Have lost power steering, brakes, and engine twice at different inclines, low/moderate speeds and while or after turning right. Both caused by a blown fuse (once fuse27, then after repair fuse70). During the second occasion this almost caused a serious and significant accident. Clearly there is an electrical issue as it happened a second time after repair by the dealership. Loss of power is sudden and in my case the vehicle would not restart because the fuse was blown.
