I've owned a 2018 PHEV Clarity for two weeks and put a few hundred miles on the vehicle mostly on EV mode. This weekend I wanted to test the road trip capability of the vehicle and planned a 60 mile round trip drive to a friend's place. I started the trip with a 100% charged battery and a 75% full gas tank. I drove exclusively on HV mode for 30 miles, parked the car, hung out at my friend's for about 2 hours, and then found that the Clarity would not restart. The key fob works. I can unlock the vehicle and the proximity features work. When I press the brake and the power button the vehicle appears to go onto accessory mode. I can use the infotainment, turn on/off lights, turn on/off the parking brake, etc. However, when I put the car in reverse or drive, I get a message that I first need to start the car by holding the brake and pressing power. When I hold the brake and press the power nothing happens. Nothing I do will start the car. The battery is fully charged and the gas is 75% full. On the dash, the red battery icon is illuminated indicating the 12V battery is not charging. The electric power steering light is also on. I tried jump starting the trafitional 12V battery but still the vehicle did not start. Eventually, I had the vehicle towed to the dealership and they could not start it either. Have any Clarity owners experienced anything similar? I feel like I'm perhaps doing something wrong. The vehicle is complicated, and I wonder if I did something to force the vehicle onto accessory mode. Sadly the dealership is pretty clueless about the Clarity. I'll update this thread with the resolution of the issue. Needless to say, it's extremely disappointing that the Clarity quit working after a less than 500 miles. It's terrible to be stranded by a vehicle failire after 2 weeks of ownership.
