TSC and Stability Control service indicator comes on, reduced engine power and brakes are applied. DTC C0131 was found. This has occurred several times, and clears after it sits for a while. This is a real safety problem. Lots of other complaints found on line with similar issue. GM has not issues a TSB or recall, looks to be electrical issue or a defective BPMV that should be a recall. This is not a DIY fix, going to the dealership to have it diagnosed or repair. We'll see!!
