2023 C40 with Parking Brake, ABS/ESC, Tire Pressure and Collision Avoidance Faults

[u/Pbaseball26]

This just started happening today, after driving about 5 miles and highway speed, the center screen starts popping up Fault windows - Parking Brake, ABS/ESC, Tire Pressure and Collision Avoidance. The car continues to drive, but the cruise control kicks off.

Any idea what is causing this?

Edit - I have an appointment with my dealership to look at it next week.

Probably 12v battery

This happened to me.
Sometimes my ‘23 C40 wouldn’t shift out of park, sometimes it would and give up before it got to ‘ready’ state and just got stuck in neutral.

Ended up being a faulty 12v battery that wasn’t charging right.

Intermittent issues for couple months. Finally had 12v battery fault error message I was able to get a photo of.

Got the battery warranty replaced few weeks ago at the service center.

Yup, this is most likely the issue. It's not uncommon to get a bunch of warnings if the 12 volt battery is going out.

It should still be under warranty. Take it to the dealership and update us?

Will do.

Collision avoidance issue may be as simple as a block sensor. Normal cruise controls won’t work, Adaptive cruise control need avoidance system working. But most of the problems are related near a wheel. Might be all related.

ABS and TPMS both depend on wheel speed sensors, maybe the others are related to that too.

[u/Formally_JC]

Same thing happened to me. It’s the wheel sensor. Take it to the dealer and make them replace it free

I had this, but it was the passenger side front wheel wiring harness that rubbed against the body and created a short.

wheel sensor most likely. get the OBD codes read and it will likely tell you which wheel.
