2019 Hyundai i40 problems

A 2019 Hyundai i40 is now 7 years old, so an average example has covered around 94,500 miles. The final model year of the generation · generally the most sorted build, so mileage, servicing and condition matter more than build-year faults. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2019 car has usually reached the mileage where they appear.

Quick answer

The 2019 Hyundai i40 is 7 years old, so an average example has covered roughly 94,500 miles. At that mileage 3 of the documented faults are already due, so check those first. A further 2 typically appear later in the car's life.

Faults a 2019 example has usually reached

Documented onset mileage is at or below the ~95k miles an average 2019 car has covered.

EngineHigh

DPF and EGR faults on the 1.7 CRDi

Typically appears
90,000+ miles
What to inspect
Check for regen warnings and run it hot
SuspensionMedium

Front bush and drop link wear

Typically appears
70,000+ miles
What to inspect
Listen for knocks over rough roads
SteeringMedium

Clicking or clunking noise when turning the steering wheel side to side, caused by a worn flexible coupling inside the electronic power steering (EPS) motor.

Typically appears
50,000-80,000 miles
What to inspect
With the engine running and the vehicle stationary, gently rock the steering wheel left and right. Listen for a distinct click or clunk echoing from behind the dashboard.

Faults that appear at any mileage

Age, electronics and build-related issues that are not mileage-driven.

ElectricalLow

Parking sensor and camera faults

Typically appears
Age-related
What to inspect
Test all sensors and the reversing camera
BrakesMedium

Rear caliper seizing on low mileage cars

Typically appears
Age-related
What to inspect
Check for uneven rear pad wear
Interior ElectricalMedium

Touchscreen infotainment and sat-nav unit freezing, rebooting randomly, or displaying a blank screen due to software corruption or mainboard failure.

Typically appears
5-8 years
What to inspect
Turn the ignition on and immediately test the touchscreen responsiveness. Cycle rapidly through the radio, media, and sat-nav menus to ensure the system does not lag, freeze, or crash.

Faults still ahead of this car

Typically appear later than this year's average mileage · worth budgeting for rather than inspecting.

TransmissionHigh

Clutch judder when pulling away in first gear or a rattling noise at idle, indicating dual-mass flywheel (DMF) wear on manual 1.7 CRDi models.

Typically appears
70,000-100,000 miles
What to inspect
Start the engine from cold. Listen for a metallic rattle that disappears when the clutch pedal is depressed. Test a pull-away in first gear to feel for driveline judder.
EngineHigh

Rhythmic ticking or metallic rattling from the engine bay on cold start due to timing chain stretch and tensioner wear on the 1.7 CRDi.

Typically appears
80,000-120,000 miles
What to inspect
Ensure the engine is completely cold. Start the car with the bonnet open and listen closely to the timing chain cover area on the left side of the engine for a harsh metallic rattle.

Hyundai i40 · frequently asked questions

Is the i40 a bargain?

Yes, values are low and fleet history is often complete.

Main watch out?

DPF condition on short journey cars.

Estate or saloon?

The estate is far easier to sell.

What is the reliability of the 7-speed DCT automatic gearbox?

The 7-speed dual-clutch transmission, introduced during the 2015 facelift, offers smoother shifts but requires careful inspection. It is prone to clutch pack wear and mechatronic unit faults, often manifesting as juddering at low speeds or hesitation when pulling away. Manual gearboxes are generally more robust, provided the dual-mass flywheel is healthy.

Does the 1.7 CRDi engine use a timing belt or a timing chain?

The 1.7 CRDi engine utilises a steel timing chain rather than a rubber timing belt. While designed to last the lifetime of the vehicle, the chain and its tensioners can stretch or wear on higher-mileage examples, especially if the vehicle has missed scheduled oil changes. Always listen for cold-start rattling.

Does the i40 still benefit from Hyundai's manufacturer warranty?

Hyundai supplied the i40 with a five-year, unlimited-mileage warranty from new. As production ceased in 2019, even the very last registered models have now fallen outside this manufacturer coverage. Dealers must ensure any aftermarket warranties offered cover known weak points like the dual-mass flywheel, steering coupling, and infotainment unit.
