here's a thought - take a hair dryer and blow hot air on the ABS controller and CEM to simulate a warm day. If your codes start popping up you may have a thermal expansion issue creating a short or open. You can also do the opposite - buy some electronics cold spray or compressed air in a can (at an electronics store like Best Buy). when you get your codes, spray the ABS controller to cool it off to see if your codes resolve. Do the same for the CEM.

Now have all the original faults/error messages as I originally did...
Check Engine
ABS
DSTC
Park Brake (blinking)
Brake
Red Triangle w/ exclamation mark
DSTC Service Required
Coolant System Required
Park Brake Service Required
Park Assist System Service Required
Power Steering Service Required
Brake Failure Stop Safely
Should I now be leaning toward the CEM???
If so, why after the car sits for a few days, it starts up fine with no codes then after about 10min of running, all come back?
Or could this be all tied to the high voltage output???

Brake Failure stop safely 2013 c70
I have had my car for 8 years and never had issues. I took the dealer and had front brakes replaced and 3 weeks later I started getting this error. VOLVO towed it to the nearest dealer and they kept it a week and saw no issues. I told them about brakes being replaced but they said there were no issues and they could find no codes. It worked for them every time. We picked the car up on Thursday around noon. It cranked perfectly. We drove the car several times on Friday no issues. We drove th car Saturday about 100 miles out of town and got there. No issues. The car sat for a few hours and we headed back to our town got 15 miles outside of town and the car stopped for the same issues. Started with brake failure messages and then it started flashing 4 other codes.
We would not cut the car off so the engine stayed on but nothing else worked. When the tow truck driver arrived it would not even go into neutral. We had to tow the car 79 miles back to the dealership and we had to pay 300 dollars because volvo only covered 25 miles.
This is dangerous and it makes no sense w
hy Volvo doesn't see the issue. It has to be a computer software issue
