No. The results of staring at the voltage on the dic is the driver would have crashed into something while watching the voltage and not watching the road.
We'll never know for sure. But while on the incline, I experienced less than expected power. Having no voltage meter to check, and seeing no lights dim, I said "well, I'll push down a little on the throttle"
That's when all hell went loose. It wasn't enough loss of power to know to stop, but enough I would have checked the meter had it been there. I would not have done a partial pedal-down had the voltage meter told me the car didn't have the right power.
Again, we'll never know if the voltage meter would have sent me that info.
But it certainly could have. And that's why I'll never drive a Kappa again without one.
Dealer just signed off on the car, too late for me to pick it up today - but their conclusion is the voltage regulator in the ECU itself failed - causing the engine to cut and the car to spin out.
They road tested it, so I'm going to pick it up tomorrow and start some very cautious break-in period driving to make sure it's all fixed.
At the end of the day, these new DC-in splitters that have voltage meters on them are a suitable remedy. It's $13.99 for one that you can mount on your dash easily, and gain DC-in ports instead of just one. Would be nice if GM gave them out, but not the hill I want to die on.
I encourage people to pay it (or buy something similar) and have that info available to you.
