All You Need To Know About The Hyundai Theta Engine Piston Settlement

On May 10, 2021, a Judge granted final approval to the Hyundai Theta Settlement. The settlement was to benefit all Hyundai car owners whose engines malfunctioned. You only qualify for the compensation if you bought or leased the following units; 2011-2019 Hyundai Sonata, 2014-2015 Hyundai Tucson, and 2013-2019 Hyundai Santa Fe Sport.

The vehicles mentioned also had to be equipped with a genuine Theta II 2.0- or 2.4-liter gasoline engine within OEM specifications. Specific units manufactured in 2019 also qualified for the settlement since the Knock Sensor Detection System technology lacked in the engine’s configuration.

What Did Consumers Report About the Engine Malfunctions?

Numerous lawsuits against Hyundai claimed their engines were prone to defects. These defects included engine seizures, total failure, stalling, and fire. Most of the malfunctions were traced back to the connecting rod bearings in the Hyundai GDI engines.

According to one complaint, the fracturing of the connecting rod bearings released metal debris in the engine oil. Although there is an oil filter, it cannot purify the oil completely. Engine damage results from the contaminated oil circulating through its core and can cause unexpected engine failures.

The more these connecting rod bearings fracture, their tolerance deteriorates. Eventually, you’ll hear a “knocking sound” from your engine. There is a possibility the piston might break through your engine block, damaging other engine components.

Potential Rewards for the Hyundai Theta Engine Piston Settlement

Warranty Extension

You can receive a warranty extension as compensation for the Hyundai Theta settlement. Depending on your case, they may extend your powertrain warranty to a lifetime warranty. The warranty extension covers assembling the engine block, short block assembly, bearings and crankshaft, bearings, and connecting rods and pistons. Regardless, many consumers did not receive this warranty extension and had to purchase rebuilt Hyundai engines from retailers like Reman-Engine,

Repairs Reimbursement

Class members are guaranteed financial reimbursement. The compensation includes a full refund or repairs and a $140 goodwill payment.

Value Reduction Compensation

If you traded in your car for a lower value because of engine stall, failure, noise, or even compartment fire, you would receive compensation. A $140 goodwill payment accompanies the settlement.

Compensation for Engine Fires

Engine fires qualify you for compensation equal to the vehicle’s actual value.


You qualify for compensation if you have to buy a replacement vehicle because of the Hyundai Theta engine. Here is the class action for rebates;

  • $2,000 for 2011 and 2012 Class Vehicles
  • $1,500 for 2013 and 2014 Class Vehicles
  • $1,000 for 2015 and 2016 Class Vehicles

What Problems Are Common for the Hyundai Theta Engine

Engine Failures

One common complaint from numerous consumers was engine failures of the Hyundai Theta engine. Most of the malfunctioning engines were manufactured from 2011 to 2014 and included the Hyundai Sonata and Santa Fe. The rod bearings were the root cause of engine failures as contaminated oil flowed through the engine.


  • High oil consumption
  • Poor overall performance
  • Stalling
  • Engine Knocks


The best solution to fix engine failure in your Hyundai Theta would be a replacement. It does not make sense to rebuild the engine as the issue contributes to other engine problems that develop with time. The recalls and fines paid indicate that Hyundai was aware of this engine issue and made efforts to correct it.

Oil Consumption Issues

Excess oil consumption was also a concern with several Hyundai Theta engines. Although engines naturally consume oil, these engines consume more than usual. The main reason for excess oil consumption is the loss resulting from blow-by past the piston ring gaps. You may need to book an appointment with your garage if you start losing more than 1 quart of oil every 1,000 miles.


  • Burning oil smell
  • White exhaust smoke
  • Pinging or knocking sounds

Carbon Build Up Issues

The 2.4 Theta MPI engine did not have carbon build-up issues because of its multi-point injection system. However, the 2.4 GDI variant experienced these issues because of its inability to wipe away oil. The oil deposits stick to the valves, forming carbon deposits that block your engine’s core internally.


