Clarity Engine light issue

Hi, all. We just bought a new Clarity PHEV base model last week, and it ran great for the first 268 miles or so. After parking for about 30 minutes outside on a hot (~93F) day, the car started up with almost every diagnostic light on, even though it ran fine getting home:

1. Unable to switch between econ and sport mode
2. Emissions Systems Problem
3. Check engine light
4. Road Departure Mitigation System problem
5. Adaptive Cruise Control problem
6. Brake warning light (strangely, though, the electronic parking brake still works).

We did check to make sure the front-facing radar was not obstructed, but even if it was it doesn't seem to account for the inability to switch between econ/sport mode or the emissions/engine lights.

Anybody encounter the same issue before? We're taking it back in to the dealer next week to have it checked out.

Thanks.
