Warnings on dash 2012 C300 4Matic sport

Twice now, out of nowhere I have gotten a dash warning for multiple inoperable. Traction control, lane change, anti lock braking etc, speedometer bounces up and down. First time disconnected battery, went away. Second time yesterday, just left it, went out to car about 29 minutes later, cleaned itself. Car drove fine. Thoughts? Thanks

That combo of errors often relates to a failing wheel speed sensor, broken or corroded reluctor ring, or a broken wire to the sensor. If the problem is intermittent, the system will reset the CEL to off, but the errors are usually stored for retrieval by a scanner. It doesn’t stop you from driving the car, but should be looked into.
