This happened to me a second time today. It happened first on New Year's Eve (rather alarmingly for my SO as she was driving, and just about to turn off a freeway). In common with other reports, stopping the car and restarting it remedied the problem. I took it to the dealer as soon as possible afterwards. It seems that, like me, they hadn't heard of the problem before, and their solution was to replace the vacuum pump (under warranty). It happened to me, though, this evening. Fortunately first time it happened in a car park and I was able to cycle the car readily enough. It happened again though shortly afterwards as I was heading home on the freeway (light traffic, and traveling deliberately *slowly*, but disconcerting enough nevertheless. As points of note: Mine is a very early Hybrid, I got one of the first deliveries in the area. It also has a secondary alarm system fitted to it (by the dealer). I will be taking it back for service tomorrow (and not diving anywhere other than to the dealership), and alerting them to the issue. I'll also be making a case for getting a refund on the alarm system...
