Key Engine-Related Recalls Affecting the 2015 Hyundai Sonata

The 2015 Hyundai Sonata has been subject to multiple recalls in the United States and other markets. Many of these are linked to Hyundai’s broader engine defect issues that have affected millions of vehicles worldwide. This section explains the main U.S. National Highway Traffic Safety Administration (NHTSA) engine-related recalls that 2015 Sonata owners should know about.

1. Engine Failure Risk Due to Connecting Rod Bearing Wear

One of the most prominent recalls affecting the 2015 Sonata concerns premature wear of the connecting rod bearings inside the engine. This issue can cause abnormal engine noise, reduced power, engine seizure, or, in severe cases, increase the risk of fire.

The following list outlines the core details of this major recall, including the nature of the defect, symptoms drivers might notice, and the official remedy.

Recall scope: Many 2015 Hyundai Sonata models equipped with 2.0L or 2.4L GDI four-cylinder engines manufactured at Hyundai’s U.S. plant have been included in engine recalls linked to bearing wear.

Underlying problem: Metal debris from the engine manufacturing process could remain in the crankshaft oil passages. Over time, this debris may restrict oil flow to the connecting rod bearings, causing premature wear.

Risks and symptoms: Drivers may notice knocking noises from the engine, reduced power, illumination of the check-engine light or oil pressure warning light, engine stalling, or total engine failure. In extreme cases, a seized engine can lead to a sudden loss of power while driving.

Safety risk: Engine failure during operation can increase the risk of a crash. In some related Hyundai/Kia engine cases, overheating and friction damage have also been linked to an elevated risk of fire, though not every 2015 Sonata engine recall specifically cites fire as the primary risk.

Manufacturer remedy: Hyundai dealers are instructed to inspect the engine, often using a knock-sensor detection system software update to detect early bearing wear. If abnormal bearing wear is detected, the engine is typically replaced at no cost to the owner.

Extended coverage: In connection with broader engine issues, Hyundai has implemented extended warranties or special policy adjustments for many affected engines, offering longer coverage for engine-related failures linked to this defect when owners complete required inspections or software updates.

Owner notification: Hyundai has mailed recall notices to registered owners advising them to bring vehicles to dealers for inspection and repair. Owners can also check recall status using their VIN on Hyundai’s website or via NHTSA’s recall lookup tool.

This recall is central to the 2015 Sonata’s engine reputation: it targets a manufacturing-related defect that can lead to serious engine damage, and it generally requires inspection and, in some cases, full engine replacement to resolve.

2. Electronic Parking Brake and Stalling/Powertrain Concerns (Related Campaigns)

While not always labeled strictly as “engine” recalls, certain campaigns affecting the 2015 Sonata involve systems that can affect drivability or interact with the powertrain. Though they may not directly replace the engine, they are relevant to overall safety and engine operation context.

The following list summarizes some related recalls and campaigns that, although not classic internal-engine defects, are often part of the same broader safety picture for 2015 Sonata owners.

Electronic parking brake software updates: Some 2015 Sonatas were recalled for software errors that could prevent the electronic parking brake warning light from illuminating correctly when a malfunction was present. While this is more of a braking-system issue, it can be included in the same recall history searches owners perform for engine-related problems.

Transmission shift-cable issues: Certain recalls addressed shift-cable or shift-linkage problems that could cause the transmission to not accurately reflect the gear selected by the driver. Though not an engine defect, it can be perceived by owners as a powertrain failure or stall-related issue.

Knock-sensor detection system software (service campaigns): Hyundai has rolled out software campaigns that upgrade the engine control module (ECM) to detect early signs of rod bearing wear using a knock-sensor algorithm. While sometimes classified as a “service campaign” rather than a traditional recall, participation is often critical to extended engine warranty eligibility.

Result for owners: These campaigns aim to reduce the risk of sudden stalling or loss of propulsion due to engine failure by intervening earlier—either through warning lights or pre-emptive engine replacement when abnormal data is detected.

