- Level 2 home chargers stop charging or throttle current after roughly twenty minutes, with owners describing the charge port as overheating.
- The Integrated Charging Control Unit (ICCU) fails, sometimes triggering a dashboard power-supply error code, loss of drive power ('turtle mode'), or the vehicle stalling in the road.
- Some owners report the ICCU failed again days after a recall repair, or that the dealer only updated software instead of replacing the unit as the recall directed.
- The low-tone horn stops working, sometimes at very low mileage, leaving only the high-tone horn functional or no horn sound at all.
- Headlights fail to properly illuminate the road ahead, creating dark zones to the side and front of the vehicle, especially when turning.
- One owner reported a Battery Management System replacement was needed shortly after an ICCU recall repair, after multiple service visits.
