The Hyundai Sonata is a popular midsize car known for its reliability and fuel efficiency. It also has a generous engine warranty covering most of the engine’s major components. We’ll look at what that warranty covers and some of the most common questions people have about it.
Hyundai Sonata Engine Warranty Coverage
The Hyundai Sonata comes standard with a 10-Year / 100,000-Mile Powertrain Limited Warranty. This warranty covers repairing or replacing powertrain components like certain engine and transmission/transaxle components. However, these components must be originally manufactured or installed by Hyundai, and they must be defective in terms of material or factory workmanship in order to qualify for warranty coverage.
Hyundai extended the warranty to the current 10-year / 100,000-Mile warranty following the class-action lawsuit resulting from issues with the Hyundai’s Theta II 2.0-liter turbo or 2.4-liter naturally aspirated engine. If you own a 2011-2019 Hyundai Sonata, you may be able to get your Theta II engine replaced free of charge.
Below we will cover the other components of the Hyundai factory warranty. It can be difficult to make odds or ends out of all of these warranty names so, if you would like a full breakdown of how car warranties work and all of these terms, check out our The Ultimate Guide to Car Warranties.
Additional Coverage Included with the Hyundai Warranty
In addition to the Powertrain Limited Warranty, all new Hyundai Sonatas come with a 5-Year / 60,000-Mile New Vehicle Limited Warranty. Hyundai will repair or replace any OEM (Original Equipment Manufacturer) part that is under warranty for material or factory defects, as long as the vehicle usage has been “normal” and the vehicle’s maintenance is up-to-date. This covers the audio system, paint, battery, AC, and basic parts like wiper blades and fuses.
There’s also a 7-Year / Unlimited Miles Anti-Perforation Warranty that covers against rust-through perforation of the vehicle body. And finally, there’s a 12-Month / 12,000-Mile Replacement Parts and Accessories Limited Warranty that covers certain replacement parts and accessories.
24-Hour Roadside Assistance
Hyundai also gives 24-hour roadside assistance for up to five years with unlimited miles. This policy takes effect once the vehicle either gets delivered to the first customer or is put into use, whichever happens sooner.
Electric Battery and Hybrid System Components
Hyundai covers batteries and system components for all hybrid, plug-in hybrid, and all-electric vehicles with a 10-year/100,000-mile warranty. All electric car batteries will degrade over time, but Hyundais are guaranteed not to fall below 70 percent capacity during the warranty period. If it does, the battery will be replaced under warranty.
Emissions Coverage on the Hyundai Sonata
All new Hyundai Sonatas come with an 8-Year / 80,000-Mile Federal Emission Defect and Performance Warranty, which covers the repair or replacement of certain emission control parts and systems that are original to the vehicle and under warranty. Covered elements may include catalytic converters, electronic control modules, and fuel injectors.
To be eligible for this warranty, you must have the emission-related repairs performed by an authorized Hyundai dealer using genuine Hyundai replacement parts. You will also need to keep up with all required maintenance as specified in your Sonata’s Owner’s Manual.
