I have a MY18 C2. It has ~700 miles on it.
Started the car the other day after having dinner and the warning lights on the dash went off one by one. Seems that every piece of electronics in the car failed.
I rebooted and the same thing happened. Decided to drive it home as it seemed to run fine. Stopped along the way and restarted again, and now the check engine light /airbag is permanently on.

Havent taken it to the shop yet, but was curious if anyone else has seen anything like this?

Reminded me of my old landrover disco and the three amigo kiss of death.

I would toss a trickle charger on it overnight and see what happens. Left any lights on in the car or anything like that lately?

I had something very similar happen to mine including losing the park sensors and RWS and a "check engine light safe to drive". It happened after I had left the car out in the cold and had started it and moved it only a short distance a few times. After I drove the car for some distance it went away. I am thinking I ran the battery down enough that the voltage dropped below some level that triggered all the lights. Sort of unsettling when it happens though. Let us know if it turns out to be something more serious.

I have a 2018 C4 with 13k miles on it. Your car needs to be run otherwise it will throw tantrums. Just saying.


Sorry that I added absolutely no value to your question.

This. Christmas tree lighting probably indicates low battery.

this is helpful. guess ill have to drive the damned thing. lol

please excuse my ignorance as I have never owned a trickle charger. Ive seen a version that plugs into the cigarette lighter. do those actually work and does anyone have a recommendation?

Thanks in advance.
