Crank but no start. After being driven for approximately 15 minutes and parked at the shops, the vehicle would not restart. It started the next day. Since then it has not repeated the complete no-start, but occasionally cranks longer than normal before starting.

Intermittent slow crank/extended crank leading to an occasional no-start. Fuel pressure and immobiliser/smart key functions appeared active, but system voltage dropped significantly during cranking. Excessive starter current draw was observed.
