Auto Start, Shift to Park then Restart Engine error

[jdmduluth]

Anyone else have this issue where when at a stop the Auto Start shuts down completly and this warning light pops up requiring you to shift the car into park then hit the start button before being able to advance to shifting into drive.

how's the battery?

Your battery is going bad. Same thing happened to ours. Same message on the cluster. Top tip.. make sure you disable the ASS (auto start stop) after you start the vehicle. ASS kills batteries especially if you short trip a lot.

Wait you can disable it via Forscan? I always thought you had to wire in a dongle in the back like the one for F150s:

After a week it's muscle memory. Starting is now a two button push!
