Class Settlement Notice for more information regarding the Settlement.
