What Is the Recall on the 2016 Hyundai Tucson Engine?

The 2016 Hyundai Tucson has been subject to several engine-related recalls and service campaigns, most notably for engine stalling, potential engine damage from debris or oil starvation, and, in some cases, fire risk. These issues primarily involve 2.0L and 1.6L engines built within specific date ranges, and remedies typically include software updates, inspections, and in serious cases, engine replacement at no cost to the owner.

Background: Why the 2016 Hyundai Tucson Engine Came Under Scrutiny

The 2016 Hyundai Tucson was part of a broader wave of engine-related problems affecting Hyundai and Kia vehicles in the mid‑2010s, leading to multiple National Highway Traffic Safety Administration (NHTSA) investigations and formal recalls. Owners reported issues ranging from sudden loss of power and stalling to knocking noises and, in rare cases, fires, prompting safety actions and extended warranties.

Key Engine-Related Recalls Affecting the 2016 Hyundai Tucson

The 2016 Tucson is covered by a mix of official safety recalls and customer service campaigns, depending on engine type, production range, and market (U.S., Canada, etc.). While the specifics vary, the central theme is the risk of engine damage that could lead to stalling, loss of power, or fire.

Recall for 2.0L GDI Engine: Connecting Rod Bearing & Fire Risk

One of the most significant actions affecting some 2016 Tucsons equipped with 2.0L gasoline direct injection (GDI) engines is a recall and related campaigns linked to potential connecting rod bearing wear. In affected engines, improper machining or contamination in the engine could cause premature bearing wear. As the bearing deteriorates, the engine may start to knock, lose power, stall, or, in extreme cases, seize and possibly catch fire.

This issue is closely related to Hyundai’s broader “Theta II” engine problems, though not every 2016 Tucson uses a Theta II. Hyundai’s response has typically involved diagnosing any abnormal engine noise, applying software that monitors for bearing failure (Knock Sensor Detection System, or KSDS), and, where damage is detected, replacing the engine.

Engine Stalling and Hesitation in 1.6L Turbo Models

Some 2016 Hyundai Tucson models equipped with the 1.6L turbocharged engine and dual-clutch transmission (DCT) have been covered by recalls and service campaigns due to drivability issues such as hesitation, delayed acceleration, or stalling from a stop. Although primarily transmission-control related, these problems are often perceived by owners as “engine” issues because they result in sudden loss of power or difficulty moving from a standstill.

Software updates to the transmission control module and engine control unit were released to address this behavior, and in many cases Hyundai notified owners and updated vehicles free of charge. While not a catastrophic engine defect, it directly affects how the engine delivers power and can raise safety concerns in traffic.

Fuel and Oil-Related Concerns: Indirect Engine Risks

Separate from the core bearing-wear issues, there have been campaigns and technical service bulletins (TSBs) addressing leaks or component failures that can indirectly jeopardize engine health. For example, issues with oil leaks, fuel system components, or turbocharger oil supply can, if left uncorrected, lead to oil starvation and subsequent engine damage.

These types of issues do not always rise to the level of a formal NHTSA safety recall, but Hyundai dealers may perform inspections, repairs, or part replacements under extended warranties or TSB-directed service, especially if problems are caught early.

How the Recalls Typically Work: Diagnosis, Software, and Engine Replacement

For most affected owners, the recall process involves notification, inspection at a Hyundai dealership, and in some cases engine monitoring software or complete engine replacement. Understanding the typical path helps clarify what “engine recall” actually means in practice.

Knock Sensor Detection System (KSDS) and Monitoring

For vehicles at risk of connecting rod bearing wear, Hyundai has deployed the Knock Sensor Detection System via software updates. This system continuously listens for specific vibration and knocking patterns that indicate bearing damage. If the KSDS detects such patterns, it triggers a warning and logs diagnostic codes that prompt further inspection at the dealer.

