1.2PetrolFewest documented11 with conditions

According to the data we have, the engine with the fewest documented faults is the 1.2 (Petrol).

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

We have no official recalls on record for this model. Our list is not complete: ask anyway, with the chassis number.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Hyundai dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

0 of 3 checked

Injection / turbo

  • Look out for: Loss of power, higher consumption, hesitation or rough idle, usually at high mileage.

    Ask them to check: Read misfire and fuel-trim codes; inspect the injectors and valves with a borescope; clean the intake if there are deposits.

Known weak points

  • Look out for: Rattles on the driver and passenger sides, squeaks from the rear axle (rear brakes) and carbon on the T-GDIs at high mileage; on the naturally aspirated 1.2 the guide knows of no engine problems.

    Ask them to check: Check the eCall campaign by VIN; check the rear brakes if they squeak.

Automatic gearbox

  • Look out for: Abnormal vibration or shudder when pulling away and at low speed, especially in traffic.

    Ask them to check: At the dealer: run the judder test with the diagnostic tool, install the latest gearbox software and replace the dual clutch only if the judder remains.
