Known problems
- Worth watching
7DCT low-speed jerks/shudder (and factory oil under-fill)
Symptoms: jerking, slipping on take-off and shudder at low speed, more pronounced in stop-go traffic or when the wet clutch overheats; some cars left the factory with the dual-clutch under-filled, which aggravates the jerking until topped up
What to do: Have the dual-clutch fluid level checked and topped to spec and the TCU software updated; keep the fluid on a shortened change interval for city use, and test-drive in traffic when buying used.
- Worth watching
Elevated oil consumption on some engines
Symptoms: higher-than-expected oil use, sometimes noticed by the first service or on higher-mileage engines (reports around 0.3-0.5 L/1000 km on affected cars)
What to do: Check the oil level regularly between changes, use a correct API SP 5W-30 oil and keep the crankcase-ventilation (PCV) system healthy; raise it under warranty if consumption is high.
- Worth watching
New car pulls to one side; wheel alignment often needs correcting
Symptoms: a pull (usually to the right) or tramlining in ruts from very low mileage with the steering wheel centred; some cars need more than one alignment visit
What to do: Check it on a straight, level road before accepting the car; if it pulls, ask the dealer for a full four-wheel alignment early, while it is covered.
- Good to know
Head unit freezes or drops Bluetooth audio
Symptoms: the touchscreen occasionally stops responding, Bluetooth audio cuts out while the phone still shows a connection, and in rare cases the unit stays on after the car is locked
What to do: A forced reboot (long press of the power button, or briefly disconnecting the 12V battery) usually clears it; ask the dealer for head-unit software updates. It is not linked to any drivetrain fault.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | turbo — shorten to ~7,500 km for city use; API SP 5W-30. Check the level (some cars burn oil at run-in) |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 25,000 mi (40,000 km) | turbo direct injection |
| 7DCT (wet dual-clutch) fluid Important | every 37,000 mi (60,000 km) | check for a factory oil under-fill; shorten the interval for heavy city use |
| Brake fluid Important | every 36 months | — |
| Timing chain inspection | — | chain-driven (BlueCore) — inspect for noise rather than scheduled replacement |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 1.5T CS55 Plus (RU 2019+, incl. 2021 restyle) · 2019–present | — | — | 40 mpg (5.9 L/100 km) | NEDC |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under EPA, WLTP, NEDC or JC08 can differ by up to 20%. Real driving always falls short of the declared figure: roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one. That gap is normal, not a fault.