Although these actions are not always categorized purely as “engine recalls,” they form part of the broader safety net Hyundai has deployed to catch and mitigate engine failures in 2015 Sonata models.

Fire Risk Recalls That May Affect 2015 Sonata Owners

Several Hyundai recalls across the mid‑2010s fleet address fire risks that can occur even when the vehicle is parked and turned off. For 2015 Sonata owners, some of these relate not to internal engine failure itself but to components in the engine bay or braking system that can overheat and ignite.

3. ABS Module and Electrical Fire Risk in the Engine Compartment

One notable set of recalls concerns the anti-lock brake system (ABS) module, which is typically housed in the engine compartment and can be exposed to moisture and electrical issues, creating an elevated fire risk.

The list below explains the nature of ABS-related fire-risk recalls that may affect some 2015 Sonata configurations.

Defect description: In certain models, the ABS module could short-circuit internally, often due to moisture intrusion or internal electrical issues.

Fire risk: A short in the ABS module can cause overheating and potentially start a fire in the engine compartment, even when the vehicle is off and parked.

Engine-bay relevance: Because the ABS module is mounted in or near the engine bay, these incidents may be perceived as “engine fires,” even though the root cause is electrical rather than a mechanical engine failure.

Warning signs: The ABS or brake warning light may illuminate, or the driver may notice a burning smell or smoke from the front of the vehicle.

Remedy: Hyundai dealers inspect and, if necessary, replace the ABS module or install additional fusing to prevent overheating. Owners are often advised to park vehicles outside and away from structures until repairs are completed.

These recalls expand the safety picture beyond internal engine wear by addressing fire hazards originating from electrical components in the engine compartment, which are highly relevant to how owners experience “engine-related” safety risks.

4. Fuel Line and Fuel System Issues Near the Engine

In some Hyundai sedans of this era, fuel-system recalls have addressed cracks or leaks in fuel lines or hoses near the engine, which can also create fire hazards. For 2015 Sonatas, applicability depends on specific engine and equipment combinations.

The following list summarizes how fuel-system issues intersect with engine-bay safety for the 2015 Sonata.

Potential defect: Cracking or poor sealing in fuel lines or fuel-feed hoses can lead to fuel leaks in the engine compartment.

Risk: Escaping fuel may come into contact with hot engine components, creating a risk of fire.

Symptoms for drivers: Smell of gasoline around the vehicle, visible fuel leakage under the hood or beneath the car, or difficulty starting the engine.

Manufacturer remedy: Inspection and replacement of affected fuel lines or components at no cost to the owner, if a recall applies to the specific VIN.

Overlap with engine concerns: While not an internal engine defect, a leaking fuel system inside the engine bay is often interpreted by owners as an “engine-related recall” because the danger originates under the hood and can lead to engine-compartment fires.

These fuel-system actions demonstrate that not all 2015 Sonata “engine recalls” involve pistons and bearings; some concern the fuel delivery system and its interaction with hot engine components.

How to Check Whether Your 2015 Sonata Is Under an Engine Recall

Because recall coverage depends on build date, engine type, manufacturing plant, and previous repair history, not all 2015 Sonatas are affected by every recall. The only reliable way to know your status is to check using your vehicle’s unique identification number (VIN).

The following list outlines practical steps 2015 Hyundai Sonata owners should take to verify recall status and obtain free repairs where applicable.

Locate your VIN: Your 17‑digit VIN is usually found on the driver’s side dashboard near the windshield, on the driver’s door jamb label, and on your registration or insurance documents.

Use the NHTSA recall lookup: Visit the National Highway Traffic Safety Administration website at nhtsa.gov/recalls and enter your VIN. The tool will show all safety recalls that have not yet been completed on your vehicle in the United States.

