Was it raining when you drove it home? Used to have a car (I think '04 or '14 Alero) that was notorious for getting fucky when the wiring harness in the front tire(s) got wet. I don't remember what warning it set off, but replacing the wires was only a short-term solution because all it took was a good rain for it to get fucked up again.

On the flip side, I will never forget a Stacy.

I'd go with "My wife's and my friend" but I'm no expert.
