Common Hyundai Sonata problems and related parts

Hyundai Sonata problems to diagnose before choosing parts on Speero include a knock in some 2.4 litre engines of the 2011 to 2014 models, a click in the steering, weak air conditioning in summer, worn suspension parts, overheating with a falling coolant level, and an illuminated check engine light. Catching early signs may limit damage, but diagnosis determines the repair needed.

Speero lists genuine (dealer) and aftermarket Sonata parts across 12 categories, from A/C and cooling to bumpers and grilles, covering model years 1991 to 2027. Pick your car's year on the Hyundai Sonata parts page and only the parts that fit it appear.

1. Engine knock in 2.4 engines (2011 to 2014)

Before buying parts on Speero for a Sonata engine knock, have a specialist identify the cause. Some 2.4 litre engines in the 2011 to 2014 Sonata were subject to recall campaigns in some markets over the crankshaft bearings.

Signs: a knock from the bottom of the engine that rises with speed, the check engine light, and a loss of power.

What to do: have the car checked by a specialist at once. Ask the dealer whether your car is covered by a recall before paying for any repair. Read the crankshaft: its job and failure signs and causes of low engine oil pressure.

2. A click in the steering

Before ordering steering parts from Speero, have the source of the Sonata's noise checked; this click shows up in some 2011 to 2014 models in particular.

Signs: a tick when you turn the wheel while stopped or at low speed.

Related parts: the steering column coupling. You find it in the Steering category once you pick your car's year.

3. Weak air conditioning in summer

Speero lists Sonata A/C parts, and summer heat can expose weak cooling performance.

Signs: lukewarm air, a noise when the compressor engages, and water dripping inside the cabin.

Related parts: the compressor, the cabin filter, the evaporator and the fan, all in the A/C category. Read signs of a failing A/C expansion valve and signs of a worn cabin filter.

4. Suspension noise over bumps

Sonata suspension parts are listed on Speero, and speed bumps and uneven roads can contribute to wear.

Signs: a knock over bumps, and heaviness or shake in the steering.

Related parts: front shock absorbers, stabiliser links and control arms, in the Suspension and arms category. Read signs of worn control arms.

5. Overheating and a falling coolant level

If your Sonata overheats, stop safely and switch off the engine before looking for a part on Speero. Let the engine cool, never open a hot radiator cap, and have the cooling system checked to identify the cause.

Signs: coolant dropping with no visible leak, and the temperature gauge climbing in traffic.

Related parts: the radiator, the radiator cap, the hoses and the thermostat, in the Cooling category. Read why the radiator loses coolant.

6. Check engine light and the oxygen sensor

Before choosing a part on Speero for a Sonata with a check engine light, have a specialist read the fault codes and diagnose the cause. A sensor or spark plugs may be involved, but the light does not rule out a serious fault.

Signs: the check engine light, and higher fuel consumption.

Related parts: the oxygen sensor, the spark plugs and the ignition coils, in the Spark plugs and coils category. Read why the check engine light comes on and goes off.

Sonata generations: why the year decides the part

Speero lists Sonata parts by year because the car's design and parts differ between generations. The 2005 to 2010 models are one generation. Then 2011 to 2014 brought an entirely new shape, the generation the engine and steering notes above refer to. Then 2015 to 2019 brought a calmer design, with an exterior update from 2018 that changed the bumpers and headlights. From 2020 the current generation carries more electronics. Do not use the generation alone to confirm fitment for body, lighting or mechanical parts. So pick your car's year on the Sonata page before any part, and match the old part number and vehicle specifications before ordering.

Genuine or aftermarket for Sonata parts?

Speero lists Sonata parts as genuine (dealer) and aftermarket, and each part's page states its kind. Genuine suits sensors, engine parts and brakes. Aftermarket is the economical choice for filters and body parts. For the detailed comparison read genuine versus commercial Hyundai parts, and for other Hyundai models see the Hyundai parts page.

Frequently asked questions

What is the most common Sonata fault?

Parts orders on Speero alone cannot establish the most common Sonata fault. Faults vary with the car's year, condition and maintenance.

Does the Sonata 2.4 have an engine problem?

Some 2.4 engines in the 2011 to 2014 models were subject to recall campaigns in some markets, so check with the dealer before buying parts on Speero. If you hear a knock from the bottom of the engine, have it checked at the dealer or by a specialist before anything else.

Do Sonata 2016 parts fit a 2018?

Do not assume that Sonata 2016 parts listed on Speero fit a 2018 just because both belong to the 2015 to 2019 generation. Bumpers and headlights changed with the 2018 update, so match the part number before ordering.

Yes, Speero covers Sonata model years up to 2027. Pick the year on the Sonata page to see the parts listed for it.
