    What the sheet says: German guides rate these engines as robust if maintained: the faults are the typical wear of a modern diesel. Specific points: a stretched chain on some 1.7s (ix35), cracked heads cited by the TÜV on the i30 I, the 1.1 silencer (Rio III), diesel clutches at 60,000–100,000 km (Cee'd I) and a recall of the 1.7 CRDi vacuum pump (5/10/2010–30/4/2011).

    Applies if: U-family CRDi diesel; the specific points were documented on other models with the same engine.

According to the data we have, the engine with the fewest documented faults is the 1.2 / 1.4 (Petrol).

By fuel type, the one with the fewest documented faults is: Diesel.

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

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  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.

How to check it: Check by VIN whether any of the recalls is outstanding (at the dealer or on the DVSA website) and carry out the inspection or replacement it requires.

0 of 4 checked

Known weak points

  • Look out for: The 1.2 feels sluggish pulling away; on the 1.0 T-GDI, carboned injectors and intake; with the 7-speed dual clutch, judder when pulling away and overheating warnings in traffic; a radio that freezes, bulbs that blow and the alternator.

    Ask them to check: Test the dual-clutch in traffic; check lights and alternator; clean the 1.0 T-GDI intake if it loses power.

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.

  • Look out for: At high mileage or with short trips: carbon in injectors and EGR, a clogged particulate filter, dual-mass flywheel and turbo; isolated cases of a stretched chain (1.7) and cracked heads (early 1.6); a clutch that wears early; on some cars, a cracked silencer (1.1) or the brake-servo vacuum pump (1.7 campaign).

    Ask them to check: Drive long trips to regenerate the filter; listen to the chain when cold; test injectors and EGR; check the vacuum-pump campaign by VIN on the 1.7.

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.
