Before you buy a used Hyundai ix35.
Taken only from Testigo's sourced sheets. Use it to question the seller and on the test drive: it does not confirm that any particular car is affected.

The essentials.
- 5 documented, sourced faults across its 3 engines.
- They all depend on the equipment or the production date: ask what this car has.
- 3 official recalls on record: ask for the chassis number (VIN) and confirm they have been done.
- According to the data we have, the engine with the fewest documented faults is the ix35 Fuel Cell (Electric).
Typical faults by engine
The period and mileage are those mentioned by each sheet's sources. They are not a maintenance interval and do not predict that any particular car will fail.
All versions
Sheets the catalogue links to all 3 of its engines.
- Steering joints, drive shafts, starter and recalls on the ix35Known weak points
- Period mentioned
- 2010–2015
- Mileage mentioned
- The sheet does not mention a mileage.
Applies if: Weak points of this model from inspections, breakdown statistics and recalls; anything specific to one engine is stated in the sheet.
Applies if: The fuel-cell ix35 shares the body and chassis: the ball-joint, driveshaft and body-campaign points apply.
1.6 / 2.0
Petrol
- Period mentioned
- 2009–2019
- Mileage mentioned
- The sheet does not mention a mileage.
Applies if: Only the 2.0 petrol (Theta II); confirm by VIN.
- Period mentioned
- 2012–2016
- Mileage mentioned
- The sheet does not mention a mileage.
Applies if: Only the 1.6 GDI (Gamma); the campaigns cited are from the US: confirm by VIN.
1.7 / 2.0 CRDi
Diesel
- Period mentioned
- 2009–2014
- Mileage mentioned
- What the sheet says: The guide recommends replacing the chain at around 100,000 km to stop it breaking. The fuel filter often clogs and the clutch wears out before 60,000 km when towing. On the automatic, changing and flushing the oil helps.
Applies if: Same R-family CRDi diesel (D4HA/D4HB) as the Sorento II, where the German guide documents the chain and fuel filter.
- Period mentioned
- Approx. 2005 onwards
- Mileage mentioned
- 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: Only the 1.7 CRDi (U family); the 2.0 CRDi belongs to the R family.
ix35 Fuel Cell
Electric
We have no faults specific to this engine, only those common to every version.
Which engine has the fewest documented faults?
| Engine | Documented faults | Recalls |
|---|---|---|
| 1.6 / 2.0Petrol | 33 with conditions | 3 |
| 1.7 / 2.0 CRDiDiesel | 33 with conditions | 3 |
| ix35 Fuel CellElectricFewest documented | 11 with conditions | 3 |
According to the data we have, the engine with the fewest documented faults is the ix35 Fuel Cell (Electric).
By fuel type, the one with the fewest documented faults is: Electric.
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.
- 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.
- 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.
- 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.

Engine
Look out for: Metallic engine knock that rises with revs, oil-pressure warning, loss of power and, in the worst case, a broken connecting rod with an oil leak and fire risk.
Ask them to check: Ask Hyundai or Kia by VIN about a campaign or KSDS update; with knocking or the oil warning, stop and do not keep driving; check the oil level often.
Look out for: Engine knock, oil-pressure warning and loss of power; with an overheated catalytic converter, abnormal combustion that damages the pistons.
Ask them to check: Ask by VIN about an outstanding campaign; with knocking or the oil warning, stop. Check the catalytic converter if there is hesitation or loss of power.
Known weak points
Look out for: Poor roadworthiness-test results for steering joints, drive shafts, lights and brakes; a starter that fails more than normal on the petrols; on the 1.7 CRDi, isolated cases of a stretched chain; rust on the tailgate on some cars.
Ask them to check: Check outstanding recalls by VIN (manufacturer, KBA or ADAC website) and have a garage inspect the points listed before buying or before the roadworthiness test.
Timing system
Look out for: Chain noise at high mileage, hesitation or loss of power from a clogged fuel filter, turbo whistle and a worn clutch when towing; on automatics, harsh shifts.
Ask them to check: Listen to the chain when cold, change the fuel filter on time and test the clutch under load; on automatics, check the gearbox oil.
Injection / turbo
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.