If bearing damage is confirmed, Hyundai’s remedy usually includes replacing the short block (the main engine assembly) at no cost to the owner, provided the vehicle falls within the recall or extended warranty parameters.

Extended Warranties and Goodwill Repairs

As engine issues became more widely recognized, Hyundai extended warranties on certain affected engines to provide longer coverage against defects related to internal engine wear. For some owners outside the strict recall production range but exhibiting similar symptoms, Hyundai has at times offered goodwill repairs or partial coverage, depending on mileage, maintenance records, and dealer advocacy.

This means that even if a specific Tucson is not in a formal recall build range, owners with engine failure symptoms may still have some routes to relief, particularly if they have followed the recommended maintenance schedule and can document oil changes.

How to Check Whether Your 2016 Tucson Is Affected

Because not every 2016 Hyundai Tucson is included in the same campaigns, confirming your individual vehicle’s status is essential. Engine type, build date, and VIN (Vehicle Identification Number) determine which recalls or service campaigns apply.

The following steps can help clarify recall status and next actions for owners:

• Use the NHTSA website (in the U.S.) or your country’s safety agency to run a VIN search for open recalls.
• Check Hyundai’s official recall lookup tool using your VIN for brand-specific campaigns and extended coverage.
• Contact a Hyundai dealership service department with your VIN and ask for a printout of all open recalls, campaigns, and TSBs.
• Review any mailed recall notices or emails from Hyundai, as some campaigns are time-sensitive or phased by region.
• Keep maintenance records handy, as they can affect warranty and goodwill repair decisions.

Following these steps ensures you know exactly which engine-related actions apply to your Tucson and allows you to schedule the needed inspections or repairs promptly.

Typical Symptoms Owners Report Before Recall Repairs

Drivers often notice signs of trouble before a recall repair or service campaign is carried out. Recognizing these symptoms early can prevent more serious damage and make it easier to secure warranty coverage.

Common engine-related symptoms on the 2016 Tucson include:

• Knocking, ticking, or tapping noises from the engine, especially under acceleration.
• Reduced power, sluggish acceleration, or hesitation when pulling away from a stop.
• Illuminated “Check Engine” light or other warning lights on the instrument cluster.
• Engine stalling or sudden loss of power while driving or idling.
• Excessive oil consumption, oil smell, or visible smoke from the exhaust.

If any of these symptoms appear, owners are generally advised to avoid hard driving, schedule a dealer inspection as soon as possible, and mention any pending recalls or campaigns so the service team can investigate under the appropriate programs.

What Owners Should Do Now

For current or prospective owners of a 2016 Hyundai Tucson, treating the engine recall landscape as part of routine due diligence is important. Even if the vehicle has already undergone recall work, verifying that all campaigns and software updates have been completed adds a layer of security and can prevent repeated failures.

Practical steps for owners and buyers include:

• Run a VIN check through NHTSA and Hyundai’s official recall website before purchase or as part of regular maintenance planning.
• Ask the seller or dealer for service records confirming recall repairs, KSDS installation, and any engine replacements.
• Maintain regular oil changes with the correct specification oil and keep receipts or digital logs.
• Address unusual noises or drivability issues immediately rather than continuing to drive until failure.
• Discuss extended warranty options or existing extensions with Hyundai or the dealer, especially for higher‑mileage 2016 models.

By taking these measures, owners can reduce the likelihood of unexpected engine failure and maximize the support available from Hyundai if problems arise.

Summary

The 2016 Hyundai Tucson has been affected by several engine-related recalls and service campaigns, principally concerning premature internal engine wear, stalling, and in rare cases fire risk, particularly in certain 2.0L and 1.6L models built within defined ranges. Remedies have included software updates like the Knock Sensor Detection System, inspections, and in confirmed failure cases, engine replacement at no cost to the owner. Because not every 2016 Tucson is covered in the same way, the only reliable method to determine eligibility is to run a VIN check through NHTSA and Hyundai’s official recall tools and to coordinate with a Hyundai dealer for inspection and any needed repairs.
