2024 Hyundai Bayon problems

A 2024 Hyundai Bayon is now 2 years old, so an average example has covered around 27,000 miles.

Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2024 car has usually reached the mileage where they appear.

Quick answer

The 2024 Hyundai Bayon is 2 years old, so an average example has covered roughly 27,000 miles. At that mileage most documented faults are still ahead of it, so servicing evidence matters more than wear. A further 5 typically appear later in the car's life.

What to inspect
Cold start and check idle quality

Jerky gear changes or failure to engage the clutch smoothly on iMT (Intelligent Manual Transmission) models due to actuator hesitation.

Typically appears
20,000-40,000 miles
What to inspect
Depress the clutch pedal with the engine off to listen for excessive actuator clicking, then test for smooth take-up during a low-speed forecourt manoeuvre.
SuspensionLow

Clunking or knocking noise from the front end caused by premature wear of the front anti-roll bar drop links.

Typically appears
30,000-50,000 miles
What to inspect
Rock the vehicle side to side aggressively while stationary and listen for knocks, or drive over a forecourt speed bump at low speed with the windows down.
DrivetrainHigh

Juddering or hesitation when pulling away from a standstill on models equipped with the 7-speed DCT, indicating dry clutch pack wear or overheating.

Typically appears
40,000-60,000 miles
What to inspect
Perform a hill start or pull away very slowly from a standstill on the forecourt; feel for vibrations through the seat or hesitation before the clutch fully engages.

Hyundai Bayon · frequently asked questions

Is the Bayon a safe buy?

Yes, very low fault rate so far.

Warranty?

Five years transferable, which helps resale.

Weak point?

Interior plastics rather than mechanicals.

Does the 1.0 T-GDi engine use a timing belt or a timing chain?

The 1.0-litre T-GDi engine fitted to the Bayon utilises a timing chain rather than a belt. While designed to last the lifetime of the vehicle, chain stretch can occur if previous owners have neglected scheduled oil changes. Always verify the service history to ensure correct grade oil was used at the required intervals.

What should I look out for with the Intelligent Manual Transmission (iMT)?

The iMT features an electronic clutch-by-wire system, meaning there is no mechanical link between the pedal and the clutch. Ensure the system engages smoothly without hesitation. If the pedal feels disconnected or the car stalls unexpectedly during forecourt manoeuvres, it may require a software update or a new clutch actuator.

Does the 48V mild-hybrid system affect boot space or spare wheel provision?

Yes, the 48V lithium-ion battery is located under the boot floor. This reduces the overall luggage capacity slightly compared to non-hybrid models and completely removes the space required for a spare wheel. Dealers must ensure the tyre inflation kit is present and in date, as customers often query the lack of a spare.
