- Hybrid Battery / Charging BugsModerate
PHEV models can occasionally show charging faults or fail to engage electric mode due to software glitches.
- Frameless Door Glass Regulator & Microswitch StickingModerate
The frameless door windows must automatically index down 10mm when opening. Faulty door handle microswitches or regulator friction can cause the glass to catch against the roof weatherseal, causing seal tears and wind rush.