  • Misfiring
  • Loss of power
  • Stuttering on acceleration


It would be best to consider taking your engine for a complete checkup after five years or every 80,000 miles. Although it does not significantly impact compromising reliability and longevity, you still need to avoid it. The valve cleaning helps you regain lost power from your engine.


The Hyundai Theta engine is still a top performer despite the issues mentioned. You can find the engine in numerous Hyundai models; newer models have fewer problems. The Hyundai Theta engine settlement closed, but you can still look for other settlements to help with your situation.

Hyundai Bayon review

Hyundai Bayon review

We road test the newest addition to Hyundai’s growing family – the Bayon baby SUV…

I feel a bit sorry for the Hyundai Bayon. Not only has it been saddled with a name* which means nothing to most UK buyers, but it was introduced at around the same time as Hyundai’s acclaimed Ioniq 5 EV and Tucson SUV.

In other words, this worthy compact crossover – which will do battle with the likes of the Nissan Juke, Seat Arona, Ford Puma, Renault Captur and Skoda Kamiq – missed out on the launch limelight.

First impressions are mixed. Let’s be charitable and describe the design as bold. A huge grille sits below thin headlights, there are sharp creases down the side and it has an angular rear end with tall tail-lights and a thin horizontal light bar.

Hyundai Bayon review

Inside, it’s much the same as the i20 hatchback, the car on which the Bayon is based. The dashboard is attractive enough and sensibly laid out with top versions getting a pair of clear and crisp 10.25-inch digital screens – a digital driver’s display behind the steering wheel and a central touchscreen which takes care of media, navigation and car settings.

Naturally, it’s Android Auto and Apple CarPlay compatible, while Hyundai’s BlueLink smartphone app allows owners to connect with the car remotely, checking its location, status and sending routes to the sat nav for their next journey.

The Bayon range is priced from £20,530 and there are three trim levels offered: SE Connect, Premium and Ultimate.

Hyundai Bayon review

There’s only one engine available – a 1.0-litre three-cylinder turbocharged petrol (99bhp or 118bhp) with the choice of a six-speed manual or seven-speed automatic transmission.

The engine has 48-volt mild hybrid assistance and the more powerful version paired with the auto gearbox is capable of a 0-62mph in 10.4 seconds and a top speed of 115mph. Fuel consumption is as high as 53.3mpg, while CO2 emissions are as low as 119g/km.

My 118bhp test car in Ultimate spec came with a six-speed manual transmission and a ticket price of £24,780.

Hyundai Bayon review

Top trim means there’s plenty of kit, including black gloss door mirrors, two-tone black roof, keyless entry and a Bose sound system, on top of the rear view camera, privacy glass, heated front seats and steering wheel found on entry-level models.

There’s lots of safety and driver assistance equipment too including AEB (autonomous emergency braking), Blind Spot Collison Warning and Lane Follow Assist, Lane Keeping Assist and automatic high beams. Ford the record, it achieved a creditable four out of five stars in Euro NCAP crash tests.

The Bayon is surprisingly spacious inside with room for two adults in the back, though space for your feet below the front seats is limited. The boot is a reasonable 334 litres, expanding to 1,205 litres with the rear seats flipped down, and there are smaller storage spaces dotted around the cabin.

Hyundai Bayon review

My only gripe is that there’s too much scratchy, hard plastic used around the cabin.

I’m glad I was able to try the clever manual gearbox, which is marketed as an intelligent Manual Transmission (iMT).

Apparently, there’s no physical link between the clutch pedal and the clutch and it allows the engine to switch off temporarily while coasting, reducing emissions and saving fuel.

The system seems to work well enough on the move, though sometimes there is a hesitation with the stop-start when engaging first gear in slow moving traffic.

That said, the clutch is light, and the gear lever has a pleasant short throw, even if it is a bit notchy at times.

