Hyundai KIA 2.4L Engine Specs, Problems & Reliability

Hyundai KIA 2.4L Engine

Here in this post, I have gathered information about the Hyundai KIA 2.4L Engine from its official website, including its specifications, Problems, and Reliability.

We believe in providing reliable information to our readers, therefore we prefer to obtain information on the Hyundai KIA 2.4L Engine from authentic sources.

This article, which has been updated, has all the information you require about the Hyundai KIA 2.4L Engine.

Hyundai KIA 2.4L Engine

Hyundai’s 2.4-liter (G4KC, G4KE, G4KG, and G4KJ) motor is a member of the Theta/Theta II engine family.

Depending on the generation and the car it powers, this gasoline engine has four cylinders and either multi-point or direct injection.

This engine is also shared by Hyundai and the KIA brand.

Because of the larger engine displacement and heavier internal loads, the 2.4L is nearly identical to the 2.0L variant of the same Theta series, with a few minor modifications.

Engine Hyundai 2.4 Theta
Displacement 2,359cc (144 cu in)
Configuration Inline-4
Aspiration Natural
Block/Head Material Aluminium
Valvetrain DOHC, 16 valve
Compression Ratio 10.3: 1 thru 11.3: 1
Bore x Stroke 88mm x 97mm
Horsepower 163-200 hp
Torque (lb-ft) 161-184 lb-ft

Hyundai KIA 2.4L Engine (Theta MFI/GDI) Problems 

2.4L Theta II MPI & GDI Engine Failures

We also covered the subject of engine failure for the 2.0T Theta engine.

Unfortunately, engine failure is a common problem for vehicles with 2.4-litre engines, which is indicative of a broader set of problems. All model years and variants may be affected.

Engine failure is most typical for the 2011–2014 Hyundai Sonata and the 2013–2014 Santa Fe. Some Kia cars with 2.4 Theta II engines are also susceptible to issues. The Optima, the Sorento, and the Sportage are all included.

Considering how often it has already been discussed, we will refrain from going over the same ground.

Because of the serious safety issues posed by the vehicles’ engines, both Kia and Hyundai were hit with significant fines.

Because of the recalls or because they were still under warranty, many engines were changed.

Problems with the rod bearings are usually to blame when an engine breaks down.

Due to inadequate oil flow, the 2.4L Theta II’s rod bearings quickly wear out if debris from production is not removed.

In the end, they seize up and stop working altogether, rendering the engine useless.

As of 2021, we don’t see this as much of a concern for the Hyundai 2.4-liter engine. Nevertheless, it’s important to remember that fixing a broken engine might be very expensive.

Hyundai 2.4L Oil Consumption Issues

The prior topic is occasionally related to the one we’re discussing now: oil usage in excess.

Oil consumption that is abnormally high but not because of mechanical issues with the engine is being disregarded.

There have been numerous reports of Hyundai 2.4 Theta engines consuming excessive amounts of oil despite the absence of any other discernible issues.

These problems also affect the 2.4-litre inline four-cylinder engine.

Oil gets used up in engines occasionally. This is true of any gasoline-powered internal combustion engine.

In many cases, blow-by through the piston rings causes some oil loss. Since metals expand when heated, the spaces between the piston rings are smaller in a cold engine.

In other words, the Hyundai 2.4L engine’s tendency for excessive oil consumption is primarily a cold-weather phenomenon.

Hyundai KIA 2.4L Engine Reliability

How dependable is Hyundai’s 2.4-liter Theta II MPI and GDI motor? We rate the reliability of this engine as around average.

Dependability is hindered by the frequent occurrence of catastrophic engine breakdowns.

However, Hyundai and Kia covered several 2.4L engine problems through recalls or the standard warranty.

Newer replacement engines don’t appear to be experiencing the same frequency of problems, so this is hopefully a permanent fix.

The Hyundai 2.4 Theta II GDI has a problem with carbon buildup. This is a minor drawback to an otherwise fantastic upgrade that makes use of direct injection.

Hyundai 2.4 Theta engines frequently have high oil consumption and oil leakage.

Hyundai KIA 2.4L Engine FAQ

Is the 2.4 L Hyundai engine good?

To make matters worse, the 2.4L Theta II engine has a reputation for being unreliable.

Some concerns about dependability might be allayed by a solid warranty and periodic recalls.

As for MPI and GDI stability in 2.4, we’ll go back to that at the end of the piece.

What does 2.4 GDI mean?

The 2.4-liter Theta II GDI engine uses gasoline direct injection (GDI) technology, which makes it run more efficiently while using less fuel, making less pollution, and giving better throttle response and more power.

Is a 4-cylinder 2.4 L engine good?

Is it a smart idea to get a 2.4-litre engine? The 2.4 is widely regarded as a reliable engine free of serious faults, with well-designed head gaskets and sufficient oil sealing.

Is a 2.4 L engine economical?

The 2.4L 4×4 model has a fuel economy of approximately 9.3L/100km, while the 2.0L 2wd model has a fuel economy of 7.6L/100km.

It will have a somewhat higher operating cost per gallon of gas. Service parts for a 2.4-litre engine should cost about the same as those for a 2.0-litre one, as the only major mechanical differences are the rear differential and prop shaft.
