Plug-in Hybrid
During your drive, toggle between 'Electric' and 'Hybrid' modes multiple times to ensure the transition is seamless and lacks any noticeable shudder or hesitation.
Use the MBUX infotainment screen to check the 'EQ' menu while charging or driving to confirm that the battery state-of-health and energy flow animations are responding without lag.
While driving over uneven road surfaces at low speeds, listen carefully for any creaks from the interior trim or panoramic roof seals, as these can occasionally develop in early models.
When parking, check that the 360-degree camera system activates instantly and displays a clear image, ensuring there is no delay in the digital processing which could indicate a software or module issue.
Routine minor service including cabin filter and thorough brake inspection due to regenerative braking usage.
Major service point; consider a transmission fluid flush and spark plug replacement to maintain engine efficiency.
Comprehensive check of the high-voltage cable integrity and cooling system for the battery pack.
Keep the charging port clean and ensure the locking mechanism clicks firmly into place to avoid charging interruptions.
Prioritize getting the MBUX system software updated at your local dealer to ensure the best battery management performance.
Regularly monitor your tyre pressures, as the hybrid weight can lead to uneven wear if they are not maintained at optimal levels.
Ensure the 12V auxiliary battery is tested annually, as its health is crucial for the hybrid system to wake up properly.
Check the brake fluid moisture levels occasionally, as regenerative braking means the mechanical friction brakes are used less frequently.
Estimated repair costs if issues arise
If this component needs attention in the future, it is worth noting that while the air suspension offers a refined ride, the air bellows can naturally wear over time. Depending on the car's history, you might eventually need to budget for a sensor or bag replacement.
The hybrid cooling system is quite sophisticated. If this system needs attention in the future, it usually involves checking the specialized coolant pumps. It is wise to set aside some funds for a potential flush or pump replacement as the vehicle ages past the warranty period.
