So 400 miles in and engine light came on. This is what happened. I was running into the library and left the Taos on because I left my 15 year old daughter in the car. By the time I came out it had auto shutoff. I hit the start button and via the engine light was on. WTH??? Nothing in the app stating it needs service. Was really hoping I didn't get a lemon but now between this and the auto start not working, who knows.....goes in next Saturday for autostart already so I'll just add it to the list. Any thoughts on how to fix?

The autoshutoff in park is truly one of the most dangerous features on any new car and I am surprised it passed NHTSA. A situation where EPA trumps safety.

If you didn’t start the car completely and you just did the AC/electronics (Pressed the start button without your foot on the break) the engine light will always be on. I guess it’s a way to show you that the car is not completely cranked

Agreed. However I did place my foot on the brake to restart it. As of right now the light is still on and I think I might stop by an auto zone to have them do a quick read on it since I can't get to the dealer till later next week.

Well at dealer now for engine light, and its the dreaded purge valve. Luckily they have one and will replace it. As for auto start they fixed the key fob but app isn't working. Told to talk to salesperson.

P2421 Evap valve stuck open
Yep, same as mine. Came on at 1000 miles, cleared code, came back on 500 miles later. Took to dealer, they ordered the part, cleared code and stayed off another 5k miles. It came back on again, cleared code and has stayed off for the last 2k miles. I'm not going to have the dealer change out the part, our nearest dealer is 200 miles away and that part has no effect on the drive. Maybe when that part becomes available for $20 like the previous version of that valve, I'll change it out myself :)

I spoke too soon. I'm at 13,300 miles today and this morning on my way to work the MIL started flashing, the EPC light came on, and it said reduced engine power and started shaking violently with any throttle application. I called the dealer and they said to have it towed. Wonderful. Will update when I know more

Turns out it was just the charcoal canister- liquid gas got into it (probably from overfilling) and that set off the MIL and put it in limp mode. It's cleaned out and driveable now while they wait for a replacement part.
