Hyundai Sonata Plug-In Hybrid Battery Repair Settlement
By the Class Action Buddy Editorial Team · Last reviewed November 5, 2026
There is a receipt-hunt you do not have to do here. The number of days your Sonata sat waiting for a high-voltage battery comes out of Hyundai's own service records, not out of your filing cabinet. You sign the claim form under penalty of perjury and the day count is taken from the repair history logged against your vehicle.
Then the arithmetic runs backwards from what you would expect. The rate starts at $10 for every day in the battery repair period, and it climbs to as much as $15 a day if the total claimed across the whole class comes in under $250,000. In most settlements a crowd of claimants shrinks everyone's share. In this one a quiet turnout raises the rate.
One date is worth putting in your phone. The claim deadline is December 28, 2026, but the final approval hearing is December 21, a week earlier. The calendar runs in the wrong order, which means a late claim arrives after the judge has already finished with the case.
It covers 2016 to 2019 Sonata Plug-In Hybrids whose warranty battery repair could not be completed inside 60 days. For most people that wait fell between late 2021 and the summer of 2023.

Take our 60-second eligibility quiz to find every settlement you qualify for — including this one.
Who Is Eligible?
You may be eligible to file a claim if you:
- You owned or leased a 2016-2019 model year Hyundai Sonata Plug-In Hybrid at the time it needed the battery repair.
- The high-voltage battery needed repair or replacement during the express warranty period, parts were not available, and the car could not be repaired for a minimum of 60 days.
- The 60-day wait is the test, not the battery failure. A battery replaced promptly under warranty is not a claim. The settlement is about being without the car.
- For most class members the wait fell between late 2021 and the summer of 2023, which is the window the parties identify in the notice.
- Not covered: claims for personal injury, wrongful death or damage to other property. This settlement is about days out of service only.
How Much Can You Get?
$10 for every day in the battery repair period, and the rate can rise to a maximum of $15 a day if total claimed payments across the class come in under $250,000.
That runs opposite to most settlements. Where a pro rata fund shrinks each share as more people file, here a low overall turnout is what triggers the higher rate. Filing does not dilute anyone.
Hyundai’s records supply the day count. The payment is based on the days without a repair logged against your vehicle in Hyundai’s own service history, so there is no invoice to hunt down. You sign the claim form under penalty of perjury; further documentation is only needed where ownership during the repair is in doubt or disputed.
Coming out of the fund: class counsel will seek fees and expenses not exceeding $375,000, plus $7,500 for each class representative.

Frequently Asked Questions
What is the deadline to file a claim for the Hyundai Sonata Plug-In Hybrid Battery Repair Settlement?
The current deadline to file a claim is Dec 28, 2026. Claims sent by mail must be postmarked by this date, so allow about a week for delivery if you are not filing online.
Do I need proof of purchase for the Hyundai Sonata Plug-In Hybrid Battery Repair Settlement?
No proof of purchase is required — you can typically file based on a sworn statement, without receipts, photos, or product packaging. You also do not need a Claimant ID or PIN to file.
How do I file a claim for the Hyundai Sonata Plug-In Hybrid Battery Repair Settlement?
File directly with the settlement administrator, using the official claim form linked on this page. Class Action Buddy does not support this settlement in the app, so the administrator’s own claim process is the route. You do not need a Claimant ID or PIN to file.
Do I need the repair invoice or service records?
No. The day count comes from the repair history logged against your vehicle in Hyundai’s own records, not from paperwork you produce. You sign the claim form under penalty of perjury, and extra documentation is requested only if who owned or leased the car during the repair is unclear or disputed.
Does my payment shrink if lots of people claim?
Not in the usual way. The base rate is $10 per day down. It can increase to as much as $15 per day if total claimed payments across the class stay under $250,000, so heavy participation means the rate stays at $10 rather than everyone being diluted below it.
My battery failed but was replaced in three weeks.
Then you are outside this class. The definition requires that parts were unavailable and the car could not be repaired for a minimum of 60 days. The settlement compensates the wait rather than the failure.
I sold the car years ago. Does that matter?
What matters is that you owned or leased it during the time it was awaiting the battery repair. Selling it afterwards does not remove the claim, though you may be asked to establish ownership for that period.
