I'm not experiencing any other issues where things are acting strangely. Except for an ongoing and possibly related issues where my voltage drops like a rock when coming to a stop. I will create a separate thread on that.

I did a relearn process following the instructions in this link below and it worked! Probably only temporary. Looks like an ignition switch replacement is in my future.