Hyundai Bayon review

The engine is more punchy than the performance figures suggest, and more importantly for many, it’s smooth and refined when up to speed.

You can choose between three drive modes (Eco, Normal and Sport). Eco is fine for motorway runs on cruise control (50mpg is achievable), but Normal is the best all-rounder and will do just fine, because Sport simply adds weight to the steering.

With its light controls and raised driving position, the Bayon makes sense as an urban crossover choice.

It would be wrong to call its firm ride sophisticated, but it’s comfortable enough.

Hyundai Bayon review

It’s light up front, so grip level is moderate in the wet or on a loose surface, but overall it handles well and body control is decent. So, while it’s not as engaging to drive as some rivals, it ticks plenty of boxes for most buyers.

Verdict: The Hyundai Bayon is an honest, competitively priced, boldly-styled new entrant in the busy compact crossover segment. Well equipped, easy to drive, practical and economical, it comes with an appealing five-year unlimited mileage warranty.

*Just so you know, the Bayon name is inspired by Bayonne, the capital of the French Basque country in the south-west of France.

Hyundai Ioniq 5

The Hyundai Ioniq 5 has won the treble at the 2022 World Car Awards after being named overall World Car of the Year, World Electric Vehicle of the Year and World Car Design of the Year.

The highly acclaimed all-electric crossover was honoured at a ceremony held at the New York International Auto Show (NYIAS).

The jury of 102 automotive journalists from 33 countries around the world considered the Ioniq 5 alongside 27 competitor models launched in 2021. Ultimately it claimed victory over the other finalists in all three categories in which it was nominated.

The Ioniq 5 beat two other finalists for the top award – the Ford Mustang Mach-E and the Kia EV6.

The two other finalists in the World Electric Vehicle of the Year were the Audi E-Tron GT and Mercedes-Benz EQS, while the runners-up in the World Car Design category were the Audi E-Tron GT and Kia EV6.

Since its launch, the Hyundai Ioniq 5 has won numerous accolades, including German Car of the Year, UK Car of the Year, Auto Express’ Car of the Year and Auto Bild’s Electric Car of the Year.

“We are truly honored to receive these prestigious awards, which recognize the talent and hard work of all our people and business partners at Hyundai Motor Company,” CEO and President Jaehoon Chang said.

Hyundai Ioniq 5 review

We road test the award-winning electric vehicle that instantly dates just about every other car on the road…

It’s difficult to know where to start with a car like the acclaimed Hyundai Ioniq 5. Already the winner of various Car of the Year titles, this futuristically styled EV features state-of-the-art technology and looks like nothing else on the road.

Hyundai may not thank me for it, but I’m going to start by pointing out that the Ioniq 5 shares its Electric-Global Modular Platform (E-GMP) with its Korean cousins, the Kia EV6 and the upcoming Genesis GV60.

Beauty is in the eye of the beholder, but I’d say the retro cool Ioniq 5 is easily the most distinctive of the trio. Park it next to any other competitor car (eg Volkswagen ID.4, Jaguar I-Pace or Ford Mustang Mach-E) and they look instantly dated.

Hyundai Ioniq 5 review

Bigger in the metal than I’d expected, it looks like it should be about the size of a VW Golf from the pictures, but it’s actually closer to a Skoda Enyaq iV.

Hyundai markets it as a “midsize CUV”, which is automotive industry speak for a Crossover Utility Vehicle – a blend of hatchback and SUV, for want of a better definition.

Competitively priced from £37,545, there’s a range of battery and motor options available, plus rear or all-wheel drive. Packed with technology and equally futuristic inside, it’s a revelation.

Hyundai Ioniq 5 review

Able to charge from 10-80% (via an ultra rapid 350kW chargepoint) in as little as 18 minutes and travel up to 298 miles on a charge, it can sprint from 0-62mph in just 5.2 seconds.

