Before you buy a used Hyundai Tucson (IV).
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 4 engines.
- 4 of them depend on the equipment or the production date: ask what this car has.
- 6 official recalls on record: ask for the chassis number (VIN) and confirm they have been done.
- According to the data we have, the engines with the fewest documented faults are: 1.6 T-GDi Hybrid (Hybrid), 1.6 T-GDi Plug-in Hybrid (Plug-in hybrid), 1.6 CRDi (Diesel).

- 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: U-family CRDi diesel; the specific points were documented on other models with the same engine.
Which engine has the fewest documented faults?
| Engine | Documented faults | Recalls |
|---|---|---|
| 1.6 T-GDi / 48VPetrol | 43 with conditions | 5 |
| 1.6 T-GDi HybridHybridFewest documented | 32 with conditions | 6 |
| 1.6 T-GDi Plug-in HybridPlug-in hybridFewest documented | 32 with conditions | 6 |
| 1.6 CRDiDieselFewest documented | 33 with conditions | 5 |
According to the data we have, the engines with the fewest documented faults are: 1.6 T-GDi Hybrid (Hybrid), 1.6 T-GDi Plug-in Hybrid (Plug-in hybrid), 1.6 CRDi (Diesel).
By fuel type, the ones with the fewest documented faults are: Hybrid, Plug-in hybrid, 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.
- 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.

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.
Visibility / electronics
Look out for: When switched off, the front wipers do not go back down: they stop halfway up the glass or in a different place each time. They sweep normally while working.
Ask them to check: Tell the garage that they stop in different places when switched off and ask them to check the tightness of the motor crank arm nut before replacing the wiper motor. The warranty extension is for the US; in Europe, ask the dealer.
Known weak points
Look out for: Rattles from badly fitted trim or wheel-arch liners, water leaks after heavy rain and, on the 48 V system, stop-start that only works with a well-charged battery.
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.
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.
