A class settlement against Hyundai Motor America (“HMA”) that had alleged that certain 2011 – 2022 model year Hyundai vehicles that were not equipped with an engine immobilizer (called the “Class Vehicles”) contain design flaws, including the failure to manufacture the Class Vehicles with an anti-theft device called an engine immobilizer, that make them susceptible to theft and damage. Class Vehicles manufactured without an engine immobilizer have traditional “turn-key-to-start” ignition systems.

At what mileage does the electrical typically fail?

A quarter of owners report trouble before 47,549; a quarter make it past 70,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