We tested the top-of-the range Ioniq 5 with twin-motor all-wheel drive and the largest battery size available (72.6kWh). Just shy of £50,000, it boasts a combined 301bhp and 446lb ft of torque.

The flush door handles pop out as you walk up to the Ioniq 5. Once inside, the benefits of the car’s larger dimensions and flat floor are obvious – it’s bathed in space and light.

Hyundai Ioniq 5 review

It’s ultra-modern and minimalist up front, thanks to a two-spoke steering wheel and panoramic twin-screen infotainment and driver’s display set-up.

There’s a sliding centre console incorporating cupholders, small storage areas and a wireless phone charger, while the versatile front seats can be fully reclined.

Comfort is subjective, and though the seats were nicely padded with plenty of adjustment, I just couldn’t get the perfect driving position. Such is the huge amount of cabin space, I felt perched and almost marooned at times.

Hyundai Ioniq 5 review

The bonus of such a high driving style is that there are no complaints in the visibility department, but ultimately the Ioniq 5 may be fast, but doesn’t feel so sporty.

There’s ample room for rear passengers, while the shallow boot still has a decent 527-litre capacity, expanding to 1,587 litres with the rear seated flipped. You can also store the charging cables in a space under the bonnet.

All versions are loaded with kit. Even the entry-level SE Connect model comes with the dual 12.3-inch screens, the impressive rapid charging capability, wireless smartphone charging, 19-inch alloy wheels and highway drive assist (an advanced version of adaptive cruise control).

Hyundai Ioniq 5 review

Move up to Premium for LED headlights, an electric driver’s seat, an electric boot, heated front seats and blind spot monitoring with collision avoidance.

Ultimate adds a head-up display, 20-inch alloys, Bose sound system, rear privacy glass and ventilated front seats.

To get moving, simply choose a gear (the shift stalk is mounted low right on the steering column) and you’re away – and it’s properly quick.

Hyundai Ioniq 5 review

You can also select Eco, Normal or Sport drive modes and adjust the brake regeneration. The ‘one-pedal’ option enables you to slow down to a halt just by lifting off the accelerator. It’s useful in town, but a little jarring on faster roads, where it’s easier to use the paddles behind the steering wheel for extra regen.

Frankly, Normal will do just fine. Eco is OK for cruising on a motorway or A-road, but a little lifeless otherwise, while Sport is fun for short, battery-draining bursts of fun.

If you’re looking for a comfortable ride, then the Ioniq 5 is the car for you. However, more spirited drivers might find it a little too floaty with rather too much body roll in faster corners.

Hyundai Ioniq 5 review

That said, there’s plenty of grip and the steering is light and easy, while the brakes are unusually responsive for an EV.

No car is perfect and the Ioniq is no exception. It’s not as dynamic to drive as some rivals, and some of the interior materials could be classier.

The lack of a rear wiper is a bigger issue than it might sound too, especially when it’s raining. I finally lost patience on one motorway journey, stopping the car at a service station to clean the rear window. Also, the steering wheel obscured some of the driver display behind with my set-up.

I tested the car in the winter so the 267-mile range (the AWD in top spec Ultimate trim with 20-inch wheels is 30 miles down on the RWD) was never on, but I’d say up to 240 miles is realistic in those conditions.

Hyundai Ioniq 5 review

Thankfully, advanced charging ability is the Ioniq 5’s party piece. In theory, it can add 62 miles of range in just five minutes, because it’s one of the few EVs on the market to support both 400V and 800V charging.

Using a more common 50kW charger, you’ll get up to 80% in 50 minutes, while a complete charge on a wall box at home is best done overnight.

Unless you need all-wheel drive, I suspect the sweet spot in the range is the cheaper 72.6kWh single motor version (RWD) with a potential range closer to the claimed 298 miles.

Verdict: The Hyundai Ioniq 5 is smooth, spacious, comfortable and easy to drive. Loaded with state-of-the art technology, it’s a competitively priced family EV that oozes kerb appeal.