Check Hyundai’s official site: Go to Hyundai’s recall page (often branded as “Hyundai Recall” or “Recall Information”) and enter your VIN for details, including service campaigns and, in some cases, extended warranty programs that may not appear as formal NHTSA recalls.

Call a Hyundai dealer: Provide your VIN to a Hyundai dealership service department and ask them to confirm open recalls and service campaigns, particularly engine and knock-sensor software updates.

Request a service history printout: Dealers can often show which recalls or engine campaigns have already been completed on your vehicle, which is especially important if you are not the original owner.

Schedule repairs promptly: If an open safety recall is listed, the repair should be performed free of charge. For engine-related recalls, it’s wise to schedule as soon as possible because parts (like replacement engines) can sometimes be in high demand.

Keep documentation: Save all service records, recall letters, and invoices. Documentation can help if you experience future engine problems or need to pursue goodwill coverage or extended warranty claims.

Following these steps ensures that you know exactly which engine or engine-bay recalls apply to your specific 2015 Sonata and that you can take advantage of free safety repairs and extended protections where available.

What Owners Should Watch For Day-to-Day

Even if all recalls are completed, 2015 Sonata owners should remain alert for symptoms of engine distress or engine-compartment issues. Early detection can prevent breakdowns and may support warranty or recall-related repairs.

Warning Signs of Possible Engine or Engine-Bay Trouble

There are several noises, smells, and dashboard indicators that may suggest a developing issue in a 2015 Sonata’s engine or related systems.

Unusual engine noises: Knocking, ticking, or metallic tapping sounds that increase with engine speed can indicate bearing wear or other internal damage.

Dashboard warning lights: Check-engine, oil pressure, ABS, or brake warning lights illuminating and staying on should never be ignored.

Loss of power or stalling: Hesitation, reduced acceleration, or the engine shutting off unexpectedly while driving are red-flag symptoms.

Smoke or burning smells: Smoke from the hood area, burning smells, or the scent of melting plastic or wiring can point to an electrical or fluid leak issue in the engine bay.

Fuel odor: Persistent smell of gasoline around the vehicle or in the cabin may indicate a fuel-system leak under the hood or near the tank.

Overheating indicators: Rising temperature gauge, coolant loss, or steam from the engine compartment can signal cooling-system failure, which, if ignored, can quickly damage the engine.

Recognizing these signs early and seeking professional inspection can limit damage, reduce safety risks, and improve the likelihood that Hyundai or a dealer will assist under a recall or warranty policy.

Why So Many Hyundai Engine Recalls Affected the 2015 Model Year

The 2015 Sonata sits within a broader wave of Hyundai and Kia engine issues that have affected numerous model years and platforms. Understanding this background helps explain why multiple engine-related recalls and campaigns cover this particular year.

The following list summarizes the broader context behind Hyundai’s engine recall campaigns and how the 2015 Sonata fits into that story.

Shared engine families: Many 2015 Sonatas use 2.0L and 2.4L Theta II GDI engines or related engine families, which are shared across multiple Hyundai and Kia models and have been at the center of large-scale recalls.

Manufacturing debris problem: Investigations found that some engines left the factory with machining debris in oil passages, leading to bearing oil starvation and premature wear.

Escalating complaints: Reports of knocking engines, stalling, and fires prompted NHTSA investigations and class-action litigation, pushing Hyundai and Kia to expand recalls, extend warranties, and implement new detection software.

Regulatory and legal pressure: U.S. safety regulators and consumer lawsuits contributed to wider recall coverage and stricter reporting and repair obligations for Hyundai and Kia.

Ongoing policy changes: In response, Hyundai has increasingly used proactive software updates (like knock-sensor algorithms) and broader goodwill repairs to contain risk and rebuild consumer trust.

This context explains why owners of a 2015 Sonata often find not just a single engine recall but a patchwork of recalls, service campaigns, and extended warranty programs that together address the underlying defect and its consequences.
