The Sonata is a lot of car for the money, and that is exactly why you must check the engine.

Some of these engines failed outright. There were recalls, warranty extensions, and engine replacements.

2.0L turbo
1.6L turbo (2015+)
2.0L hybrid

Known problem areas — what we check

Costly Safety Common Verify

Engine failure and rod knockCostly

Some 2.4 and 2.0 turbo engines wear a bearing and knock, and a few seize entirely. There were recalls and extended warranties covering it.

WE CHECK We listen at idle for a deep knock, check oil condition, and ask whether the engine was ever replaced.

Knock sensor software campaignSafety

A software campaign was issued to detect bearing wear early and protect the engine.

WE CHECK We check whether the campaign was applied and scan for stored engine faults.

Oil consumptionCostly

These engines can use oil, and low oil is what kills the bearings.

WE CHECK We check the oil level and ask directly how often it needs topping up.

Dual-clutch behaviour (1.6 turbo)Verify

The 1.6 turbo uses a 7-speed dual-clutch that can feel jerky at low speed.

WE CHECK We drive it in slow traffic and feel how it takes up and shifts.

Electric power steeringCommon

Some earlier cars had power steering noise and faults.

WE CHECK We test the steering at low speed and listen for noise.

Paint and clear coatCommon

Some cars lose clear coat on the roof and hood.

WE CHECK We look over the horizontal panels in daylight.

Common service bulletins (TSBs)

A TSB is a note the maker sends to dealers about a known fix. They are not recalls. We check the bulletins so we know what to look for:

Engine & Drivability76

Cold-start noise, drivability, and idle issues for this vehicle. We test for each.

Power Train · Automatic20

Shift quality and transmission fluid updates. We drive every gear.

Electrical & Body167

Locks, wipers, infotainment, and trim items. Small, but good to know.

Counts are pulled from NHTSA's public Manufacturer Communications file. Full bulletins stay with the maker — we use the summaries to guide the inspection.

Common questions

Is it true Sonata engines fail?

Some did, and there were recalls and warranty extensions covering it. A car with a replaced engine can be a good buy. One with an original untouched engine and a knock is not. We tell you which you have.

How do I know if the engine was replaced?

Service records, and there are physical tells. We look for both.

Where do you inspect?

All 48 states.

Do you pull recalls?

Yes, plus service bulletins.
