Theta II bearing wear
- Sign
- Knock rising with revs or low oil. Manufacturer recalls blamed debris starving the rod bearings.
- What we do
- Check oil pressure, then ask the dealer about your VIN.
Mechanics offers independent Hyundai service and repair in Al Quoz, Dubai for the Tucson, Santa Fe, Elantra, Sonata, Creta, Accent and Palisade. A knock from a Theta II engine, a dual clutch gearbox that hesitates in traffic or AC that fades by noon? We find the cause and quote in writing first.

The same Tucson can have three different engines and three different gearboxes. Pick your model and year to see the likely pairing, and the Theta II, DCT or recall checks that apply.
Send your Hyundai model, year and a photo of the VIN plate on WhatsApp. We reply with the engine and gearbox it has, the checks that apply and a written quote.

Hyundai at a glance
Twelve jobs cover almost every Hyundai that reaches our Al Quoz workshop. Each one starts with a free inspection and a written quote, and each links to its own Hyundai page.
Serviced to the Hyundai schedule with the right grade oil and filters, a code scan and an itemised invoice for your records.
Knock, oil use or misfires on the Theta II, Nu, Gamma or Smartstream. We test oil pressure, compression and codes before quoting.
Harsh or late shifts on the 6 and 8 speed automatics. We check fluid condition, codes and software before any gearbox work.
Judder or hesitation on the 7 speed DCT, or whine on the IVT. Clutch learning, software and fluid checks come first.
Warm air in traffic. We leak test the system, check the condenser fan and compressor, then regas or repair with a written price.
Squeal, judder or a soft pedal. We measure pads and discs and quote genuine and aftermarket parts side by side.
Knocks over speed bumps or uneven tyre wear. We inspect links, bushes and shocks on the lift before quoting.
A clunk through the wheel on older Elantra, Sonata and Santa Fe is often the steering coupler. We confirm it first.
Slow cranking after summer heat. We load test the battery and alternator, then fit and register a new battery.
A rising gauge or sweet smell. We pressure test the system, then refill with coolant of the right Hyundai type.
A dead fob or a car that will not recognise its key. We test the battery and fob, then repair or program.
Parking scrapes and bumper damage. We repair and paint, then check parking sensors and cameras still work.
Most Hyundais run a long time on basic care, but a few engines, gearboxes and parts have a documented history. Pick your model family to see the sign and what we check first.
Theta II from Wikipedia (Hyundai Theta engine) and Theta II lifetime warranty report (October 2019). ABS from park outside recall alert (September 2023). Steering coupler from Rick's Free Auto Repair Advice (bulletin 14-ST-002-1). DCT from recall notice 16V-628 (August 2016), Hyundai bulletin 17-01-024 (March 2017) and the Hyundai owner's manual, DCT warning messages. Palisade seats from Wikipedia (Hyundai Palisade). All checked 14 October 2026. Ask the UAE dealer to check your VIN.
A knocking engine and a weak AC are not the same problem. Read across each row to decide what to do next, and send us a photo of the dash if you are unsure.
Hyundai in the UAE uses five petrol engine families and four kinds of gearbox. Knowing the pairing tells us where to look first, and tells you what to watch between services.
| Engine | Gearbox | Models | What it means for you |
|---|---|---|---|
| 1.6 Gamma MPi | 6 speed automatic | Accent 2018 to 2022, Creta 2016 to 2020, older Elantra | Simple and long lived. Most work is oil, AC, brakes and gearbox fluid. |
| 2.0 Nu MPi | 6 speed auto or IVT | Elantra 2016 to 2020, Tucson 2016 to 2021, Kona | A steady everyday engine. Keep the oil topped up between services. |
| 1.5, 1.6 and 2.0 Smartstream MPi | IVT | Accent 2023 on, Creta 2021 on, Elantra 2021 on, Kona 2024 on | The IVT needs healthy fluid; Dubai heat ages it faster. |
| 2.4 Theta II and 2.0 Theta II turbo | 6 speed automatic | Sonata 2011 to 2019, Santa Fe 2013 to 2020, Tucson 2.4 | Recall and extended engine warranty history. Listen for knock and check oil level often. |
| 1.6 T-GDi turbo | 7 speed DCT | Tucson, Kona, Elantra Sport | Hold the brake on slopes and do not creep on the throttle. Judder needs a software and clutch check. |
| 2.5 Smartstream | 8 speed automatic | Sonata 2020 on, Tucson 2022 on, Santa Fe 2021 on, Palisade 2026 on | Strong and modern. Most likely still under warranty. |
| 3.3, 3.5 and 3.8 V6 | 6 or 8 speed automatic | Palisade, Azera, Staria, older Santa Fe | Big engines in Dubai heat. Cooling and oil leaks are the checks that matter. |

