Hyundai Engine Warranty Extension: Everything You Need to Know

Dealing with engine problems can be a major headache and expense. If you own a Hyundai, you might be eligible for significant warranty protection that goes well beyond the standard coverage. Hyundai has implemented comprehensive engine warranty extension programs that could save you thousands in repair costs and provide peace of mind for years to come. Let’s dive into what these programs offer, which vehicles qualify, and how you can make sure you’re protected.

What Is the Hyundai Engine Warranty Extension?

Hyundai’s engine warranty extension programs provide coverage for up to 15 years or 150,000 miles from the original purchase date of your vehicle. That’s a massive increase from the standard 10-year/100,000-mile powertrain warranty that Hyundai typically offers.

These extensions were created in response to identified defects in certain engine models that could lead to failures, fires, and other safety issues. The coverage specifically addresses engine damage or malfunction caused by connecting rod bearing failure, which has been a notable problem in several Hyundai models.

Which Hyundai Models Qualify for Extended Engine Warranty?

The extended warranty coverage (known as TXXM) applies to numerous Hyundai models with specific engines. Here’s a breakdown of eligible vehicles:

Additionally, there’s a separate extension program (TXX8) specifically for Santa Fe and Santa Fe XL models from 2013-2019 that are equipped with 3.3L Lambda II GDI engines. These vehicles may experience abnormal engine noise or damage and are covered for the same 15 years/150,000 miles.

The Critical Knock Sensor Detection System Requirement

Here’s something crucial: to qualify for this extended warranty coverage, most eligible vehicles must have the Knock Sensor Detection System (KSDS) installed. This isn’t just a technicality—it’s a key requirement that could make or break your warranty claim.

What Is KSDS and Why Does It Matter?

The Knock Sensor Detection System is specialized software that monitors your engine for abnormal vibrations that might indicate potential connecting rod bearing wear. It’s designed to detect problems before they cause catastrophic engine failure.

When the system detects concerning vibrations:

• The malfunction indicator lamp will blink continuously
• You’ll hear an audible chime
• The vehicle enters a temporary engine protection mode with reduced power
• You’ll maintain full control of brakes, steering, and safety systems

This early warning system can potentially save your engine from complete failure and help you get service before a minor issue becomes a major problem.

How to Get KSDS Installed

The KSDS update is available at no cost through Service Campaign 966 or 982 at authorized Hyundai dealerships. If your vehicle was previously recalled under Recalls 198 and 209, you’re exempt from this requirement—but it’s still recommended to get the update for added protection.

What the Extended Warranty Covers

The hyundai engine warranty extension specifically covers:

• Engine repairs and/or replacement where engine damage is caused by connecting rod bearing failure
• All parts and labor costs associated with covered repairs
• Rental car reimbursement during repair periods
• Towing to the nearest Hyundai dealership if your vehicle breaks down

It’s important to note that routine maintenance items like oil changes aren’t covered, and you’ll need to maintain your vehicle according to Hyundai’s recommended schedule to keep the warranty valid.

Recent Class Action Settlements Expanding Coverage

Hyundai’s warranty extensions have been bolstered by recent class action settlements that provide additional benefits to affected owners.

Engine II Settlement (2024)

In April 2024, Hyundai received final approval for a comprehensive settlement covering over 2.1 million additional vehicles with Theta II MPI, Gamma GDI, and Nu GDI engines. The settlement benefits include:

• The 15-year/150,000-mile extended warranty for connecting rod bearing failure
• Reimbursement for qualifying repairs at both dealerships and third-party shops
• Transportation and towing reimbursements
• Goodwill payments for repair delays
• Compensation for vehicles sold after experiencing failures
• Rebate programs for replacement vehicle purchases

This settlement builds upon a previous $1.3 billion settlement in 2021 that covered nearly 4 million vehicles with Theta II GDI engine defects.

How to Check If Your Vehicle Qualifies

Wondering if your Hyundai is eligible for the extended engine warranty? Here’s how to find out:

1. Visit HyundaiUSA.com/Campaign and enter your VIN (Vehicle Identification Number)
2. See if Service Campaign 966 or 982 is listed as open for your vehicle
3. Alternatively, use the VIN validation tools at autoservice.hyundaiusa.com

Your VIN can be found on your vehicle registration, insurance card, or on a plate visible through the windshield on the driver’s side dashboard.

