Known problems
- Worth watching
7DCT low-speed jerkiness
Symptoms: jerky or hesitant engagement and delayed take-up when crawling in stop-and-go traffic; occasional clunk from a standstill
What to do: This is largely a trait of the wet 7-speed dual-clutch rather than an automatic, but keep the transmission software updated at the dealer and change the DCT fluid on schedule. Have it checked if the jerking comes with warning lights, slipping, or overheating messages.
- Good to know
Infotainment and software glitches
Symptoms: touchscreen lag, occasional black screen or spontaneous reboot, rear/surround camera dropping out, and spurious warning messages; some rough Russian-menu translations
What to do: Most of these are resolved by a head-unit software update or reset at the dealer. Note the exact conditions that trigger the fault so service can reproduce and reflash it.
- Good to know
Interior trim rattles and minor sealing complaints
Symptoms: dashboard and door-trim squeaks after some months of use; isolated reports of damp or water ingress around windshield and door seals
What to do: Have squeaks traced and trim re-clipped under warranty. If you find fogging or damp carpet, ask the dealer to check door and windshield seal fitment early rather than living with it.

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.
