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.

|---|---|---|
| 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) |

| Timing chain inspection | — | chain-driven (BlueCore) — inspect for noise rather than scheduled replacement |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