Conventional automatics with a torque converter. Smooth and tough; shift quality depends on fluid and software.
Hyundai's CVT with a steel belt. Smooth and frugal, but whine or flare means a fluid check first.
Two dry clutches, quick shifts, on the 1.6 turbo. Dislikes creeping in traffic and on ramps.
A wet dual clutch on some 2.5 turbo Santa Fe models. Needs the correct fluid and software.

What moves your price: the engine and gearbox, genuine or aftermarket parts, and whether the fix is software, fluid or a part. A Palisade V6 takes more oil and bigger brakes than an Accent.

Ask on WhatsAppMechanics in Al Quoz is an independent Hyundai workshop for the Tucson, Santa Fe, Elantra, Sonata, Creta, Accent and Palisade, covering servicing, Theta II engine checks, DCT and automatic gearbox faults, AC and brakes. You get a free inspection and a written quote first. Warranty and recall work stays with Juma Al Majid.
Juma Al Majid is the official Hyundai distributor in the UAE. Hyundai UAE offers a 5 year factory warranty, and iCarTea reported 5 years or 150,000 km with 5 years of roadside assistance on recent offers. Check your own booklet, because terms change with the sale date.
An oil and filter change on an Elantra or Accent costs about AED 200 to 350 at an independent garage and AED 350 to 500 at a dealer, as a guide, according to YallaMotor in July 2026. A 60,000 km major service runs about AED 1,285 to 2,020 for a sedan.
It may be if it has the 2.4 or 2.0 turbo Theta II, fitted to the 2011 to 2019 Sonata, 2013 to 2019 Santa Fe and some Tucsons. Manufacturer recalls and lifetime engine cover applied to affected cars. Ask Juma Al Majid to check your VIN, and book a check if the engine knocks.
The 7 speed dual clutch gearbox on 1.6 turbo models can hesitate or judder pulling away, especially in heat and slow traffic. Hyundai issued software updates for it. We check software level, clutch learning and codes, then road test before suggesting any clutch work.
It means the dual clutch gearbox has overheated, usually after crawling uphill or in stop go traffic, and has protected its clutches. Stop safely, select Park and leave the engine running until the dash says it has cooled. If it keeps happening, book a clutch check.
The usual causes are a slow refrigerant leak, a dirty or damaged condenser, a weak condenser fan or a tired compressor. We leak test first rather than just regassing. An AC service on a Hyundai in the GCC costs about AED 250 to 700 as a guide, according to YallaMotor.
On older Elantra, Sonata, Santa Fe and Azera models a click or thud through the wheel at parking speed is often the rubber steering coupler. Hyundai bulletin 14-ST-002-1 covers its replacement. It does not affect steering control, but we confirm it on the lift before replacing.
It depends on the job and on parts. Services, brakes, batteries and AC checks are usually short visits, while engine, gearbox and electrical faults need diagnosis first. We give you the expected time in writing with the quote, including any parts lead time.
Usually yes, if the body is sound and the repair costs less than the value you lose selling it faulty. Most brakes, AC, steering and gearbox fluid jobs make sense. A seized Theta II engine on an old car is the one case where the numbers need a careful look first.
Yes. We listen to the engine from cold, road test the gearbox, ask the dealer about open recalls, measure AC output and check steering, brakes and the underbody on the lift. You get the results in writing before you pay. Dubizzle Dubai listed 535 used Hyundais on 14 October 2026.
We quote genuine Hyundai parts and quality aftermarket options side by side, so you choose with the prices in front of you. Fluids for the DCT, IVT and automatic gearboxes must match the Hyundai specification. Cars still under warranty should go to Juma Al Majid for covered repairs.
Send the model, year and the problem or service due. We inspect free of charge, check warranty and recalls, and give you a written quote before any work.
