After trading in our 08 ESV for a conversion van a few years ago, we finally traded back into a 2010 ESV on Saturday! Wife happy, kids happy, all is good, until....

The drive home. At 11:30pm, on the interstate, some guy in front of me starts swerving all over the road, so I honk the horn and floor it to get in front of him. Just after I pass him I start to decelerate, and I see the RPMs are at zero...

So, luckily the median was wide enough to pull off with plenty of space. So I turn off the power, and try to restart... The engine grunts, and all things electric start acting bizarre... Onstar won't work, HVAC displays fade in and out... Nav screen comes on late... Etc. I stop turning key, think maybe its the alternator, but notice that I have full power to everything. Turn off everything and try again... Sme thing happens.

I try multiple times over the next 90 min while we are waiting for the tow truck.... Always the same thing.

So, I would love the get some opinions and advice on what could have caused this. I was thinking it was any thing from a loose grounding wire, to some type of controlmodule failure to onstar hacking my engine immobilizer

Any feedback would be appreciated!
