What happened
This lawsuit, Kline et al. v. Hyundai Motor America, Inc., claims that Hyundai did not honor the high-voltage battery warranty on certain 2016 to 2019 Hyundai Sonata Plug-In Hybrids when their batteries failed, and that Hyundai could not repair or replace the batteries for extended periods, so owners lost the full use of their vehicles. The case is pending in the United States District Court for the District of Maryland before United States Magistrate Judge Gina L. Simms.
Hyundai denies that it did anything wrong and says repair delays were caused by factors outside its control, such as COVID-19 supply chain issues and third-party supplier delays. The Court has not decided who is right. The parties agreed to settle to avoid the costs and risks of continued litigation. The settlement does not cover personal injury, wrongful death, or damage to other property.
How to file a claim
-
1. Confirm you are eligible
You must have owned or leased a 2016 to 2019 Hyundai Sonata Plug-In Hybrid whose high-voltage battery needed a warranty repair or replacement that could not be completed within 60 days because parts were unavailable.

2. Understand the Days Down Payment
The payment equals the number of days your vehicle waited for a battery repair, based on Hyundai's records of days without a logged repair, multiplied by $10 per day.

Where the money is going
This is a claims-made settlement. Hyundai pays each approved claim using the Days Down Payment formula of $10 per day, which may rise to $15 per day if total claimed payments are under $250,000. The official notice does not state a total cap or whether fees and administration costs are paid separately from class member payments.
Fee, expense, and service award amounts are requests subject to Court approval at the Final Approval Hearing, and the Court may award less. Individual payment amounts depend on the number of days your vehicle waited for repair according to Hyundai's records.
Common questions
How much money will I receive?
Your payment equals the number of days your vehicle waited for a high-voltage battery repair, based on Hyundai's records, multiplied by $10 per day. If total claimed payments by class members are less than $250,000, the rate may increase to $15 per day. Amounts are not guaranteed until the Court grants final approval.
Do I need to submit proof of purchase?
You must submit a Claim Form signed under penalty of perjury. The number of days is based on Hyundai's records. If your ownership of the vehicle during the battery repair period is in doubt or disputed, you may need to provide additional proof of ownership.
What if I didn’t receive a notice?
If you believe you fit the class definition but did not receive a notice, get more information from the settlement website directly at HVBatteryRepairSettlement.com or call the Settlement Administrator at 1-866-964-4271.
Does staying in the class affect my right to sue later?
Yes. Unless you excluded yourself by October 29, 2026, you are bound by the settlement and release claims related to the battery repair and the claims asserted or that could have been asserted in the lawsuit, whether or not you file a claim. The release does not cover personal injury, property damage, or subrogation claims. The full release is in the Settlement Agreement on the settlement website.
When will payments be sent out?
The Final Approval Hearing is scheduled for December 21, 2026. Payments are made about 60 days after final approval and after any appeals are resolved. Check the settlement website for updates.
