This made me literally lol. The concept of a car having a bad day shouldn't be a thing... But we all know it's possible in our cases
The wake up sequence for the many, many computers in this car is very specific and needs to happen in the exact right order. When that doesn’t happen for whatever reason, your car will indeed have a “bad day.”
It basically wakes up on the wrong side of the bed, so to speak.
I’m convinced the majority of issues that get reported here are due to a bad wake up sequence. I see it every once in a blue moon. But others seem to get it more often.
In most cases, the Air Logo reset will force at least the multimedia portion of the computer system to restart and thus (hopefully) get the sequence correct. That usually fixes whatever issue was happening. At least for me. When that doesn’t do the trick, I usually try a “nuke” reset, and that seems to force everything to start from scratch.
The vast majority of the time, my car wakes up fine, CarPlay connects, and I go on my way. I’ve had a few loaners now, and they’ve all worked well for me, too. So either I’m extremely lucky, or some folks report these “bad days” more often than I do.
This has been the case for literally every computer I’ve owned in my life. Sometimes you just have to reboot and start over.
“Have you tried turning it off and turning it back on again?” was a funny line for a reason.
