The vehicle was in the middle of a u-turn when the ICCU fuse suddenly and without warning blew. Display warning messages came on to "check electrical system". Car was able to drive in "limp mode" at about 40 mph on level roads, but not more than 25 mph on any uphill. This is a well known problem with Hyundai EVs. It will be towed to a dealer to confirm. It felt extremely unsafe to be in the middle of a turn on a public street and have the car power system fail. Luckily there was minimal traffic at the moment. A few minutes earlier or later would have been on a heavily trafficked road