Steps to Take If Your Vehicle Qualifies

If you confirm that your vehicle is eligible for the hyundai engine warranty extension, here’s what you should do:

1. Schedule an appointment at your nearest Hyundai dealership to have the KSDS installed (if required)
2. The installation is free of charge and typically takes less than an hour
3. Once completed, your vehicle will be officially enrolled in the extended warranty program
4. Keep all maintenance records, particularly oil changes which should be done every 7,500 miles or 12 months

Warning Signs of Engine Problems

Even with the warranty extension in place, it’s important to know the warning signs of potential engine issues so you can address them promptly:

• Unusual knocking or ticking sounds from the engine
• Check engine light illumination
• Sudden loss of power while driving
• Excessive oil consumption
• Engine hesitation or stalling
• Blue or white smoke from the exhaust

If you experience any of these symptoms, contact your Hyundai dealer immediately for inspection. Under the warranty extension, dealers will provide free service loaner vehicles or rental car reimbursement during repairs.

Maintaining Your Vehicle to Preserve Warranty Coverage

To ensure your extended warranty remains valid, you’ll need to follow some basic maintenance guidelines:

• Follow Hyundai’s recommended maintenance schedule
• Keep detailed records of all maintenance, especially oil changes
• Use the recommended grade and type of oil
• Have service performed at authorized dealers or keep thorough documentation if using independent shops
• Address any warning signs or recall notices promptly

Regular oil changes are particularly important, as insufficient oil can accelerate engine wear and potentially void warranty coverage.

Transferability of the Extended Warranty

Good news if you’re thinking of selling your Hyundai: the extended warranty coverage transfers to subsequent owners. This can be a significant selling point if you decide to part with your vehicle before the warranty expires.

The only exceptions are for commercial entities and salvaged vehicles, which are ineligible for continued coverage under the extended warranty program.

What to Do If You Experience Engine Failure

If your engine fails and you believe it should be covered under the hyundai engine warranty extension:

1. Have your vehicle towed to an authorized Hyundai dealership
2. Inform the service department that your vehicle should be covered under the extended engine warranty program
3. Provide maintenance records, especially proof of regular oil changes
4. Request a loaner vehicle or rental car reimbursement while repairs are being completed
5. Get any warranty coverage decisions in writing

If your claim is denied and you believe it should be covered, you can escalate the issue to Hyundai Customer Care at 1-800-633-5151.

The Benefits of Having KSDS Installed

Even if your engine seems fine now, having the Knock Sensor Detection System installed provides significant benefits:

• Early detection of potential engine issues before catastrophic failure
• Potential prevention of being stranded due to sudden engine failure
• Protection mode that allows you to safely drive to a service location
• Qualification for the extended warranty coverage
• Peace of mind during the extended ownership period

The system essentially acts as an early warning system that could save you from being stranded on the side of the road or facing a completely failed engine.

Real-World Experience with the Extended Warranty

Many Hyundai owners have shared positive experiences with the warranty extension program. For example, one Santa Fe owner reported that their engine failure was fully covered under the extended warranty, saving them thousands in repair costs.

While experiences can vary, the comprehensive nature of the warranty extension has provided significant relief for many owners who would otherwise face substantial repair bills.

Beyond Engine Coverage: Understanding Hyundai’s Full Warranty

While the engine warranty extension is impressive, it’s worth understanding Hyundai’s complete warranty package, often marketed as “America’s Best Warranty”:

• New Vehicle Limited Warranty: 5 years/60,000 miles
• Powertrain Limited Warranty: 10 years/100,000 miles (original owner only)
• Anti-Perforation Warranty: 7 years/unlimited miles
• Replacement Parts Warranty: 1 year/12,000 miles
• 24/7 Roadside Assistance: 5 years/unlimited miles

The engine warranty extension effectively extends the powertrain coverage specifically for engine failures related to connecting rod bearing issues.

If you own an eligible Hyundai, taking advantage of this warranty extension by having the KSDS installed (if required) is a no-brainer. The peace of mind that comes with knowing you’re protected against potentially expensive engine repairs for up to 15 years or 150,000 miles is invaluable.

Remember to maintain your vehicle according to Hyundai’s recommendations, keep detailed service records, and address any warning signs promptly to ensure your warranty remains valid throughout its extended duration.
